BS EN ISO 13938-1:2019 pdf free download.Textiles – Bursting properties of fabrics.
BS EN ISO 13938-1:2019 describes a hydraulic method for the determination of bursting strength and bursting distension of textile fabrics. In this document, a hydraulic pressure is applied using a constant rate of pumping device.
From the available data, there appears to be no significant difference in the bursting strength results achieved using hydraulic or pneumatic burst testers, for pressures up to 800 kPa. This pressure range covers the majority of performance levels expected of general apparel, For speciality textiles requiring high bursting pressures, the hydraulic apparatus is more suitable.

7 Atmospheres for conditioning and testing
The atmospheres for preconditioning, conditioning and testing shall be as specified in IS0 139 Preconditioning and conditioning are not required for wet tests.
Procedure
8.1 Prior to testing the sample shall be conditioned in the relaxed state in accordance with Clause 7. During conditioning and testing maintain the test specimens in the atmosphere for conditioning and testing in accordance with Clause 7.
