ISO 3037
Edgewise crush resistance of corrugated fiberboard to an internationally recognized standard—ISO 3037. The Edge Crush Test (ECT) is also referred to as the test of the maximum force a piece of corrugated board can withstand when pushing against it at right angles to the flutes. The edge crush test is commonly used in the packing industry because it's closely related to the stacking strength of corrugated boxes. High-strength corrugated boards provide protection for products when stored, warehoused, and in transit. Presto Laboratories provides cutting-edge testing services and can assist manufacturers in determining the compression strength of corrugated packaging materials as needed under ISO 3037 standards.
Significance
Corrugated board resistance to edge crush is one of the most critical corrugated board quality parameters. Poor crush strength packaging can cause buckling or collapsing under stacking loads, causing damage to the product and higher logistics costs. ISO 3037 assists manufacturers in measuring the load-bearing capacity of corrugated fiberboard or comparing the performance of different board grades. Test data are used for packaging design, choice of packaging materials, packaging quality control, and packaging production consistency. By regularly testing packaging edges for potential issues, industries can also reduce the risk of packaging failures and ensure packaging integrity throughout the distribution chain. Scope ISO 3037 covers the determination of edgewise crush resistance of corrugated fiberboard under controlled compression conditions. The standard specifies procedures for specimen preparation, conditioning, and testing to obtain accurate and repeatable results. It is applicable to various corrugated board constructions used in packaging applications. The method provides a standardized approach for evaluating material strength and comparing packaging performance in laboratory environments.
