مقدمة
ايزو (المنظمة الدولية للمقاييس) هو تحالف عالمي لهيئات المعايير الوطنية (الهيئات الأعضاء في منظمة الأيزو). عادة ما يتم تطوير المعايير الدولية من خلال اللجان الفنية ISO. يحق لكل مؤسسة عضو مهتمة بموضوع تم تشكيل لجنة فنية له أن تكون ممثلة في تلك اللجنة. وتشارك أيضًا في هذا العمل المنظمات الحكومية الدولية وغير الحكومية المتعاونة مع ISO.

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.

المعيار الدولي ISO 7384 تم تطويره من قبل اللجنة الفنية ISO/TC 156, Corrosion of Metals and Alloys.

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 اختبارات التآكل الجوي الاصطناعي – المتطلبات العامة

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 تعريف
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.

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