Introduction

Note: Nothing in this standard supercedes applicable laws and regulations.

Note: In the event of conflict between the English and domestic language, the English language shall take precedence.

Purpose. This specification provides the acceptance criteria for product joined by self-piercing rivets (SPR).

Applicability. Self-piercing rivets are rivets that do not require a prepunched hole but are pushed through the stack-up by a punch and are flared by a die to join two or more layers together. The criteria established in this specification become mandatory when referenced on a product drawing or Statement of Requirements. Deviations from any acceptance criteria provided in this standard shall be identified on the product drawing or in the Statement of Requirements.

Remarks. For any clarification of this specification or for editorial comments, e-mail the GM Weld Council at weld.council@gm.com.

Usage. Self-piercing riveted joints are considered satisfactory when they meet the expected design service loads and satisfy functional performance requirements. The evaluation criteria contained in this document have been established as a basis for the manufacturing acceptance of self-piercing riveted joints and are the same for all applications using self-piercing rivets regardless of service load. Furthermore, riveted joints identified as discrepant often retain a percentage of their mechanical properties and may contribute to the integrity of the product.
