Designation:D820819Standard Practice forCollection of Non-Fibrous Nanoparticles Using aNanoparticle Respiratory Deposition(NRD)Sampler1This standard is issued under the fixed designation D8208;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 practice describes specified apparatus and proce-dures for collection of non-fibrous airborne metal nanoparticlesgenerated during work activities.1.2 Nanoparticle respiratory deposition(NRD)samplers aredesigned to follow a nanoparticulate matter(NPM)depositioncurve based on the International Commission on RadiologicalProtection(ICRP)model for deposition of particles smallerthan 300 nm(the minimum deposition for submicrometreparticles)while removing the larger particles(1).21.3 This practice is applicable to personal and area samplingduring work processes and situations where metal nanopar-ticles may be generated(for example,welding,smelting,shooting ranges).1.4 This practice is intended for use by professionals expe-rienced in the use of devices for occupational air sampling(such as cyclone samplers).1.5 This practice is not applicable to the sampling of fibrousnanoparticles such as carbon nanotubes.1.6 Detailed operating instructions are not provided owingto differences among various makes and models of suitabledevices and instruments.The user is expected to followspecific instructions provided by the manufacturers of particu-lar items of equipment.This practice does not address com-parative accuracy of different devices nor the precision be-tween instruments of the same make and model.1.7 This practice contains notes that are explanatory and arenot part of the mandatory requirements of the method.1.8 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.9 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.10 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:3D1356 Terminology Relating to Sampling and Analysis ofAtmospheresD4532 Test Method for Respirable Dust in Workplace At-mospheres Using Cyclone SamplersD4840 Guide for Sample Chain-of-Custody ProceduresD5337 Practice for Flow Rate Adjustment of Personal Sam-pling PumpsD6785 Test Method for Determination of Lead in WorkplaceAir Using Flame or Graphite Furnace Atomic AbsorptionSpectrometryD6832 Test Method for the Determination of HexavalentChromium in Workplace Air by Ion Chromatography andSpectrophotometricMeasurementUsing1,5-diphenylcarbazideD7035 Test Method for Determination of Metals and Met-alloids in Airborne Particulate Matter by InductivelyCoupled Plasma Atomic Emission Spectrometry(ICP-AES)D7202 Test Method for Determination of Beryllium in theWorkplace by Extraction and Optical Fluorescence Detec-tionD7439 Test Method for Determination of Elements in Air-borne Particulate Matter by Inductively Coupled Plasma-Mass SpectrometryE1370 Guide for Air Sampling Strategies for Worker andWorkplace Protection1This practice is under the jurisdiction ofASTM Committee D22 on Air Qualityand is the direct responsibility of Subcommittee D22.04 on Workplace Air Quality.Current edition approved June 1,2019.Published June 2019.DOI:10.1520/D8208-19.2The boldface numbers in parentheses refer to a list of references at the end ofthis standard.3For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 2.2 ISO Standards:4ISO 7708 Air QualityParticle Size Fraction Definitions forHealth-Related SamplingISO 13137 Workplace AtmospheresPumps for PersonalSamplingofChemicalandBiologicalAgentsRequirements and Test MethodsISO 13138 Air QualitySampling Conventions for Air-borne Particle Depos
