意义及用途

3.1 容器中油漆的腐败通常与使用受污染的原材料有关, 水 (especially recycled washing water), containers, pipes and equipment in manufacturing plants. A simple method is needed to determine the presence or absence of microorganisms in plants that make paints and coatings. Such determination allows manufacturers to identify contamination points (IE。, raw materials or problem management areas in the plant) to help address corruption.

笔记 1: Some contamination of plant areas is expected, as microorganisms are ubiquitous and in practice usually cannot be eliminated (this is what the preservatives in the tank should control). Excessive contamination or contamination of raw materials may exceed the capacity of the preservative. If your plant has excessive contamination, there are disinfection methods including steam, preservatives, bleach, ETC. These should be discussed with your fungicide supplier and used with care. Recycling spoiled or contaminated products is often not feasible, so the importance of proper fungicide levels combined with good plant management practices is self-evident. Your biocide supplier can also help here.

3.2 This test method can be used by people without basic microbiological training, but some training in aseptic techniques is recommended.

笔记 2: The reliability of the results obtained from this test method depends greatly on the technique used. Incorrect techniques can result in sterile samples being contaminated, or worse, contaminated samples appearing sterile (看 5.1). It is recommended that you consult your biocide supplier, raw material supplier or independent testing laboratory to confirm suspicious results.
