Workplace air. Analysis of respirable crystalline silica by X-ray diffraction - Direct-on-filter method Ingestion-build-115288 Decisions are frequently made by1 Scope This part of ISO 16258 specifies the analysis of respirable crystalline silica (RCS) in samples of air collected on 25 mm filters by X ray diffraction, when using an analytical approach where the dust on the air sample filter is directly analysed by the instrument. This part of ISO 16258 includes information on the instrumental parameters, sensitivity of different sampling apparatus, uses of different filters and correction for absorption
