Equipment specification sample testing

The procedures developed for the analysis of the minerals and inorganics were the result of an extensive series of tests to determine the optimum conditions for these specific sample types. This was then combined with general procedures for the analytical equipment. 

Specific tests are available to determine the presence of diazinon or its breakdown products in blood, body tissue, and urine. These tests are not routinely available through your doctor s office and require special equipment and sample handling. If you need the specific test, your doctor can collect the sample and send it to a special laboratory for analysis. This test is only useful if done within a few hours or days of exposure. This is because diazinon is rapidly broken down and excreted from the body. For more information on how to determine if you have been exposed to diazinon, see Chapters 2 and 6. 

The instructions embedded in computer program(s) either provide information on what the operators are supposed to do, or information on how the equipment or processes are intended to function. For example, for manufacturing operations, the batch production and control records may provide procedures, controls, instructions, specifications, and precautions to be followed when using computer systems. These programs may also contain control data for product formulation, batch size, yields, and automated in-process sampling/testing procedures. 

The main point about accreditation is that the laboratory must be able to satisfy an independent outside official body that the work it does is consistently of a quality appropriate for the purpose intended. So, a laboratory that is accredited for some or all of its work, is subject to regular inspections by the accreditation agency. The laboratory has to keep extensive documentation to show that all the requirements of the specifications for accreditation are met on a continuous basis. For example, it has to keep up to date evidence of staff competence and training, performance of equipment and the test results for reference samples (see the UKAS website http Iwww.ukas.com). 

The inspection facilities and equipment must be suitable for the control of manufacture, and able to meet the contract quality specification, i.e. main laboratory and/or line testing areas, measuring equipment, component function testing equipment, sample storage, calibration and validation procedures. 

Tensile, flexural and impact tests were performed based on the ASTM D-638, ASTM D-790 and ASTM D-256 standards respectively in order to analyze the effect of adding nano-CaC03 particles on the mechanical performances of PP/ CaC03 nanocomposites. For each compound, 5 samples were tested and the mean values were considered. The specifications of testing equipment and conditions are presented in table 3. 

A5.1 Check the assembled apparatus, including the previously calibrated pressure measuring and temperature sensor and associated instrumentation, to indicate proper assembly and operating control. Conduct the test procedure as described at the test pressure in connection with a specific sample or at two or more pressures in connection with general checks of the equipment, using u-hexadecane or /i-tetradecane. 

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... 

Insufficient testing is one of the major causes of method failure. The amount of data needed to publish a new procedure in a peer-reviewed journal and the procedural detail supplied therein are often insufficient to allow a different user to validate a method rapidly. The developer should evaluate if the method will work using chemicals, reagents, solid-phase extraction columns, analytical columns, and equipment from various vendors. Separate lots of specific supplies within a vendor should be evaluated to determine if lot-to-lot variation significantly impacts method performance. Sufficient numbers of samples should be assayed to estimate the lifetime of the analytical column and to determine the effects of long-term use on the equipment. 

The section on components deals with all materials that may be used in the manufacture, processing, and packaging of drug products, plus materials used for maintenance of the building and equipment. They must be stored and handled in a safe, sanitary, and orderly manner. These precautions are needed to prevent mix-ups and cross-contamination of drugs and drug products. All items should be held until they have been sampled and tested according to the company s specifications and not released until the tests have been completed. In this section it is required that ... 

An industrial standard method has been developed to test the lightfastness of polymers in accelerated test equipment [103]. The apparatus consists of a quartz-xenon tube with a special optical filter between the light source and the specimen to produce light that resembles window glass-filtered daylight [104], Samples are mounted at a specific distance from the arc and are supported on a frame which revolves around the arc 1 to 5 times per minute for uniform exposure. A blower unit in the base provides a flow of air which makes it possible to maintain a black panel temperature of 45°C, measured by a black panel thermometer which is positioned at level with the samples. A black panel unit consists of a bimetallic thermometer mounted on a steel frame. Both faces of the frame plate and also the stem of the thermometer are coated with a heat-resistant glossy black enamel. The relative humidity level in the exposure cabinet is closely controlled. 

Two types of kits are discussed in this section, sample collection kits and field test kits. Sample collection kits will generally contain all sample containers, materials, supplies, and forms necessary to perform sample collection activities. Field test kits contain the equipment and supplies necessary to perform field safety screening and rapid field testing of the air, water, and/or soil. Sample collection kits will generally be less expensive to construct than field test kits. Sample collection kits can be pre-positioned throughout a system, while the more expensive field kits may be assigned to specific site characterization teams or personnel.
