3.1 The terms in this standard are explained in GE 2900. 3.2 RF conductor: RF cable conductor consists of an inner conductor and an outer conductor, both of which are used to connect the RF source and effectively transmit signals. 3.3 Solid dielectric: The space between the inner and outer conductors is filled with a dense dielectric, which can be made of a single material or a combination; the latter is made of two different materials concentrically bonded together. 3.4 Test
. Type test Code T Type test is a test conducted by the manufacturer before establishing a cable specified in the standard. The characteristic of type test is that it is generally not repeated after being done once. However, when the materials, structure and main processes used in the cable are changed, which affects the performance of the cable relay, the test must be repeated; or when otherwise specified in the product specification, such as regular testing, the test should also be repeated as required. b. Sampling test code s Sampling test is a test performed by the manufacturer on components of the whole cable sampled from the batch or specified rate and cut out from them.
