After enquiries and votes carri
7、ed out in accordance with the rules of this Association, this Standard has received the approval of the National Associations and the Official Services of the member countries of AECMA, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either
8、by publication of an identical text or by endorsement, at the latest by November 2006, and conflicting national standards shall be withdrawn at the latest by November 2006. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/o
9、r CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,

EN 3155-045:2006 4 1 Scope This standard specifies the required ch
11、aracteristics, tests and tooling applicable to female electrical contacts 045, type A, double crimping, class T, used in elements of connection according to EN 3155-002. It shall be used together with EN 3155-001. The associated male contact is defined in EN 3155-044. Double crimping contact has a b
12、arrel which is design to crimp conductor and jacket of cable in two locations, one on the conductor and the other on the jacket. This way protect the conductor from mechanical strengths. 2 Normative references The following referenced documents are indispensable for the application of this document.
