GB/T 6548-2011 Determination of adhesive strength of corrugated fibreboard specifies the method for determining the adhesive strength of corrugated fibreboard, which is suitable for the evaluation of various corrugated fibreboard. The standard evaluates the adhesive strength by measuring the maximum force required for separation between the layers of corrugated fibreboard. During the test, the sample is placed in a disbonding rack, and pressure is applied at a specified speed using a compression tester to record the maximum separation force. The standard describes in detail the instrument equipment, sample preparation and test steps to ensure the accuracy of the measurement results. The test report should include the standard number, sample information, test conditions and results, etc.
