TAPPI T839 Edge Compression Test (ECT) – Clamp Method

Testing Standard:

TAPPI T839 Edgewise Compressive Strength of Corrugated Fiberboard Using the Clamp Method (Short Column Test)

Standard Number
TAPPI T839

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

Overview:

TAPPI T839 Test Method details the method of obtaining the maximum compression strength measurement perpendicular to the flute axis of corrugated fiberboard. TAPPI T839 utilizes a spring support clamp fixture to reduce edge rolling of the material during testing. Purple Diamond Testing offers TAPPI T839 Edgewise Compressive Strength of Corrugated Fiberboard Clamp Method (Short Column Test) as part of our packaging compliance and validation services.

Rationale:

TAPPI T839 – Edgewise Compressive Strength of Corrugated Fiberboard Clamp Method (Short Column Test). 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. Utilizing a clamp fixture reduces the potential of edge rolling of the linerboards during testing. The max force to cause compressive failure is recorded as the ECT value.
