Test Method for Determining Blocking Resistance and Associated Characteristics of Automotive Trim Materials

2012-10-15
CURRENT
J912_201210
This test method is designed to indicate the degree of surface tackiness, color transfer, loss of embossment, and surface marring when two trim materials are placed face to face under specific conditions of time, temperature, and pressure. These specific conditions are not dictated in this test procedure but will be found in the material standards which govern each type of trim material to be tested.

Test for Chip Resistance of Surface Coatings

2012-10-23
CURRENT
J400_201210
This SAE Recommended Practice covers a laboratory procedure for testing and evaluating the resistance of surface coating to chipping by gravel impact. The test is designed to reproduce the effect of gravel or other media striking exposed paint or coated surfaces of an automobile and has been correlated with actual field results. The specific intent of the test is to evaluate organic surface coatings or systems on flat test panels; however, It may be possible to extend this type of testing to finished parts or other types of materials such as anodized aluminum or plated plastics if the results are interpreted with respect to the limitations and intent implied by the original testing procedures and rating system. This document may involve hazardous materials, operations, and equipment. This document does not purport to address all of the safety problems associated with its use.
