INTRODUCTION Terms used in this manual Nominal means the rated (design) size or magnitude of a part to be measured. Standard means the quantitative requirement for dimension of a part, clearance between parts and performance. This is given in a form of tolerance. Therfore, the values shown are not in agreement with the design values. Limit means that, if this value is reached, the part must be repaired or replaced with a new part.
