This standard applies to the test method standards for the manufacturing length of long-distance and urban communication cables. Under appropriate conditions, it can also be used as a reference in the corresponding tests on other communication cables or installed communication cables. The important electrical parameters of the communication cables tested by the test methods specified in this standard are necessary to ensure the transmission quality and reliability of the communication cable transmission system. Any test conditions not specified in the test method should be specified in the product standard when necessary. The communication cable test method standard is first used as a type test. Sampling tests and routine tests should also be adopted unless otherwise specified in the product standard.

2 Definition
2.1 Type test (code T) Type test is a test conducted by the manufacturer before supplying a certain type of cable according to the product standard. The characteristic of type test is one-time test. When the material, structure and main process of the cable are changed, which may affect the performance of the cable, the test must be repeated. Or when there are other provisions in the product standard, such as periodic test, etc., the test shall also be repeated according to the provisions.
2.2 Sampling test Sample test (code S) Sampling test is a test conducted by taking a complete cable from the manufacturing batch, or cutting or extracting a sample or element from it. 2.3 Routine test Routine test (code R) Routine test is a test conducted by the manufacturer on all finished cables. 3 General provisions
3.1 Unless otherwise specified, the test shall be carried out at ambient temperature. 3.2 In addition to the test methods specified in the communication cable test method standard, other electrical properties, such as insulation resistance, dielectric strength test (voltage test), and physical and mechanical properties test, shall adopt the relevant wire and cable test method standards. Supplementary provisions may be made when necessary. 3.3 The drawings of test instruments and equipment in the test method standard are schematic diagrams of an instrument that may be used in the test. Various test instruments and equipment must be calibrated regularly in accordance with regulations to maintain a good test state. National Bureau of Standards 1985-09-29 Issued
