Test Methods6.1 Standard ConditionsStandard conditions for all tests shall be 23 6 2C 73.4 6 3.6F and 50 6 5 % relative humidity.6.2 Conditioning/Mixing:6
17、.2.1 Store all membrane materials to be tested in an unopened container at standard conditions for at least 24 h before any testspecimens are prepared.6.2.2 Follow the manufacturers instructions for mixing and preparing membrane materials for testing. Thoroughly mixone-component samples before using
18、. Mix two-component compounds in the ratio recommended by the manufacturer.6.3 Test SurfacesIn addition to the mortar test surfaces specified, use other test surfaces when required by the specifier.6.4 PrimerWhen required by the manufacturer, use a primer as directed by the manufacturer on all subst
19、rate materials in testassemblies.6.5 Hardness:6.5.1 Following the manufacturers instructions, apply a film of membrane, 1.5 6 0.1 mm 60 6 5 mils thick, on a 100 by150-mm 4 by 6-in. piece of polyethylene film-coated paper and allow the membrane to cure for 14 days at standard conditions.If more than
20、one application is required, the total time for film application shall not exceed 48 h.6.5.2 After curing, strip the film from the coated paper, cut into pieces, and lay the pieces one upon another to provide a testspecimen meeting the requirements of Test Method D2240.6.5.3 Using a Type 00 hardness
21、 gauge, obtain an instantaneous reading of the film hardness as specified in Test Method D2240.6.6 Weight Loss:6.6.1 Test in compliance with the requirements of Test Method C1250.6.7 Low-Temperature Crack Bridging:6.7.1 Test in compliance with the requirements of Test Method C1305.6.8 Film Thickness

23、he manufacturers directions. Install the film in one applicationunless manufacturers application instructions require application in several coats. If applied in several coats, the test substrate shallbe set in a vertical position between applications, and the complete film thickness shall be accomp
24、lished in 48 h in accordance withthe manufacturers instructions.6.8.3 Immediately after applying the film, place the coated slab on its end, in a vertical position, and let remain in this positionfor 24 h at standard conditions.6.8.4 Using a vernier caliper, measure the thickness of the total assemb
25、ly at five points within 25 mm 1 in. of the top end ofthe slab. Cover the film at each point of measurement with a 25-mm 1 in. square piece of aluminum, 0.5 mm 0.002 in. thick,to prevent point indentation on the film.6.8.5 Cut a 25-mm 1-in. wide band of film from across the top of the mortar strip.
26、Measure the thickness of the test mortarin approximately the same five locations that measurements were made in 6.8.4. Determine the average.6.8.6 Determine the film thickness by subtracting the average test mortar thickness from the average total assembly thickness(test mortar and film).TABLE 1 Hig
