This system captures both bursting strength and distension at burst. It applies hydraulic pressure through a rubber diaphragm until the specimen fails, so you can record the burst pressure and the material’s expansion at rupture in one test. That makes it well suited for woven fabrics, knitted fabrics, nonwovens, paper, and board materials.

Those two results answer different parts of the same performance question. Bursting strength shows how much pressure the sample can withstand, while distension at burst shows how far it expands before failure under multidirectional stress. For labs that need tighter control over burst height measurement, this tester is specified at ±1 mm accuracy when burst height is up to 70 mm, and automatic burst detection helps support consistent reporting.
