ISO 19087 is a standard for the analysis of respirable crystalline silica (RCS) in samples of air collected on collection substrates (i.e. filters or foams) by Fourier-Transform Infrared (FTIR). There are three analytical approaches. The dust from the sample collection substrate is: a) analysed directly on sampled filter; or b) recovered, treated and deposited onto another filter for analysis; or c) recovered, treated and pressed into a potassium bromide (KBr) pellet for analysis by the instrument. ISO 19087 will include information on the instrumental parameters, sensitivity of different sampling apparatus, the use of different filters and sample treatment to remove interference. In ISO 19087 the expression respirable crystalline silica (RCS) includes the most common polymorphs quartz and cristobalite. The less common polymorphs of crystalline silica, such as tridymite, are not included within the scope of this part of ISO 19087 because a standard reference material is not available. Under certain circumstances (i.e. low filter dust loads, low silica content), the analytical approach described in this method may not fulfil the expanded uncertainty requirements of ISO
