Designation:E302516Standard Guide forTiered Approach to Detection and Characterization of SilverNanomaterials in Textiles1This standard is issued under the fixed designation E3025;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.1.Scope1.1 This guide covers the use of a tiered approach fordetection and characterization of silver nanomaterials in con-sumer textile products made of any combination of natural ormanufactured fibers.1.2 This guide covers,but is not limited to,fabrics and parts(for example,thread,batting)used during the manufacture oftextiles and production of consumer textile products that maycontain silver-based nanomaterials.It does not apply to analy-sis of silver nanomaterials in non-consumer textile productmatrices nor does it cover thin film silver coatings with onlyone dimension in the nanoscale.1.3 This guide is intended to serve as a resource formanufacturers,producers,analysts,policymakers,regulators,and others with an interest in textiles.1.4 This guide is presented in the specific context ofmeasurement of silver nanomaterials;however,the structuredapproach described herein is applicable to other nanomaterialsused to treat consumer textile products.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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:2D123 Terminology Relating to TextilesD6413 Test Method for Flame Resistance of Textiles(Ver-tical Test)2.2 AATCC Standards:3AATCC 135 Dimensional Changes of Fabrics after HomeLaundering2.3 ISO Standards:4ISO 10136-1 Glass and GlasswareAnalysis of ExtractSolutionsPart 1:Determination of Silicon Dioxide byMolecular Absorption SpectrometryISO 16140 Microbiology of Food and Animal FeedingStuffsProtocol for the Validation ofAlternative MethodsISO/IEC Guide 99 International Vocabulary of MetrologyBasic and General Concepts and Associated Terms(VIM)ISO/DTR 18196 NanotechnologiesMeasurement Tech-nique Matrix for the Characterization of Nano-ObjectsISO/TS 80004-1 NanotechnologiesVocabularyPart 1:Core Terms2.4 U.S.Code of Federal Regulations:516 CFR Parts 1615 and 1616 Standards for the Flammabilityof Childrens Sleepwear3.Terminology3.1 DefinitionsFor additional definitions related totextiles,see Terminology D123;for additional definitionsrelated to nanotechnology,see ISO/TS 80004-1;and foradditional definitions related to measurements,see ISO/IECGuide 99.3.1.1 analyte,nelement or constituent to be determined.ISO 10136-13.1.2 consumer textile product,ntextile product intendedto satisfy human wants and needs.D1233.1.3 manufactured fiber,nclass name for various generaof filament,tow,or staple produced from fiber-forming sub-stances that may be:(1)polymers synthesized from chemical1This guide is under the jurisdiction of ASTM Committee E56 on Nanotech-nology and is the direct responsibility of Subcommittee E56.06 on Nano-EnabledConsumer Products.Current edition approved May 1,2016.Published May 2016.DOI:10.1520/E3025-16.2For 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.3Available from American Association of Textile Chemists and Colorists(AATCC),P.O.Box 12215,Research Triangle Park,NC 27709-2215,http:/www.aatcc.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.5Available from U.S.Government Printing Office,Superintendent ofDocuments,732 N.Capitol St.,NW,Washington,DC 20401-0001,http:/www.access.gpo.gov.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 compound,(2)modified or transformed natural polymers,or(3)glass.D1233.1.4 measurand,nquantity intended to be measured or aquantity that is being determined by measurement.ISO/IECGuide 993.1.5 nanomaterial,nmaterial with any external dimen-sion in the nanoscale or having internal structure or surfacestructure in the nanoscale.ISO/TS 80004-13.1.6 nanoscale,nrange from approximately 1 to 100 nm.ISO/TS 80004-13.1.7 natural fiber,nclass name for various genera offibers(including filaments)of(1)animal,(2)mineral,or(3)vegetable origin.D1233.1.8 qualitative method,nmethod of analysis whoseresponse is either the presence or absence of the analytedetected either directly or indirectly in a certain amount ofsample.ISO 161403.1
