ISO 5635-3 Edgewise Crush Test

The ISO 5635-3 edgewise crush test is a fundamental standard used in the packaging industry to measure the resistance of paper and cardboard materials to edge compression loads. This test plays a crucial role in ensuring that packages meet performance requirements, particularly for products that require protection during transportation.

The test method involves applying a gradually increasing load on an edge of a specimen cut from a sheet or roll of material until it crushes under the specified loading conditions. The standard specifies the dimensions and preparation methods for specimens as well as the procedure to ensure accurate testing results.

Understanding the crush resistance of paper and cardboard is essential for several reasons:

To prevent damage to contents during transportation
To protect against environmental factors such as moisture or temperature changes
To ensure compliance with industry standards and regulations

Failure to meet the crush resistance requirements can lead to increased product returns, damaged goods, and potential legal issues. By conducting this test, manufacturers can validate the integrity of their packaging solutions and ensure they are fit for purpose.

The ISO 5635-3 standard is widely recognized in the industry as a reliable method for assessing crush resistance. Compliance with these standards ensures that products meet safety requirements and perform effectively under real-world conditions.

For quality managers, compliance officers, R&D engineers, and procurement professionals responsible for packaging design and development, this test offers valuable insights into material performance. It provides crucial data on the strength of paper and cardboard materials, which can be used to optimize packaging designs and improve overall product protection.

Why It Matters

The ISO 5635-3 edgewise crush test is not just a technical requirement; it also has significant implications for the environment, sustainability efforts, and business operations. By ensuring that paper and cardboard packaging meets the necessary crush resistance standards, businesses can contribute positively to environmental goals.

Compliance with ISO 5635-3 helps reduce waste by promoting more efficient use of materials and reducing the likelihood of product damage during transportation. This, in turn, leads to lower resource consumption and energy usage across the supply chain.

Reduces material wastage due to improper crush resistance
Promotes sustainable packaging design by encouraging the use of materials that meet performance requirements
Aids in meeting regulatory and customer expectations for eco-friendly products
