Abstract (sommario):

Validation is the art of designing andpracticing the designed steps alongside with the documentation. Validation is one of themostimportant steps in maintaining &achievingthe quality of the final product group after batch. The qualification of the equipment and systems are planning to carry out the tests and record the tests. We cannot be manufacturing the product, without an equipment. If the equipment is validated, we can ensure that our product is of the top-quality. Validation of the equipment is known as Qualification. To making different kinds of dosage forms, various equipment’s are used. Here, this article concentrates on the equipment qualification for theTablet compression machine. It gives in detail, qualification steps of the equipment, which is used for the manufacturing process through wet granulation. Qualification, an ideal step for equipment validation, is the action undertaken to demonstrate the intended use and performance of the utilities and equipment.The individual steps of qualification such as design, installation, operational and performance qualification, were done in order to qualify the equipment. Blueprint of equipment validation was also included and the tablets were tested for physical parameters such asappearance, punch Shape, punch diameter, upper punch, lower punch, hardness, weight variation, friability, and thickness.

Abstract (sommario):

Robotic laboratory equipment malfunctions may affect the performance of integrated laboratory instruments. Thus, the qualification of robotics is necessary to ensure adequate performance of complete integrated systems. In this JALA Tutorial, we adapt the methods used in production processes to laboratory robotics and propose guidelines for performing the various steps required for qualification (i.e., installation, operational, and performance qualification), while emphasizing specific aspects of laboratory robotics. We think that the application of such guidelines will help in standardizing the acceptance of robotic equipment, facilitate their operation and performance evaluation, and improve traceability with quality assurance documentation.

Abstract (sommario):

All equipment’s used in the production of products shall be properly Validated, Qualified and Calibrated to demonstrate that it is suitable for its intended purpose. Qualification is an important aspect of the pharmaceutical quality system. When the equipment is properly qualified, verified and maintained, there is the possibility of Consistent performance of the equipment. A well designed qualification program saves valuable time and cost. Qualification is called a cyclic process because it is a never ending process. Appropriate documentation of the qualification program is very important as lack of the documented evidence does not give any meaning to qualification (Not documented it means not done). The current programs and procedures of equipment qualification used within any pharmaceutical and bioscience industry are based on ‘regulatory requirements’, ‘voluntary standards’, ‘vendor practices’, and ‘industry practices’. The output is considerable variation in the way any pharmaceutical and biotechnological companies approach for the laboratory equipment. The lifecycle management approach of equipment qualification covers entire life cycle for the specification, design, manufacturing, installation, commissioning, qualification (4Qs Model DQ, IQ, OQ, PQ), operation & maintenance of equipment in a risk based life cycle management approach. The goal of any regulated pharmaceutical and bioscience company is to provide reliable and valid data suitable for its intended purpose. Main goal of equipment qualification is to form the basis for written procedures for production and process control which are designed to assure that the drug products have the SISPQ (Safety, Identity, Strength, Purity and Quality) Keywords: Validation, Calibration, Life cycle management approach, Qualification (4Qs Model- DQ, IQ, OQ & PQ), SISPQ (Safety, Identity, Strength, Purity and Quality)

Abstract (sommario):

Since its introduction a few years ago the use of the power/response spectrum transformation has gained considerable interest and acceptance, and a number of new applications of the transformation have been developed in the equipment qualification area. A brief review of the power/response spectrum transformation is given with a discussion of the input/output relationships for linear systems required for elevated power spectrum generation. Frequency content of earthquakelike signals is discussed with emphasis on the resolution given by the PSD. The problem of excessive ZPA due to inconsistent spectra enveloping and mechanical nonlinearities is also discussed. The PSD/RS transformation is applied to the problems of combining various dynamic load events, developing bounding spectra, and developing damping consistent test spectra. Development of elevated component spectra corrected for base overtest and generation from in-situ measurements is reviewed.

Abstract (sommario):

In the most general sense, validation refers to a process that consists of at least four distinct components or steps: software, instruments, methods or procedures, and system suitability The system, the software, and the method must all be validated, and system suitability is used to keep the process in check. But while the overall process is called validation, some of the steps also are referred to by that same term, as well as other steps such as qualification and verification. Analytical instruments are used for a specific analysis. So regular performance verifications are made to ensure that the instrument to be used is suitable for its intended application. All equipments used in the production of products shall be properly Validated and Calibrated to demonstrate that it is suitable for its intended purpose. The current equipment qualification programs and procedures used within the pharmaceutical industry are based on regulatory requirements, voluntary standards, vendor practices, and industry practices. The result is considerable variation in the way pharmaceutical companies approach the qualification of laboratory equipment and the way they interpret the often vague requirements. The process for instrument qualification follows the 4Qs model approach. It include design qualification (DQ), Installation qualification (IQ), Operational qualification (OQ), Performance qualification (PQ). The goal of any regulated laboratory is to provide reliable and valid data suitable for its intended purpose. Analysts use validated methods, system suitability tests, and in-process quality control checks to ensure that the data they acquire are reliable and that there are specific guidance and procedures available to ensure compliance.

