Designation:F1670/F1670M08(Reapproved 2014)1Standard Test Method forResistance of Materials Used in Protective Clothing toPenetration by Synthetic Blood1This standard is issued under the fixed designation F1670/F1670M;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.1NOTEUnits information was editorially corrected in June 2014.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,Hepatitis Hepatitis B Virus(HBV)and Hepatitis CVirus(HCV)and Acquired Immune Deficiency Syndrome(AIDS)Human ImmunodeficiencyViruses(HIV).Since engineering controls can not eliminate all possible exposures,attention is placedon reducing the potential of direct skin contact through the use of protective clothing that resistspenetration(29 CFR Part 1910.1030).This test method was developed to help assess the effectivenessof materials used in protective clothing for protecting the wearer against contact with body fluids thatpotentially contain blood-borne pathogens.Using synthetic blood,this test method is intended toidentify protective clothing material candidates for further testing according to a more rigorousprocedure involving a surrogate for blood-borne pathogens.1.Scope1.1 This test method is used to evaluate the resistance ofmaterials used in protective clothing to penetration by syntheticblood under conditions of continuous liquid contact.Protectiveclothing pass/fail determinations are based on visual detectionof synthetic blood penetration.1.1.1 This test method is not always effective in testingprotective clothing materials having thick,inner liners whichreadily absorb the synthetic blood.1.2 This test method is a means for selecting protectiveclothing materials for subsequent testing with a more sophis-ticated barrier test as described in Test Method F1671.1.3 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 work/clothing exposure andassess the appropriateness of this test method for their specificapplication.1.4 This test method addresses only the performance ofmaterials or certain material constructions(for example,seams)used in protective clothing.This test method does notaddress the design,overall construction and components,orinterfaces of garments,or other factors which may affect theoverall protection offered by the protective clothing.1.5 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.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:2D1331 Test Methods for Surface and Interfacial Tension ofSolutions of Paints,Solvents,Solutions of Surface-ActiveAgents,and Related Materials1This 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 15,2014.Published June 2014.Originallyapproved in 1995.Last previous edition approved in 2008 as F1670 08.DOI:10.1520/F1670_F1670M-08R14E01.2For 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 D1777 Test Method for Thickness of Textile MaterialsD3776 Test Methods for Mass Per Unit Area(Weight)ofFabricE105 Practice for Probability Sampling of MaterialsE171 Practice for Conditioning and Testing Flexible BarrierPackagingF903 Test Method for Resistance of Materials Used inProtective Clothing to Penetration by LiquidsF1671 Test Method for Resistance of Materials Used inProtective Clothing to Penetration by Blood-Borne Patho-gens Using Phi-X174 Bacteriophage Penetration as a TestSystem2.2 Military Standard:3MIL-STD-105 Sampling Procedures and Tables for Inspec-tion by Attributes2.3 ANSI/ASQC Standards:4ANSI/ASQC Z1.4 Sampling
