This part of GB/T 12613 specifies the test data of the outer diameter and inner diameter of the shaft sleeve made of single-layer and multi-layer material rolls, and also specifies the inspection method and marking method. Since the measurement of the wall thickness of the shaft sleeve is carried out in a free state, there is no test requirement specified in the figure (according to GB/T 12613.5 and GB/T 12613.6).
