TAPPI T 838
TAPPI T838 is a standard test procedure for the edgewise compressive strength of corrugated fiberboard by the short column procedure. Measures the strength of corrugated board to resist crushing forces applied against its side, an important test for corrugated packaging. The maximum load that a sample can withstand without breaking gives the manufacturer some important information about the strength of packaging material. TAPPI T838 is the most commonly used in the paper and packaging industries to evaluate the quality of boards and predict box performance. Presto Laboratories provides state-of-the-art testing solutions to enable the manufacturers to evaluate the strength of corrugated board accurately as per the TAPPI T838 requirement.
Significance
Compressive strength is a key factor in the durability of stacking shipping cartons and transport packages made from corrugated fiberboard. This is because if the board structures are weak, package deformation, collapse, and product damage can occur in warehousing and distribution. TAPPI T838 can be used by manufacturers to ensure the quality of the material and compare the different grades of board and to help ensure uniformity in the production process. The test results are used as assistance in packaging design, quality assurance, and materials development. Regular testing also helps industries reduce packaging failures and improve the overall performance of corrugated containers used throughout the supply chain. Scope The edgewise compressive strength of corrugated fiberboard is determined by the short specimen compression method as described in TAPPI T838. It describes the method of specimen preparation, conditioning, and testing in a controlled laboratory. It can be used for different corrugated board configurations in packaging products. The method can be used to consistently and repeatably assess material strength and to compare the performance of corrugated packaging materials.
