Description / Abstract:
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. This standard describes an accelerated
corrosion test that can be combined with mechanical, electrical,
and/or pneumatic inputs with environmental (chemical and thermal)
inputs to produce realistic vehicle part or system wear and aging.
This test is designed for corrosion replication of functional
incidents and where galvanic corrosion mechanisms are
present.
Foreword. This is a cyclic environmental test,
which exposes test items to periodic wetting with a salt/mud
solution followed by drying all at an elevated temperature. If
requested, forces or other dynamic inputs should be applied in a
realistic manner consistent with the function of the item under
test. The test requestor must define the test duration and the
required component loading based on anticipated failure mechanisms
and acceleration rates.
Applicability. This procedure is applicable to
passenger car and truck components or subassemblies. This test has
shown good test-to-field correlation of accelerated galvanic
corrosion with dynamic inputs.
