E-Test method

E-tests can be used to determine MIC for fastidious organisms such as Streptococcus pneumoniae, P-haemolytic streptococci, Neisseria gonorrhoeae, Haemophilus sp. and anaerobes. It can also be used for non-fermenting Gram-negative bacilli, e.g.. Pseudomonas sp. and Burkholderia pseudomallei. 

Antimicrobial resistance of major consequence may be detected, e.g., the test is very useful in detecting glycopeptide-resistant enterococci and glycopeptide-intermediate Staphylococcus aureus and slow-growing pathogens such as Mycobacterium tuberculosis. Furthermore, it can be used for detecting extended spectrum P-lactamases. In conclusion, the E-test is a simple, accurate and reliable method to determine the MIC for a wide spectrum of infectious agents [33, 34].

Test Method B Straight Normalization Procedure—A portion of the sample is injected into the chromatograph using a microlitre syringe at the specified conditions of e test method. The area of all the peaks and main component are electronically integrated. These areas are normalized to 100.00 %. 

With this testing method an evaluation is possible within shortest time, i.e. directly after the heat impulse. The high temperature difference between a delamination and sound material is affected - among other parameters - by the thickness of the layer. Other parameters are size and stage of the delamination Generally, a high surface temperature refers to a small wall thickness and/or layer separation [4],...

The main conclusion of an expert workshop on endocrine modulators and wildlife in 1997 was that some existing test methods, as defined in guidelines published by the Organization for Economic Cooperation and Development (OECD), could be adapted to incorporate specific endocrine disrupting endpoints, but that there might also be the need to develop new tests, e.g. for fish. On behalf of the UK Government, the MRC Institute for Environment and Health (lEH)... 

ASTM E 1226. Standard Test Method for Pressure and Rate of Pressure Rise for Combustible Dusts. 

Maximum Pressure and Rate of Pressure Rise and KJ These explosibility parameters are used in assessing whether equipment will contain the maximum pressure developed during deflagration, or to design deflagration relief vents and other explosion prevention systems (see NEPA 68 and 69). The test method is given in ASTM E 1226. 

In the case of crystalline polymers such as types E and F the situation is somewhat more complicated. There is some change in modulus around the which decreases with increasing crystallinity and a catastrophic change around the. Furthermore there are many polymers that soften progressively between the Tg and the due to the wide melting range of the crystalline structures, and the value determined for the softening point can depend very considerably on the test method used. 

EN 779 1993 in principle contains two different test methods. The filter is tested both with untreated outdoor air and with the addition of synthetic dust. In the first case, the filter s dust spot efficiency is determined, i.e., its capacity to clean normal outdoor air. In the second case, the filter s arrestance is measured, i.e., its capacity to separate synthetic dust. The average value for dust spot efficiency or arrestance during the course of the test is used for classification of the filter. 

Under micro-discontinuous chromium coatings, copper undercoats improve corrosion resistance. On non-conductors, especially on plastic substrates, copper is often applied before nickel-chromium plating over the initial electroless copper or nickel deposit in order to improve ductility and adhesion, e.g. as tested by the standard thermal-cycling test methods ... 

In analysis of variance, the variance due to each source of variation is systematically isolated. A test of significance, the E-test, is then applied to establish roughly how seriously one must regard each source of variation. The interested reader is urged to consult books on statistics14 for discussions of this valuable statistical method.
