AUTOMATIC HYDRAULIC DIAPHRAM BURSTING TESTER

Introduction

Textile fabrics having no particular directions cannot be tested its strength via tensile testers;

a multi-directional force generated by hydrostatic pressure is applied on fabric to check the strength of that

fabric, this phenomenon is called bursting strength testing. Automatic Hydraulic Diaphram Bursting Tester is specially designed to perform the bursting strength testing of kitted fabrics. It can also be used for leather, paper & card Boards etc.

Application

Textile burst strength tester is mainly to determine the bursting strength and distension at burst of woven and knitted fabrics as well as technical textiles,non-wovens,bonded fabrics,plastics,leather (artificial and natural) and cardboard.

Test Procedure

The Burst Tester is designed for measuring the bursting strength of fabric materials subjected to an increasing hydrostatic pressure. This pressure is applied to a circular region of the specimen via an elastic diaphragm. The specimen is firmly held round the edge of this circular region by a pneumatic clamping device. When the pressure is applied, the specimen deforms together with the diaphragm. The bursting strength corresponds to the maximum pressure supported by the specimen before failure. Identical, in the principle to the multi-directional tensile test, Ball Burst Method for Fabrics, this measurement is independent from the cutting direction of the sample (machine or cross) since the failure naturally occurs in the least resistance direction.
