Automotive Environmental Cycles

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 procedure documents various environmental cycles and aging conditions that may be performed prior to testing or as a complete test. This specification does not include standard conditions for testing or preconditioning prior to testing. Those requirements may either be found in the material specification or in GMW3221.
Applicability. Refer to Table 1 for applicability.
Note: Some of the test cycles in this specification are best used as a quality control test and are not meant to validate potential field performance. See the platform materials engineer for additional details.
Remarks. This procedure documents several cycles that have been globally agreed upon for material specifications. Only those cycles shall be selected to create requirements for GMW material specifications. The globally agreed upon cycles for material specifications are: Cycles M, Q, R, S, T, U, V and W. For test cycle uses, see 4.1.2.
Exposure environments, cycle durations, and the applicable tolerances are generally defined in the sections and tables that follow. However, prior to the initiation of testing these variables should be confirmed by reviewing the applicable material specification, test procedure, or by verifying the test cycle with the requesting engineer.
