【国外标准】 Standard Test Method for Abrasion Resistance of Pipeline Coatings

5.1 This procedure defines a test method for comparing the relative resistance of pipeline coatings to abrasion.5.2 Abrasion resistance may be used to specify optimum coating thickness of candidate materials both in development and research work to study new coating systems or methods and in quality control.1.1 This test method of accelerated test is a procedure for determining the relative resistance of steel pipeline coatings to abrasion by a slurry of coarse abrasive and water. The method is intended to apply to the testing of all types of electrical insulating pipeline coatings and tapes, including thermoplastics, thermoset, and bituminous materials.1.2 Pipeline coatings are not normally subjected to the type of abrasion herein specified.1.3 Metallic protective coatings such as zinc may be compared visually, but do not meet the electrical requirements of this test method.1.4 The values stated in SI units to three significant decimals are to be regarded as the standard. The values given in parentheses are for information only.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
