They are specified as a 260 “C class instead of a 200 “C class as detailed in the MIL standard. 1 Scope Th

8、is standard specifies the required characteristics, tests and tooling applicable to male electrical contacts 004, type A, crimp, class T, used in elements of connection according to EN 3155-002. It shall be used together with EN 31 55-001. The associated female contacts are defined in EN 31 55-005.
