New method for measuring the impact strength of glass containers.

Noguchi, A., Itami, H. and Yokokura, S.

Abstract
Impact is obviously one of the most frequent causes of breakage of commercial glass containers. However, few appropriate methods have been developed to measure the impact strength of glass bottles. This paper presents a new method for measuring impact strength by allowing bottles released from a 15 degree to 65 degree angle to fall and impact horizontally on an acrylic board or iron board a certain number of times. The thickness of the board ranges from 15 to 50 mm depending on the kind of bottle tested. This method is simple and functions well in comparing the impact strength of various kinds of bottles.
