ISO 6722-1:20110 pdf download.Road vehicles -60 v and 600 v single-core cables — Part 1: Dimensions, test methods and requirements for copper conductor cables.
4.5 General test conditions
Unless specified otherwise, the device under test (OUT) shall be preconditioned for at least 16 h at a room temperature (RT) of (23 ± 5) C and a relative humidity (RH) 0145 % to 75 %. Unless specified othewise. all tests other than in process” tests shall be conducted at these conditions
Where no tolerance Es specified, all values shall be considered to be approximate.
When ac. tests are performed, they shall be at 50 Hz or 60 Hz. Applications at higher frequencies may
reqwre additional testing.
4.6 Ovens
An oven with air exchange, either natural or by pressure, should be used. The air shall enter the oven in such a way that It flows over the surface of the test pieces and exits near the top of the oven. The oven shall have not less than 8 and not more than 20 complete sir changes per hour at the specified ageing temperature.
Forced air circulation, e.g. by a fan inside the oven may be used. However, in case of dispute, an oven wthout forced air circulation shall be used.
4.7 Representativ, conductor sizes for testing
When a test is required, all combinations of conductor size. wall thkness. and InsLiatlon formulation shall meet the appropriate requirements. However, if testing of representative conductor sizes Is permitted (see Table 3). complIance for a cable family may be demonstrated by testing examples of large and small conductor sizes only. Permission 10 show compliance for a cable lamely by testing representatrve conductor sizes” shall be established by agreement between customer and supplier.