Abstract (sommario):

The seismic qualification for the structural strength it is an issue for the assessment of the seismic safety of the Nuclear Power Plants. The qualification for seismic events in nuclear industry [4] includes the assessment of the structural integrity and fitness for operability during and after an earthquake. Such qualifications are done for various safety and non-safety equipment among which the pressure vessels are of a paramount importance. The seismic qualification is done either directly on prototypes or scaled prototypes (mock ups) or via analytical methods like analysis with finite elements. In any case the model should accurately represent the actual performance of the component or structure when it is subjected to the prescribed effects. The goal of this article is to underline the procedure to be followed for nuclear industry horizontal pressure vessels in order to obtain sound and credible results for equipment seismic qualification by using the unique analysis features of ANSYS 19. A seismic qualification analysis is carried out for the horizontal pressure vessel. The seismic event is overloading the anchoring system beyond the ultimate strength of the material. The zone where these big stresses fields are calculated is at the anchors level. The vessel as designed failed to be qualified for the seism excitations imposed to the model. In order to have the vessel qualified the anchoring way should be redesigned. By comparing the overall calculated equivalent stresses with the tensile yield strength we may pull the conclusion that the original structure design will fail. Instead the new redesigned anchoring system with 8 extra-anchors will stand.

Abstract (sommario):

Subsea systems designed for continuous operation on the seabed are required to demonstrate very high reliability and it is not uncommon to encounter requirements that state a 10 year Mean Time Between Failure (MTBF) and 20 year design life. While the environment on the seabed is in general quite benign and predictable, the importance of system availability to maintain production and the duration over which reliability needs to be demonstrated becomes a critical issue. This short paper briefly outlines the process, results and lessons learned from over four years of qualification testing, reliability analysis and extended life testing as part of the development of an advanced subsea surveillance system to ensure a final commercial product which shall maintain a high availability through-out its operational lifetime.

Abstract (sommario):

Building codes and standards now require seismic qualification of mechanical and electrical equipment and their mounting systems in important buildings to ensure that they remain functional during and after major seismic events. To better understand the seismic behavior of nonstructural building contents and equipment, experimental procedures have been proposed for either displacement or acceleration sensitive nonstructural components, through racking or shake table protocols, respectively. However, certain types of nonstructural systems are sensitive to both accelerations and interstory drifts. An innovative testing protocol is proposed that can subject nonstructural systems to the combined accelerations and interstory drifts expected within multistory buildings during seismic shaking. Moreover, the proposed protocol, when used with equipment such as the University at Buffalo Nonstructural Component Simulator (UB-NCS), allows for the assessment of the seismic performance of distributed nonstructural systems with multiple attachment points, and the evaluation of seismic interactions between components. The versatility and capabilities of the testing protocol are demonstrated through testing of a full-scale hospital emergency room containing typical nonstructural components and life support medical equipment.

Abstract (sommario):

Electromagnetic compatibility (EMC) in nuclear power plants today mostly relies on the qualification tests of the new equipment and adhering to some good installation practices. Diversity of the electromagnetic environment and different susceptibility of the plant equipment calls for a systematic classification of the EMC zones in a nuclear power plant. The paper proposes a methodology that uses a combination of the qualification tests, in situ and bench immunity tests, site survey measurements, operational experience, and numerical calculations to divide a nuclear power plant into a reasonable number of EMC zones. This would primarily help to have a better overview of the current EMC level in the plant and to unify emission and susceptibility requirements for the new equipment. In this paper, special attention is given to the preparation and performance of the in situ tests, which present the most challenging step of the methodology. In addition, the paper proposes some of the possible applications of the numerical calculations and addresses their challenges and limitations. The novel classification methodology, inspired by the equipment qualification program, is illustrated with examples from Krško Nuclear Power Plant, which recently performed a comprehensive EMC assessment.

