Scope

This part of GB/T 22906 specifies the method for the determination of the elastic modulus of the paper core. The paper core should meet the following conditions: —Inner diameter: 50 mm to 350 mm; —Minimum wall thickness: 0.02×inner diameter or not less than 2.0 mm; — Minimum length: 8 x inner diameter or not less than 1000 mm. This section applies to the determination of the elastic modulus of the paper core.
