EN 3155-004:20074 0 Introduction The contacts defined by this standard are derived from those of MIL-C-39029/4 and, int
18、ermateable with those of MIL-C-39029/5. They are specified as a 260 C class instead of a 200 C class as detailed in the MIL stan-dard. 1 Scope This standard specifies the required characteristics, tests and tooling applicable to male electrical con-tacts 004, type A, crimp, class T, used in elements
19、 of connection according to EN 3155-002. It shall be used together with EN 3155-001. The associated female contacts are defined in EN 3155-005. 2 Normative references The following referenced documents are indispensable for the application of this document.
