Electric and optical fibre cables. Test methods for non-metallic materials - Mechanical tests. Test for resistance of insulations and sheaths to cracking (heat shock test)1 Scope This Part 509 of IEC 60811 gives the procedure for the test for resistance of insulations and sheaths to cracking at an elevated temperature.

which is intended to establish whether the stated measurable parameters have been met (e

The method is mainly applicable to woven textile fabrics including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre and mechanical or chemical treatment
