TAPPI T403

Introducing TAPPI T403 – Industrial Physics

TAPPI T403 is a global TAPPI standard method that’s used to measure the maximum bursting strength of paper and paper products. 

Bursting strength is widely used as a measure of resistance to rupture in many kinds of paper. Burst tests are relatively easy and inexpensive to perform and simulate the pressures your products will encounter in the real world, helping you to predict how they’ll perform. 

You can use TAPPI T403 burst testing to inspect the bursting strength of newsprint, bag paper, fine paper, packaging paper, and printing papers. It’s a TAPPI test that’s designed for burst testing flat sheets of paper up to 0.6mm thick with a bursting strength of 50 kPa up to 1200 kPa (7 psi up to 175 psi).   

TAPPI T403 is not intended for use in testing corrugated, fiberboard, linerboard, or hardboards that tend to cut the thin rubber diaphragm of the bursting tester. For testing paperboard and linerboard, see TAPPI T 807 Bursting Strength of Paperboard and Linerboard; for testing corrugated and solid fiberboard, see TAPPI T 810 Bursting Strength of Corrugated and Solid Fiberboard. 

The TAPPI T403 burst testing method

First up you’ll need to secure your bursting strength test specimen between annular clamps. Your test sample is then subjected to increasing pressure using a rubber diaphragm, expanded by hydraulic pressure at a controlled rate, until it ruptures. The maximum pressure reading up to the rupture point is recorded as the bursting strength.

So, how can Industrial Physics improve your TAPPI T403 burst testing? 

Burst Tester 13-56 

This digital mullen burst tester will measure the strength and resilience of sheet materials by burst testing for real life failures such as punctures and rupture.

It uses hydraulic pressurization of a membrane against a clamped, film, or sheet sample. This burst testing approach produces a multi-directional stress on the material to failure – which is the burst strength.
 

With state-of-the-art electronics and user interface, our new 13-56 burst tester is easier to use than ever before and makes light work of TAPPI T 403 testing.
