The part of ISO 3547 specifies, following ISO 12301, the checking of the inside diameter of wrapped bushes (see ISO 3547-2:2006, method C) and describes the necessary checking methods and measuring equipment. Wrapped bushes in the free condition are flexible, but after insertion they adapt largely to the shape of the housing bore due to the interference between the outside diameter of the bush and the housing bore. NOTE 1 All dimensions in this part of ISO 3547 are given in millimetres except where otherwise noted/designated. NOTE 2 The dimensions and tolerances of wrapped bushes are given in ISO 3547-1. NOTE 3 Checking of the wall thickness is the subject of ISO 3547-7. NOTE 4 Checking of the outside diameter of wrapped bushes is the subject of ISO 3547-5. 2
