标准范围

ISO 16232-4:2007描述了通过浸入超声波浴或通过超声波电极直接施加超声波振动从部件中提取污染物的原理。它最好适用于各种几何形状的中小型部件，其内表面和/或外表面都经过检查（例如接头密封件、齿轮等）。它也适用于批量分析的小零件。该方法可以单独使用，也可以与ISO 16232系列中描述的其他提取方法结合使用。除非另有规定，ISO 16232-4:2007仅涉及颗粒污染。因此，它不包括外观缺陷或液体或气体材料的污染。它涵盖了制造过程和环境产生的残余颗粒的数量和性质。

ISO 16232-4:2007 describes the principles of extraction of contaminants from a component either by immersion in an ultrasonic bath or by applying ultrasonic vibrations directly via sonotrodes. It is preferably applied to small and medium sized components of various geometry of which both internal and/or external surfaces are examined (e.g. joint seals, gears, etc). It is also applicable to small parts to be analysed in batches.This method can be used on its own or in association with other methods of extraction described in the ISO 16232 series.Unless otherwise specified, ISO 16232-4:2007 deals with particulate contamination only. It does not, therefore, cover appearance defects or contamination by liquid or gaseous materials. It covers the amount and the nature of residual particles resulting from manufacturing processes and from the environment.
