ASTM20345 slip resistance tester for safety shoes test

Application:

used to test the anti slip performance of the rolling or bottom to bottom working state;

Standards:

GB / T 28287-2012, en 13287-2012, ASTM f2913-2011 (ASTM f1677-2005), SATRA tm144 EN 15020344, EN 15020345；

Principle: according to different media (not referring to weak board, ceramic tile or specified), add specified section check. Set the specified times and speed of alum wiping to measure the bottom to bottom friction coefficient, so as to determine the sliding resistance of each sub;

Test item: 

follow xiaowat forward (Forward heel slip)

Back in front of you (Backward forepart slip)

Forward five to Wan Zhen (Forward flat slip)
