This International Standard gives guidelines for the quality assurance of measurements of respirable crystalline silica in air using direct on-filter or indirect X-ray diffraction and infrared analysis methods. The scope of this International Standard includes the following crystalline silica polymorphs: quartz and cristobalite.

These guidelines are also relevant to the analysis of filters obtained from dustiness measurements in accordance with EN 15051[1].

This part of ISO 16000 specifies a method for determination of volatile organic compounds (VOCs) in indoor air and in air sampled for the determination of the emission from products or materials used in indoor environments (according to ISO 16000-1) using test chambers and test cells. The method uses sorbent sampling tubes with subsequent thermal desorption (TD) and gas chromatographic (GC) analysis[13] employing a capillary column and a mass spectrometric (MS) detector with or without additional Flame Ionisation detector (FID).

The method is applicable to the measurement of most GC-compatible vapor-phase organic compounds at concentrations ranging from micrograms per cubic metre to several milligrams per cubic metre. Many very volatile organic compounds (VVOC) and semi-volatile organic compounds (SVOC) can be analysed depending on sorbents used.

This document provides requirements, best practices, and information to achieve sustained quality in the design, manufacture, performance testing, use, and maintenance of the operator enclosure air quality control system. Control of airborne particulate and dilution of CO2 (which is generated by human respiration) within the operator enclosure are addressed in this document. Recommendations are made for operational integration of the air quality control system. Gases and vapours that may be a hazard in the work environment, outside of the operator enclosure are excluded.
