6 |* ^0 o% W3 t+ `+ ?; jQuestion:
Clause 13.2 of IEC 60598-1 is applicable for tests on lighting chains, that: “for flexible pipes of sealed
chains the test of 13.2.1 is replaced by the test of clause 8 of IEC 60811-3-1”.
The standard doesn’t indicate at which temperature the test of clause 8 of IEC 60811-3-1 shall be
performed, so we have seen different positions from Test Houses for PVC sealed chains.
2 ?* m# f  e) _4 W' BDecision:
The test shall be performed at the temperature measured on insulating tube during the normal heating test
+ 10°C with minimum of 80°C.
