International verification processes

In addition, Analex-Denver, in designing the IV V process, did not understand the generation or internal verification process for all the constants in the truth baseline provided to them by LMA. The Analex-Denver engineers were not aware that the II filter rate values provided originated from a manual input and might not be the same as those subjected to independent V V by Analex-Cleveland. 

GLP regulations require QA personnel to inspect/audit each study conducted, but the extent to which QA personnel are involved in software development and the val-idation/verification process varies from company to company. In some companies, there is little or no QA involvement in these processes, whereas in others QA personnel are involved. QA personnel can provide assistance in the area of vendor audits for purchased software or can conduct inspections of in-house software development to ensure that internal procedures are being followed. QA personnel, who conduct in-process inspections and review the resulting data and validation report for accuracy, could provide inspection support during the validation and verification process. During system development and validation, properly trained QA personnel can provide the regulatory advice needed to ensure that the system will meet government standards. QA personnel become more familiar with the system(s) that will be used when they are involved early in the validation process. 

Fully understanding this accident requires understanding why the error in the roll rate filter constant was introduced in the load tape, why it was not found during the load tape production process and internal review processes, why it was not found during the extensive independent verification and validation effort applied to this software, and why it was not detected during operations at the launch site—in other words, why the safety control structure was ineffective in each of these instances.

Safety-related controllers in conjunction with safety or fail safe I/O modules are used for critical and hazardous applications where an incident can result in danger to persons, and/or damage to plant and environment. These safety-related controllers can work with the safety-related distributed I/O system (may be with internal verification for input or output via safety switches as described in Clause 5.0.1—safe PLC approach), or directly with fail-safe transmitters cormected via the fieldbus. These controllers are supposed to detect faults both in the process and their own internal (self-diagnosis) to the system. It is the duty of the same to automatically set the plant to a safe state in the event of a fault. These controllers need to work in multitasking environment — may be in a mix of standard BPCS or safety-related applications, if integrated operation is permitted by the end-user. The programs of BPCS and SIS must be functionally separate, so that faults in BPCS applications have no effect on safety-related applications and vice versa. Special tasks with very short response times can also be implemented [14]. For safety applications controllers and I/O modules need to individually certified by third party and to comply SIL 2/SIL 3 (as the case may be — SIL 4 only for nuclear application) as per lEC 61508. For safety-related applications a few restrictions are followed such as ...

Article VI concerns Activities not prohibited by the Convention . It provides that states have the right to develop, produce or acquire toxic chemicals and their precursors for purposes not prohibited by the Convention . It also provides that the chemicals to be listed in the Annexes to the Article, which could be used for prohibited purposes, should be subject to international monitoring. States are required to declare data on the relevant chemicals and on their production facilities when the Convention enters into force and annually thereafter. They are required to permit routine systematic international verification through on-site inspection and the use of instruments as long as production and processing are not impaired .

The second module. Method, involves determining the level of verification and validation to which the user s methodology has been subjected. Verification is the general process used to decide whether a method in question is capable of producing accurate and reliable data. Validation is an experimental process involving external corroboration by other laboratories (internal or external) of methods or the use of reference materials to evaluate the suitability of methodology (1). A menu of choices includes (1) the method has only been verified, (2) the method has been both verified and validated, or (3) the method has been neither verified or validated. 

The process of specification should always be subjected to verification to ensure accuracy and meaning in the data provided. Even without recourse to full-scale calculation of the solution, internal consistency of the geometry can be checked, as can closure of curves or overlap of distinct components, whereas physical properties can be matched, say, with tables of established values representing material properties, or compared against experience accrued by modellers. In Figure 15.1 each operational component is connected multiply and reversibly with other components, illustrating the practical side of modeling, where one is often required to repeat steps to correct, clarify, or modify actions taken previously. 

Knowledge of the most common licit uses of substances in Tables I and II of the 1988 Convention, including the processes and end products in which the substances may be used, is essential to the verification of the legitimacy of orders or shipments. The most common licit uses of those substances reported to the International Narcotics Control Board are as follows ... 

Detailed review of reported data reduces laboratory risk of producing invalid data. Important features of internal data review are the spot checks of calculations the verification of the acceptability of calibrations and laboratory QC checks and the second opinion in data interpretation. Laboratories document internal review in appropriate checklist forms that are kept on file with the rest of the project documentation and sample data. The internal data review process is generally described in Laboratory QA Manual and detailed in appropriate SOPs.

The role and use of reference materials are in principle well known, in particular for Certified Reference Materials (CRMs) used as calibration materials or matrix materials representing - as far as possible - real matrices used for the verification of the measurement process, or (not certified) laboratory reference materials (LRMs also known as quality control (QC) materials) used, for example, in interlaboratory studies or in the maintenance of internal quality control (control charts). Examples of reference materials relevant to WFD monitoring (water, sediment and biota) are described in the literature (Quevauviller, 1994 Quevauviller and Maier, 1999).
