33、. Test Methods14.1 Test ConditionsUnless otherwise specified, conducttests at the standard laboratory temperature of 23 6 2C (70 to77F). Since this film and sheeting does not absorb water, theimportance of constant humidity during testing is not impor-tant.14.2 Specific GravityDetermine the specific

34、 gravity ontwo specimens in accordance with Method A of Test MethodsD792. Add two drops of a wetting agent (liquid detergent)9tothe water in order to reduce the surface tension and insurecomplete wetting of the sample.14.3 Tensile Properties:14.3.1 Film 0.254 mm (0.010 in.) or less in nominalthickne

If the die is the steel rule type it shall have a curvatureof

36、4 6 0.8 mm (532 6132 in.). Tabs at each end of the dielonger than specified in Fig. 1 are allowed.14.3.2.2 Determine the tensile properties in accordance withthe procedures described in Test Method D638, except that thespecimens shall be as detailed in 14.3.1-14.3.2.1, the initial jawseparation shal

37、l be 22.2 6 0.13 mm (0.875 6 0.005 in.), andthe speed of testing shall be 51 mm/min (2 in./min). Clamp thespecimen with essentially equal lengths of the tabs in each jaw.If an extensiometer is not available, the elongation at break isdetermined from the chart record, expressing the value as apercent

38、age of the initial jaw separation. Average the testresults. In making the test for tensile properties, a full-scaleload of 22.5 kg (50 lb) has been found suitable. If thespecimens break quickly, increase the chart speed so that thechart record for each specimen covers at least 51 mm (2 in.) onthe ti

After theheating period, cool the specimens to 23 6 2C (73.4 6 3.6F),and remeasure them.14.6 CementabilitySeal the treated surface of the materialby the application of controlled heat, pressure, and time ofdwell to an adhesive-coated strip of aluminum sheet.

48、 Measurethe peel strength at a peel angle of 180, and a speed of 30.5cm/min (12 in./min).14.6.1 Procedure for Preparation of Adhesive-Coated Alu-minum:14.6.2 Coat sheets of aluminum 254 by 254 mm (10 by 10in.) evenly with No. 68040 adhesive using a No. 24 “DrawDown” rod and allow to dry in air for 8

49、 h. The thickness ofcoating is not critical but it is important that the coating besmooth and bubble-free. Use methyl ethyl ketone to thin theadhesive if necessary, and for cleaning the equipment.14.6.3 Cut the coated sheets into strips 38.1 by 127 mm (1.5by 5 in.) and store in a desiccator. It is not advisable to preparemore thana2or3-month supply of coated aluminum at onetime, as the adhesive slowly crosslinks in time and sealstrength values are lowered.14.6.4 Cut five 25.4 by 127-mm (1 by 5-in.) sample stripsevenly spaced across the width
