ASTM WK64317

    New Test Method for Quantitative Smoke Inspection Method Used in Protective Clothing to Determine Resistance of Materials to Penetration by Particulates

    (What is a Work Item?)

    Developed by Subcommittee: F23.30 | Committee F23 | Contact Staff Manager


    1. Scope

    1.1 This test method is used to inspect and measure specimens of protective clothing materials, assemblies such as seams and closures, or interfaces used in the construction of protective clothing. The resistance to penetration of the test smoke is determined with the smoke in continuous contact with the normally outside (exterior) surface of the specimen. 1.1.1 This test method particles in the size range of 1 to 10 m in mass mean aerodynamic diameter and flow rates of 1.7 0.2 L/min. 1.2 This test method measures filtration efficiency measuring the reduction in light transmittance across the fabric with a lightmeter. 1.3 This test method does not address penetration of liquid through protective clothing materials. 1.4 This test method is not applicable to non-planar protective clothing materials, interfaces, or assemblies such as the finger tips or crotch areas of gloves, which are possible failure points. 1.5 This test method does not address the particulate penetration resistance of full protective clothing or ensembles. Methodology specified in NFPA 1994 or Test Operating Procedure 10-2-022A is available for this for this purpose.


    Particle blocking


    There are currently no standards that are positioned in the marketplace to assess the ability of protective clothing materials to attenuate the penetration of particles, particular smoke and other hazardous airborne particles that may be encountered in firefighting. The majority of current methods for particle penetration resistance involve filtration-like methods that are not representative of how particles are encountered by end users of protective clothing. There is a need for a simple, inexpensive method that can be used to evaluate protective clothing materials and whole articles of clothing in a non-destructive manner, which can be applied to design, development, and inspection of in-service protective clothing.

    The title and scope are in draft form and are under development within this ASTM Committee.
