Standard Test Method for Resistance of Emulsion Paints in the Container to Attack by Microorganisms
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the relative resistance of emulsion paints to attack in the container by microorganisms.
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
4.1 Spoilage of paint in the container can result in putrefaction, lowered pH, gas formation, and decrease in viscosity. This test method provides a standard procedure for the evaluation of the resistance of emulsion paints to microbial deterioration. The results should enable: (1) the paint manufacturer to select an effective preservative and (2) the supplier of preservatives to evaluate the performance in emulsion paints of competitive and developmental preservatives.
4.2 This test method should be used preferably by persons who have had basic microbiological training.
