ASTM E2720-16

1.1 This practice is designed to evaluate decontamination methods (physical, chemical, self-decontaminating materials) when used on air-permeable materials contaminated with virus-containing droplet nuclei.

1.2 This practice defines the conditions for simulating respiratory droplet nuclei produced by humans.

1.3 The practice is specific to influenza viruses, but could be adapted for work with other types of respiratory viruses or surrogates.

1.4 This practice is suitable only for air-permeable materials.

1.5 This practice does not address the performance of decontaminants against microbes expelled via blood splatter, vomit, or fecal contamination.

1.6 This practice should be performed only by those trained in bioaerosols, microbiology, or virology, or combinations thereof.

1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.8 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 and health practices and determine the applicability of regulatory limitations prior to use.
