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 core's natural frequency, ISO 11093‑8[2] applies instead of this International Standard.N1)
N1) National footnote: DIN ISO 11093-8 applies accordingly (see National Annex NA).
