14、0 mm wide by 60 mm long by 3.2 mm deep,placed on a bright tin panel.Fill the mold with an excess of material,Allow the test specimen to cool at room tempera-ture for at least 12 h;then trim the specimen flush with the face of the mold with a heated metal knife or spatula.NOTE I-A release agent shoul
15、d be used where it is necessary to separate the material being tested from the metai.A nontoxic,water-washable,release agent recommended for this purpose is prepared by grinding into a smooth paste a mixture of approximately 50%talc,35 X glycerin and IS%by weight of a water-soluble medical lubricant
16、.6 6.2 Procedure-Remove the mold and place the panel containing the sample in a forced-draft oven maintained at 140 k 2F(60 ii 1.1C)for 5 h.During the test,mount the panel so that the longitudinal axis of the specimen is at an angle of 75 f 1 with the horizontal,and the transverse axis is horizontal.Measure the change in length in millimetres of the specimen during the 5-h test period,and report as the flow.KY Jelly,available at drug stores,has been found suitable for this purpose NOTICE:This st
