ISO 3037 - Corrugated fibreboard - Determination of edgewise compressive strength (unwaxed edge method)
ISO 3037 is a revised technical standard that describes a specific method for determining the edgewise compressive strength of corrugated fibreboard. This standard applies to various flutes of single, double, and triple wall corrugated board, in situations where there is no buckling or tilting during the measurement.
The testing process according to this standard is done without the use of wax coating, a feature that distinguishes this method from some others that may use wax as a stabilizer or as a means of modifying the strength of the board. This approach provides a more natural evaluation of the strength of corrugated fibreboard, which may be more relevant for certain applications where wax coating is not used.
The edgewise compressive strength (Edge Crush Test, or ECT) is a measure of the maximum force that a specimen of corrugated fibreboard can withstand without showing signs of crushing. The force is measured in length units, typically expressed in kilonewtons per meter (kN/m).
ISO 3037 is a useful standard for industries working with corrugated fibreboard, such as the packaging and logistics industry, as it provides a standardized method for evaluating the strength of their products. It is also important to note that this standard can be applied to samples taken from corrugated boxes and other processed products, offering great flexibility in its use.
In summary, ISO 3037 provides a methodology for testing the edgewise compressive strength of corrugated fibreboard. Implementing this standard ensures better quality and greater consistency in the evaluation of corrugated fibreboard performance.
