ASTM E 3179 : 2025

1.1This test method defines test conditions to evaluate ultraviolet germicidal irradiation (UVGI) light devices (mercury vapor bulbs, light-emitting diodes, or xenon arc lamps) that are designed to kill/inactivate influenza virus deposited on inanimate carriers.

1.2This test method defines the terminology and methodology associated with the ultraviolet (UV) spectrum and evaluating UVGI dose.

1.3This test method defines the testing considerations that can reduce UVGI surface kill effectiveness (that is, soiling).

1.4Protocols for adjusting the UVGI dose to impact the reductions in levels of viable influenza virus are provided (Annex A1).

1.5This test method does not address shadowing.

1.6The test method should only be used by those trained in microbiology and in accordance with the guidance provided by CDC BMBL, Biosafety in Microbiological and Biomedical Laboratories.

1.7This test method is specific to influenza viruses.

1.8The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.9Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.

1.10This 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.

1.11This 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.
