　　 hardness is material pressure deformation degree or resistant can force types material 理 degree amount methods. hardness can separation versus for hardness and for hardness. for hardness generally in 科学界 use, production in very less use to. usually use hardness system is versus for hardness, commonly used has below/following types methods: 肖氏（也叫 Shore, 邵尔, 英文SHORE), 洛氏, 布氏三 types. Shore generally used for type material upper.

　　 Shore hardness testing methods: use Shore hardness 计插入 by material, table/sheet upper through elastic and 一 刺针 versus 连, use 针刺入 by material surface, table/sheet upper 显示 数 value is hardness value.

　　洛氏 hardness testing methods: use experiment/testing can in by material upper upper 痕迹时 hardness table/sheet upper 显示 数 value is hardness value. hardness is hardness 十倍, generally used for metal material upper.

　　因 testing methods different Shore hardness and hardness, 布氏 hardness 没 has methods, use hardness hard 橡胶, data is: Shore hardness 90 洛氏 hardness 27 .

　　 Shore hardness is use Shore hardness 计测出 value 读数, it mono is “ degree ”, its methods separation A, D两 types, separation table/sheet different hardness scope/range, 90 degree below/following use Shore A hardness testing, 并 出 data, 90 degree and above use Shore D hardness testing 并 出 data, therefore, generally for/regarding 一 橡胶 or plastics products, in testing 时候, testing can according to experience testing front 预判, from 而决定 use Shore A hardness also is use Shore D hardness 计 进行 testing. generally elastic property comparison large or 者说偏 soft products, testing can 直接判断 use Shore A hardness testing, 如: tool type water bottle, TPU TPR plastics film bag and other products. 而手感 basic what elastic property or 者说偏 hard can use Shore D hardness 计进行 testing, 如: PC ABS PP and other products. if degree is Shore Axx, hardness versus for high, if is Shore Dxx说明 its hardness versus for relatively high.

　　补充:

　　 Shore mono 位不够 comprehensive :

　　1.A type mono table/sheet is :HA

　　2.D type mono table/sheet is :HD
