If the reference standard is cancelled without replacement, then the situation in which the given link applies to the extent that does not affect this link.

3 Terms and definitions

This standard applies the terminology according to GOST 32597, as well as the following terms with respective definitions:

3.1 rod: a Solid product of uniform cross section throughout its length, in the form of a circle, square, regular polygons, supplied in straight lengths or rolled in the Bay.

3.2 extruded bars and rods: a Solid product of uniform cross-section produced by continuous extrusion rotation (the process of «Conform») supplied in the form of direct cuts or wound on drums.

3.3 Bay: Cut products, rolled into a series of continuous turns.

3.4 measuring length: the Product of a certain length, specified in the order, straight leg, or in the Bay.

3.5 times the length: the Period of integral multiple of the number of core length with an allowance for cutting and a tolerance on the overall length.

3.6 stratification: the discontinuity of metal, oriented along the direction of deformation.

4 Assortment

4.1 the Diameter of a drawn bar and limit deviations of the diameter must match the values specified in table 1.


Table 1

4.2 the diameter of the extruded rods and the tolerances for diameter shall conform to the values specified in table 2.


Table 2
