IEC 60811-4-2 Ed. 2.0 b PDF

IEC 60811-4-2 Ed. 2.0 b – Insulating and sheathing materials of electric and optical cables – Common test methods – Part 4-2: Methods specific to polyethylene and polypropylene compounds – Tensile strength and elongation at break after conditioning at elevated temperature – Wrapping test after conditioning at elevated temper

Specifies the test methods for testing polymeric insulating and sheathing materials of electric and optical fibre cables for power distribution and communications, including cables used on ships and in offshore applications. These test methodsapply specifically to polyolefin insulation and sheath. The principal changes with respect to the previous edition are listed below: a) A measurement of tensile strength is included in Clause 8. b) Clause 10 is now the only method in IEC 60811 for wrapping test after thermal ageing in air. c) Two ageing conditions are now specified for the long-term stability test in Annex A.
