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

SKU: c6129d144694 Category:

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.
