TAPPI T 566 om-08 provides a standardized procedure for measuring the bending resistance of flexible paper using a Taber-type tester in the 0 to 10 Taber stiffness unit configuration. The six-page official method covers applicable documents, terminology, apparatus preparation, calibration, sampling, conditioning, specimen preparation, testing procedures, calculations, reporting requirements, precision, and related methods.
This digital PDF is intended for paper manufacturers, testing laboratories, quality professionals, engineers, and technical teams evaluating paper performance in wrapping, printing, copying, document handling, and other applications where stiffness is important.
Application Scope: Use for laboratory testing and quality control of low-grammage or highly flexible paper when determining bending moment, resistance to bending, and Taber stiffness in the 0 to 10 unit range. Do not use this method where TAPPI T 489 is specifically required.
