Classification of test types
(1) Type test (symbol T): According to general commercial principles, a test is conducted on a type of cable specified in the standard before supply to prove that the cable has good performance and can meet the specified usage requirements. The essence of type testing is that once these tests are conducted, there is no need to repeat them. If changing the cable material or design will affect the performance of the cable, it must be repeated
(2) Sampling test (symbol S): Conduct tests on finished cable samples or original parts taken from finished cables to prove that the finished cable product meets the design specifications (3) Routine test (symbol R): refers to the test that must be carried out before the finished cable leaves the factory. It should be carried out 100%
The inspection during the production process can be divided into
(1) Raw material inspection: also known as incoming inspection, which is the inspection of the raw materials used for wires and cables to confirm whether the raw materials meet the standard requirements.
(2) Inspection of semi-finished products: Inspection during the production process to confirm whether the semi-finished products produced meet the requirements (mainly based on the requirements of the enterprise)Function of testing report:
