A.1 Dimensioning for unequal wall thickness

Describes the checking methods and measuring equipment used for measuring the total wall thickness of thin walled half bearings and thin walled bushes in the finished state. Coverage includes purpose of checking, checking methods, checking of measuring equipment, and requirements for measuring equipment for the contact method. Also gives annexes, tables, diagrams, and symbols and units.
