ABSTRACT:
Apparatus for testing a surface coating on a glass container. In this apparatus, a glass container is chucked in place on a movable carriage. A second glass container is held in a fixed position above and touching the first glass container. A load of a pre-determined magnitude is then applied normal to the second glass container, the load thereby being transmitted to the first glass container. The carriage is moved to cause the two glass containers to translate relative to one another. The force required to move the carriage is transmitted through a load cell which gives an output signal indicative of the force. The surface coatings applied to the glass containers should withstand a normal load of about one hundred pounds before breaking down and allowing the glass containers to scratch one another. If a scratch occurs during the test, the force required to move the carriage will increase and this may be easily seen.
