3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
For further terms and definitions, see also ISO 286-1. It should be noted that some of the terms are defined in a more restricted sense than in common usage.
3.1
shaft
external feature of a worlcpiece, including features wNch are not cylindrical
3.2
hole
internal feature of a workpiece, including features which are not cylindrical
3.3
size
number, expressing in a particular unit, the numerical value of a linear dimension
3.3.1
basic size
nominal size
size from which the limits of size are derived by the application of the upper and lower deviations
NOTE The basic size can be a whole number or a decimal number, e.g. 32:15; 8,75:0,5 etc.
3.3.2
actual size
size of a feature, obtained by measurements
3.3-3
limits of size
the two extreme permissible sizes of a feature, between which the actual size should lie, the limits of size being included
3.3.3.1
maximum limit of size
greatest permissible size of a feature
3.3.3.2
minimum limit of size
smallest permissible size of a feature
3.4
deviation
algebraic difference between a size (actual size, limit of size, etc.) and the corresponding basic size
NOTE Symbols for shaft deviations are lower case letters (es, ei) and symbols for hole deviations are upper case letters(ES, Er).
3.4.1
limit deviations
upper deviation and lower deviation
3.4.1.1
upper deviationES, es
algebraic difference between the maximum limit of size and the corresponding basic size
3.4.1.2
lower deviationEl , ei
algebraic difference between the minimum limit of size and the corresponding basic size
3.5
size tolerance
difference between the maximum limit of size and the minimum limit of size,i.e. the ditference between the upperdeviation and the lower deviation
NOTE The tolerance is an absolute value without sign.
