Processability testing requirement

In-process testing is especially critical, if the material being produced is to be used for human consumption. The types of in-process testing requirements will vary with the process. However, following is a brief description of the types of the in-process testing requirements of a solid-dose manufacturing process. [Pg.323]

In-process testing requires robust methods that are fairly quick and easy to perform. The decision to include an IPC sampling point is based on scientific judgment to ensure product quality, maximumS yield, process efficiency, batch... [Pg.399]

In-process testing requires robust methods that are fairly quick and easy to perform. Samples that arrive at the lab during off-hours may not have an experienced analyst who is usually available during the day shift to perform a complex analysis. The use of new analytical technologies during early process development may be suitable for IPC analysis however, as the process development continues to the technical transfer, alternative methods should be developed that are compatible with QC lab capabilities. In addition, analysts should not try to optimize the method to generate other information that is seldom used in a normal manufacturing operation. [Pg.404]

Subsequent to processing, an inspection is made for incomplete bonding, inside dirt, and glass quaUty. In the case of windshields, rigid optical standards must be met, and these must be evaluated for the completed windshield. Extensive test requirements are described in the appropriate codes (11,12,15,18—24), and they include light stabiUty, resistance to optical distortion, humidity, boil test, abrasion resistance, and assorted impact tests. [Pg.527]

The review should emphasize developing an understanding of the processing sequence, the equipment, the equipment plot, the operating conditions, instrument and sample locations, the control decisions, and the operators perspectives. Wmle the preparation effort may be less for those who have been responsible for the unit for a long period of time, the purpose of the test requires that the types and locations of the measurements be different from those typically recorded and typically used. The condition of these locations must be inspected. Operating specifications may be different. Therefore, refreshment is always necessaiy... [Pg.2552]

All coils that are subjected to this test must fulfil the test requirements. In the case of a failure, investigations must be carried out to establish the cause and the same rectified before undertaking the insulating process on the next batch of coils. [Pg.262]

One will appreciate that such tests are no guarantee of the minimum life of a capacitor unit. Moreover, it is not expected that such tests can predict the future of the capacitor units. They can, at best, suggest the compliance of the test requirements which should ensure a reasonably prolonged operating life of the capacitors, as envisaged. These tests do provide feedback to the manufacturer on the t uality of the dielectric and the process of insulation adopted and if iiny improvements are required. [Pg.841]

In designing an alloy, polymer chemists choose candidate resins according to the properties, cost, and/or processing characteristics required in the end product. Next, compatibility of the constituents is studied, tested, and either optimised or accommodated. [Pg.11]

The requirements pertain to your customer verifying product purchased by you either at your supplier or on your premises. Verification of purchased product is normally carried out by the supplier before or after receipt as part of the purchasing process but may also be carried out by the customer. However, due to the standard locating most of the inspection and test requirements in clause 4.10, the receipt inspection requirements are displaced. [Pg.329]

In defining your inspection and test requirements it is necessary not only to specify what inspections and tests are required and when, but also to define the acceptance criteria and the frequency of inspection and test. Are the acceptance criteria those defined in the product specification or are the limits to be closed to gain better control over the process Is every product to be inspected or are the quantities so large that it would be economically unviable If sampling is to be performed what are the acceptance criteria Answers to these and other questions need to be provided by your documented inspection and testing requirements. [Pg.378]

If we compare liquefaction to maceration, more activities are needed to liquefy the cell wall. Since 1991, new pectinases activities such as rhamnogalacturonase, pectin acetylesterase and xyloglucanases complex have been found to be important in the apple liquefaction by Henck Schols, Jean-Paul Vincken and Voragen [3]. The cellulose-xyloglucan complex accounts approximatively 57% of the apple cell-wall matrix. In a liquefaction process, an efficient enzymic degradation of this complex is crucial to increase the sugars extraction, to decrease the viscosity of the pulp then to be able to ultra-filtrate the juice without second depectinisation, at last to have negative alcohol tests required by some concentrate customers. [Pg.457]

OS 68] [R 19] [P 50] A numbering-up of five mini mixers, tested at the pilot stage, was used [134]. Automation of the entire process was required liquid-flow splitting to the single reactors was ... by no means trivial... [134]. The capacity of one mini reactor was 30 ml s , i.e. 1081 h . The complete setup hence should be operated close to 5001 h . The micro-reactor plant was operated at intervals as the preceding step was carried out batchwise. The operation of the micro-reactor plant started in August 1998 after a period of only about 1.5 years for development. [Pg.520]

Time based commands start processes that require control over a period of time, as in operations that must be repeated at regular intervals. Flow control commands let the control program choose alternative execution paths as needed. They are used to test for the existence of specified process conditions and to change the reaction conditions by branching to other parts of the formula table. [Pg.182]

Process equipment design and materials must be documented by identifying the applicable codes and standards (e g., ASME, ASTM, API). If the codes and standards are not current, the DOE contractor must document that the design, construction, testing, inspection, and operation are still suitable for the intended use. If the process technology requires a design that departs from the applicable codes and standards, the contractor must document that the design and construction are suitable for the intended purpose. [Pg.16]

In most chemical process industries, both qualitative and quantitative analyses are performed on many varieties of company products and the raw materials that go into these products. Some of the qualitative tests require a simple mixing of the test sample with a reagent to produce a color change. One such test can be run, for example, to confirm the contents of drums of tribasic calcium phosphate, which is a raw material for some pharmaceutical products. The test sample is dissolved in water, acidified, and then tested with a molybdate solution. A yellow precipitate indicates that the material is indeed tribasic calcium phosphate. [Pg.4]
