标准范围
This part of ISO 16232 describes the principles of extraction of contaminants from a component either byimmersion in an ultrasonic bath or by applying ultrasonic vibrations directly via sonotrodes. It is preferablyapplied to small and medium sized components of various geometry of which both internal and/or externalsurfaces have to be examined (e.g. joint seals, gears, etc). It is also applicable to small parts to be analysed inbatches.This method can be used on its own or in association with other methods of extraction described in theISO 16232 series.Unless otherwise specified, this part of ISO 16232 deals with particulate contamination only. It does not,therefore, cover appearance defects or contamination by liquid or gaseous materials. It covers the amountand the nature of residual particles resulting from manufacturing processes and from the environment.
