TAPPI T 838 CM 2012

TAPPI T 838 CM 2012 specifies the edge crush test using a neckdown specimen configuration for corrugated fiberboard.

TAPPI T 838 CM 2012 provides a complete procedure for determining the edgewise compressive strength of single-, double-, and triple-wall corrugated fiberboard using a narrowed, non-reinforced loading edge configuration. This technical method covers apparatus requirements, specimen preparation, safety, sampling, conditioning, testing, reporting, precision, and related methods. It is intended for comparing the edgewise compressive strength of similar corrugated board materials and material combinations, with results reported using maximum load, valid failure determinations, average performance, and variability measurements.

Application Scope: Suitable for paperboard packaging laboratories, corrugated fiberboard manufacturers, quality assurance programs, research facilities, and technical users evaluating edge crush resistance and compressive performance.
