用刀口宽约10mm~12mm的百格刀在测试样本表面划10×10(100个) 的正方形小网格,以1mm~1.2mm为间隔,
每一条划线应深及**的底层;? 用毛刷将测试区域的碎片刷干净;? 用P-99胶带或等同效力的胶纸
牢牢粘住被测试的小网格,并用橡皮擦用力擦拭胶带以加大胶带与被测区域的接触面积及力度;? 用手
抓住胶带一端,在垂直方向(90°)迅速扯下胶纸,同一位置进行2次相同试验。结果判定: 手机客户要
求附着力≥4B为合格。实验等级:? ISO等级:0 =ASTM等级:5B (切口边缘**光滑,格子边缘没
有任何剥落)? ISO等级:1 =ASTM等级:4B (在切口的相交处有小片剥落,划格区内实际破损≤5%
)? ISO等级:2 =ASTM等级:3B (切口的边缘和/或相交处有被剥落,其面积大于5%~15% )?
ISO等级:3 =ASTM等级:2B (沿切口边缘有部分剥落或整大片剥落,或部分格子被整片剥落。剥落的面
积超过15%~35% )? ISO等级:4 =ASTM等级:1B (切口边缘大片剥落/或者一些方格部分部分或**
部剥落,其面积大于划格区的35%~65% )? ISO等级:5 =ASTM等级:0B(在划线的边缘及交叉点处
有成片的**脱落,且脱落总面积大于65%)。 长期代理美国IPG测试胶带LA26。
