Specifies the methods for checking the measuring equipment and gauging tools used when measuring peripheral length.
This International Standard specifies methods of checking the measuring equipment and gauging tools necessary for measuring the peripheral length (or nip or crush) of thin-walled half-bearings.
Thin-walled half-bearings are flexible and, in the free condition, do not conform to a cylindrical profile. This is one reason why the peripheral length of the half-bearings can only be measured under a constraining load by use of specialized measuring equipment.
Measuring equipment different from that illustrated in this International Standard can be used, providing the measuring accuracy of the equipment is consistent with the specifications given in clause 17.
This International Standard does not include measurement of the joint face taper.
It applies to thin-walled half-bearings, the specifications of which are given in ISO 3548 and ISO 6864.
