Designation:D5069/D5069M13(Reapproved 2019)Standard Practice forPreparation of Paint-Roller Covers for Evaluation ofArchitectural Coatings1This standard is issued under the fixed designation D5069/D5069M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the preparation or breaking-in ofpaint-roller covers for evaluation.1.2 This practice is applicable to paint-roller covers havingnap lengths up to 13 mm 12in.Longer pile rollers can beadapted.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system are not necessarily exact equivalents;therefore,toensure conformance with the standard,each system shall beused independently of the other,and values from the twosystems shall not be combined.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D3924 Specification for Standard Environment for Condi-tioning and Testing Paint,Varnish,Lacquer,and RelatedMaterials(Withdrawn 2016)33.Summary of Practice3.1 Using the paint chosen for the evaluation,the paint-roller cover to be tested is repeatedly and generously loadedwith paint and painted out over the same area until it issaturated with paint,that is,the paint-roller cover cannot pickup any more paint,nor apply any more paint to the area beingused for break-in.4.Significance and Use4.1 Until a paint-roller cover is saturated with paint,onlypart of the paint loaded onto the paint-roller cover can betransferred to a surface being painted.The remainder of thepaint is absorbed into the fabric of the paint-roller cover.Theamount of paint absorbed by a paint-roller cover is inverselyproportional to the amount already present within the paint-roller cover.By saturating the paint-roller cover before testing,quantitative inaccuracies of the amount of paint delivered to asurface are eliminated.4.1.1 Using a saturated paint-roller cover enables the user toapply paint at controllable spreading rates.4.1.2 Usingasaturatedpaint-rollercoveraffordsreproducibility,when repeating a test.5.Apparatus5.1 Paint Tray.5.2 Paint Roller Frame,of the same size as the paint-rollercover being prepared.6.Materials6.1 Paint,to be used in test.6.2 Primed or Smooth Surface,to be used for the roller-cover break-in.7.Procedure7.1 All tests are to be conducted in an atmosphere having atemperature of 23 6 2C 73.5 6 3.5F and a relativehumidity of 50 6 5%(see Specification D3924).7.2 Place the paint-roller cover on the frame.7.3 Load the cover/frame with paint thoroughly working thecover back and forth(use roll off area and slowly work into thepool of paint)a minimum of 20 back and forth strokes until the1This practice is under the jurisdiction of ASTM Committee D01 on Paint andRelated Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.61 on Paint Application Tools.Current edition approved Oct.1,2019.Published October 2019.Originallyapproved in 1990.Last previous edition approved in 2013 as D5069 13.DOI:10.1520/D5069_D5069M-13R19.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 cover is uniformly loaded.The cover may require hand rotationto achieve a uniform loading.See Fig.1.7.4 Roll out the roller cover on the surface being used forbreak-in in an upward and downward motion in no larger anarea than 1.22 m 4 ft high by the width of the roller cover.7.5 Reload the paint-roller cover with paint and roll out inthe same manner over the same area.Do not incr
