Paper and board - Testing of cores - Part 8: Determination of natural frequency and flexural modulus by experimental modal analysis (ISO 11093-8:2017)More info
This document 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.
