Paints and varnishes - Test method for evaluation of adhesion of elastic adhesives on coatings by peel test, peel strength test and tensile lap-shear strength test with additional stress by condensation test or cataplasm storage (ISO 22970:2019) 色漆和清漆.用剥离试验、剥离强度试验和通过冷凝试验或巴布浆储存附加应力的拉伸搭接剪切强度试验评估涂层上弹性粘合剂附着力的试验方法(ISO 22970-2019)

本文件规定了三种测试剥离附着力、剥离强度和拉伸搭接剪切强度的方法,以评估涂层上弹性粘合剂的粘结以及失效类型、位置和结构。例如,汽车前照灯玻璃上的塑料覆盖物的测试方法是用塑料覆盖物,例如汽车覆盖物。气候暴露的两种方法 本文所述的样品是冷凝试验和巴布剂储存。 本文件未规定粘合剂和涂料的要求。 注:ISO 8510-2中描述了刚性车身结构胶粘剂的剥离强度试验(方法B)。EN 1465中描述了刚性车身结构胶粘剂的拉伸搭接剪切强度试验(方法C)。刚性车身结构粘合剂的测试通常在较小的接缝厚度上进行,即<1 mm。
This document specifies three methods for testing the peel adhesion, peel strength and tensile lap-shear strength in order to evaluate the adhesive bond as well as the type, location and structure of failures of elastic adhesives on coatings. These methods are used, for example, for testing the assembly with respect to the bond of panes or built-on parts, such as plastic covers, spoilers, instrument panel covers, headlights, with coatings for automobile construction. The two methods of climatic exposure of specimens described herein are the condensation test and cataplasm storage. This document does not specify requirements for adhesives and coatings. NOTE The peel strength test (method B) for rigid car body construction adhesives is described in ISO 8510‑2. The tensile lap-shear strength test (method C) for rigid car body construction adhesives is described in EN 1465. Testing of rigid car body construction adhesives is generally conducted on small joint thicknesses, i.e. <1 mm.
