Introduction

Established in this standard the terms are arranged in a systematic manner, reflecting the system concepts in the area of secondary ferrous metals.

For each concept has a single standardized term.

Deprecated the use of synonymous terms is given in parentheses after standardized term and is marked with the note «RNC.».

Enclosed in parentheses the part of term can be omitted when using the term in the standardization documents, while not part of the parentheses part of the term represents its short form.

Given the definition, you can optionally change by entering into derivative signs, by revealing the meaning of the terms used, indicating the objects included in the volume defined concepts. Changes must not violate the scope and content of concepts defined in this standard.

The definition of the term, containing all necessary and sufficient conditions of concepts are not given and instead marked with a dash.

Standardized terms in bold, their short forms — light, and synonyms in italics.
