ISO 10062:2022/Amd 1:2024

Overview

ISO 10062:2022/Amd 1:2024 is an important amendment to the third edition of the international standard ISO 10062, which addresses corrosion tests conducted in artificial atmospheres with very low concentrations of polluting gases. This amendment, issued in June 2024 by the International Organization for Standardization (ISO), specifically updates the footnote related to the registered trademark "CAS Registry Number." The amendment clarifies the trademark status and usage of CAS Registry Numbers to ensure users understand the scope and limitations of ISO’s endorsement.

This updated standard plays a crucial role in guiding laboratories and industries that perform precise corrosion testing on metals and alloys under controlled, low pollution conditions, helping maintain accuracy, safety, and consistency in test results worldwide.

Key Topics

• Corrosion Testing in Low-Pollution Artificial Atmospheres
  The standard provides methodologies for evaluating material corrosion resistance when exposed to atmospheres containing very low concentrations of polluting gases, simulating real-world environmental conditions.

• Trademark Clarification on CAS Registry Number
  Amendment 1 revises the footnote on CAS Registry Numbers - trademarks of the American Chemical Society (ACS). It informs users that while CAS numbers are provided for convenience, ISO does not endorse specific products, and equivalent substances may be used if they demonstrate equivalent test results.

• International Collaboration and Standardization
  Developed by ISO Technical Committee ISO/TC 156 in collaboration with CEN/TC 262, this standard reflects global consensus and cooperation across international bodies to promote harmonized corrosion testing procedures.

• Implementation and Intellectual Property Considerations
  The document highlights ISO’s stance on the use of patent rights and trademarks, advising users to verify patent information independently for compliant implementation.

Applications

• Material and Alloy Testing Laboratories
  Laboratories conducting corrosion tests for metals and alloys benefit from this standard to simulate environments with very low pollution levels, ensuring accurate and reproducible results.

• Industrial Quality Control
  Industries such as automotive, aerospace, and construction utilize the standard to evaluate materials’ long-term durability against atmospheric pollutants, aiding in product development and certification.

• Environmental Simulation Research
  Researchers studying corrosion mechanisms under realistic but controlled pollution scenarios apply these test methods to better understand degradation processes and develop protective strategies.

• Standard Compliance and Reporting
  Organizations aiming to meet international corrosion testing benchmarks rely on ISO 10062 amendments to maintain compliance, especially when referencing chemical substances identified by CAS numbers.

Related Standards

• ISO/IEC Directives
  Governs the editorial and procedural rules followed during the development and maintenance of ISO documents, ensuring consistency and quality in international standards.

• ISO 9227 – Salt Spray Tests
  Provides complementary test methods for accelerated corrosion testing in artificial saline atmospheres, often used alongside ISO 10062 for comprehensive corrosion assessment.

• CEN/TC 262 Standards on Metallic Coatings
  Includes standards related to corrosion protection and coatings that complement the testing procedures of ISO 10062 for materials exposed to various environmental conditions.

• ISO 12944 – Paints and Varnishes – Corrosion Protection of Steel Structures
  Addresses corrosion protection measures relevant to the environments simulated under ISO 10062 testing protocols.
