Detail of GB/T 17738.1-2013

Introduction of GB/T 17738.1-2013

1 Scope This International Standard specifies requirements for radio frequency coaxial cable assemblies (composed of cables and connectors) operating in the transverse electromagnetic mode (TEM) and establishes general requirements for testing the electrical, mechanical and environmental properties of radio frequency coaxial cable assemblies. Additional requirements relating to specific families of cable assemblies are given in the relevant sectional specifications. Note 1: The design of the cables and connectors used shall preferably conform to the applicable parts of IEC 61196 and IEC 61169 respectively. Note 2: This specification does not include tests which are normally performed on the cables and connectors separately. These tests are described in applicable parts of IEC 61196-1 and IEC 61169-1 respectively. Note 3: Wherever possible, cables and connectors used in cable assemblies, even if they are not described in the IEC 61196 or IEC 61169 series are tested separately according to the test methods given in the relevant generic specification. Note 4: Where additional protection is applied to a cable assembly, the mechanical and environmental tests described in this standard are applicable. 2 Normative References The following documents are indispensable for application of this Standard. For dated normative references, only the dated editions are applicable to this document.
