Weigh 3.0 6 0.5
32、 g of the sample into a taredointment tin. Place tin into the vacuum oven and heat at 248F(120C) for 45 min. Vacuum must be continually in operationto draw off flammable solvents and should be maintained at 0.6in. Hg (15 mm Hg) minimum. Remove the tin from the ovenand cap immediately. Place in a des
33、iccator until cooled to roomtemperature. Weigh the tin and dried sample to the nearest0.015 grains (1 mg).NOTE 3This material is usually nonhomogeneous and shall bethoroughly stirred before weighing. The weighing shall also be accom-plished quickly to avoid loss of solvent by volatization.7.3.3 The
34、use of a vacuum oven is mandatory for drying thespecimen because it has no exposed heating surface nor anopen flame, thus avoiding the danger of flashing. The oven alsoprovides an open vacuum to exhaust solvent fumes.7.3.4 The specimen shall be left in the oven for 45 min andno longer. Specimens lef
35、t in for 1 h or more show a definiteincrease in weight.7.3.5 CalculationCalculate the percentage total solids,TS, as follows:TS,%=(B A)/(C A) 100where:A = weight of ointment tin,B = weight of tin and specimen after drying, andC = weight of tin and specimen before drying.7.3.6 PrecisionDuplicate samp
36、les shall be tested for bestresults. Duplicate results obtained by the same analyst, on thesame material, on the same day, in the same laboratory aresuspect if they differ by more than 0.52 % absolute. Thisprocedure has a standard deviation of 0.13.7.4 Lap Shear Strength (Qualification Tests):7.4.1
37、Number of SpecimensA minimum of seven speci-mens shall be tested for the requirement specified in 6.5.7.4.2 Cut sections 1 by 1 in. (25 by 25 mm) and 1 by 2 in.(25 by 50 mm) from 0.25-in. (6-mm) thick ABS sheets. Onesection of each size is required for each specimen (Fig. 1).7.4.3 Clean the surfaces
38、 to be adhered with a cloth damp-ened with methyl ethyl ketone (MEK).NOTE 4The cleaning of the surface with an abusive amount of MEKmay affect the performance of the test. Tests should be conducted todetermine if this is significant.7.4.4 Using a 1-in. (25-mm) natural bristle brush, apply twolayers
39、of cement in immediate succession to the completesurface ofa1by1-in. (25 by 25-mm) sheet section and to thecenter ofa1by2-in. (25 by 50-mm) sheet section.7.4.5 Assemble these sections immediately and rotate the 1by 1-in. (25 by 25-mm) section 180 on the 1 by 2-in. (25 by50-mm) section within 5 s usi
40、ng light hand pressure (approxi-mately12 lbf (2 N).7.4.6 Place the assembled test specimen on a clean, levelsurface, by using the 1 by 2-in. (25 by 50-mm) section as abase. After 30 s, place a 4.4-lb (2-kg) weight on the testspecimen for a period of 3 min, then remove.7.4.7 Store the assembled test
41、specimens at 73.4 6 3.6F(23 6 2C) for 48 to 50 h and test them in a holding fixturesimilar to that shown in Fig. 2.7.4.8 Place the specimen in the holding fixture and adjustthe screws to bring the sample to a vertical position with theface of the 2-in. (50-mm) specimen in contact with the test jigas
42、 shown in Fig. 2 (Note 5). Back off the screw in contact withthe 2-in. specimen slightly, and insert a 0.001-in. (0.02-mm)shim between the screw plate and the specimen. Then bring thebearing plate of the test machine into contact with the top of the2-in. specimen, using care to ensure that the plate
43、 is on ahorizontal plane.7.4.9 Apply the compressive shear at a speed of 0.05 in.(1.25 mm)/min. Express the results in megapascals (or pounds-force per square inch).NOTE 5Alternative jigs may be used if they can be shown to beequivalent.7.4.10 Disregard the lowest and highest value for thecalculatio
44、n of the average lap shear strength.8. Retest and Rejection8.1 If the results of any test(s) do not meet the requirementsof this specification, the test(s) shall be conducted again onlyby agreement between the purchaser and the seller. Under suchagreement, minimum requirements shall not be lowered,
45、nortests omitted, substituted, changed, or modified, nor shallspecification limits be changed. If, upon retest, failure occurs,the quantity of product represented by the test(s) does not meetthe requirements of this specification.9.
