16、 liquid detergent as the wettingagent.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

17、.3 Commercial Scale, good quality calibrated in 1-mm or132-in. increments.8. 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 pip

18、et, if necessary, until 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 star

19、tover.NOTE 3The capacity 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 Ca
