GMW3172 specifies environmental/endurance requirements and analytical/development/validation (A/D/V) activities for electrical/electronic components used in a vehicle environment to ensure a lifetime of reliability.

GMW 3172 Test Procedures

Analysis, the earliest of the stages, includes component design and improvement. This phase should be used to design reliability and robustness into the component.

Development is carried out on these assets to provide a qualitative evaluation of the samples and to improve the initial design.

Design Verification (DV), this phase aims to provide quantitative and qualitative verification of component design. It should include environmental, durability and reliability assets on designs and materials for production purposes.

Product Validation (PV), this phase aims to provide quantitative and qualitative verification of environmental, durability and reliability assets on production tools and samples made during the production process.


Intertek, automotive environmental and EMC laboratories are accredited to ISO 17020 and can help ensure your automotive electrical/electronic component, subassembly or systems meet global OEM and industry standards.

Testing for stages is completed in multiple test legs covering initial sample inspection and functional checks, electrical and EMC testing, environmental testing, corrosion, vibration and other mechanical testing. No matter what stage or test leg your component is in, EUROLAB fulfills its continuity.
