| Bottles | 6 | Digital balance Height Gage |
Purpose
This procedure determines the amount of shrinkage in a blown container in the first 24 hours after blow molding by evaluating the bottle height and diameters and overfill volume at 0.5, 5 and 24 hours.
Description
Six test bottles are measured 30 minutes, 5 hours and 24 hours after blow molding to determine the bottle height, diameters and overfill volume. The container shrinkage is then determined based on this information.
