Workplace air — Analysis of respirable crystalline silica by Fourier-Transform Infrared spectroscopy

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 into a potassium bromide (KBr) pellet for analysis. This document provides information on the instrumental parameters, the sensitivity of different sampling apparatus, the use of different filters and sample treatment to remove interference. In this document the expression RCS includes the most common polymorphs quartz and cristobalite. This document excludes the less common polymorphs of crystalline silica, such as tridymite. Under certain circumstances (i.e. low filter dust loads, low silica content), the analytical approach described in this method cannot fulfil the expanded uncertainty requirements of ISO 20581. Guidance for calculation of uncertainty for measurements of RCS is given in ISO 24095.

Air des lieux de travail — Mesure de la fraction alvéolaire de la silice cristalline par spectrométrie infrarouge

Zrak na delovnem mestu - Analiza respirabilnega kristaliničnega kremena z infrardečo spektroskopijo s Fourierjevo transformacijo (FTIR)

Ta dokument je standard za analizo z infrardečo spektroskopijo s Fourierjevo transformacijo (FTIR) respirabilnega kristalnega kremena (RCS) v vzorcih zraka, zbranih na zbirnih podlagah (filtrih ali penah). Opisani so trije analitični pristopi, pri katerih se prah z vzorčne zbirne podlage
a) analizira neposredno s filtra z vzorcem,
b) zbere, obdela in odloži na drugem filtru za analizo,
c) zbere, obdela in vtisne v pelet iz kalijevega bromida (KBr) za analizo.
Ta dokument podaja informacije o instrumentalnih parametrih, občutljivosti različnih naprav za vzorčenje, uporabi različnih filtrov in vzorčni obdelavi za odstranjevanje motenj. V tem dokumentu izraz RCS vključuje najpogostejši polimorfni kremen in kristobalit. Ta dokument ne zajema manj pogostih oblik kristalnega kremena, kot je tridimit.
Pod določenimi pogoji (majhne količine prahu filtra, majhna vsebnost kremena) analitični pristop, opisan v tej metodi, ne more izpolnjevati razširjenih zahtev negotovosti standarda ISO 20581. Vodilo za izračun negotovosti meritev RCS je podano v standardu ISO 24095.
