1.1 本试验方法涵盖了测定涂料生产中使用的原材料的微生物条件（污染或无菌）以及涂料和涂料生产区域的微生物条件的程序。 1.2 以国际单位制为单位的数值将被视为标准。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 容器内油漆的损坏通常与制造厂使用受污染的原材料、水（尤其是回收的洗涤水）、容器、管道和设备有关。需要一种简单的方法来确定制造油漆和涂料的工厂中是否存在微生物。 这样的确定使制造商能够确定污染点（即工厂中的原材料或问题清洁区），以帮助解决腐败问题。 注1: 由于微生物无处不在，通常无法实际消除，因此预计工厂区域会受到一些污染（这是罐装防腐剂应该控制的）。过多的污染或受污染的原材料可能超过防腐剂的能力。如果工厂中有过多的污染，有一些去污方法，包括蒸汽、防腐剂、漂白剂等。 应与杀菌剂供应商讨论这些问题，并小心使用。回收变质或受污染的产品通常是不可行的，因此适当水平的杀菌剂与良好的工厂内务管理实践是必不可少的。您的杀菌剂供应商也可以在此提供帮助。 3.2 本试验方法可供未经基本微生物培训的人员使用，但建议进行一些无菌技术培训。 注2: 从该试验方法中获得的结果的可靠性在很大程度上取决于所采用的技术。不适当的技术可能会导致无菌样品看起来被污染，甚至更糟的是，受污染的样品看起来是无菌的（另请参阅 5.1 ). 建议您咨询您的杀菌剂供应商、原材料供应商或独立测试实验室，以确认可疑结果。

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== 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. Note 1: Some contamination in plant areas is to be expected, since microorganisms are ubiquitous and cannot generally be eliminated practically (it is what an in-can preservative is supposed to control). Excessive levels of contamination or contaminated raw materials can exceed the capability of the preservative. If you have excessive contamination in the plant, there are methods for decontamination including steam, preservatives, bleach, etc. These should be discussed with your biocide supplier and used with care. Recovery of spoiled or contaminated products is often not feasible, so an adequate level of the appropriate biocide in conjunction with good plant housekeeping practices are essential. Your biocide supplier can also help here. 3.2 This test method may be used by persons without basic microbiological training, but some training on aseptic techniques would be recommended. Note 2: The reliability of the results obtained from this test method is extremely dependent on the techniques employed. Improper techniques can result in a sterile sample appearing to be contaminated, and even worse, a contaminated sample appearing to be sterile (see also 5.1 ). It is recommended that you consult with your biocide supplier, raw material supplier, or an independent testing laboratory to confirm questionable results.
