3 Terms and definitions
The following terms and definitions defined in GB/T 1800.1 apply to this document.
3.1 Size
A numerical value that expresses a linear dimension value in a specific unit.
3.1.1 Basicsize
Nominalsize
By applying the upper and lower deviations (3.2), the size of the limit size (3.1.3) can be calculated.
Note. The basic size can be integer or decimal. Such as 32, 15, 8.75, 0.5, etc.
3.1.2 Actualsize
The size of the element obtained by measurement.
3.1.3 Limitsofsize
The two extremes of the allowable size of the size element.
Note. The actual size (3.1.2) is located in it, and it can also reach the limit size.
