5 Tests
5.1 General
5.1.1 Atmospheric conditions for tests
5.1.1.1 unless otherwise stated in a test procedure, conduct the testing after the test specimen has heen allowed to stabilize in the standard atmospheric conditions for testing as specified in IEC 60068-1 as Follows:
— temperature: (15 to 35) °C;
— relative humidity: (25 to 75) %;
— air Iwessure: (86 to 106) kPa.
5.1.1.2 The temperature and humidity shall be substantially constant for each environmental test where the standard atmospheric conditions are applied.
5.1.2 Mounting arrangements
The specimen shall be mounted by its normal means of attachment in accordance with the manufacturer’s instructions. If these instructions describe more than one method of mounting, then the method considered to be most unfavourable shall he chosen for each test.
5.1.3 Operating conditions for tests
5.1.3.1 If a test method requires that a specimen be opei’ational, then the specimen shall be connected to suitable supply and monitoring equipment with characteristics as require(I by the manufacturcrs data. Unless otherwise specified in the test method, the supply parameters applied to the specimen shall be set within the manufacturer’s specified range(s) and shall remain substantially constant throughout the tests. The value chosen for each parameter shall normally be the nominal value or the mean of the SI)CCified range.
5.1.3.2 The details of the supply and monitoring equipment used shall be given in the test report; see Clause 8.ISO 7076-6:2016 pdf free download.
