7384-1986 Artificial Atmospheric Corrosion TestsGeneral Requirements

prefaţă
ISO (Organizația Internațională pentru Standardizare) este o alianță globală a organismelor naționale de standardizare (organismele membre ISO). Elaborarea standardelor internaționale se realizează de obicei prin intermediul comitetelor tehnice ISO. Fiecare instituție membră interesată de un subiect pe care a fost înființat un comitet tehnic are dreptul de a fi reprezentată în respectivul comitet. Organizațiile internaționale guvernamentale și neguvernamentale care au legătură cu ISO sunt, de asemenea, implicate în această activitate.

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.

Standardul internațional ISO 7384 a fost dezvoltat de Comitetul Tehnic 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.

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 Definiție
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.

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