GB/T 23988-2009 《Determination for abrasion resistance of - Coatings by falling abrasive》 Related products

The GB/T 23988-2009 standard specifies the determination of abrasion resistance of single or multi-layer films of Paints, varnish and related products by shakeout method. This method uses abrasive to fall on coatings and evaluates abrasion resistance by measuring the amount of abrasive required per unit film thickness. The standard describes the test equipment, material requirements, calibrating procedures, and operating procedures, including the specification of the standard sand and the calibrating of the outflow rate. The test is carried out under specific environment conditions and details the preparation of the sample, the measurement of the coating thickness, and the calculation of the abrasion resistance. The report shall include the standard number, test results and any deviation from the method.
