Introducing ISO 13938-1:2019 - Industrial Physics
ISO 13938-1:2019 is a global standard to determine the bursting properties of fabrics using a hydraulic method.
The method is applicable to knitted, woven, nonwoven and laminated fabrics and it’s also suitable for test specimens in the conditioned or wet state.
This ISO standard will enable you to determine the bursting strength and bursting distension of This document describes a hydraulic method for the determination of bursting strength and bursting distension of textile fabrics.
Through the ISO 13938-1:2019 process, a hydraulic pressure is applied using a constant rate of pumping device.
ISO 13938-1:2019 bursting strength considerations
You clamp your test specimen over an expansive diaphragm using a circular clamping ring. Next up - apply increasing air pressure to the underside of the diaphragm. This will cause distension of the diaphragm and the fabric itself.
Next for ISO 13938-1:2019 testing, the pressure is increased smoothly until the test specimen bursts. From here you can determine the bursting strength and the bursting distension.
The available data doesn’t show much significant difference in the bursting strength results achieved using hydraulic or pneumatic burst testers, for pressures up to 800 kPa. This is a pressure range that covers most performance levels expected of general apparel. If you’re using specialty textiles that need high bursting pressures, the hydraulic apparatus is more appropriate.
ISO 13938-1:2019 sampling
You should select samples in accordance with the ISO 13938-1:2019 method, by following a procedure laid down in the material specification for the fabric, or as otherwise agreed between the interested parties.
Suitable ISO 13938-1:2019 samples don’t contain folds or creases. They’re representative of the fabric as a whole and the system of clamping recommended typically negates the need to cut out test specimens.
ISO 13938-1:2019 testing devices
So, how can Industrial Physics improve your ISO 13938-1:2019 testing?
Made by our specialist brand Testing Machines Inc, our tissue ball burst tester is a precision testing instrument which automatically determines the burst strength of your tissue paper samples.
All of your favorite testing parameters: test speed, peak burst strength; they’re all there and selectable with an easy to use software program. The system incorporates high resolution, low capacity load cells with accuracies better than +/-0.5% down to 1/1000th of the load cell capacity for accuracy and simplicity of operation.
While undertaking tissue paper testing you can set parameters such as test speed and peak burst strength. In addition to tissue burst, other force measurements such as tensile or compression strength can be performed with the proper testing grips and fixtures.
The machine is developed to test specifically for TAPPI T-570, ISO 13938-1:2019 and ISO 12625-11.
