TS 5731 EN ISO 8044

TS 5731 EN ISO 8044 is a terminology standard that brings together the basic terms and definitions used for corrosion of metals and alloys. Corrosion is the undesired change of a metal or alloy caused by interaction with its environment, so a common vocabulary helps reduce ambiguity in research, design, inspection, and maintenance work.

The standard states that it covers corrosion terms widely used in modern science and technology. In general technical terms, this means it supports consistent naming of the main forms and concepts of corrosion: for example, uniform attack, localized corrosion, protective films, passivation, galvanic interaction, and stress-corrosion concepts are all handled within one shared terminological framework. Its purpose is not to prescribe a new test method or numerical acceptance limit, but to align how the terms themselves are understood and used.

Why corrosion terminology matters

In corrosion engineering, small differences in wording can lead to major differences in material selection and damage analysis. For instance, “corrosion rate,” “corrosion resistance,” and “corrosion product” do not mean the same thing; each describes a different aspect of the process. A foundational vocabulary like this helps keep the same terms aligned across materials science, metallurgy, energy facilities, transport systems, and structural maintenance practice.

This record also belongs to a withdrawn standard, so it should be understood as a historical terminology reference describing the subject area rather than an active current edition. Even so, its scope remains useful for understanding core corrosion concepts, reading technical literature correctly, and maintaining consistent professional communication.
