ASTM D3786 Diaphragm Bursting Tester For Leather Paper Card Boards
INTRODUCTION
Materials without specific orientation cannot be tested for
strength on a tensile tester. Test tissue resistance by applying a
multidirectional force generated by static pressure to the tissue
For tissues, this phenomenon is known as the burst strength test.
The automatic hydraulic membrane fracture tester YG032E was
specially developed to perform tissue fracture strength tests in
the form of a kit with pneumatic control. It can also be used for
leather, paper, cardboard, etc.
USAGE
Used to measure the burst strength and burst strain of woven and
knitted fabrics, industrial fabrics, nonwovens, laminated fabrics,
plastics, leather (artificial and natural) and cardboard.
TESTING STANDARDS
ASTM D 3786 Standard Test Method for Hydraulic Bursting Strength of
Textile Fabrics
TEST PROCEDURE
Burst testers have been developed to measure the burst strength of
textile materials exposed to increased hydrostatic pressure. This
pressure is applied through the elastic diaphragm to the circular
area of the sample. The sample is clamped with a pneumatic clamp at
the end of this circular area. When pressure is applied, the sample
deforms with the diaphragm. The burst strength corresponds to the
maximum pressure that the specimen can withstand before it bursts.
Similar to the principle of multi-directional tensile testing, this
measurement does not depend on the cutting direction (mechanical or
cross-shaped) of the sample. This is because, depending on how the
tissue is destroyed, the destruction occurs naturally in the
direction of the least resistance
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
