16、d 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.15.1.1 Trowels for the application and metering of the adhe-sive are

17、commercially available with various notching/toothsizes, Depth Width Spacing, with example (Fig. 1).5.2 Flooring Seam Roller or Hand Roller.5.3 Mechanical Convection-Type Oven, or equivalent, ca-pable of maintaining a temperature greater than 158 6 2F(70.0 6 1C) with inside dimensions large enough t

(6.35 mm) plywoodclassified as flooring underlayment type warrantied by themanufacturer.NOTE 1The wood grain of the underlayment should be uniform,unplugged, and with a smooth sanded face.

19、Concrete or cementitiousunderlayment board or similar may also be substituted if appropriate.NOTE 2Consistency and uniformity of the substrate is critical.6.2 Other substrates falling outside wood or cement basedmay also be used.6.3 Adhesive, as recommended by manufacturer.6.4 Flooring Material, as

20、recommended by manufacturer.7. Conditioning7.1 Aconditioned room maintained at a minimum 73 6 3F(22 6 1C) and 50 6 5 % relative humidity for 24 h.8. Sample Preparation8.1 This practice is applicable and used to determine thevarious physical properties when used in conjunction withstandards reference

21、d in 2.1 and may be used with other testingprotocols if referenced within Specification D7799.8.2 Condition room, material and adhesive at a minimum73 6 3F (22 6 1C) and 50 6 5 % relative humidity for 24h.8.3 Determination of time material is to remain in oven isdependent on elevated temperature uti

Procedure9.1 Follow manufacturers recommendations for adhesiveinstallation requirements and recommendations.9.2

23、 The temperature and duration of the test shall beindicated within the Specification D7799. If not noted, thefollowing shall be used: 1 week at 158 6 2F (70.0 6 1C) or2 weeks at 120 6 2F (48.8 6 1C).9.3 Remove the test specimen and allow to cool for threehours at a minimum 73 6 3F (22 6 1C) and 50 6

Report10.1 Report the following:10.1.1 Standard, substrate type and thickness, adhesiveinformation, including application method, trowel size, roller,spray etc.10.1.2 Duration of time and temperature that specimen hasbeen in oven as well as time allowed to come to ambientt

25、emperature must be reported.10.2 Final report should contain both initial and acceleratedaging results for comparison.11. Precision and Bias11.1 Accelerated aging has been used at least since the1930s to determine the impact that age has had on the physicaland adhesion properties of the adhesive to

26、the adherent. Sincethis practice is used to understand the changes in physicalproperties in use over periods of five to ten years or longer, itwould be impractical to pursue an actual precision and biasstudy. Based on this practice and the experience factor thataccelerated aging has provided with it

27、s correlation to age, it isfelt that further studies are unnecessary. See Appendix X1.12.
