Philosophy for testing

It is necessary to evaluate the plates fully over a range of clinical applications and this draws attention to need for an adequate philosophy for testing new implant materials. [Pg.403]

Some users/consultants, however, are of the opinion that by this method the other phases are not subjected to the same severity. Accordingly, they prefer to consider the phase that is subjected to the least fault current as the base. Accordingly, the test duration should be adjusted for this phase. In the above case, the minimum severity has occurred in phase R, with only 39.6 kA. According to this philosophy the test duration should be enhanced to... [Pg.433]

A validation plan should be developed that describes the purpose of the system including subsystems, responsible persons, test philosophy and a schedule for testing. [Pg.50]

Several approaches are possible, for example, mechanical tests or electrical tests, or again, tests on flexible or on rigid materials, but in discus.sing the philosophy of testing a broader classification is needed. A useful approach is that given by Brown (ij in an earlier volume, namely. [Pg.7]

This paper has presented and tested a design philosophy for the synthesis of mass exchange networks whereby an MINLP approach is integrated with pinch analysis tools. At the heart of the integration is the use of pinch-based total cost targets to evaluate the optimality of MINLP solutions and driving force diagrams to identify different initial solution structures. [Pg.232]

Finally, the previous sections have discussed the methodology used to perform finite element prediction of the fatigue life of Sn-Ag-Cu solder joints in an accelerated test environment. The determination of the acceleration factor between accelerated test and product environments is an equally important component of the accelerated testing philosophy. For traditional high-lead solder interconnects, this has been performed with the Norris-Landzberg equation. [Pg.222]

It is important to design in the testing facilities from the start and to do this we need to define the testing philosophy for each function. [Pg.241]

Bridgman had strong views on the importance of empirical research, influenced as little as possible by theory, and this helped him test the influence of numerous variables that lesser mortals failed to heed. He kept clear of quantum mechanics and dislocation theory, for instance. He became deeply ensconced in the philosophy of physics research for instance, he published a famous book on dimensional analysis, and another on the logic of modern physics . When he sought to extrapolate his ideas into the domain of social science, he found himself embroiled in harsh disputes this has happened to a number of eminent scientists, for instance, J.D. Bernal. Walter s book goes into this aspect of Bridgman s life in detail. [Pg.173]

A convenient size for a circular coupon is 3 8 cm dia., a thickness of 0 - 32 cm and a central hole of 1 1 cm. Although inherent in the philosophy of corrosion testing, the use of coupons with surfaces that simulate those in service has been found to be unsatisfactory owing to irreproducibility, and the standard procedure normally adopted is to abrade down to 120-grit. ASTM Method G4 1984 gives details of preparation of specimens, evaluation of replicate exposures and the application of statistical methods. [Pg.1067]

The same basic philosophy as above was applied to the development of a high-pressure high-temperature (HPHT) dynamic service-realistic test facility for seals. This facility provided the means... [Pg.632]
