Designation:F1383121Standard Test Method forPermeation of Liquids and Gases through ProtectiveClothing Materials under Conditions of Intermittent Contact1This standard is issued under the fixed designation F1383;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEEditorially corrected 8.8.1 in February 2015.INTRODUCTIONWorkers involved in the production,use,and transportation of liquid and gaseous chemicals can beexposed to numerous compounds capable of causing harm upon contact with the human body.Thedeleterious effects of these chemicals can range from acute trauma such as skin irritation and burn,tochronic degenerative disease such as cancer.Since engineering controls may not eliminate all possibleexposures,attention is often placed on reducing the potential for direct skin contact through the useof protective clothing that resists permeation,penetration,and degradation.This test method is used to measure the resistance to permeation under the condition of intermittentcontact of the protective clothing material with liquid or gaseous chemicals.Resistance to permeationand penetration under conditions of continuous contact should be determined by Test Methods F739and F903,respectively.In certain situations,the permeation of liquids through protective clothingmaterials can be measured using a permeation cup following Method F1407.An undesirable changein the physical properties of protective clothing materials is called degradation.Methods formeasuring the degradation of rubbers,plastics,and coated fabrics are found in Test Methods D471,Test Method D543,and Test Method D751,respectively.A starting point for selecting the chemicalsto be used in assessing the chemical resistance of clothing materials is Guide F1001.1.Scope1.1 This test method measures the permeation of liquids andgases through protective clothing materials under the conditionof intermittent contact.1.2 This test method is designed for use when the testchemical is a gas or a liquid;where the liquid is either volatile(that is,having a vapor pressure greater than 1 mm Hg at 25C)or soluble in water or another liquid that does not interact withthe clothing material.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.1.4 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.Specific hazardstatements are given in Section 7.2.Referenced Documents2.1 ASTM Standards:2D471 Test Method for Rubber PropertyEffect of LiquidsD543 Practices for Evaluating the Resistance of Plastics toChemical ReagentsD751 Test Methods for Coated FabricsD1777 Test Method for Thickness of Textile MaterialsE105 Practice for Probability Sampling of MaterialsE171 Practice for Conditioning and Testing Flexible BarrierPackagingE177 Practice for Use of the Terms Precision and Bias inASTM Test MethodsE691 Practice for Conducting an Interlaboratory Study to1This test method is under the jurisdiction ofASTM Committee F23 on PersonalProtective Clothing and Equipment and is the direct responsibility of SubcommitteeF23.30 on Chemicals.Current edition approved Sept.1,2012.Published October 2012.Originallyapproved in 1992.Last previous edition approved in 2011 as F1383-11.DOI:10.1520/F1383-12E01.2For 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 Determine the Precision of a Test MethodF739 Test Method for Permeation of Liquids and Gasesthrough Protective Clothing Materials under Conditions ofContinuous ContactF903 Test Method for Resistance of Materials Used inProtective Clothing to Penetration by LiquidsF1001 Guide for Selection of Chemicals to Evaluate Protec-tive Clothing MaterialsF1194 Guide for Documenting the Results of ChemicalPermeation Testing of Materials Used in Protective Cloth-ingF1407 Test Method for Resistance of Chemical ProtectiveClothing Materials to Liquid PermeationPermeationCup MethodF1494 Terminology Relating to Protective Clothing2.2 ISO Standard:ISO 6529Protective ClothingDetermination of Resis-tance of Protective Clothing Materials to Permeation byLiquids and Gases33.Terminology3.1 Definitions:3.1.1 analytical technique,na procedure whereby theconcentration o
