Question:
$ w0 f* H% O3 j" @: n+ z6 i/ IClause 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”.
3 t  W7 j' X) I% [) u/ y' qThe 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.
