1.1 This method describes procedures for determining the edgewise compressive strength (ECT), perpendicular to the axis of the flutes, of a short column of single-, double-, or triple-wall corrugated fiberboard ( 1 ).
The edge crush test (ECT) to DIN EN ISO 3037 or TAPPI T 811 provides information on the strength of corrugated cardboard with flutes positioned vertically. It is important that force application to the specimen is exactly perpendicular during these tests.
What do we know about the relation of ECT to properties of the linerboard and medium? Koning reported long ago that ECT was strongly related to the sum of the ring crush values of the component facings and the medium with allowances for the additional length of medium in a unit length of combined
We publish 4 types of TAPPI Standards: TAPPI Test Methods are testing procedures. We use 6 different categories for our Test Methods: Official Method, Provisional Method, Standard Practice, Classical Method, Withdrawn Method, and Useful Method (UM). Learn more about these 6 categories.
The Edge Compression Test method or ECT describes procedures for determining the edgewise compressive strength, parallel to the flutes, of a short column of single-, double-, or triple-wall corrugated fiberboard (constant strain rate, or constant load rate).
