Paper and board. Testing of cores - Determination of flexural modulus by the three-point method Ingestion-build-67170 limited or specialized usage or1 Scope This part of ISO 11093 specifies a method for the determination, by the three point method, of the flexural modulus of cylindrical paper and board cores which meet the following criteria: internal diameter: 50 mm to 350 mm; minimum wall thickness: 0,05 internal diameter, but not less than 10,0 mm; minimum length of core: 10 internal diameter, but not less than 1 000 mm. If the flexural modulus has to be used for the calculation of a paper
