GMW3172 Testing For Electrical/Electronic Components – Environmental/Durability

Accredited testing laboratory

Overview of GMW3172

General Motors (GM) GMW3172 standard applies to electrical/electronic (E/E) components for passenger or commercial vehicles and trucks. The standard describes the environmental and durability tests for E/E components based on mounting location.

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

GMW3172 Testing is applied in 4 testing phases:

  • Analysis: The earliest of the phases involves component design and improvement. This phase should be use to design reliability and robustness into the component.
  • Development: These actives are performed on the first samples to provide a qualitative evaluation of the samples and improve the initial design.
  • Design Validation (DV): This phase is meant to provide a quantitative and qualitative verification of the component design. It should include environmental, durability and reliability actives on production intent designs and materials.
  • Product Validation (PV): This phase is meant to provide a quantitative and qualitative verification of environmental, durability and reliability actives on samples made on production tooling and manufacturing process.

Testing for the phase are completed in multiple test legs that encompass initial sample inspection and functional checks, electrical and EMC testing, environmental testing, corrosion, vibration and other mechanical testing. No matter which phase or test leg your component is in, TÜV SÜD can support it!
