YG032E Pneumatic Controlled Automatic Hydraulic Diaphram Bursting
Tester
INTRODUCTION
Textile fabrics having no particular directions cannot be tested
its strength in tensile testers;a multidirectional force generated
by hydrostatic pressure is applied on fabric to check the strength
of that
fabric, this phenomenon is called bursting strength testing.YG032E Automatic Hydraulic Diaphram Bursting Tester is specially designed to perform the bursting strength testing of
kitted fabrics, with pneumatic control.It can also be used for
leather, paper & card Boards etc.
USAGE
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.
Procedure:
- The fabric sample is clamped over the rubber diaphragm.
- The pressure in the fluid increases at such a rate that the
specimen bursts within 20 ± 3 sec. (P1).
- The height (extension) of the diaphragm is noted.
- Another test is carried out without a specimen.
- The pressure to do this is noted and then deducted from the earlier
reading.
- (P1 - P2) is the actual bursting strength of the specimen
