意义和目的
5.1 干漆经常与自身接触, 尤其是在门窗领域, and can sometimes stick to itself (block) depending on its hardness, 压力, 温度, humidity and length of time the surface has been in contact. This rigorous test method can be used to subjectively compare and evaluate the adhesion resistance of paints.

范围
1.1 This test method covers an accelerated procedure for assessing the face-to-face adhesion resistance of coatings for trade sales. This should not be confused with anti-adhesion test method D3003, which involves blocking of industrial coatings on metal substrates, nor with test method D2793, which specifically deals with wood product finishes and reports results on a satisfactory or unsatisfactory basis, rather than by the degree of blocking tendency as in this test method.

1.2 Values expressed in SI units of measurement shall be considered as standards. 括号内的数值仅供参考.

1.3 本标准并非旨在解决所有安全问题, 如果有的话, 与其使用相关. 本标准的使用者有责任建立适当的安全和健康实践，并在使用前确定监管限制的适用性.
