BS EN ISO 12944-2:2017,Paints And Varnishes—Corrosion Protection Of Steel Structures By Protective Paint Systems — Part2:Classification Of Environments.
This document supersedes EN IS0 12944-2: 1998
BS EN ISO 12944-2:2017 deals with the classification of the principal environments to which steel structures are exposed, and the corrosivity of these environments.
ISO 12944-1 defines the overall scope of ISO 12944. It gives some basic terms and definitions and ageneral introduction to the other parts of ISO 12944. Furthermore, it includes a general statement on health, safety and environmental protection, and guidelines for using IS0 12944 (all parts) for a given project.
BS EN ISO 12944-2 describes the environmental impact on steel structures. It covers structures exposed to the atmosphere as well as those immersed in water or buried in soil. For different atmospheric environments, a classification system based on corrosivity categories is also presented. Different environments for immersed and buried structures are also described. All these environments are relevant to the choice of protective paint systems.
