Cables and cable insulation and sheathing materials
Common test methods
Part 14. Common test methods --- Low temperature test
1 Scope
GB/T 2951 provides power distribution and communication cables and fiber optic cable, including marine and offshore cables and cable insulation and jacketing polymer
Test methods for materials.
This section GB/T 2951 specifies the low temperature test methods, and polyvinyl chloride and polyethylene insulation for wire, cable and fiber optic cable
Jacket material.
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 references, the latest version applies to this Part
Minute.
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)
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 apply to the most commonly used types of cables, optical cables, wires and cords insulation and protection
Shell material.
4 Type tests and other tests
Test methods described in this section is first used as a type test. Some pilot projects of the type of tests and test regular
(Such as routine test) conditions are fundamentally different, this section has been pointed out these differences.
5 Pretreatment
Storage for at least 16h before the test should be carried out in all insulation and sheathing materials or curing (or crosslinking) after.
6 temperature test
The test shall be carried out at a temperature of about cable product standards.
7 intermediate value
When the test data obtained proper number in ascending or descending order, if the number of valid data is odd, the median is positive
A middle value; if even, the median is the average of the middle two values.
