Process Verification

Process design results in the design output, following which the process has to be constructed or installed, personnel trained capability studies conducted, and process verification performed. It will therefore be necessary to generate several other procedures dealing with each of these topics. 

Once the process has been commissioned (i.e. set to work) trials can be conducted to optimize the process parameters. When special causes of nonconformity have been removed, process verification can commence. Process verification consists of a number of activities ... 

The data on which the product approval submission is based should be generated during the process verification phase. 

Make provision for recording the identity of devices used in product/process verification.

Typical questions that need to be answered are whether the CQP-based system is well designed (validity), whether activities (procedures, instructions, completion of registration forms) related to the monitoring system are executed properly (verification), and whether conditions (checking temperatures, concentrations, and other quality attributes) of processes are really achieved (production process verification). 

Process Verification. Unless otherwise specified, provess verification used as the inspection shall be subject to Government verification at the time the first batch is prepared and at random intervals during the production, but not less than once during each week of continuous operation. Verification will consist of surveillance of the process and related equipment to determine that practices, methods and procedures are being properly applied, and that the products are produced under the requirements of this specification. A record shall be made of each batch of explosive prepared to insure that the following requirements have been met ...

Radiometers for three-dimensional cure are used for simultaneous multipoint measurements, for setup and process verification of the lamp system. They can be used with UV lamps mounted on a fixed bank or a robotic arm. The collected exposure data (irradiance and total UV energy) are displayed on a computer for each sensor position. A SDCure radiometer is shown in Figure 9.7, and an example of a screen display from a 3D radiometer in Figure 9.8. 

Testing during these verification runs will be more frequent and cover more variables than would be typical during routine production. Typically the testing requirements at the verification stage should be the same or more than the proposed testing for process validation runs. The typical process verification analysis of tabulated product includes the following ... 

The transition from a successful pilot-scale process or research scale to a full-scale process requires careful planning and implementation. Although a large amount of information has been gathered during the development of the process (i.e., process characterization and process verification studies), it does not necessarily follow that the full-scale process can be completely predicted. 

In type 1, process verification is required because of subsequent functional specifications for all products. Surgical equipment, such as scissors and tweezers, contact lenses, and eyeglasses are categorized type la. Diagnostic equipment, such as CT scanners, and treatment equipment, such as infusion pumps for the introduction of solution types of medicine and surgical aid solutions are categorized as type lb. In b, instructions for assembly at the user s site should be... 

In the case of type 3, process verification is required to produce the in-process product as type 1, but process validation is required to manufacture the...

Method validation is the process in which every stage of a new analytical method is subjected to rigorous series of tests to ensure that the method will be able to deliver all the outcomes required of it. The confidence that the method can deliver these outcomes is expressed in terms of statistical probability over the whole analyte concentration range established during the validation process. Verification of a method is a simplified form of the validation process. It involves the testing of a series of method parameters to ensure that... 

Risk assessment deals with data acquisition, verification and monitoring. The collection of data is required and the need for additional data may be identified at any point in the process. Verification and monitoring can help to determine the overall effectiveness of the framework approach, provide feedback concerning any need for future modifications, help to evaluate the effectiveness and practicality of policy decisions and point out the need for new or improved risk assessment techniques (USEPA, 1992a). 

In-process verification of the sterility of filtered gases may be done by constantly bleeding off a trickle of gas through a pressure reducer on the downstream side of the sterilizing filter. The bleed may be filtered through a gelatin membrane, which should be removed daily or at other suitable intervals for incubation and examination for evidence of microbiological contamination.

Small Research Laminator. The Process Development Area (PDA) of FSA received two ARCO Solar-developed laminators at the end of the contract. One of these laminators was modified for use with a strip heater. This configuration, with a boost-and-buck autotransformer power supply, was used successfully for some process verification and materials survey experiments. Assessment of future research needs and present equipment capabilities led to additional modifications of the laminator. 

Kipaiissides et al. [36] have applied suboptimal control to the CSTR emulsion polymerization of vinyl acetate. A mathonatical model was used to develop a simulation of the polymerization process. Verification of the model was done by open-loop bench-scale polymerization. Closed-loop control of monomer conversion via manipulation of both monoma and initiator flow rates was... 

Because of the low concentrations of fissile materials in the HLLW from reprocessing, and since vitrification is an immobilization process, the operation of the PAMELA plant was exempted from control by EURATOM and the International Atomic Energy Agency (IAEA). When higher amounts of Pu are processed, the safeguard concept and procedures applicable to reprocessing will have to be implemented. This involves additional analytical controls, process verification, and enhanced security measures.

The HCF has not previously experienced any major accidents or hazardous situations (e.g., fires, explosions . Minor contamination events of personnel and equipment have occurred in Zone 2 that were satisfactorilv resolved bv removal of the contamination. Some spills in the shielded hot cell laboratory steel confinement boxes during isotope production process verification and development tests did not result in large releases and were mitigated using established spill control and cleanup equipment and procedures. ...

Process verification testing is often called screening. Screening involves 100% auditing of all manufactured products to detect or precipitate defects. The aim is to preempt potential quality problems before they reach the field. In principle, this should not be required for a well-controlled process. When uncertainties are Hkely in process controls, however, screening is often used as a safety net.
