Note:
This document is a standard for the analysis of RCS in samples of air collected on filters by x-ray diffraction, whenusing an analytical approach where the dust on the air sample filter is analysed by the instrument. This standard will include information on the instrumental parameters, sensitivity of different sampling apparatus, use of different filters, sample treatment to remove interference and absorption correction for depth and absorption affects. The expression respirable crystalline silica includes the most common polymorphs of quartz and cristobalite. The less common polymorphs of crystalline silica, such as Tridymite, are not included within the scope of this document.
