W.bzsoso: comGB 9333.1—88
The characteristic of type test is that it is generally not repeated after being done once, but when the materials, structures and main processes used in wires and cables have changed and affect the performance of wire relays, the test must be repeated; or when there are other provisions in the product standards, such as regular testing, the test should also be repeated according to the provisions.
b. Sampling test code sample tests
Axial sample test is a test conducted by taking complete wires and cables according to the manufacturing batch or specified degree and cutting samples or components from them.
g Routine test code Rroutine test
Routine test is a test conducted by the manufacturer on all finished wires and cables. 3.3 Separator
A thin layer of insulation between the conductor and the insulation or between the insulation and the sheath or armor to prevent the positive components from affecting each other. 3.4 Armor
A sheath made of metal wire or metal tape by shrinking or wrapping, used to protect the cable from external mechanical influences. 3.5 Dimensional value. Nominal value
A suitable approximate value used to specify or identify a component, device or equipment. In this standard, it is used as a dimensional value. The nominal value is usually combined with the standard tolerance and must be issued by the manufacturer to avoid errors. b. Median value
The test data that should be obtained should be arranged in increasing or decreasing order. When the number of valid data is an odd number, the middle value is the middle value. If it is an even number, the arithmetic mean of the two middle values is the middle value. t. Approximate value Bpproximate value

Counting starts from the center layer of the cable or the center layer of the unit to the outer layer, and the counting direction is clockwise. 9.10.2 Cable identification
Should comply with GB3995,3, and the marking content shall be the name and trademark of the manufacturer, certification mark, and model. 9. 11 Special performance
If required, it shall be specified in the relevant subsequent standards. 10 Variable length
10.1 The delivery length of the cable shall not be less than 100m. Short sections of not less than 20m are allowed to be delivered, but their quantity shall not exceed 10% of the total delivery length.
10.2 Any length of cable may be delivered according to the agreement between the two parties. 10.3 The length shall be measured with a meter, and the length error shall not exceed ±0.5%. 11 Test and acceptance
11. 1 The product shall be inspected and qualified by the technical inspection department of the manufacturer before it can be shipped out of the factory, and the shipped product shall be accompanied by a quality inspection certificate. 11.2 The product shall be tested in accordance with the following provisions:
a: Type test items - all performance items specified in the standard. Stone. Sampling test items: conductor structure, insulation, sheath and cable size, hot extension of EPDM insulation and cross-linked polyethylene insulation, low temperature performance of polyvinyl chloride insulation and sheath, chemical test of conductor coating. c. Routine test items: conductor DC resistance, voltage test, insulation resistance at room temperature. 11.3 Frequency of sample test
2. Structural dimension inspection: If required by the user, it should be carried out on one manufactured length cable of each manufacturing batch of the same model and specification, but it should be limited to no more than 10% of the total number of cables in the contract. b: Physical property test: Samples are taken from the cables delivered according to the contract. When the total length of the cables in the contract exceeds 2km, the user and the manufacturer can determine it through agreement based on the provisions of Table 18. C. If the first sampling test fails, another double number of samples should be taken from the delivery batch for the unqualified items for the second test. If it still fails, the batch of cables is considered unqualified. Table 18
