4.4.1 General
When dissimilar metals are in close contact, adequate protection against corrosion shall be used for the
electromotive force of the cell not to exceed 0,25 V (see EN 3197).
4.4.2 Housing
The material of the housings for the connectors and fittings may be either aluminium alloy, passivated
stainless steel or composite. Aluminium alloy and composite shall be plated as defined by the class
(composite coupling rings and Hex nut may be unplated) (see EN 3645-002).
4.4.3 Contacts
Unless otherwise specified, the non-removable electrical contacts shall be in copper alloy.
They shall be gold-plated on an appropriate undercoat. Selective protection is authorized provided that
it is sufficient to ensure that the specified performance is achieved.
Measurement of the thickness of the protective plating shall be effected in accordance with ISO 4524-1.
For removable electrical contacts, see EN 3645-002.
For optical contacts, see EN 4869-101, EN 4869-102, EN 4869-103 and EN 4869-104.
