Full title and description

ISO/TR 16203:2023 — Overview of methods available for particle-free erosion corrosion testing in flowing liquids. This technical report summarises available laboratory and bench-scale test methods, test conditions and typical measurement approaches used to evaluate erosion–corrosion of materials exposed to single-phase flowing liquids without suspended particles.

Abstract

This document provides an overview of the erosion corrosion tests of materials in single-phase flowing liquids and the test methods available, offering guidance to help users select appropriate test methods for particle-free erosion–corrosion evaluations.

Scope

Provides an overview of erosion–corrosion tests for materials exposed to single-phase flowing liquids (i.e., particle-free conditions). The report describes the types of test methods in use, typical test rigs and specimen arrangements, the principal variables to control (flow velocity, temperature, chemistry, exposure time), and common measurement/assessment endpoints used to characterise erosion–corrosion behaviour. It is an informational guidance document (Technical Report) intended to assist selection of appropriate test methods rather than to prescribe a single normative test procedure.

Key topics and requirements

• Overview of laboratory and bench-scale methods for particle‑free erosion–corrosion testing (test rigs, rotating samples, flow loops, coupon arrangements).
• Principal test variables: liquid velocity/profile, temperature, pH/chemistry, flow regime, exposure duration and specimen orientation.
• Common measurement and assessment endpoints: mass loss, pit morphology, metallographic examination, electrochemical monitoring and post‑test surface analysis.
• Guidance on selecting a test method appropriate to the service environment and material under evaluation (matching test severity and measurement sensitivity to the expected field damage mode).
• Notes on limitations of particle‑free test methods and the need to consider particulate/multiphasic conditions separately (i.e., this TR focuses on single‑phase, particle‑free flows).

Typical use and users

Used by corrosion engineers, materials scientists, test house and quality laboratories, R&D groups, manufacturers of piping, heat exchangers and fluid‑handling equipment, and standards committees seeking a concise survey of available particle‑free erosion–corrosion test approaches. It assists practitioners who must choose or justify test methods for qualification, comparative evaluation or research into flow‑induced corrosion mechanisms.

Related standards

Key related documents and series include the earlier ISO/TR 16203:2016 (withdrawn and superseded by the 2023 edition), vocabulary and general corrosion references from ISO/TC 156 (for example ISO 8044 and ISO 8407), and other corrosion testing standards such as ISO 9227 (salt spray) and the ISO 12944 series (protective paint systems). These documents are complementary: ISO/TR 16203:2023 focuses specifically on particle‑free flowing‑liquid erosion–corrosion test methods and selection guidance.

FAQ

Q: What is this standard?

A: ISO/TR 16203:2023 is an ISO technical report that provides an overview and guidance on available methods for testing erosion–corrosion of materials in single‑phase (particle‑free) flowing liquids. It is informational rather than a prescriptive test method standard.

Q: What does it cover?

A: It summarises types of test rigs and specimen arrangements, the key variables to control (flow velocity, temperature, chemistry, exposure time), common measurement endpoints (mass loss, surface analysis, electrochemical measurements) and guidance for selecting an appropriate test method for particle‑free flowing liquid conditions.

Q: Who typically uses it?

A: Corrosion/materials engineers, laboratory managers, R&D teams, test houses and manufacturers of equipment exposed to flowing corrosive liquids who need help selecting or justifying particle‑free erosion–corrosion test approaches. Standards committees and academics may also use it as a concise survey of methods.

Q: Is it current or superseded?

A: Current — ISO/TR 16203:2023 (Edition 2) was published in August 2023. It supersedes and replaces ISO/TR 16203:2016 (the 2016 edition was withdrawn). Users should reference the 2023 edition for the latest guidance.

Q: Is it part of a series?

A: It is part of the body of ISO work on corrosion of metals developed by ISO/TC 156 and sits among other corrosion guidance and test standards (vocabulary and test procedures) produced by that committee; it complements normative test standards (e.g., ISO 8407, ISO 9227) and vocabulary standards.

Q: What are the key keywords?

A: Erosion corrosion; particle‑free; flowing liquids; test methods; mass loss; electrochemical monitoring; flow loop; ISO/TC 156.
