1.1本规程规定了实验室程序，用于评估乳胶漆在低温下形成无可见缺陷的均匀膜的能力。 1.2以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3本标准无意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====== 涂料配方制定者可以使用该实践来确定给定涂料是否能够在低温下形成薄膜。本规程可用于确定形成良好薄膜所需的凝聚溶剂水平。试验方法D 3793 比较在室温下拉下的薄膜与在低温下拉下并固化的另一薄膜的孔隙率。 这种做法没有提供绝对信息，而只是对选定系列的油漆进行排名。 如果试验中包括已知可接受和不可接受的油漆，则本规程可以提供合格-不合格情况。

1.1 This practice specifies a laboratory procedure for evaluating the ability of a latex paint to form a uniform film free of visible defects at low temperatures. 1.2 The values stated in SI units 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 ====== This practice can be used by paint formulators to determine if a given paint has the ability to form a film at low temperatures. This practice can be used as an aid for determining coalescing solvent level required to form a good film. Test Method D 3793 compares the porosity of a film drawn down at room temperature to another film drawn down and cured at low temperature. This practice provides no absolute information, rather ranking only of the selected series of paints. This practice can provide a pass-fail situation if known acceptable and unacceptable paints are included in the test.
