Designation:E1560111Standard Test Method forGravimetric Determination of Nonvolatile Residue FromCleanroom Wipers1This standard is issued under the fixed designation E1560;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.1NOTESection 2.4 editorially corrected in January 2012.1.Scope1.1 This test method covers the determination of solventextractable nonvolatile residue(NVR)from wipers used inassembly,cleaning,or testing of spacecraft,but not from thoseused for analytical surface sampling of hardware.1.2 The NVR of interest is that which can be extracted fromcleanroom wipers using a specified solvent that has beenselected for its extractive qualities.Alternative solvents may beselected,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.1.3.1 ExceptionThe inch-pound units are included forinformation only.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 AreasF24 Test Method for Measuring and Counting ParticulateContamination on SurfacesF50 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 Particles2.2 Military Standards:3MIL-STD-1916 Acceptance on Zero Sampling Inspection2.3 Federal Standards:3Fed.Std.209E Airborne Particulate Cleanliness Classes inCleanrooms and Clean Zones42.4 Other Documents:IEST-RP-CC001 HEPA and ULPA Filters5,6IEST-RP-CC005 Gloves and Finger Cots Used in Clean-rooms and Other Controlled Environments6ISO 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 14644-15,73.Terminology3.1 Definitions:3.1.1 contaminantunwanted molecular or particulate mat-ter that could affect or degrade the performance of thecomponents on which they are deposited.3.1.2 contaminationa process of contaminant transport oraccretion or both.3.1.3 environmentally controlled areacleanrooms,cleanfacilities,controlled work areas,and other enclosures that aredesigned to protect hardware from contamination.Cleanlinessis achieved by controlling airborne particulate matter,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 Dec.1,2011.Published January 2012.Originallyapproved in 1993.Last previous edition approved in 2006 as E1560 06.DOI:10.1520/E1560-11.2For 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.5The use of Di Octyl Phthalate(DOP)in leak testing of filters or filterinstallation is not acceptable.6Available from Institute of Environmental Sciences and Technology(IEST),Arlington Place One,2340 S.Arlington Heights Rd.,Suite 100,Arlington Heights,IL 60005-4516,http:/www.iest.org.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 temperature,relative humidity,materials,garments,and per-sonnel activities.Guidelines for controlled areas can be foundin Practice E2217.3.1.4 high effciency particulate air(HEPA)a term de-scribing filters having an efficiency of 99.97%for removal of0.3-m and larger particles.For this application,filters shallmeet the requirements of IEST-RP-CC001.4 and section 6.1 ofthis test method.3.1.5 molecular contaminant(nonparticulate)may be in agaseous,liquid,or solid state.It may be uniformly or nonuni-formly distributed or be in the form of droplets.Molecularcontaminants account for most of the NVR.3.1.6 NVRthat quanti
