Apparatus7.1 For Determining Bottle Capacity:7.1.1 Balance, having a

15、n accuracy of 60.1 % or better atrated capacity (full scale).7.1.2 Pipet, Graduated Cylinder, and Beaker, as required.7.1.3 Conditioned water at 23 6 2.0C (73.46 3.6F)containing a wetting agent sufficient to flatten the meniscus andeliminate air bubbles.NOTE 2Any liquid detergent may be used as the

16、wetting agent.7.1.4 Stop Watch.7.2 For Determining Finish and Body Dimensions:7.2.1 Micrometers, Vernier Height Gages, or Vernier Cali-pers with an accuracy of 60.025 mm (60.001 in.).7.2.2 Internal Micrometers or Telescoping Gages with anaccuracy of 60.025 mm (60.001 in.).7.2.3 Commercial Scale, goo

Test Methods8.1 Bottle Capacity:8.1.1 Weigh the empty bottle and record the weight ingrams.8.1.2 Fill the bottle to overflow capacity with conditionedwater containing the wetting agent, adjusting the meniscus byuse of a pipet, if necessary, until

18、the meniscus is tangent to thetop of the finish surface. No more than 2 min shall be allowedfor filling the bottle and no additional water shall be added afterthe bottle is filled to overflow and free of air bubbles.8.1.3 If the time exceeds 2 min, discard the sample and startover.NOTE 3The capacity

19、 of the container is somewhat time-dependent inthat the force of the water in the container will cause the container sidesto bulge with time and additional water will be needed to adjust tooverflow capacity.8.1.4 Weigh the filled bottle and record the weight in grams.8.1.5 Calculate the bottle volum
