BS ISO 11093-8:2017 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.Cross References:ISO 11093-3:1994ISO 11093-2:1994ISO 11093-1:1994 ISO 11093-7:2011 Ed 2All current amendments available at time of purchase are included with the purchase of this document.
