Workplace air. Analysis of respirable crystalline silica by Fourier-Transform Infrared spectroscopy1 Scope This document is a standard for the analysis by Fourier Transform Infrared (FTIR) of respirable crystalline silica (RCS) in samples of air collected on collection substrates (i. e. filters or foams). Three analytical approaches are described for whom the dust from the sample collection substrate is a) analysed directly on sampled filter, b) recovered, treated and deposited onto another filter for analysis, or c) recovered, treated and pressed

Conformity assessment and certification based on this standard are envisaged

BS EN 60204-1 gives specific instructions for the safe maintenance of the point where electrical or electronic equipment connects to the machine

— Type P: potable (drinking)

This Part of BS 3680 gives guidance on methods for sampling of both non-cohesive sand-bed material and cohesive-bed material (both of which may contain some fine gravel) principally for the purpose of determining the grain size frequency distribution of the bed material in open channels
