Description (English):

ISO 9226:2012 specifies methods which can be used for the determination of corrosion rate with standard specimens. The values obtained from the measurements (corrosion rates for the first year of exposure) are intended to be used as classification criteria for the evaluation of atmospheric corrosivity according to ISO 9223. They can also be used for informative evaluation of atmospheric corrosivity beyond the scope of ISO 9223.

Abstract

Overview

ISO 9226:2012 is an essential international standard published by the International Organization for Standardization (ISO) that specifies methods for determining the corrosion rate of standard metal and alloy specimens. Focused on atmospheric conditions, the standard enables the evaluation of atmospheric corrosivity by measuring corrosion rates on standardized test specimens exposed to the environment over one year. These corrosion rates provide crucial classification criteria in accordance with ISO 9223 for assessing the corrosivity of various atmospheres.

This standardized method offers a practical, economical approach to characterize corrosion levels at different locations or industrial sites by using standard specimens made from typical structural metals. The primary metals covered include steel, zinc, copper, and aluminium, with carefully controlled specimen preparation, exposure, and evaluation procedures.

Key Topics

Scope and Purpose ISO 9226:2012 specifies test methods to determine corrosion rates based on mass loss of metal specimens after exposure to atmospheric conditions. The resulting data categorize atmospheric corrosivity following ISO 9223, and can also inform on corrosivity beyond ISO 9223’s scope.
Standard Specimens Specimens are flat plates, typically 100 mm × 150 mm and about 1 mm thick, composed of:
- Carbon steel (unalloyed, Cu 0.03%-0.10%, P
