Standard Test Method for Determination of the Microbial Condition of Paint, Paint Raw Materials, and Plant Areas
3.1 Spoilage of paint in the container is often related to the use of contaminated raw materials, water (particularly recycled washwater), vessels, piping, and equipment in the manufacturing plant. There is a need for a simple method to determine the presence or absence of microorganisms in plants that manufacture paints and coatings. Such a determination enables the manufacturer to establish the point of contamination (that is, raw materials or problem housekeeping areas in the plant) to help in solving the spoilage problem.
3.2 This test method may be used by persons without basic microbiological training, but some training on aseptic techniques would be recommended.
1.1 This test method covers a procedure for the determination of the microbial condition (contamination or sterility) of raw materials used in the manufacture of paint, and the microbial condition of paint and paint manufacturing areas.
1.2 The values 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.
