scope:
This part of ISO 11093 specifies a method for the determination of the flexural modulus by using experimentally measured natural frequencies in the free-free mode of transverse vibration of cylindrical paper and board cores, which meet the following criteria:
- internal diameter: 50 mm to 350 mm;
- minimum wall thickness: 0,02 × internal diameter or not less than 2,0 mm;
- minimum length of core: 8 × internal diameter.
NOTE For the determination of the flexural modulus by the three-point method, see ISO 11093-7.N1)
N1) National footnote: And DIN ISO 11093-7 (see National Annex NA).
