ASTM WK40215

    Work Item: ASTM WK40215 - New Test Method for Applying Aerosolized Threat Representative Viruses On Inanimate Surfaces

    (What is a Work Item?)

    Developed by Subcommittee: E35.15 | Committee E35 | Contact Staff Manager



    1. Scope

    The method will provide guidance for applying aerosolized Helicoverpa zea single capsid nucleopolyhedrovirus (HzSNPV) virus onto surfaces ; subsequent decontamination testing of the virus or evaluation on germicidal surfaces will follow. HZSNPV is a simulant virus for Variola. Methods for fluidizing, stabilizing the virus, and preparing threat representative aerosol conditions will be provided.

    The method by which microorganisms are applied to a surface will impact the ability to decontaminate them for some decontamination processes. This standard is focused on mimicking methods of contamination that would be likely during a viral biological attack. It also proposes the use of a novel BSL-1 simulant virus, which will simply its use. The method will provide a means to test decontamination methods that may be needed to be used following a malicious bioaerosol attack.
