Appita/AS 1301.444s

Introducing Appita/AS 1301.444s – Industrial Physics

The Appita/AS 1301.444s method is an edgewise crush resistance test designed to inspect the strength of pulp and paper samples using the unwaxed edge method.  

This is an Australian / New Zealand edgewise crush testing standard brought to you by Appita, a not-for-profit industry association that supports the advancement of the pulp, paper packaging and bioproducts industries. 

What is an edgewise crush resistance test?

As one of the most common ways to test the peak load of materials like paper, board and corrugated cardboard can handle, edgewise crush testing – or edge crush testing (ECT) as it’s sometimes known – is a key factor for any good corrugated QA process. 

Also known as ECT, this technique is very handy for working out the overall strength and durability of any packaging made from corrugated materials material. The edge crush test is a method of determining the cross-direction force needed to crush a sample of corrugated board to the point of failure. 

Edgewise crush resistance testing approaches

There are three primary methods of edgewise crush resistance testing in use across the world: 

1. Edgewise crush resistance testing with rectangular test pieces cut without any special treatment or modification. As is the case with Appita/AS 1301.444s. 

1. Edgewise crush resistance testing in which the edges of the test pieces – where the force is applied – are waxed.  

1. Edgewise crush resistance testing in which the test piece edges are not waxed. However, the shape of the test piece is such that the length is substantially reduced at a point between the loaded edges in order to induce a failure to occur, away from the edges.
