Test Method: SATRA TM170

Burst strength and distension - diaphragm method

December 1992

SCOPE

This method is intended to determine the burst strength of a material. The method is applicable to all types of thin flexible material.

PRINCIPLE

A circular test specimen and an underlying elastic diaphragm are clamped around their edges over the top of a chamber. The specimen is gradually stretched into a dome shape by forcing hydraulic fluid into the chamber at a constant rate. The pressure of the fluid at failure of the specimen and the distension, measured in terms of the height of the dome, are recorded.
