Description / Abstract: 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.

Purpose. Coated exterior parts are exposed to a variety of environmental conditions. This procedure simulates the thermal shock that an exterior part would experience when a vehicle is cleaned on a cold winter day. Temperature extremes are used to ensure durability of the materials through "worst case" conditions and accelerate the onset of failure in a single test cycle. The purpose of this standard is to determine the resistance to coating adhesion loss of coated surfaces of aluminum, plastic, steel, and other substrates when subjected to a wet steam blast similar to that produced by vehicle wash equipment.

Applicability. Painted exterior components of vehicle.
