Cycle development testing

The washing of components will be validated for each load configuration in the vial washer. Cycle Development Testing and Performance Qualification testing will qualify each washing process. A separate performance qualification and cycle development testing report will be written for each load configuration. The processes will be considered validated when the acceptance criteria is met for three (3) successful consecutive runs. 

Perform one or more cycle development test runs with vials to determine appropriate time for each cycle (wash and rinse), temperature for each cycle, load size, WFI supply pressure, and air supply pressure. 

Identify and document the quantity and placement of vials in the load configuration. Determine load configuration from Cycle Development Test studies. 

Perform one or more cycle development test runs used in the load configuration to determine appropriate cycle type, temperature and dwell period, hard-to-heat items or areas, load item preparation, and minimum and maximum load configurations. 

The process engineer also develops tests and interprets data and information from the research pilot plant. He aids in scaling-up the research qpe flow cycle to one of commercial feasibility. 

Vacuum-Steam-Pressure Test. A special aging test which has been used successfully in the USA to accelerate aging to produce the effects of 6-month tropical exposure on certain types of sealed fuzes. It is primarily a development test which can be used during production The test consists of subjecting bare fuzes to 1000 fifteen-minute consecutive cycles in a vacuum-steam-pressure environment. The 1000 cycles takes about 10 days of continuous running time. The basic cycle consists of temperature-humidity cycling superimposed on pressure cycling in a test chamber with a salt laden atmosphere. Representative curves of temperature and pressure are shown in Fig 1... 

Quality-related critical parameters, data, and functions are essential for specification and contract considerations, system design and development, qualification testing of the computer system, and PQ for the validation of the process. GMP-related system requirements need to be traceable throughout the specification, design, development, testing, and operation of a system. This can readily be achieved by having a traceability matrix that will identify corresponding sections and data in the key life-cycle documents. 

Design, development, and system build is normally a period of intense activity, in which a supplier will be involved in life-cycle activities and will need to provide a set of auditable design and development documentation to support the validation program. For this, the entire design and development process should be carried out to written and approved procedures, and all design, development, testing, and verification activities should be documented and approved in order to provide a level of computer system documentation that can be used to support the pharmaceutical manufacturer s life-cycle qualification activities.

Typically, prototypes are discarded once the functional requirements and user interface requirements have been fully defined. The final system is then developed through a prospective fife cycle of design, coding, configuration and build, development testing, and user qualification. QA need not be involved with the development of prototype software since it is destined to be discarded and does not have to have any sigrfificant level of irmate quality. 

Closely related to the D. magna partial life-cycle toxicity test is the three-brood renewal toxicity test with Ceriodaphnia dubia (Table 4.3). The test was developed in an attempt to shorten the amount of time, amount of toxicant, and the cost of performing chronic type toxicity tests. This methodology has... 

Surface Chemistry. The schedule of sample exposure during the first year of the test program was as follows for each three-month period, briquettes were exposed in racks and then replaced with fresh samples for the following three-month period. An additional set of briquettes was exposed for the entire year, and other samples present in the racks are part of a planned multiyear exposure program. Quarterly withdrawals for chemical analysis are to be made for two years, after which a cumulative annual frequency is to be maintained. One set of samples is continuously exposed for posterity or for unforeseen developments. Three samples of each stone type are employed in each cycle of tests. The plan is subject to change in the light of analysis results as they are produced. 

Critical processes other than the actual product manufacturing process — such as sterilization, component washing, and equipment cleaning — require prevalidation cycle development work. This may include establishment of appropriate sterilization cycle types, cleaning agents, etc. This test work is performed during or after Operational Qualification. 

Record the range of all process or equipment parameters (set points, flow rates, timing sequences, concentrations, etc.) verified during cycle Development and Performance Qualifications testing.
