Full title and description

ISO 10271:2020 — Dentistry — Corrosion test methods for metallic materials. This International Standard specifies test methods and procedures to determine the corrosion behaviour of metallic materials intended for use in the oral cavity; it is intended to be referenced by individual standards that specify specific dental metallic materials.

Abstract

Provides standardized laboratory test procedures (immersion and electrochemical techniques, specimen preparation and examination) to evaluate corrosion resistance and behaviour of dental alloys and other metallic materials used in restorative and prosthetic dentistry. The standard is not applicable to dental instruments.

General information

• Status: Published (current edition).
• Publication date: September 2020.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 11.060.10 (Dental materials).
• Edition / version: Edition 3 (2020).
• Number of pages: 32 (ISO edition).

Scope

Specifies test methods and procedural details to assess corrosion behaviour of metallic materials used in the oral cavity (including methods intended to be referenced by material-specific standards). Excludes dental instruments. The procedures are intended for use when specifying or verifying metallic dental materials.

Key topics and requirements

• Standardized specimen preparation and preconditioning for corrosion testing (surface finishing, dimensions, cleaning).
• Immersion (static or dynamic) test methods in simulated oral media and solutions.
• Electrochemical test methods (potentiodynamic/potentiostatic measurements, corrosion potential, current density evaluations and related techniques).
• Gravimetric (mass-loss) and visual/microscopic examination methods to quantify corrosion attack and surface changes.
• Criteria and reporting requirements for results, including test conditions, media composition and temperature.
• Guidance for interpretation of corrosion behaviour for dental alloys and metallic prosthetic components.

Typical use and users

Used by dental materials manufacturers, testing and accreditation laboratories, regulatory bodies, standards committees, dental researchers and quality departments to evaluate and document corrosion resistance of dental alloys and metallic components for restorative and prosthetic use. Test methods are referenced when specifying materials for crowns, bridges, implants-related components and other intra-oral metallic devices.

Related standards

Commonly referenced alongside other dentistry and materials standards such as ISO 22674 (metallic materials for fixed and removable restorations), ISO 1942 (dentistry vocabulary) and relevant biocompatibility and compatibility standards (for example ISO 10993 series and ISO compatibility tests). National/adopted versions (for example BS EN ISO 10271:2020) also exist.

FAQ

Q: What is this standard?

A: An ISO International Standard (ISO 10271:2020) that specifies laboratory test methods and procedures to determine the corrosion behaviour of metallic materials used in the oral cavity.

Q: What does it cover?

A: It covers specimen preparation, immersion and electrochemical corrosion test methods, examination and reporting procedures for dental metallic materials; it does not apply to instruments.

Q: Who typically uses it?

A: Dental materials manufacturers, independent testing laboratories, regulators, standards developers, and researchers involved in materials evaluation and biocompatibility/compatibility assessment for dental applications.

Q: Is it current or superseded?

A: Current edition published in September 2020 (Edition 3). It superseded earlier editions (2011 and 2001). Users should confirm national adoptions or revisions with their national standards body for any subsequent confirmations or amendments.

Q: Is it part of a series?

A: It is part of the body of ISO dentistry standards dealing with dental materials and testing methods and is commonly referenced alongside material-specific standards (for example ISO 22674 for metallic restorative materials) and related ISO documents on vocabulary, biocompatibility and compatibility testing.
