Resumen:
The document 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 x internal diameter, but not less than 10,0 mm; - minimum length of core: 10 x internal diamete, but not less than 1 000 mm.
