意义和目的
5.1 The tensile properties determined by this method are valuable for studying the behavior of coatings subjected to environmental stresses, such as those arising from aging and weathering. (See Ref. (1-10).) 四

5.2 Tensile properties may vary depending on specimen thickness, preparation method, gauge length, load application rate, tensile tester response and type of fixture used. 所以, these factors need to be carefully controlled when precise comparative results are required.
