ASTM D8560-24 PDF
1.1This guide describes methods for determining Per- and Polyfluoroalkyl Substances (PFAS) concentrations in indoor air.
1.2This guide is focused on PFAS measurement technologies applicable to indoor air (including in vehicles and indoor workplaces) and other relevant air volumes such as, air in chambers, bags, or both. The described technologies were developed for indoor air; they may or may not be applicable to other types of air samples.
1.3This guide describes available technologies and methods that can be used to measure indoor air PFAS concentrations in the gaseous or particulate phases, or both, in indoor air.
1.4This guide describes each method and its advantages and limitations.
1.5This guide does not attempt to differentiate between the effectiveness of the methods nor determine equivalence of the methods.
1.6The sorbent-based sampling strategies addressed in this guide are for PFAS compounds with a molecular mass greater than 200 g mol-1 (1, 2, 3).2 Compounds less than 200 g mol-1, such as CF4, C2F6, or PFAS degradation products may require real-time analytical methods described in this guide or other methods that are not presented here.
1.7Units-The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.9This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
