17、ors defined by EN 4644-001. The contact #22 defined by this standard are derived from those of SAE AS 39029-12 and are intermateable with those of SAE AS 39029-11. 1 Scope This European Standard specifies the required characteristics, tests and tooling applicable to female contacts size 22, 20, 16,
18、12, 8 and 5, type A, crimp, class R, used in elements of connection according to EN 3155-002. It should be used together with EN 3155-001. The associated male contacts are defined in EN 3155-076. 2 Normative references The following referenced documents are indispensable for the application of this
