3 Terms and Definitions
The following terms and definitions as well as those defined in GB/T 2900.10-2001 are applicable to this Part.
3.1
Type tests
T
Type tests are done on a kind of cables specified in this Part according to the general commercial principles before delivery of goods in order to prove the cables have satisfactory performance and can meet the specified operation requirements. The essence of type tests is that once these tests are done, they will not be repeated. However, the type tests must be repeated if the cable materials or the design change may influence the cable performance.
