Bursting strength is a test method that can measure the strength of textile products under the influence of force from various directions at the same time.
Don't touch fabrics
Burst strength is extremely important for cloths such as It is also suitable for conditioned or wetted test samples. ( TS EN ISO 13938-2, TS 393/March1975, TS 393 EN ISO 13938-1, BS EN ISO 13938-2)

Bursting strength tester
Features of the explosion strength tester;
The device works with pneumatic or hydraulic pressure method for the determination of bursting strength and bursting surface tension of fabrics.
An elastic diaphragm is loaded onto the fabric while performing the burst strength test, a pressurized fluid is used behind the diaphragm to measure the tension on the fabric. The general view of the device is shown below.
The diaphragm should be up to 2 mm thick and have high expansion.
In the absence of a given specification for the fabric sample example given below It should be used.
For tests carried out in wet conditions, the test sample is immersed in water with a temperature of 20 ºC ± 2 ºC for one hour.
Instead of water, aqueous solutions containing up to 1 gram of wetting reagent per liter can be used.
Immediately after the test sample is taken out of the water, it is placed on a blotting paper for a short time to remove excess water and the test is started.
In this experiment, the determination of bursting strength and bursting surface tension is measured by the pneumatic pressure method.
This measurement is made according to the TSE EN ISO 13938-2 standard.
Sample before experiment conditioning makes.
For fabrics knitted according to the standard, the test area is 50 cm2 (79,8 mm diameter).
However, test areas of 100 cm2 (112,8 mm dia.), 10 cm2 (37,7 mm dia.) and 7,3 cm2 (30,5 mm dia.) can also be used if high or low fabric expansion or other fabric properties are in question. .
The test piece prepared in any of these dimensions is placed on the diaphragm without applying any tension.
The test specimen is firmly attached with a circular fastener.
The device is set to zero and the safety guard is put in place.
The working speed is adjusted to be 20 ± 5 seconds for the test sample to explode.
Pressure is applied to the sample at the specified working speed until the fabric bursts.
After the fabric bursts, the diaphragm returns to its original position.
The height at the time of explosion (mm) and/or the burst volume, burst pressure (kg/cm2, N/cm2) and test time (seconds) are recorded.
Holder jaw ruptures occurring within 2 mm of the attachment line are not accepted.
In such a case, the experiment is repeated at least 4 times from different parts of the fabric.
