12、y rubber tubing, approximately 2feet long, shall be attached to tbe bottle.The other end of the tubing shall be con-nectsd to one arm of a Y-tube. By mesns ofnnother piece of rubber tubing and a ehortpiece of glass tubing, the other arm of theY-tube ehall be extended to dip into a vesselcontaining m

This operation shsll be repeateduntil the bottle is tilled with mercury. Thebottle containing the powder and mercuryshall be weighed. Th
15、e same bottle, tilled withmercury shall be weighed. The specific grt-vity shall be calculated as follows:Specific gravity AB divided by (APlus C minus D) where:A = weight of sample taken for test.B = density of mercury at test tem-perature.C = weight of vswel tilled with mer-cury.D = weight of vesse

In case of dis-pute or doubt, the preferred method shall IICthe standard. Add exactly 100 grams of 1-poun
17、d primary sample tn a clean, stmrdard-ized bulb. Place the bulb in a vertical posi-tion, with the lower stem immeracd in themercury reservoir, attach the vacuum pumpto the upper stem, and prnceed to exhaust theair rmd to fdl the space within the bulb withmercury. Dislodge air bubbles that may clinga
18、round the powder grains or to the well ofthe bulb by tapping the bulb gently with arubber atopper while the air is being ex-hausted. Alternately exhaust the air and al-low the mercury to flow up into the bulb infour repeated operations as described. Afterfinally drawing tbe mercury up into the up-pe
19、r stem of the bulb, and after disconnect-ing the vacuum pump, allow the mercuryto settle back into the bulb. Close both stop-cocks, empty both upper and lower stems ofall sxcess mercury, wipe the exterior glo-bules of mercury and weigh the bulb con-taining mercury and powder. This weixhtrepresents t

22、inder,having an internal diameter of approximate-ly 1 inch, shall be weighed to tbe nearest0.1 gm. The cylinder shall be filled with aportion of the l-pound primary sample asClose as possible to the 50-ml mark. l%ecylincier shall be suspended in an uprightposition by a length of cord, and allowed to
23、fall 30 times from a height of J inch ontna rubber cushion. (A standard laboratoryrubber stopper, having a diameter glightlylarger than that nf the base of the graduatedcylinder, has been found satisfactory foruse. ) Care shall be taken to prevent anyoscillation or sidewise motion.
