Verified Test Results.Part

The actions you have to take after receiving positive, adulterated, or substituted test results were covered in Part 382. But what about other results, such as dilute, invalid, or cancelled These possibilities are discussed in 40.23 What actions do employers take after receiving verified test results . 

Testing at stress condition is performed to determine the ability of the system to remain stable at all times during operational conditions defined as continuity. Create stress conditions to determine the span of control for an individual system or rooms. Execute temperature, particle counting, etc. Verify obtained results with adequate operational conditions and determine whether the system is acceptable if it is not, then alert systems are set to report the unacceptable condition. Determine the ability of the system to recover after an unacceptable limit has been reached. Stress testing and alert systems for hardware and software are an important part of the scope of work for the validation team. 

The interpretation of the term maybe present in terms of the statistical confidence in the screening test result depends on the performance characteristics of the assay and the verification of reliable performance by a body of actual test application data. Nonetheless, the confirmation that the test substance actually is present in the sample requires independent determination. For method development purposes, screening tests should be considered a part of an analytical system for a given substance, where the complete system consists of a separate confirmatory technique to verify the initial screening result. 

Predictable, verifiable material property data about a compounded material are typically available from the compounder or resin supplier. These documented test results from molded plaques may help justify a material s suitability, yet it is the properties of the final product that matter to the customer and the long-term reputation of the molder. With highly reinforced resins, questions may remain about local variations in a molded part s final mechanical properties (and gaining answers to these questions by waiting for part failures is not a solution most customers would accept). 

Split specimen In drug testing, the part of the urine specimen that is sent to a first laboratory and retained rmopened, and which is transported to a second laboratory in the event that the driver requests that it be tested following a verified positive test of the primary specimen or a verified adulterated or substituted test result. 

Examples of these requirements include the need to check that an instrument is being used within the stated environmental conditions and application restrictions of the manufacturer. Specific requirements are made to check for compatible materials whenever any part in a safety instrumented function has process wetted parts. A planned comprehensive testing program with written test results is required. A periodic inspection and test plan must be created and verified. 

The last part of this work was the experimental characterization of the whole system. The photomicrosensors and gradation sheet were tested and the integration feasibility of the PSD into the homing sensor system was verified. Finally, both testing results were compared in order to verify the suitability of both measuring systems integration. 

The thermal model of the PM motor is built in Amesim software to analyze the temperature variation of the each part of motor. The simulation is carried out under the same condition of the test platform. The thermal simulation model of PM motor is verified by the test results. A coohng network system composed of the thermal model of PM motor is co-simulated in Amesim and Matlab. In the future research, the motor thermal performance will be investigated with the running conditions of the vehicle. 

The environmental stress cracking is the most common failure reason of polymer parts during their use. There are already many tests to verify the stress crack resistance. Most methods use combinations of an external strain and aggressive liquids to achieve a quick test result. The extrapolation to longer time periods is only successfiil with the help of the expert knowledge of the raw material producers. The development of a new testing method enables a simulation of the material long-term behavior on the basis of a short time test of plastics under the influence of a medium. 

To verify the results of the FE thermal analysis model experimental verifications are needed. This will be carried out relative to the benchmark part for which a DMLS mold has been made using the 50 microns powder. The mold has incorporated within it pressure and temperature sensors. The tool is built in a similar manner to a conventional injection mold, based on a standard 1730 steel material. Long run injection cycle tests were applied, using Kistler temperature and pressure verification [6]. 

What details did you notice in excerpts 3K and 3L Did you notice that both excerpts included the mass and moles of solid reagents, reaction times and temperatures, descriptions of the products (a solid, a white powder), and product yields Both excerpts also included results from tests used to verify product purity and composition. The first included mp, IR, NMR, and mass spectral information the second included only mp information. Perhaps you were surprised to see such results in the Methods sections. Synthetic chemists include such analytical information as part of the procedure, in the Methods section, rather than as a result, in the Results section. The formatting shown in excerpt 3K is typical for the presentation of such data. 

As a test problem for comparing the various methods described above, we have chosen a heptamer island on the (111) surface of an FCC crystal. Partly, this choice is made because it is relatively easy to visualize the saddle point config-mations and partly because there is great interest in the atomic scale mechanism of island diffusion on surfaces (see for example reference 60). The interaction potential is chosen to be a simple function to make it easy for others to verify and extend om results. The atoms interact via a pairwise additive Morse potential... 

It is very important to test and qualify models in a library, rather than assuming that they are accurate. The library governs the accuracy of the simulation in which they are used. Just because a model is in a library does not mean that it provides correct results or that it has been verified over even a small portion of the operation range of the real part.
