One Product Description: This machine tests the abrasion resistance of outer layers, linings, substrates, and similar fabrics of textiles, shoes, and similar materials. Four test pieces can be tested simultaneously. During the test, the friction hammer repeatedly rubs the test piece in a variable direction to measure its wear characteristics under a specified number of friction cycles. There are two different weights available for testing. According to the standard: compliant Standards、GB/T19089、ISO12945-2、ISO12947-1、ASTM D4966、ASTM D4970、IWS TM196,112、FZ/T20020、JIS L1096、GB/T4802.2 Waiting for standard requirements.
