Designation: F1862/F1862M − 17Standard Test Method forResistance of Medical Face Masks to Penetration bySynthetic Blood (Horizontal Projection of Fixed Volume at aKnown Velocity) 1This standard is issued under the f i xed designation F1862/F1862M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.INTRODUCTIONWorkers, primarily those in the healthcare profession, involved in treating and caring for individualsinjured or sick, can be exposed to biological liquids capable of transmitting disease. These diseases,which may be caused by a variety of microorganisms, can pose signif i cant risks to life and health. Thisis especially true of blood-borne viruses which cause hepatitis (hepatitis B virus (HBV) and hepatitisC virus (HCV)) and acquired immune def i ciency syndrome (AIDS) (human immunodef i ciency virus(HIV)). Because engineering controls can not eliminate all possible exposures, attention is placed onreducing the potential of direct skin and mucous membrane contact through the use of protectiveclothing that resists penetration (29 CFR Part 1910.1030). This test method was developed for rankingthe synthetic blood penetration resistance performance of medical ace masks in a manner representingactual use as might occur when the face mask is contacted by a high-velocity stream of blood froma punctured wound.1. Scope1.1 This test method is used to evaluate the resistance ofmedical face masks to penetration by the impact of a smallvolume (~2 mL) of a high-velocity stream of synthetic blood.Medical face mask pass/fail determinations are based on visualdetection of synthetic blood penetration.1.2 This test method does not apply to all forms or condi-tions of blood-borne pathogen exposure. Users of the testmethod must review modes for face exposure and assess theappropriateness of this test method for their specif i c applica-tion.1.3 This test method primarily addresses the performance ofmaterials or certain material constructions used in medical facemasks. This test method does not address the performance ofthe medical face mask’s design, construction, or interfaces orother factors with the potential to affect the overall protectionoffered by the medical face mask and its operation (such asf i ltration efficiency and pressure drop). Procedures for measur-ing these properties are contained in Test Method F2101 andMIL-M-36954C.1.4 This test method does not address breathability of themedical face mask materials or any other properties affectingthe ease of breathing through the medical face mask. This testmethod evaluates medical face masks as an item of protectiveclothing. This test method does not evaluate the performanceof medical face masks for airborne exposure pathways or in theprevention of the penetration of aerosolized body f l uids depos-ited on the medical face mask.1.5 The values stated in SI units or inch-pound units are tobe regarded separately as standard. The pressure values statedin each system are not exact equivalents. However, as thecorresponding velocities are within 1 % of each other, (seeX1.4.2), reporting of the results in either units is permitted.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for the1 This test method is under the jurisdiction ofASTM Committee F23 on PersonalProtective Clothing and Equipment and is the direct responsibility of SubcommitteeF23.40 on Biological.Current edition approved June 1, 2017.
