GMW 14085 Mechanical Rivet Joining Acceptance Criteria and Repair Procedures

EUROLAB Laboratory provides accredited testing and conformity assessment services within the scope of GMW 14085 standard. This standard provides the acceptance criteria and repair procedure for circular mechanical rivets in automotive products for which GM is responsible for establishing or approving the product design.

GMW 14085 Mechanical Rivet Joining Acceptance Criteria and Repair Procedures

A rivet is a mechanical fastener that has the appearance of a metal pin, consisting of a head at one end and a cylindrical body (called a tail) at the other end.

During installation, the rivet is inserted into a drilled hole and the tail is turned upside down or bent so that it expands to approximately 1,5 times the original shaft diameter, holding the rivet in place.

Riveting can create lap or butt joints with a variety of different rivet configurations, including single, double and zig-zag formations.

Blind rivets have strength properties that can be measured in terms of shear and tensile strength. From time to time, rivets also undergo performance testing for other critical properties such as thrust force, breaking load and salt spray resistance.

The shear test involves inserting a rivet into two plates of the specified hardness and thickness and measuring the force required to cut the plates. The tensile test is basically the same except that it measures tensile strength. According to the standard, all blind rivets produced must meet this standard. These tests determine the strength of the rivet.
