Abstract

In corrosion engineering large efforts have been made to develop quantitative accelerated corrosion tests for the purpose of product qualification. As a result of this work a broad spectrum of methods now exists of which some are also available as international standards.

The new kind of accelerated corrosion tests offer many new possibilities. However, to identify the most relevant method for one specific application requires knowledge that usually goes beyond what you can get from a single standard.

The Guideline in this report has therefore been prepared as a framework for comparing existing accelerated corrosion tests and should be applicable in the choice of best method and procedure for qualification testing of a product with respect to corrosion resistance.

The Guideline has recently been submitted to the International Organization for Standardization ISO together with a new work item proposal for ISO TC 156 Corrosion of metals and alloys, WG 7 Accelerated corrosion tests.
