Note — When using this standard appropriate to test the effect of reference standards for the sign «National standards» drawn up as of January 1 of the current year and related information signs, published in the current year. If the reference standard is replaced (changed), when using this standard should be guided by replacing (amended) standard. 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 Bay: Cut product wound into a series of continuous turns right not mixed up in rows, with no sharp bends.

3.3 measuring length: Specific length of the product, specified in the order, straight leg, or in the Bay.

3.4 times the length: the Length of a whole multiple of the number of core length with an allowance for cutting and a tolerance on the overall length.

3.5 stress corrosion cracking: Destructive process of the joint corrosion and deformation of the metal due to residual or applied stresses.

3.6 residual tensile stress: the Stress remaining in the metal by plastic deformation.
