This section GB/T 2951 provisions of the Thermal aging methods. The method is suitable for the most common types of insulating and sheathing materials (shells Of the body, polyvinyl chloride, polyethylene, polypropylene, etc.). 1.1 Normative References The following documents contain provisions which, through reference to GB/T 2951 to the present, constitute provisions of this section. For dated reference documents Member, all subsequent amendments (not including errata content) or revisions do not apply to this section, however, encouraged to reach under this section Parties to research agreement to use the latest versions of these documents. For undated reference documents, the latest versions apply to this section. GB/T 2951.11-2008 cable and the cable Common test methods for insulating and sheathing materials - Part 11. General test side Law --- --- Measurement of thickness and overall dimensions of mechanical tests (IEC 60811-1-1.1993, IDT) GB/T 2951.32-2008 cable and the cable Common test methods for insulating and sheathing materials - Part 32. Polyvinyl chloride mixture Special test methods --- --- Loss of mass test - Thermal stability test (IEC 60811-3-2. 1985, IDT) Test Principle 2 This section does not provide all of the test conditions (such as temperature, duration, etc.) as well as all of the test requirements, they should be on cable Product standards to be defined. Any test requirements specified in this standard can be modified in the relevant product standard cable in order to meet the needs of a particular type of cable.

3 Scope

Test conditions and test parameters specified in this section for the most common types of cables, optical cables, wires and cords insulation and sheathing material.

4 Type tests and other tests

Test methods specified in this part first as the type of test. Type test some pilot projects and trials are often conducted (Such as routine test) conditions are fundamentally different, this section has been pointed out these differences.

5 Pretreatment

All tests shall be insulated and sheath material extruded or vulcanized (or crosslinking) after storage for at least 16h before the test.

6 temperature test

Unless otherwise specified, the tests should be carried out at ambient temperature. GB/T 2951.12-2008/IEC 60811-1-2. 1985 ......
