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

Proposed changes to this standard must be presented to the
Global Weld Council. To suggest a change to this standard,

Weld Council's web page.
