This is why If applicable has been added to the titles Initial measurements and Final measurements . When the test is carrie
39、d out individually, the measurements are applicable so that the effect of the test on the performances of the specimen can be evaluated. When the test is included into a test file, the initial and final states of the specimen shall be checked at the beginning and the end of the test file. The initia
40、l and final measurements indicated in each test method are thus not applicable to each test. 4.2 Unless otherwise indicated in the test method, technical specification or product standard, the test conditions shall be as follows: The temperature and humidity shall remain constant throughout a series
41、 of measurements. Unless otherwise indicated in the technical specification, the cables used for the tests shall be in accordance with EN 2083 and EN 2084 or EN 2234 and EN 2346. 5 List of test methods See Table 1.
