Do you know how many standards for Martindale abrasion tester? which is used to test different material abrasion and pilling situation. The principle is testing sample with continues different direction abrasion and friction under certain pressure. Then compare tested sample with original standard configuration for envaluating its abrasion status. Here you may wonder what kinds of standard that this tester may have, So QINSUN will explain those Martindale abrasion testing standards for you:
1、ASTM D4970 ISO 12945.2、
2、GB/T 4802.2/13775/21196.1/21196.2
3、ASTM D4966
4、ISO 12947 FZ/T 20020 BS 3424-24/5690
5、ISO 12947.1/12947.2 M&S P17/P19/P19C NEXT 18/18a/18b
6、ISO 5470-2 IWTO-40
7、JIS L1096 8.17.5 Method E Woolmark TM 112/196 BS EN 388/530/13770
8、ISO 20344
For reminding, QINSUN would like to suggest user pay attention for Martindale tester parameters:
1.Counting range：0～999999 times；
2.Position numbers：9 heads；
3.Pressurized material mass： a.Holder：200±1g b.Cloth sample weight：395±2g c.Furniture decoration sample weight：594±2g d.Stainless steel disc：260±1g
4.Range of motion：Horizontal：60.5±0.5mm，Vertical：24±0.5mm；
5.Effective friction diameter of magic block： A type 200g（1.96N）friction head（9kPa）￠28.8 －0.084mm B type 155g（1.52N）friction head（12kPa）￠90 －0.10mm
6.Quality of loading hammer：2385±10g；
7.Relative speed of gripper and grinding table：20-70r/min（adjustment）
