EN ISO 3037 Corrugated Cardboard, Determination of Edge Crush Resistance (Waxless Edge Method)

EUROLAB laboratory provides testing and compliance services within the scope of EN ISO 3037 standard. EN ISO 3037 specifies the wax-free edge method for determining the edge crush resistance of corrugated board. Applies to all corrugated board grades.

EN ISO 3037 Corrugated Cardboard, Determination of Edge Crush Resistance (Waxless Edge Method)

Various methods are used to determine edge crush resistance in different parts of the world.

These can be divided into three groups as follows:

  • A carefully cut rectangular test piece is tested without any special treatment or modification;
  • The edges of the forcefully applied test piece are waxed so that the test result is not affected by “edge effects”;
  • Those where the test piece edges are not waxed, but such that the length is significantly reduced at a point in the middle of the loaded edges to cause the shape of the test piece to occur away from these edges.

The methods may not give the same numerical results, but it can be shown that many of them can be used to estimate the top-down compressive strength that would be obtained when the sheet was properly converted into a transport package.

Other methods can be used for other purposes, especially when the purpose of testing is to examine the core structural properties of the package. There are methods available for calculating the edge crush strength from the compressive strength of the component papers.
