Purpose

This procedure tests the performance of bottles as they are pasteurized.

Description

Eight (8) bottles are measured to determine the bottle diameters at several locations, the base material distribution, the push-up height, the overfill volume and the perpendicularity. The bottles are then carbonated to 2.95-3.13 volumes of CO2, and allowed to equilibrate. The bottles are placed into a pasteurization spray chamber and sprayed with controlled hot water until the internal water temperature reaches the targeted temperature at the coldest spot in the container. The temperature is then maintained for a predetermined amount of time. The bottles are then sprayed with cold water until the internal water temperature decreases to 40°C. The bottles are then removed and remeasured.
