Significance and Use
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.
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.
