Overview:

This testing machine is mainly applicable to the national standard GB/T19766-2016 "Natural Marble Building Slabs" and the national standard GB/T9966.4-2020 "Test Methods for Natural Stone - Part 4: Determination of Abrasion Resistance", as well as the American standard ASTM C241-90 "Standard Test Method for Abrasion Resistance of Stone Subjected to Foot Traffic". It meets the requirements of these standards for abrasion resistance or wear resistance tests on natural granite, marble, limestone, sandstone, slate, and other architectural decorative materials (such as artificial stone, glass-ceramic, etc.). It is a dedicated testing equipment for checking the abrasion or wear resistance of architectural decorative materials, and an essential device for stone quality inspection agencies, building materials research laboratories, and large stone enterprises.

Features:
