Description
Product Introduction:
This testing machine is primarily designed to comply with the national standards GB/T 19766 “Natural Marble Building Panels” and GB/T 9966.4 “Test Methods for Natural Facing Stone—Part 4: Test Method for Abrasion Resistance,” as well as the U.S. standard ASTM C241‑90 “Standard Test Method for Abrasion Resistance of Stone Subjected to Foot Traffic.” It meets the requirements set forth in these standards for conducting abrasion‑resistance or wear‑resistance tests on natural granite, natural marble, limestone, sandstone, slate, and other architectural decorative materials (such as engineered stone and microcrystalline glass). This specialized equipment is used to evaluate the abrasion resistance or wear resistance of building and decorative materials, and it is an essential instrument for stone quality‑inspection agencies at all levels, building‑material research laboratories, and large‑scale stone enterprises.
