GB/T 9966.4-2020 Test methods for natural stone—Part 4:Determination of abrasion resistance
Abstract
This part of GB/T 9966 specifies the instrumentation and equipment, test samples, test procedures, test results, and test reports for the abrasion resistance testing of natural stone. This part is applicable to the determination of the abrasion resistance of natural stone. The abrasive disc wear method (Method A) is suitable for material-related tests, such as rough stones and paving stones; the abrasive wheel grinding method (Method B) is suitable for product-related tests, such as composite boards and marble slabs with crystallized surfaces.
