FCA LP-463PB-64-01

Why is this test used?

FCA LP-463PB-64-01 Thermal Shock Procedure for Organic Coating Adhesion Test  is a method used to evaluate the resistance of organic coatings over steel, aluminum, plastic, or other substrates when subjected to rapid change in temperature and high pressure spraying.  This test is used to simulate the conditions a vehicle may experience during manual car wash spraying operations.

Equipment Required

This test utilizes a specially designed steam generator capable of providing a consistent flow rate, temperature, and pressure as specified in the test standard.  Nozzle size, and distance from the test specimen is also specified.  Assured Testing Services has a fully automated steam generation chamber that provides consistent, safe high pressure steam testing.

How is the test performed?

To perform the FCA thermal shock procedure, samples are prepared with an X-scribe, and then pre-conditioned with an immersion and freezer step.  Once the samples have been pre-conditioned as specified in the standard, they are subjected to a steam blast directed at the scribe.  After exposure, the scribe is evaluated for adhesive performance is rated and any other visual changes are noted.
