GB/T 22906.6-2008 "Testing of cores - Part 6: Determination of bending strength by three-point method" specifies the method for determining the bending strength of cylindrical paper cores using the three-point method. It is applicable to paper cores with an inner diameter of 50mm to 300mm, a wall thickness of ≥5mm, and a length of ≥1100mm. After conditioning the specimens under specified temperature and humidity, the bending strength is calculated based on the breaking load measured via three-point loading. The standard defines the loading speed, span, and calculation of results, and is used to evaluate the bending resistance of paper cores.
