Paper and board. Testing of cores - Determination of bending strength by the three-point method Ingestion-build-48183 which are influenced by environmental1 Scope This part of ISO 11093 specifies a three point method for the determination of the bending strength of cylindrical board cores which meet the following criteria: internal diameter: 50 mm to 300 mm; minimum wall thickness: 5 mm; minimum test length of core (span): 1 100 mm.
