标准范围

ISO 14644-8:20 06涵盖了洁净室和相关受控环境中特定化学物质（单个、组或类别）的空气传播浓度的空气传播分子污染（AMC）的分类，并提供了一个方案，包括分类规范中的测试方法、分析和时间加权因子。ISO 14644-8:20 06目前只考虑浓度在100到10之间的AMC？在洁净室操作条件下为12 g/m3。ISO 14644-8:20 06不适用于那些不认为空气传播的分子物质对产品或工艺构成风险的行业、工艺或生产。ISO 14644-8:20 06无意描述空气传播的分子污染物的性质。ISO 14644-8:20 06没有给出表面分子污染的分类。

ISO 14644-8:2006 covers the classification of airborne molecular contamination (AMC) in cleanrooms and associated controlled environments in terms of airborne concentrations of specific chemical substances (individual, group or category) and provides a protocol to include test methods, analysis and time weighted factors within the specification for classification.ISO 14644-8:2006 currently considers only concentrations of AMC between 10⁰ and 10^?12 g/m³ under cleanroom operational conditions.ISO 14644-8:2006 is not relevant for application in those industries, processes or production, where the presence of airborne molecular substances is not considered a risk to the product or process.It is not the intention of ISO 14644-8:2006 to describe the nature of airborne molecular contaminants.ISO 14644-8:2006 does not give a classification of surface molecular contamination.
