1、Designation: D2065 03 (Reapproved 2017)Standard Test Method forDetermination of Edge Performance of Composite WoodProducts Under Surfactant Accelerated Moisture Stress1This standard is issued under the fixed designation D2065; the number immediately following the designation indicates the year ofori

2、ginal 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 test method is intended to serve as a means formeasuremen

3、t of swelling and cracking of the coated oruncoated edge of a composite wood substrate that has beensubjected to wetting by a test solution containing surface activeagent.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3

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.1.4 This internatio

7、1 Definitions of Terms Specific to This Standard:3.1.1 crack rating, na numerical value on a scale from 1to 10, with 10 representing no evidence of cracking of the edge(see Test Method D661).3.1.2 composite wood products, nboards or other struc-tural or decorative materials manufactured from wood fi

8、bers,flakes or strands and various resin binders consolidated underheat, or pressure, or both.4. Summary of Test Method4.1 A surfactant solution is placed in a tray that contains asponge. A preweighed and calipered panel with a coated edgeis placed with the edge in contact with the surfactant satura

9、tedsponge for 2 h. The exposed panel is blotted dry, reweighed,recalipered, and inspected for edge cracking. Percentageweight and thickness changes are calculated and recorded.Edge cracking is rated in accordance with Test Method D661and recorded.5. Significance and Use5.1 This test method provides

10、a measure of the dimensionalstability and integrity of the coated edge of various compositewood products under accelerated moisture stress. It is widelyused as an indicator or predictor of the anticipated performanceof composite wood products during exterior exposure. It maybe used for developmental

11、 evaluation of coatings, substrates, orboth. It may also be useful for quality control or monitoring ofthe production of coated or uncoated composite wood prod-ucts.6. Apparatus6.1 Wide Flat Tray or Pan, suitable to contain the requirednumber of sponges and test boards. The sides must be highenough

12、to safely contain at least 6 mm (14 in.) of solution.6.2 Rack or Holder, suitable to support the required numberof test boards at the nominal 60 angle.6.3 Micrometer or Vernier Caliper, of sufficient capacity forthe board thickness to be measured and capable of 0.1 mmaccuracy.6.4 Balance, with suffi

13、cient capacity (typically 400 g) and0.01 g accuracy.6.5 Suitable Saw, for cutting of samples.1This test method is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings, Materials, and Applications and is the direct responsibility ofSubcommittee D01.52 on Factory Coated Wood Produ

17、size.7. Materials7.1 A sufficient supply of test solution.7.2 Appropriately identified test boards cut to proper size.8. Hazards8.1 When using saws, wear goggles, dust mask, and useproper machine safeguards to prevent injury.9. Procedure9.1 See Fig. 1.9.2 Make the required test solution.3Pour soluti

18、on into thetray to saturate all sponges, and allow to reach room tempera-ture. A 6-mm (14 -in.) depth of solution in the tray works well.9.3 Cut board specimens to a suitable size.A10.2-cm (4-in.)by 12.7-cm (5-in.) size has been found to be convenient. The10.2-cm (4-in.) dimension should be the coat

19、ed edge. Prepa-ration of triplicate specimens is recommended.9.4 Measure thickness of the samples along the edge to betested. Three measurements at 2.54-cm (1-in.) intervals (Fig. 2)are recommended for a 10.2-cm (4-in.) specimen. Recordresults.9.5 Weigh the samples to the nearest 0.01 g and record.9

20、.6 Place boards in the tray on sponges as noted in Fig. 1.Ifcoated edges are to be tested, note that the sponges must benarrower than the length (nominally 10.2 cm or 4 in.) of thecontacting coated edges to prevent contact of the solution withthe uncoated edges of the samples. Sponges 9.0-cm (3.5-in

21、.)wide have been used successfully. For the same reason, thecoated face of the board must rest against the sponge at a 60angle to prevent contact of the solution with the uncoated backof the board.9.7 The test duration is 2 h.After 2 h, remove the boards andblot the edges dry with paper towels.9.8 O

22、bserve and record changes as follows:9.8.1 Visually inspect the edges for cracks and record thecrack rating in accordance with Test Method D661. Repeat theobservation 48 h later.9.8.2 Remeasure the thickness of the boards at the samespots measured in 4.4. Record the percent change at each spot,9.8.3

23、 Reweigh the boards and record the weight gain andpercent weight gain, and9.8.4 Calculate averages and standard deviations for thepercent thickness change and percent weight gain.10.
