15、e.17.Procedure7.1 Make sure that the sample in the glass jar is of uniformconsistency before removing a specimen for testing.Inspectthe sample to ensure that there are no signs of settling orseparation of the adhesive.If settling or separation are noted,mix the samples thoroughly.Other factors,such
16、as foaming orcontamination may require the samples be replaced.7.2 Test three 10-g specimens from each composite sample.7.3 Weigh about 10 g of adhesive into a small beaker to thenearest 0.01 g.Disperse in 50 mL of hot distilled water andtransfer to a 200-mL volumetric flask.Rinse the beaker withsmall portions of hot distilled water and add rinsings to theflask.Dilute to mark with hot distilled water.Perform duplicatetests on each dispersion prepared in this manner.7.4 Pipet 10 mL of the dispers
