This part of IEC 60794 defines test procedures to measure the shrinkage of the sheath due to thermal exposure of cables.
A first test method, F11A, is included for cables where the fibre or buffered fibre and the sheath of the cable are intended to be fully terminated into a connector at one or both cable ends.
A second test method, F11B, is included in this document for sheath shrinkage testing for general purpose.
See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements.
