Key Features and Benefits

• Standard Number: BS ISO 13821:2020
• ISBN: 978 0 539 12567 2
• Status: Standard

The BS ISO 13821:2020 standard is recognized globally for its precision and reliability. By adhering to this standard, companies can ensure that their corrugated fibreboard products meet international quality benchmarks, thereby enhancing their marketability and consumer trust.

Understanding the Waxed Edge Method

The waxed edge method is a specialized technique used to measure the edgewise crush resistance of corrugated fibreboard. This method involves applying a wax coating to the edges of the test specimen to prevent edge damage during testing, ensuring that the results accurately reflect the material's inherent strength.

Why Edgewise Crush Resistance Matters

Edgewise crush resistance is a critical parameter in the packaging industry. It determines the ability of corrugated fibreboard to resist compressive forces that occur during stacking and shipping. High edgewise crush resistance indicates that the material can maintain its structural integrity under pressure, reducing the risk of product damage and loss.

BS ISO 13821:2020

This standard BS ISO 13821:2020 Corrugated fibreboard. Determination of edgewise crush resistance. Waxed edge method is classified in these ICS categories:

• 85.060 Paper and board

This document specifies a method for the determination of the edgewise crush resistance of corrugated fibreboard. The force is applied in the direction of the flute axis.

This method is applicable to single-wall (double-faced), double-wall, and triple-wall corrugated fibreboard. It may also be used to test samples taken from corrugated cases and other converted products.

While the method is applicable to waxed corrugated fibreboard, care must be taken that the heat used in the waxing step does not affect the corrugated structure. This is controlled by observing that failure during the test still occurs away from the loaded edges.
