1 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: Requirements stated in any applicable Component Technical Specification (CTS), Subsystem Technical

Specification (SSTS), and/or other relevant General Motors requirements document shall take precedence over

GMW3172.

1.1 Purpose. This 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.

1.2 Applicability. This standard specifies Environmental/Durability requirements and

Analysis/Development/Validation (A/D/V) activities for E/E components that are used in a vehicle environment

to ensure reliability over a life time.
