1.1 本试验方法涵盖了评估涂料面对面抗堵塞性的加速程序。不要将其与阻塞电阻测试方法混淆 D3003 ，这与金属基材上工业涂层的堵塞有关，也与试验方法无关 D2793 这与木制品饰面有关，并在满意或不满意的基础上报告结果，而不是本试验方法中的堵塞倾向程度。 1.2 以国际单位制计量单位表示的数值应视为标准。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 5.1 干漆通常会与自身接触，尤其是在门窗区域，并且根据其硬度、压力、温度、湿度和表面接触的时间长短，有时会粘附（积木）。这种严格的测试方法可用于比较和主观评价涂料的耐堵塞性。

1.1 This test method covers an accelerated procedure for evaluating the face-to-face blocking resistance of trades sales paints. This is not to be confused with blocking resistance Test Method D3003 , which is concerned with blocking of industrial coatings on metal substrates, nor with Test Method D2793 which is concerned specifically with wood product finishes and reports results on a satisfactory or not satisfactory basis, rather than by the degree of blocking tendency as in this test method. 1.2 The values stated in the SI units of measurement 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 5.1 Dry paint often comes in contact with itself especially in window and door areas and, depending on its hardness, the pressure, temperature, humidity, and duration of time the surfaces are in contact, sometimes sticks to itself (blocks). This stringent test method can be used to compare and rate subjectively the resistance of paints to blocking.
