Full title and description

ISO 17752:2012 — Corrosion of metals and alloys — Procedures to determine and estimate runoff rates of metals from materials as a result of atmospheric corrosion. This International Standard specifies procedures for measuring and estimating the rates at which metal species are washed off materials (metals, alloys and coatings) exposed to outdoor atmospheric conditions, and provides guidance for reporting and interpreting runoff data.

Abstract

This standard defines methods to determine and estimate metal runoff rates caused by atmospheric corrosion under open‑air exposure. It covers sampling/exposure arrangements, collection and analysis of runoff, calculation of runoff rates and reporting conventions so that results are comparable and can be used for environmental assessment, materials selection and lifetime estimation.

Scope

ISO 17752:2012 applies to metals, metal alloys and metallic coatings (including coated systems) exposed to the atmosphere in the open air. It provides standardised procedures for the exposure of specimens, collection of runoff (precipitation/leachate) generated by atmospheric action, chemical analysis of collected runoff for metallic constituents, and calculation/estimation of runoff rates expressed in appropriate mass per area per time units. The standard is intended to produce comparable runoff-rate data for environmental assessment, materials evaluation and corrosion management.

Key topics and requirements

• Definition of specimen preparation and open‑air exposure arrangements for runoff collection.
• Instructions for collection, handling and chemical analysis of runoff (sample integrity and reporting).
• Calculation methods for expressing runoff rates (mass per area per time) and estimation procedures for environmental exposure scenarios.
• Applicability to metals, alloys and protective coatings; guidance on interpreting runoff in relation to atmospheric corrosivity factors.
• Reporting format to support comparison between sites and materials (metadata on exposure conditions, time of wetness and pollutant context).

Typical use and users

Practitioners in corrosion science and testing laboratories, materials and coatings manufacturers, environmental and regulatory agencies, infrastructure and asset managers, and research organisations use this standard to quantify metal release from exposed materials, inform material selection decisions, support environmental impact assessments, and integrate runoff data with atmospheric corrosivity classifications and lifetime prediction models.

Related standards

ISO 17752 is part of the ISO corpus on atmospheric corrosion and is typically used alongside standards that describe atmospheric corrosivity and specimen corrosion rates, for example ISO 9223 (Corrosivity of atmospheres — classification, determination and estimation), ISO 9226 (Determination of corrosion rate of standard specimens for evaluation of corrosivity) and ISO 9227 (Salt spray tests — artificial atmosphere corrosion tests) depending on the assessment and test goals.

FAQ

Q: What is this standard?

A: ISO 17752:2012 is an ISO International Standard that specifies procedures to determine and estimate runoff rates of metals from materials exposed to atmospheric corrosion in the open air. It provides methods for specimen exposure, runoff collection, analysis and calculation of runoff rates.

Q: What does it cover?

A: It covers practical procedures for preparing specimens, arranging open‑air exposures, collecting and analysing runoff (precipitation/leachate) produced by atmospheric corrosion, and for calculating and reporting runoff rates so results are comparable across sites and materials.

Q: Who typically uses it?

A: Corrosion test laboratories, materials and coatings manufacturers, environmental assessors, infrastructure owners and researchers use the standard to quantify metal release from exposed materials and to support material selection, compliance and environmental impact assessments.

Q: Is it current or superseded?

A: ISO 17752 was published in July 2012 (first edition) and is listed as a published International Standard; it is not shown as withdrawn or superseded in the ISO catalogue entry. Users should check the ISO catalogue or their national standards body for any revisions or confirmations after 2012 before relying on it for regulatory purposes.

Q: Is it part of a series?

A: It is part of the ISO portfolio dealing with atmospheric corrosion (work of ISO/TC 156) and is commonly used together with related ISO standards such as ISO 9223, ISO 9226 and ISO 9227 for a comprehensive assessment of atmospheric corrosivity, corrosion rates and laboratory corrosion testing.