Abstract (sommario):

Abstract The oil and gas industry subsurface formation evaluation instruments experience significant challenging vibrations and shock levels. Equipment development requirements for these instruments include reliability and durability under these severe operating conditions. The engineering design for this equipment utilizes tools that enable the estimation of service lifetime, maintenance cycles, and related costs. These engineering tools model failure modes and their acceleration factors and how failures interact under certain circumstances. Laboratory test data and operations failure history are used to validate the model results. Incorporating equipment operational failure history into the reliability design after failure analysis, enables determination of failure modes and the length of stress level exposure. Before the equipment is commissioned to field operational service, it is subjected to a batch of environmental qualification tests under objective pass-fail criteria. The environmental qualification test conditions and adopted stress levels are acquired through measurements made with sensors (temperature, acceleration, and shock) in the equipment assembly during field operational conditions in targeted environments. After the equipment passes the qualification tests and final inspection, it is commissioned to field commercial service. This paper studies the development of specific equipment failures during operational field deployment after they were subjected to standard environmental qualifications tests. Various investigative actions focused on determining the cause and circumstances that led to the unexpected field failure. Results helped to introduce corrective updates to the equipment design and manufacturing, durability and reliability design models and procedures, environmental stress levels, and corresponding qualification test conditions. The equipment failures were examined, and comprehensive 3D custom vibration and stress modeling were conducted for the entire equipment assembly and each assembly module. The modeling results pinpointed and confirmed the high stress levels in the failure areas. These high stress levels exceeded the assembly construction strength thresholds, causing failures. The equipment assembly was modified and reinforced to properly support the detected stresses and provide the required lifetime reliability and durability for the operational service. A full 3D model of the equipment assembly was used for the vibration and bending load analysis including all mechanical assembly parts, electronics modules, couplings, and attachments. The 3D model was meshed with Tet and Hex elements in ANSYS application software, failure-prone and critical regions were meshed with finer divisions. In this analysis the electronics modules assembly were considered with all parts, attachments, structural frames, linkages, carriers, and printed circuit board (PCB) modules properly attached and connected to the main chassis structural carrier. Geometries, mass, module and assembly attachments, and material properties were assigned to components in this model. External loads and boundary conditions environmentally imposed to the assembly were applied in the model. Environmental conditions, shock, and vibration (x, y, and z) recorded from similar equipment deployed in subsurface operations in equivalent wells and geological formations were used in the modeling parameters. Displacement modeling data and analysis was performed for all mechanical structural components, PCB electronics module assemblies and assembly components, and module electronics component attachments. A model harmonic analysis under static conditions was performed to detect the oscillatory modes and vibratory resonances and the extent of oscillatory displacements. A structural and main carrier chassis modal analysis was conducted for the entire model, identifying the dominant oscillatory modes and natural structural oscillatory frequencies. The displacement can be used for detection of maximum allowable plastic deformation threshold and cyclic fatigue analysis of attachments, structural support members, and linkages for equipment service lifetime durability and reliability assessment. Past field instrumented operational conditions with documented failures and lab characterization of failure modes along with failure behavior and failure triggering thresholds have provided limits for the mechanical and electronics assembly technology with maximum acceleration level of random vibration and maximum equivalent stress level tolerated by the equipment's structural assembly, standard design techniques, and materials. With these structural stress and displacement limits the 3D modeling results were inspected for the entire assembly, identifying the points in the mesh model where these limits were exceeded. The inspection determined that these recommended limits had been exceeded according to the model results, placing a reduced importance to the adjustment of tolerable maximum stresses and displacements. The mesh points with excessive stress and displacement-induced fatigue coincided with the areas where field failure had been detected in examined field failed units. Because of this modeled assembly performance result and details from the externally imposed operational shocks and vibration, the equipment mechanical and electronics assembly structural design were re-engineered to produce an updated model simulation results that did not exceed the demonstrated cumulative failure threshold stresses in lab tests and field operations. The modified equipment assembly was built and environmentally re-tested in the lab environment with more instrumentation points and scrutiny around the failure critical areas. The test results were successful. After deployment of the new and updated equipment assembly version, its field deployment has not observed similar field failures compared with the previous design version. These modeling and engineering tools, qualification test procedures, and methods can be used to validate a new design or understand the most effective and economical approach to iterate the design before it is launched to field operations or after a field failure.

Abstract (sommario):

The results of implementing equipment qualification are analyzed. Such equipment is critical for the nuclear and technical safety of domestic nuclear power plants that are especially important for the implementation of the Program for extending the terms of out-of-project operation of power reactors that are capable of being used as powerful sources of electricity. Based on the comparison of published reliability indicators of domestic nuclear power plants before and after implementing the qualification, it is shown that still there are problems to be solved. The perspective of further enhancing the reliability of the operation of domestic nuclear energetics is considered, by implementing radiation functional testing methods that are been developed at the INR NAS of Ukraine for a long period. The basis of this method is detailed research and operational control of all processes that occur in critical equipment in any operating modes of nuclear reactors to form a resource history of the equipment and to provide operational information about the remaining resource and the expected time of its failure to an on-line object operator.

