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.
