Scope
This part of GB/T 22906 specifies the method for determining the elastic modulus of paper cores, which should meet the following conditions:
——Inner diameter: 50 mm to 350 mm;
——Minimum wall thickness: 0.02 times the inner diameter or not less than 2.0 mm;
——Minimum length: 8 times the inner diameter or not less than 1,000 mm.
This part is applicable to the determination of the elastic modulus of paper cores.
