1.1 This accelerated test method is a procedure to determine the relative wear resistance of steel pipe coating to coarse abrasive and water slurry. The method is applicable to the testing of all types of electrical insulating pipe coatings and tapes, including thermoplastics, thermoset, and asphalt materials.

1.2 Pipe coatings are generally not subject to the type of wear specified in this article.
