意义和目的
5.1 The tensile properties measured by this method are valuable for studying the behaviour of coatings under environmental stresses such as those arising from ageing and weathering. (See references (1-10).) 4

5.2 Tensile properties may vary with specimen thickness, 制备方法, spacing, rate of load application, response of tensile tester and type of fixture used. 所以, these factors need to be carefully controlled if precise comparative results are required.
