TAPPI T811 Edge Compression Test (ECT) Corrugated

Testing Standard:

TAPPI T811 Edgewise Compressive Strength of Corrugated Fiberboard (Short Column Test)

Standard Number
TAPPI T811

Standard Title
Edgewise Compressive Strength of Corrugated Fiberboard (Short Column Test), Test Method

Overview:

TAPPI T811 Test Method details the method of obtaining the maximum compression strength measurement perpendicular to the flute axis of corrugated fiberboard. TAPPI T811 utilizes wax dipping of the sample’s vertical edges prior to testing. This property is essential when designing packaging as it directly relates to the compressive resistance of a box. Purple Diamond Testing offers TAPPI T811 Edgewise Compressive Strength of Corrugated Fiberboard (ECT) as part of our packaging compliance and validation services.

Rationale:

TAPPI T811 – Edgewise Compressive Strength of Corrugated Fiberboard (ECT). Data collected can be used along with flexural stiffness and box dimensions to accurately predict the overall top-to-bottom compression strength of corrugated boxes. This is achieved by first sealing the vertical edges in paraffin wax prior to testing. The samples are supported in the test machine using metal guide blocks and the max force to cause compressive failure is recorded as the ECT value.
