Scope

1.1 Scope
GB/T 2951 specifies the test methods to be used for testing polymeric insulating and
sheathing materials of electric and optical cables for power distribution and
telecommunications, including cables used on ships and in offshore applications.
This Part of GB/T 2951 specifies the methods for the ozone resistance test, hot set
test and mineral oil immersion test, which apply to elastomeric compounds of wires,
electric cables and optical cables.
