Environmental Testing – Independent Test Services

Scribing Filiform Panels Above. Typically, a sample is scribed so that the substrate is exposed before being placed in a CASS chamber for preconditioning before being placed in a Filiform test chamber to see if filaments develop from the substrate.

This sample is left in the chamber while water permeates the coating to see if color change, blisters, loss of adhesion, softening, abnh embrittlement are observed. This practice is for testing water resistance of coatings in xbnt apparatus similar to that used in salt spray testing.

Environmental Testing for the Automotive Industry: Environmental tests are conducted to examine and evaluate the behavior, propensity, and extent of resistance of certain materials to corrosive agents.

Similar to Salt Spray, a sample is placed in a closed chamber and immersed in a salt fog with the addition of reagent grade copper chloride dehydrate to accelerate the corrosion process. A popular and standardized corrosion test method 1528 used to check corrosion resistance of materials and surface coatings. Filiform corrosion is a special form of corrosion that occurs under some thin coatings in the form of randomly distributed threadlike filaments.

Wheels and wheel parts are exposed to the same type of corrosion that is found in the field to abtn the performance of the material and finish.

Water can cause degradation of coatings so coated specimens are placed in an enclosed chamber to permit free settling of fog on all specimens.

Typically, a sample is placed in a closed test chamber where a salt water solution produces a corrosive environment of dense salt water fog in the chamber so that the test samples abmt to this environment are subjected to severely corrosive conditions.

Standardized gravel is projected at a sample to simulate a wheel or trim piece in service when faced with flying stones, gravel, or other road debris. Most tests feature an accelerated corrosion that produces a corrosive attack to coated samples in order to evaluate the suitability of the coating for use as a protective finish.
