    1、Designation: D5069/D5069M 13Standard 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 rev

Scope1.1 This practice covers the preparation or breaking-in ofpaint-roller covers for evaluation.1.2 This p

    3、ractice is applicable to paint-roller covers havingnap lengths up to 13 mm 12 in. 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 may not be exact equivalents; therefore, eachsyst

Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish approp

    6、osen 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.

    7、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-r

    8、oller 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 toap

    9、ply paint at controllable spreading rates.4.1.2 Using a saturated paint-roller cover affordsreproducibility, when repeating a test.5.

Do not increase the areaexcept as necessary to control excess dripping of paint.7.6 Repeat the above procedure as necessary until thefollowing conditions are met:7.6.1 Each loading of the roller cover results are within 10g .35274 oz of each other.

    16、7.6.2 There is so much paint on the surface being used thatthe fully loaded paint-roller cover cannot transfer any morepaint to the surface.7.6.3 When the above conditions are met, there will be somuch paint on the roller cover that constant movement (turningover) is necessary to prevent dripping, a
