After enquiries and votes carried out in accordance with the rules of this Association, this Sta
14、ndard has re-ceived the approval of the National Associations and the Official Services of the member countries of ASD, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the late
15、st by September 2007, and conflicting national standards shall be with-drawn at the latest by September 2007. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or
16、all such patent rights.

EN 3155-004:20074 0 Introduction The contacts defined by this standard are derived from those of MIL-C-39029/4 and, in
18、termateable 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 element
19、s 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.
