Designation:F1862/F1862M13Standard 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 fixed 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 health care profession,involved in treating and caring forindividuals injured or sick,can be exposed to biological liquids capable of transmitting disease.Thesediseases,which may be caused by a variety of microorganisms,can pose significant risks to life andhealth.This is especially true of blood-borne viruses which cause Hepatitis(Hepatitis B Virus(HBV)and Hepatitis C Virus(HCV)and Acquired Immune Deficiency Syndrome(AIDS)HumanImmunodeficiency Virus(HIV).Because engineering controls can not eliminate all possibleexposures,attention is placed on reducing the potential of direct skin and mucous membrane contactthrough the use of protective clothing that resists penetration(29 CFR Part 1910.1030).This testmethod was developed for ranking the synthetic blood penetration resistance performance of medicalace masks in a manner representing actual use as might occur when the face mask is contacted by ahigh velocity stream of blood from a 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 specific 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 masks design,construction,or interfaces orother factors with the potential to affect the overall protectionoffered by the medical face mask and its operation(such asfiltration efficiency and pressure drop).Procedures for measur-ing these properties are contained in Test Methods 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 fluids 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.2.Referenced Documents2.1 ASTM Standards:21This 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 Dec.1,2013.Published December 2013.Originallyapproved in 1998.Last previous edition approved in 2007 as F1862-07.DOI:10.1520/F1862_F1862M-13.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 D891 Test Methods for Specific Gravity,Apparent,of LiquidIndustrial ChemicalsD1331 Test Methods for Surface and Interfacial Tension ofSolutions of Paints,Solvents,Solutions of Surface-ActiveAgents,and Related MaterialsE105 Practice for Probability Sampling of MaterialsE171 Practice for Conditioning and Testing Flexible BarrierPackagingF1494 Terminology Relating to Protective ClothingF1670 Test Method for Resistance of Materials Used inProtective Clothing to Penetration by Synthetic BloodF1671 Test Method for Resistance of Materials Used inProtective Clothing to Penetration by Blood-Borne Patho-gens Using Phi-X174 Bacteriophage Penetration as a TestSystemF2101 Test Method f
