WTB-B Bohme abrasion tester

1.introductions

It  is mainly to test the wear resistance of natural stone and other  building decoration materials (such as artificial stone, glass-ceramic,  etc.). This machine is designed and manufactured according to the  requirements of test method B of EN 14157:2004 "Natural Stone Abrasion  Test". This machine has been carefully designed and has the  characteristics of stable speed, accurate load, and beautiful  appearance.

2. relative test method

EN 14157  natural stone test methods:determination of the abrasion resistance
