BS EN ISO 3303-2-2020 Rubber- or plastics-coated fabrics – Determination of bursting strength Part 2: Hydraulic method.
This document specifies a method for the determination of the bursting strength of rubber – or plastics
– coated fabrics, using one of two types of diaphragm bursting tester, designated type A and B, both operated by hydraulic pressure.
The type A test machine is applicable to materials having bursting strengths ranging from 350 kPa to 5 500 kPa and the type B test machine is applicable to materials of bursting strengths ranging from 70 kPa to 1400 kPa.

A test piece is securely clamped around its edges between an upper and lower clamp. A diaphragm
fitted beneath the lower clamp is gradually stretched into a dome by forcing fluid at a constant rate into
a chamber under the diaphragm, thus causing it to make contact with, and apply pressure to, the test
piece. The pressure of the fluid and the height of the dome at failure of the test piece are recorded.
5 Apparatus and reagents
5.1 Testing machine, of type A (see 5.1.1) or type B (see £12).
5.2 Pressure-measuring system to measure bursting strength, giving a rate of response to the rising hydraulic pressure which is such that the indicated maximum pressure is within3 % of the true peak pressure.
5.3 Equipment in which the test pieces can be immersed in water prior to wet testing.
5.4 Distilled or deionized water, for preparing the wet test pieces.
5.5 Wetting agent or surfactant.
5.6 Blotting paper, two sheets required for the test on wet test pieces.BS EN ISO 3303-2 pdf download.
