Meaning and Purpose
The test method does not provide absolute information, but only ranks the selected paint series.

This test method can provide a pass-fail situation if the test contains known acceptable and unacceptable paint.

ASTM D 3793-2006 Low Temperature Polymerization of Latex Paint Films

Scope of
1.1 This test method consists of determining the comparative coalescence of a series of latex paints by measuring the porosity of films dried at standard and low temperatures. Porosity was assessed using a penetrating medium as shown in test method D 3258.

1.2 The texture of the film will affect the cleaning and the test results. A stain applied to a high shading paint does not reduce the reflectivity as much as the same stain applied to a low shading paint with equal porosity. These points need to be considered when comparing different paints.

1.3 This method should only be applied to comparative tests within one laboratory, as numerical results obtained in different laboratories are usually inconsistent.

1.4 Values expressed in SI units shall be regarded as standards. The values given in parentheses are for reference only.

This standard is not intended to address all safety concerns, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
