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.

Overview

EN 12501-1:2003 - Protection of metallic materials against corrosion - Corrosion likelihood in soil - Part 1: General (CEN) provides a structured basis for assessing the likelihood of soil corrosion affecting buried metallic structures. It applies to a wide range of buried assets (pipelines, metal-sheathed cables, storage tanks, sheet piling, anchors, culverts, earth reinforcement) and to common metals and alloys including steel, cast iron, stainless steel, copper, lead, aluminium, zinc and their alloys (coated or uncoated). EN 12501-1 defines general concepts, assessment steps and the main factors that influence corrosion in soil, and it is intended to be used together with Part 2 and other product- or protection-specific standards.

Key Topics

  • Corrosion load in soil: Defines the concept and introduces a practical assessment framework that combines soil parameters, structure characteristics and environmental factors.
  • Three-class classification: Corrosion load in soil is classified as LOW / MEDIUM / HIGH for a given metal; this reflects the probability of corrosion rates or specific corrosion types (e.g., pitting, crevice corrosion).
  • Assessment procedure: A stepwise method (Annex A) covering:
    • Preliminary enquiry (design documents, geological/hydrological maps)
    • Site survey (physico-chemical soil characteristics, pollution indicators, voltage gradients)
    • Soil sampling and laboratory analysis
  • Factors influencing soil corrosion (summarized in Annex B): soil texture and resistivity, pH, water content, salts (chlorides, sulfates), bacterial activity (sulfate-reducing bacteria), backfill, structure geometry, coatings, electrical continuity and stray/current influences.
  • Limitations and scope: Part 1 gives general guidance; detailed quantitative assessment and metallic-specific criteria are in EN 12501-2 (low-alloy and non-alloy ferrous materials). Cathodic protection design and measurement are outside the detailed scope (see related standards).

Applications and Users

  • Practical for engineers and corrosion specialists performing soil corrosion assessments for new design, maintenance planning or risk analysis of buried metallic infrastructure.
  • Used by pipeline operators, utility companies, civil/structural engineers, asset managers and consultants to:
    • Identify risk of appearance of corrosion damage
    • Decide monitoring needs and the necessity for additional protective measures (coatings, cathodic protection)
    • Inform design choices and service-life expectations
  • Useful input for environmental site investigations, soil sampling campaigns and pre-construction reviews.

Related Standards

  • EN 12501-2 - Corrosion likelihood in soil: Low-alloyed and non-alloyed ferrous materials
  • EN 12954, EN 13509 - Cathodic protection and measurement techniques
  • prEN 50162 - Protection against corrosion from stray DC currents

Keywords: EN 12501-1, corrosion likelihood in soil, buried metallic structures, soil corrosion assessment, corrosion load, soil sampling, cathodic protection.
