3 Terms and definitions
This standard applies the following terms with respective definitions:
3.1 the nominal size of the part (casting): the Size specified on the detail drawing (casting).
3.2 the average size of items: Size of the part corresponding to the middle of the field of his admission.
(Changed edition, Rev. N 2).
3.3 dimensions of castings: a Collection of casting dimensions, characterized by similar structural and technological conditions for the formation of their accuracy.
Dimensions 1 — dimensions of the casting formed one part of a mold or a core.
The dimensions of the 2 sizes of castings and formed by two proformae or the drag and rod (including the dimensions of the facing plane of the connector casting or crossing it).
Dimensions 3 — dimensions of the castings formed by three or more parts of the mold, several bars, or moving form elements, and the thickness of the walls, which is the closing link in two sizes.
3.4 actual size of casting: the Actual size is measured point-to-point tool.

3.6 General tolerance item casting: a Comprehensive tolerance, including tolerance of size from the surface to the base and is independently assigned tolerances of form and arrangement of normalized surface area.
3.7 surface roughness: a Set of recurring irregularities of small magnitude (of asperities).
The baseline for determination of roughness parameters is the average line of the white surface. Accepted symbols: (mm) — arithmetical mean deviation of the white surfaces (µm) is the height of the roughness (ten-point).
3.8 neravnomernosti surface: a Set of recurring irregularities average value (metoprolola), i.e. surface irregularities, a step higher than the base length, which measures the roughness of the surface.
The baseline for determining values of parameters of neravnomernosti is the average line profile of a surface.
The basic length for measuring neravnomernosti surfaces of castings shall be equal to 4−10 sampling lengths for the measurement of roughness, but at least five steps of neravnomernosti and not more than 100 mm.
