Description / Abstract:
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 standard provides the manufacturing acceptance criteria for structural bonding in automotive products for which GM is responsible for establishing or approving product design. This standard does not apply to weld through, metal bonding, hem flange or anti-flutter (semi-structural) adhesives.
Applicability. This standard applies to any applications where a structural adhesive (9982247, 9982265, 9986130, 9986133, 9986223, 9986274 or 9985693) is used to bond automotive fiber reinforced plastic substrates. The criteria established in this standard become mandatory when referenced in product release information. Deviations from any adhesive criteria provided in this standard must be identified in product release information or an approved Product Quality Standard (PQS) document.
Usage. Structural bonds are considered satisfactory when they carry the intended service loads for a required period. Service loads on structures containing adhesive bonds are varied in both type and magnitude and cannot be addressed by this standard. Therefore, while the adhesive acceptance criteria of this standard are consistent with service loading requirements, they have been established specifically for use in process and product monitoring. Any attempted application of this document to other uses, such as post-crash quality assessment, may lead to an erroneous result or conclusion. Discrepant adhesive applications may still contribute to the integrity of the assembly by retaining a portion of their engineering properties.
Clarification. For clarification of this standard or editorial comments, email the GM Global Weld Council at: weld.council@gm.com.
Proposed changes to this standard must be presented to the Global Weld Council. To suggest a change to this standard, reference the "Procedure for Weld Standard Changes" on the Global Weld Council's web page.
