Protection of metallic materials against corrosion - Corrosion likelihood in soil - Part 1: General

This standard provides a basis for assessing the corrosion likelihood in soil of buried metallic structures. These structures include for example pipelines, metal sheathed cables, storage tanks, sheet pilings, tower support anchors, culverts and earth reinforcement. Metallic materials covered by the standard are steel, cast iron and stainless steel, as well as copper, lead, aluminium, zinc and their alloys. These metallic materials may be uncoated or coated with other metallic materials.

Korrosionsschutz metallischer Werkstoffe - Korrosionswahrscheinlichkeit in Böden - Teil 1: Allgemeines

Diese Norm dient als Basis für die Beurteilung der Korrosions-wahrscheinlich- keit von erdüberdeckten Anlagen in Böden. Diese Anlage schliessen zum Beispielein: Rohrleitungen, metall-ummantelte Kabel, Vorratstanks, Spundwände, Stützpfeilerveranke-rungen, Kabelkanäle und Erdbewehrungen. Diese Norm deckt die metallischen Werkstoffe ab: Stahl, Gusseisen, Nichtrostender Stahl, sowie Kupfer, Blei, Aluminium, Zink und deren Legierungen.

Protection des matériaux métalliques contre la corrosion - Risque de corrosion dans les sols - Partie 1 : Généralités

La présente Norme européenne sert de base a l'évaluation du risque de corrosion dans les sols de structures métalliques enterrées comme les canalisations, les câbles métalliques sous gaines, les réservoirs de stockage, les parois de palplanches, les supports d'ancrage, les conduits souterrains et les renforcements de sol.
Cette partie de la présente Norme européenne définit les concepts généraux d'une méthode d'évaluation et énumere les principaux facteurs qui interviennent dans la corrosion des structures enterrées.

EN 12501-1:2003 (E)4IntroductionCorrosion analysis of a buried structure is complex due to the interactions of various factors of the corrosionsystem, such as soil, type of metallic material, characteristics of the structure and environment.Consequently, identification and assessment of the factors pertaining to a given corrosion likelihood as defined inthis European Standard are too complex for precise results to be expected solely from the use of this EuropeanStandard. Therefore this European Standard has to be supplemented by expertise and scientific training.The European Standard comprises two parts:Part 1: GeneralPart 2:Low alloyed and non alloyed ferrous materials.1 ScopeThis European Standard provides a basis for assessing the corrosion likelihood in soil of buried metallic structuressuch as pipelines, sheathed metallic cables, storage tanks, sheet pilings, support anchors, culverts and earthreinforcement.This part of this European Standard defines the general concepts for the assessment method and lists the mainfactors influencing the corrosion of buried structures.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanSt
