European foreword
This document (prEN 3155-045:2023) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 3155-045:2019.
EN 3155-045:2019:
— normative references updated;
— figure of colour identification bands corrected in Table 2;
— document editorially revised.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
1 Scope
This document specifies the required characteristics, 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 is used together with EN 3155-001.
The associated male contact is specified in EN 3155-044.
Double crimping contact has a barrel which is designed to crimp conductor and jacket of cable in two
locations, one on the conductor and the other on the jacket. This way it protects the conductor from
mechanical strengths.
