Designation:F92513Standard Test Method forResistance to Chemicals of Resilient Flooring1This standard is issued under the fixed designation F925;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This test method provides a procedure for determiningthe resistance of resilient floor covering to surface deteriorationwhen exposed to various chemical reagents.This test method isnot intended as a staining test nor as a method to judge surfaceand appearance restoration of the sample after exposure to thechemical reagent.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 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 hazardinformation is provided in Section 6 of this test method.2.Referenced Documents2.1 ASTM Standards:2D2244 Practice for Calculation of Color Tolerances andColor Differences from Instrumentally Measured ColorCoordinatesF141 Terminology Relating to Resilient Floor CoveringsF142 Test Method for Indentation of Resilient Floor Tiles(McBurney Test)(Withdrawn 2007)3F386 Test Method for Thickness of Resilient Flooring Ma-terials Having Flat SurfacesF1914 Test Methods for Short-Term Indentation and Re-sidual Indentation of Resilient Floor Covering3.Terminology3.1 For terminology relating to Resilient Floor Coverings,see Terminology F141.4.Significance and Use4.1 Resilient flooring products are designed and formulatedto have good resistance to most common chemicals encoun-tered in typical use.High performance wear layers can also beused to enhance cleanability and chemical resistance.Resilientflooring used in residential and commercial environments maybe subjected to a variety of chemicals through accidentalspillage or as ingredients used for hygienic purposes.Perfor-mance is dependent upon the flooring formulation and that ofthe maintenance products used on the flooring.This testmethod provides a means of estimating the relative suscepti-bility of resilient floor covering to change when exposed tochemical reagents.5.Apparatus5.1 Gloves,impervious vinyl or rubber,5.2 Tweezers,or forceps,5.3 Medicine Dropper,3 in.straight glass with rubber bulbor pipette having a point opening diameter not less than116in.(1.6 mm)or greater than564in.(1.8 mm),5.4 White Facial Tissue.5.5 Watch Glass.5.6 Timer.5.7 Filter Paper.5.8 Small Laboratory Spatula,approximately1412in.-wide blade,rounded bottom,not sharpened,5.9 Suitable Spectrophotometer or Colorimeter,with a mini-mum14in.(6.35 mm)diameter opening having a cool whitefluorescent(CWF)or daylight(D-65)light source,or both,thatmeasures color in CIE L*,a*,b*using CIE 10 standardobserver and specular included(see Test Method D2244).5.10 Indentation Tester,see Test Methods F142 and F1914.5.11 Thickness Tester,see Test Method F386.1This test method is under the jurisdiction ofASTM Committee F06 on ResilientFloor Coverings and is the direct responsibility of Subcommittee F06.30 on TestMethods-Performance.Current edition approved May 1,2013.Published May 2013.Originallyapproved in 1985.Last previous edition approved in 2008 as F92502(2008).DOI:10.1520/F0925-13.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.12 Conditioning Room or Cabinet,equipped with auto-matic temperature and humidity controls that will maintain73.4 6 3.6F(23 6 2C)and 50 6 5%relative humidity.6.Hazards6.1 A new medicine dropper or pipette should be used foreach test reagent.If the same reagent dispenser apparatus is tobe reused,it shall be thoroughly cleaned in hot soapy water andalcohol,or both,prior to applying each different test reagent.6.2 Check to be sure the colorimeter is properly warmed upand calibrated prior to use.6.3 Be sure specimens are held flat when measuring color.6.4 Be sure each specimen is marked in the corner on theback for easy identification.6.5 Dispose of chemical test reagents properly.Refer toMaterial Safety Data Sheets(MSDS)or precautions on thelabel for proper disposal.(WarningObserv
