Scope

This standard specifies the required characteristics and tests applicable to female triaxial contacts 043,
size 08, type D, solder, class P, used in elements of connection according to EN 3155-002.
The associated male contacts are defined in EN 3155-042.
These contacts are derived from and are interchangeable with those of standard AS 39029/95.