Abstract (sommario):

A general methodology has been developed for correlating the severity of various seismic qualification motions that can have very different dynamic characteristics. The approach is based on a vibrational equivalence concept which allows a severity comparison between two different waveforms. The comparison is in terms of a fragility ratio, DFR, which is a ratio of vibrational input level to that which the specific equipment is capable of sustaining at its fragility level. Measurement of the severity at both levels can be characterized in terms of response spectrum, power spectrum, or other parameters which may be used, or have been used, in typical equipment qualification procedures. Relationships among the various parameters are defined so that transformations from one to another are possible. The inherent use of the fragility function for the methodology causes some problem in that such data are not generally included in previous qualification information. This problem is overcome by defining a lower-bound, or acceptable approximate fragility function, which is based on the previous qualification levels. A method of measuring relative severity of two motions is also developed in terms of a relative severity ratio, DSR. This ratio is proportional to several other relative severity factors that have been established by other researchers.

Abstract (sommario):

One of the urgent problems of modern industrial enterprises is the problem of their technical development. The most common direction of technical development is the technical re-equipment of industrial enterprises. This is a very long and costly process, requiring both from the management of the enterprise and from its employees of high qualification, the ability, and skills to make quick decisions and predict the outcomes of these decisions. Currently, the market for technical and technological equipment is represented by many kinds of different industrial machines, aggregates, mechanisms of different manufacturing firms, different levels of complexity, productivity, energy intensity, and, of course, different costs. The analysis of the market, the choice of suppliers of production equipment, the formulation of terms of delivery and payment, installation, assembly, and installation of equipment at the enterprise, commissioning and subsequent technical support are all elements of the process of renewal of fixed assets called technical re-equipment.Technical re-equipment includes raising the technological level of production, which includes the use of additional new equipment (both in the case of physical and moral obsolescence).During this event, either modified tools will be used in the production of old products, or the quality of the products will change, or a completely new product will be produced, or all taken together. In addition, the concept of technical re-equipment can include the re-qualification of personnel during the re-equipment process and bringing technologies in line with environmental norms and standards.

Abstract (sommario):

ABSTRACT The oil spill response industry is continuously driven to elevate the level of readiness of response personnel. The industry challenges itself to maintain a roster of spill response personnel that are trained and ready to fulfill “specialty functions” and operate “specialty equipment” in the event of a major oil spill. It is easy to respond to questions like: “Who are your oil spill response vessel operators?” or “Who are your response barge crew members?” However, how should one react when presented with the next set of questions: “What are your vessel operators qualifications?” or “How do you determine what qualifies them to perform that function?” Since it provides emergency response, the oil spill response industry is now asked these questions and is required to provide definitive responses. To avoid becoming complacent, it is necessary to provide a training curriculum that goes beyond the basics. A basic training program that simply includes a 24- or 40-hour HAZWOPER course coupled with a course on booming and skimmers will not suffice. The spill response industry is brimming with individuals that possess basic training. Today, to maintain a high state of response readiness, an oil spill training program must offer more than the basic components. To be effective, response personnel must maintain the highest level of competency to ensure readiness when responding to an oil spill. The industry must be confident that it will succeed in its responsibility to operate response equipment efficiently and effectively. It is imperative that the oil spill response industry demonstrates to the governing agencies that it has the personnel with the necessary skills to operate special equipment and fulfill the specialty functions that arise during the course of an oil spill response. If not, the industry is putting the environment and itself at risk. Therefore, Alaska Clean Seas' latest efforts have been directed toward developing a highly competent oil spill Response Qualification System (RQS).

Abstract (sommario):

Acoustic emission testing (AT) is in Europe an already well established non-destructive testing (NDT) method. Qualification requirements as well as certification of testing personnel are laid down in European standard EN 473. A widespread application of AT deals with testing of unfired pressure vessels for re-qualification after a certain period of service (repetition test). The advantages of applying AT compared to the traditional procedure of hydrostatic test plus visual inside inspection are numerous. Just to name the most important: reduction of downtime, omitting of residual humidity and no risk of product contamination with water. It is a fact that AT provides much more useful information concerning the condition of the pressure vessel under test than a simple ‘passed’ or ‘not passed’ obtained usually by a hydrostatic test. This contribution gives two examples of practical experience, where severe corrosion defects have been detected by AT. The defects have been found in both cases on the vessel’s shell under the thermal insulation, where they have been hidden undetected for years. It can be assumed that even the vessel with the most severe damage (loss of more than 50% of the nominal wall thickness) would have passed the traditional repetition test procedure and that failure within the following service period would have occurred. In contrary to this scenario, AT enabled the vessel operator to perform appropriate repair in time.

Abstract (sommario):

In the assessment of the structural integrity and launch-environment survivability of satellite structures, dynamic mathematical models are used for load prediction. These analytical models are test-verified by a modal survey test. Once the vibration environment is specified, the satellite equipment is subjected to shaker excitation in order to reproduce this environment. This paper investigates the possibilities to integrate both the modal survey and the vibration qualification test.
