Designation:E173111Standard Test Method forGravimetric Determination of Nonvolatile Residue fromCleanroom Gloves1This standard is issued under the fixed designation E1731;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 test method covers the determination of solventextractable nonvolatile residue(NVR)from gloves used incleanrooms where spacecraft are assembled,cleaned,or tested.1.2 The NVR of interest is that which can be extracted fromgloves using a specified solvent that has been selected for itsextracting qualities,or because it is representative of solventsused in the particular facility.Alternative solvents may be used,but since their use may result in different values beinggenerated,they must be identified in the procedure data sheet.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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.2.Referenced Documents2.1 ASTM Standards:2D1193 Specification for Reagent WaterE2217 Practice for Design and Construction of AerospaceCleanrooms and Contamination Controlled AreasF50 Practice for Continuous Sizing and Counting of Air-borne Particles in Dust-Controlled Areas and CleanRooms Using Instruments Capable of Detecting SingleSub-Micrometre and Larger ParticlesG120 Practice for Determination of Soluble Residual Con-tamination by Soxhlet Extraction2.2 Federal Standards3:Fed Std 209E Airborne Particulate Cleanliness Classes inCleanrooms and Clean Zones42.3 Other Documents:IEST-RP-CC001 HEPA and ULPA Filters5IEST-RP-CC005 Gloves and Finger Cots Used in Clean-rooms and Other Controlled Environments5Industrial Ventilation,A Manual of Recommended Practice6ISO 14644-1 Cleanrooms and Associated ControlledEnvironments,Classification of air cleanliness7ISO 14644-2 Cleanrooms and Associated ControlledEnvironments,Specifications for testing and monitoring toprove continued compliance with ISO 14644-173.Terminology3.1 Definitions:3.1.1 contaminant,nunwanted molecular or particulatematter that could affect or degrade the performance of thecomponents upon which they are deposited.3.1.2 contamination,na process of contaminant transportor accretion,or both.3.1.3 environmentally controlled area,ncleanrooms,clean facilities,controlled work areas,and other enclosures thatare designed to protect hardware from contamination.SeeIndustrial Ventilation,A Manual of Recommended Practice forsuggestions on facility operation.Cleanliness is achieved bycontrolling airborne particulate matter,temperature,relativehumidity,materials,garments,and personnel activities.Guide-lines for controlled areas can be found in Practice E2217.1This test method is under the jurisdiction of ASTM Committee E21 on SpaceSimulation and Applications of Space Technology and is the direct responsibility ofSubcommittee E21.05 on Contamination.Current edition approved May 1,2011.Published June 2011.Originallyapproved in 1995.Last previous edition approved in 2006 as E1731 06.DOI:10.1520/E1731-11.2For 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 Standardization Documents Order Desk,DODSSP,Bldg.4,SectionD,700RobbinsAve.,Philadelphia,PA19111-5098,http:/dodssp.daps.dla.mil.4Fed-Std-209E has been replaced by ISO 14644-1 and-2,but may continue tobe used by mutual agreement.5Available from the Institute of Environmental Sciences and Technology,2340South Arlington Heights Road,Suite 100,Arlington Heights,IL 60005-4516,http:/www.iest.org.6Available from Committee on Industrial Ventilation,American Conference ofGovernmental Industrial Hygienists,1330 Kemper Meadow Dr.,Suite 600,Cincinnati,OH 45240.http:/www.acgih.org/about/committees/c_indvnt.htm.7Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.4 high effciency particulate air(HEPA),na termdescribing filters having an efficiency of 99.97%for removalof 0.3-m and larger particles.For this application,filters shallmeet the requirements of IEST-RP-CC001(2.3 and 6.1 of thistest method).3.1.5 molecular contaminant(nonparticulate),nmay bein a gaseous,liquid,or solid state.It may be uniformly ornonuniformly distributed or be in the form of droplets.Mo-lecular
