Designation:F319116Standard Practice forField Determination of Substrate Water Absorption(Porosity)for Substrates to Receive Resilient Flooring1This standard is issued under the fixed designation F3191;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 determination of whether or nota substrate surface,in lieu of written instruction from a productmanufacturer,is considered porous or non-porous prior to theinstallation of resilient flooring materials.1.2 Although carpet tiles,carpet,wood flooring,coatings,films,paints,self-leveling and trowel-grade underlayments,primers,and other associated products are not specificallyintended to be included in the category of resilient floorcoverings,the procedures included in this practice may beuseful for assessing the substrate water absorption for sub-strates to receive such materials.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.Some specifichazards statements are given in Section 6 on Hazards.2.Referenced Documents2.1 ASTM Standards:2C125 Terminology Relating to Concrete and Concrete Ag-gregatesF141 Terminology Relating to Resilient Floor CoveringsF1869 Test Method for Measuring Moisture Vapor EmissionRate of Concrete Subfloor Using Anhydrous CalciumChloride2.2 Carpet and Rug Institute(CRI)Standard:3CRI Carpet Installation Standard2.3 Resilient Floor Covering Institute(RFCI)Standards:4Recommended Work Practices for Removal of ResilientFloor CoveringsRecommended Installation Practice for Homogenous SheetFlooring,Fully-Adhered3.Terminology3.1 Definitions:3.1.1 See Terminology F141 for definitions of the terms:substrate,above-grade(suspended),on-grade,below grade,concrete,and resilient flooring.3.1.2 See Test Method F1869 for definition of servicetemperature and relative humidity.3.1.3 See Terminology C125 for definition of absorption.3.2 Definitions of Terms Specific to This Standard:3.2.1 absorption,nthe process by which a liquid is drawninto and tends to fill permeable pores in a porous solid body(Terminology C125).3.2.2 absorption rate,ncritical factor in determining howto install many directly applied adhesives,determined by theamount of time necessary for one droplet of water to beabsorbed with increasing length of time for absorption indicat-ing a less absorptive,less porous,substrate surface.4.Summary of Practice4.1 This practice describes the procedure for assessing thesubstrate water absorption(often referred to as substrateporosity)of horizontal,substrate surfaces prior to the installa-tion of resilient floor coverings.The procedure involvesapplying a drop of water to the surface of properly preparedsubstrate,and then determining whether that drop of water isabsorbed within a given time period.5.Significance and Use5.1 The ability of a substrate surface to readily absorb wateris a key indicator in determining how to correctly install many1This practice is under the jurisdiction of ASTM Committee F06 on ResilientFloor Coverings and is the direct responsibility of Subcommittee F06.40 onPractices.Current edition approved Dec.1,2016.Published January 2017.DOI:10.1520/F3191-16.2For 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 Carpet and Rug Institute,100 S.Hamilton St.,Dalton,GA30720,http:/www.carpet-rug.org.4Available from Resilient Floor Covering Institute,115 Broad St.,Suite 201,LaGrange,GA 30240,http:/.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 typesofflooringadhesives,primers,self-levelingunderlayments,and other products.Several flooring industrypublications such as CRIs Carpet Installation Standard,RF-CIs Recommended Installation Practice for HomogenousSheet Flooring,Fully-Adhered,as well as most flooring,adhesive,primer,and underlayment manufacturers referencesubstrate surface porosity criteria in their application instruc-tions since this directly impacts the spread rate of directlyapplied material,the open time,and other critical installationfactors.5.2 Installing flooring products over low or non-absorptive(sometimes referred to as“non-porous”)substrates such asdensely machine-t
