1.1 This test method covers a laboratory procedure for determining the lap shear strength of sealants. It also provides information on the adhesive bond of the sealants to the tested substrates. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 The subcommittee with jurisdiction of this standard is not aware of any similar or equivalent ISO standard. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
1、剪切强度:胶接头在单位面积上能承受平行于胶接面的最大负荷。根据受力方式分为:拉伸剪切、压缩剪切、扭转剪切和弯曲剪切。剪切强度的测试方法: A、单搭接拉伸剪切强度测试方法:此法为最常用的铝片单面搭接方法,其标准尺寸:试片在测定时应不少于5对,取其算术平均值并观察试片的破坏特征 B、压缩剪切强度测试方法:该法用于厚的非金属板材的胶接强度测试。 ...
以下材料的常见力学性能1.胶黏剂:拉伸强度、断裂伸长率2.聚乙烯:拉伸强度、断裂伸长率3.防腐层整体:剥离强度、抗弯曲4.防腐材料补口(热收缩带):拉伸强度、断裂伸长率,耐热老化,搭接剪切强度(23℃,50℃,70℃),剥离强度,剪切强度。...
胶粘剂拉伸剪切强度是在平行于粘接面且在试样主轴方向上施加一拉伸力,测出的刚性材料单搭接粘接处的剪切应力。 按照标准要求制备试样:试样根据图2要求制备至少五个,粘接面长度为12.5mm±0.25mm。将试样对称的夹在NLW-20胶粘剂拉伸剪切试验机的夹具上,夹持处至距离zui近的粘接端的距离为50mm±1mm。夹具中可使用垫片,以保证作用力在粘接面内。...
NLW-20胶粘剂拉伸剪切试验机专业适用于各类胶粘剂进行粘接强度的拉伸、剪切、压剪、扯离试验。...
