Scope

This part of GB/T 22906 specifies the test method for determining the natural frequency and elastic modulus of the paper core by using a transverse vibration test model with two free ends. This section applies to paper cores with an inner diameter of 50 mm to 350 mm, a minimum wall thickness of 0.02 times the inner diameter or not less than 2.0 mm, and a minimum length of 8 times the inner diameter.
