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.

You also get greater flexibility while designing and integrating new products and composing systems with components as well
