Designation:D375895(Reapproved 2010)Standard Practice forEvaluation of Spray-Buff Products on Test Floors1This standard is issued under the fixed designation D3758;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 covers the comparison of the performanceof spray-buff products on test floors against a referencematerial.Spray-buff products are to be used to maintain basefloor-polish films.This technique is intended to be used onwater-emulsion floor polishes with a floor machine not exceed-ing 95 lb(43 kg)in weight and with a rate of rotation of 350rpm or less.1.2 Gloss,heel marking,soil resistance,and slip resistanceof the spray-buffed test panels are rated in comparison to testpanels similarly maintained with a reference spray-buff prod-uct.1.3 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.1.4 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:2D523 Test Method for Specular GlossD1455 Test Method for 60 Specular Gloss of EmulsionFloor Polish2.2 Chemical Specialties Manufacturers Association TestMethods:245-70 Comparative Determination Slip Resistance of FloorPolishes33.Terminology3.1 Definitions:3.1.1 water emulsion floor polishan emulsion-based pol-ish in which water is the continuous or external phase.3.1.2 wax emulsiona water emulsion polish containing apredominance of natural or synthetic waxes,or both.4.Significance and Use4.1 Spray buff products are utilized for the maintenance ofpolished floors.This practice is for the evaluation of a spraybuff product against a reference product.The procedure is afloor test utilizing a rotary-disc floor machine.This practice ascurrently written may or may not be applicable for machines inexcess of 350 R.P.M.5.Apparatus5.1 Floor Machine of the single-disk type,fitted with a paddriver and a spray-buffing floor maintenance pad.5.2 GlossmeterThe instrument and the reference stan-dards shall conform to the requirements prescribed in TestMethod D523,using an angle of reflection of 60.6.Description of Test Area6.1 The preferred area is a corridor in normal traffic serviceexposed to nearly uniform traffic over the test area.6.2 The preferred substrate is vinyl tile.6.3 Divide the area into test sections at least 4 ft(1.2 m)inlength and the full width of the corridor.Use one section foreach test material in addition to the control section.7.Preparation of Test Area7.1 Completely strip the test area of dirt and old floor polish.Thoroughly rinse and dry before applying the base polishes.7.2 Coat two test sections of the corridor with base polish.Maintain one test section with the test spray-buff product andthe other section(control)with a reference spray-buff product.7.2.1 Apply the base polish to the test section,using anysuitable and controlled procedure in accordance with themanufacturers recommendations.1This practice is under the jurisdiction of ASTM Committee D21 on Polishesand is the direct responsibility of Subcommittee D21.04 on Performance Tests.Current edition approved May 1,2010.Published May 2010.Originallyapproved in 1979.Last previous edition approved in 2003 as D3758 95(2003).DOI:10.1520/D3758-95R10.2For 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 Chemical Specialties Manufacturers Assn.,Inc.,1913 EyeStreet,N.W.,Washington,DC 20006.Test Methods and General Information,Waxes,Polishes,and Floor Finishes Div.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 7.2.2 Wait 1 h after the first coat has dried to touch beforethe application of a second coat.Wait 1 h after the second coathas dried to touch before the application of a third coat ofpolish.7.3 In the instance of wax-emulsion polishes,machine buffthe test section coated with the test wax and the referencematerials with a new 00 steel wool pad or clean bristle brushattachment 30 min after the third coat is apparently dry.Allother water emulsion polish types considered in this method donot receive any initial buffing.7.4 Allow each test section to dry 1 h before exposing totraffic.Environmental conditions outside the norms,70 to 90F(21 to 32C),and above 70%relative humid
