During the tests using these gauges, shutters shall be held open.
The metallic parts of gauges A, B and C are made of hard corrosion-resistant metal (e.g. stainless steel).
An electrical indicator with a voltage not less than 40V and not more than 50 V is used to show contact.
The gauge A shall be introduced through the entry holes of the socket-contactassembly in every possible position until the plane XX is fully in contact with the engagement face.
