The purpose of this European Standard is:
To define the terms in the ferrous products heat treatment vocabulary.
These terms are divided into a main part and a complementary section
— the main part gives an alphabetical list of the terms with their definitions and, where appropriate, comments. Definitions of foreign terms for which the language in question has no equivalents are given at the end of the main part under their reference number;
— the complementary section comprises the definitions of terms necessary to understand the main part.
NOTE The comments are printed in italics in order to differentiate them from the definitions.
Any term defined in the main part of this European Standard and used elsewhere in a definition or a comment is printed in capital letters.
The reference numbers given with each term are identical in all the versions and correspond to the French alphabetical order. In order to avoid any confusion, the numbers of the terms in the annex are preceded by the letter A.
To facilitate translations using the tables of equivalent terms.
