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.

Note: The words must, shall, or will as used in this document means a mandatory requirement.

Note: In the event of conflicts between the content/intent of this document and a certified laboratory version, this and only this document shall take precedence. Discipline regarding this test and its execution will be maintained and enforced if necessary, with removal of certification if violations occur.

Note: Specifics as to what is considered a GMW3155 test, are listed in Appendix A, A4.

Note: No one involved in GMW3155 testing is to make judgments or interpretations as to content/intent of this document and take independent action as a result. Any and all procedural issues (including deviations) are to be immediately brought to the timely attention of the document sponsor and the GM Global Sealing Technical Specialist before the event is reached. Our intent is to drive continuous improvement of document content and not risk voiding a test, due to unauthorized deviations. Any tested procedural step or content conducted in a test (without one (1) time approval) and is not covered in the latest written version of GMW3155 [including Criteria for Thermal Cycling Test for Life Assessment of Powertrain Sealing Systems (GMW3155)], is prohibited.

Purpose.

This test is used to predict the life of powertrain sealing as it applies to the intended system design. The system includes the gasket, fasteners, structural interfaces, and circulating media.

This test is used on components and assemblies (up to entire engines and transmissions) to identify and eliminate marginal seal designs and/or materials. Design has a significant influence on test results. Production released or production intent parts shall be used.
