CDN $393.00

This publication was last reviewed and confirmed in 2026.

Workplace air — Quantitative determination of quartz and cristobalite in bulk materials by X-ray powder diffraction methods

SKU: cd440fe85908 Categories: ,

Description

This document specifies three methods for quantitative measurement of crystalline silica (CS) major polymorphs (quartz and cristobalite) mass percentage content in bulk samples using X-ray powder diffraction (XRPD). This document also provides general information about the capabilities and limitations of relevance to laboratories working for routine testing.

Only X-ray diffractometers with Bragg-Brentano geometry are considered. XRPD techniques are used to characterize specimens in the form of loose powders, where the median grain size is between 1 μm and 10 μm physical diameter. Block specimens are not considered.

Although a number of methods of analysis are considered in this document, other XRPD methods of analysis can be considered if they are demonstrated to give equivalent results.

This document also provides general information about the capabilities and limitations of relevance to laboratories working for routine testing.

Only X-ray diffractometers with Bragg-Brentano geometry are considered. XRPD techniques are used to characterize specimens in the form of loose powders, where the median grain size is between 1 μm and 10 μm physical diameter. Block specimens are not considered.

Although a number of methods of analysis are considered in this document, other XRPD methods of analysis can be considered if they are demonstrated to give equivalent results.
