Description of ASTM-D8625 2025

ASTM D8625-25

Historical Standard: Standard Test Method for Chemical Assessment of Air Cleaning Technologies




ASTM D8625

Scope

1.1 This test method covers the measurement of the removal rate of injected challenge chemicals and ultrafine particles by portable air cleaners. This test method also evaluates the extent that portable air cleaners produce a limited set of reaction byproducts: formaldehyde, ozone, nitrogen oxides (NOx), and ultrafine (<300 nm) particles.

1.2 This test method involves placing a single portable air cleaner in a full-scale chamber. The concentrations of chemicals and ultrafine particles are compared in sequential experiments with the air cleaner on and off. Chemical and particle removal and generation are quantified.

1.3 This test method does not determine all potential byproducts produced by air cleaning devices.

1.4 This test method is not relevant to the efficacy of biological aerosol inactivation by air cleaning devices nor any biological-induced chemistry. This test method is not relevant to the efficacy of radon or radon decay particle removal or induced chemistry. This test method is not directly applicable to in-duct air cleaners.

1.5 This test method does not address any health effects levels of any of the additive agents, challenge chemicals or particles, or byproducts.

1.6 The values stated in SI units are to be regarded as standard. The non-SI units of ppbv, ppmv, and CFM are provided for informational purposes.

1.7 This 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.

1.8 This 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.
