They are specified as a 260 “C class instead
8、of a 200 “C class as detailed in the MIL standard. 1 Scope This standard specifies the required characteristics and tests applicable to female contacts 005, type A, crimp, class T, used in elements of connection according to EN 31 55-002. It shall be used together with EN 31 55-001. The associated m
9、ale contacts are defined in EN 31 55-004. 2 Normative re fe re n ces This European Standard incorporates by dated or undated reference provisions from other publications.
