1、Designation: D 5069 07Standard Practice forPreparation of Paint-Roller Covers for Evaluation ofArchitectural Coatings1This standard is issued under the fixed designation D 5069; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the y

2、ear of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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

3、applicable to paint-roller covers havingnap lengths up to 13 mm (12 in.). Longer pile rollers can beadapted.1.3 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.4 This standard does not purport to address the safetyconcerns, i

4、f any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.

5、ing andTesting Paint, Varnish, Lacquer, and Related Materials3. 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-r

6、oller 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

7、 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 pa

8、int 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 Using a saturated paint-roller cover affords reproduc-ibility, when repeating a test.5. Apparatus5.1 Paint Tray.5.2 Paint Roller Frame, of the same

9、 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

10、% (see Specification D 3924).7.2 Place the paint-roller cover on the frame.7.3 Load the paint-roller cover with the paint from the trayby rolling the paint-roller cover over the surface of the paint sothat just the nap is submersed. See Fig. 1.7.4 Roll out the roller cover on the surface being used

11、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 increase the areaexcept as necessary to control excess dripping of paint.7.

12、6 Repeat the above procedure as necessary until thefollowing conditions are met:7.6.1 Reloading the paint-roller cover does not result insubstantial increased paint pickup.7.6.2 There is so much paint on the surface being used thatthe fully loaded paint-roller cover cannot transfer any morepaint to

13、the surface.1Precision and Bias This practice is under the jurisdiction of ASTM CommitteeD01 on Paint and Related Coatings, Materials, and Applications and is the directresponsibility of Subcommittee D01.61 on Paint Application Tools.Current edition approved Nov. 1, 2007.

16、 and the panel will showprofuse sagging of the paint. About six roller-cover loadingsare usually necessary to achieve this.7.7 The roller cover is now prepared for immediate testing.8.9.
