3.1 The terms and definitions of this standard shall be interpreted in accordance with GE 2900. 3.2 Tests
a. Type test ypets1s code T
Type test is a test performed by the manufacturer before supplying a certain type of cable specified in the cable standard. The characteristic of type test is that it is generally not repeated after being done once, but when the materials, structure and main process used in the cable are changed and the performance of the cable specification is affected, the test must be repeated; or when there are other provisions in the product standard, such as regular testing, the test should also be repeated as specified. b. Sampling test sampletetts code s
Sampling test is a test performed by the manufacturer by taking complete cable environments according to the manufacturing batch or specified rate and cutting samples or components from them. c. Routine test routine tests Code R Creative test is a test conducted by the manufacturer on all finished wires and cables. Approved by the State Machinery Industry Commission on May 23, 1988 and implemented on January 1, 1989
