38、O 11127-1.7 Procedure7.1 Carry out the determination in duplicate.7.2 Dry a sufficient quantity of the sample by heating it at (110 5) C for 1 h. Allow to cool to room temperature in the desiccator (5.4).7.3 Weigh the clean, dry pyknometer (5.1) to an accuracy of 0,01 g (m1), introduce into it appro
39、ximately 10 g of the dried sample and reweigh (m2).7.4 Add distilled or deionized water (4.1) to the pyknometer until it is completely filled. Replace the stopper and gently shake the pyknometer to displace air adhering to the test portion. Remove the stopper, fill with water and then replace the st
40、opper, forcing excess water out through the capillary tube. Carefully dry the outside of the pyknometer. Ensure there are no air bubbles present. Reweigh the pyknometer and its contents (m3).7.5 Empty the pyknometer of water and test portion, rinsing several times to remove all traces of abrasive. R
