préface
OIN (Organisation internationale de normalisation) est une alliance mondiale d'organismes de normalisation nationaux (Comités membres de l'ISO). L'élaboration de normes internationales est généralement réalisée par l'intermédiaire de comités techniques ISO.. Chaque institution membre intéressée par un sujet pour lequel un comité technique a été créé a le droit d'être représentée au sein de ce comité.. Les organisations internationales gouvernementales et non gouvernementales en liaison avec l'ISO sont également impliquées dans ces travaux..

Draft international standards adopted by technical committees are circulated to member bodies for approval before being accepted as international standards by the ISO Council. They are approved under the ISO process, which requires at least 75 per cent approval from voting member bodies.

Norme internationale ISO 7384 a été développé par le comité technique ISO/TC 156, Corrosion des métaux et alliages.

Users should note that, unless otherwise noted, all international standards are revised from time to time, and unless otherwise noted, any reference herein to any other international standard is meant to be the latest version.

7384-1986 Artificial Atmospheric Corrosion Tests – General Requirements

1 Scope and domain of application
This standard specifies the general requirements for specimens, equipment and procedures for artificial atmospheric corrosion tests. It is applicable to metals and alloys with or without permanent or temporary corrosion protection.

The requirements set forth in this standard are intended to be applied to other international standards involving artificial atmosphere corrosion testing and accelerated test methods and construction of new chambers.

3 Définition
For the purposes of this international standard, the following definitions apply.

Corrosion tests in Artificial atmosphere: Laboratory tests performed in air with or without permanent or temporary corrosion protection for the presence of aggravating factors affecting the corrosion of metallic materials and alloys.

Note – Corrosion tests in artificial atmospheres attempt to reproduce corrosion effects under working conditions, such as atmospheric or other environments.
