Significance and Use
5.1 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 compares the porosity of a film drawn down at room temperature to another film drawn down and cured at low temperature.
5.2 This practice provides no absolute information, rather ranking only of the selected series of paints.
5.3 This practice can provide a pass-fail situation if known acceptable and unacceptable paints are included in the test.
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.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
