ASTM D 8407 : 2021

1.1This guide describes analytical methods for determining formaldehyde concentrations in air.

1.2The guide is primarily focused on formaldehyde measurement technologies applicable to indoor (including in vehicle and workplace) air and associated environments (that is, chambers or bags, or both, used for formaldehyde emission testing). The described technologies may be applicable to other environments (ambient outdoor).

1.3This guide reviews a range of commercially available technologies that can be used to measure indoor air formaldehyde concentrations. These technologies typically can measure airborne formaldehyde concentrations with detection limits in the range of 0.04 ppb_v (0.05 µg m^-3) to 10 ppb_v (12 µg m^-3). The described technologies are typically applied to research or regulatory applications and not consumer level uses.

1.4This guide describes the principles behind each method and their 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 values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7This 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.

1.8This 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.
