GSO ASTM F1862/F1862M:2022 Scope
1.1 This test method is used to evaluate the resistance of
medical face masks to penetration by the impact of a small
volume (~2 mL) of a high-velocity stream of synthetic blood.
Medical face mask pass/fail determinations are based on visual
detection of synthetic blood penetration.
1.2 This test method does not apply to all forms or conditions of blood-borne pathogen exposure. Users of the test
method must review modes for face exposure and assess the
appropriateness of this test method for their specific application.
1.3 This test method primarily addresses the performance of
materials or certain material constructions used in medical face
masks. This test method does not address the performance of
the medical face mask’s design, construction, or interfaces or
other factors with the potential to affect the overall protection
offered by the medical face mask and its operation (such as
filtration efficiency and pressure drop). Procedures for measuring these properties are contained in Test Method F2101 and
MIL-M-36954C.
1.4 This test method does not address breathability of the
medical face mask materials or any other properties affecting
the ease of breathing through the medical face mask. This test
method evaluates medical face masks as an item of protective
clothing. This test method does not evaluate the performance
of medical face masks for airborne exposure pathways or in the
prevention of the penetration of aerosolized body fluids deposited on the medical face mask.
1.5 The values stated in SI units or inch-pound units are to
be regarded separately as standard. The pressure values stated
in each system are not exact equivalents. However, as the
corresponding velocities are within 1 % of each other, (see
X1.4.2), reporting of the results in either units is permitted.
1.6 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.
