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.

1.1 Purpose/Material Description. This standard provides the acceptance criteria and repair procedures for

pumpable adhesive(s) for anti-flutter applications in automotive products for which GM is responsible for

establishing or approving product design.

1.2 Applicability. This standard applies to any application where an adhesive intended for use in the body shop

is used for bonding exterior automotive body panels for anti-flutter.

The criteria established in this standard become mandatory when referenced in product release information or

an approved Product Quality Standard (PQS) document. Deviations from any adhesive criteria provided in this

standard shall be identified in product release information or an approved PQS document.

1.3 Remarks. Structural bonds are considered satisfactory when they meet the performance requirements,

defined in the material specifications. Service loads on structures containing adhesive in a vehicle are varied in

both type and magnitude and cannot be addressed by this standard. Therefore, while the adhesive quality 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.

1.4 Clarification. For clarification of this standard or editorial comments, email the GM Weld Council at:

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

standard, reference the “Procedure for Weld Standard Changes” on the Weld Council’s web page.
