ISO 11093:2017 Paper and board – Testing of cores – Part 8: Determination of natural frequency and flexural modulus by experimental modal analysis
CDN $115.00
Description
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 √ó internal diameter or not less than 2,0 mm;
– minimum length of core:
8 √ó internal diameter.
NOTE For the determination of the flexural modulus by the three-point method, see ISO 11093‚Äë7.
