BS EN 3155-004-2019 pdf free download.Aerospace series – Electrical contacts used in elements of connection Part 004: Contacts, electrical, male, type A, crimp, class T – Product standard
This European 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 3155-001.
The associated female contacts are defined in EN 3155-005.
The contacts defined by this standard are not applicable for connector EN 2997 classes KV, SV, KF and SF (defined in EN 2997-002).
