ISO 11154:2023/Amd 1:2025

Overview

ISO 11154:2023/Amd 1:2025 is the first amendment to the international standard ISO 11154:2023, focusing on roof load carriers for road vehicles. This amendment, published by the International Organization for Standardization (ISO), provides updated guidelines aimed at enhancing the durability, safety, and performance of roof load carriers used on passenger cars, commercial vehicles, buses, and trailers.

Developed by ISO Technical Committee ISO/TC 22 and Subcommittee SC 40, the amendment reflects advances in test methods and material specifications. It ensures roof load carriers withstand environmental conditions and mechanical stresses according to the latest industry requirements.

Key Topics

• Salt Spray Testing Requirements
  The amendment specifies that degreased roof racks must undergo rigorous salt spray testing in compliance with ISO 9227:2022. This test simulates corrosive environments to verify the corrosion resistance of coatings and materials used in roof load carriers.

• Impact Bending Tests Enhancements
  Updated impact bending tests for material composites now include multiple testing methods per ISO 179-1 variants (1fU, 2n, 3n). These tests apply both to aged and non-aged samples after weathering tests according to ISO 4892-2, guaranteeing material toughness and durability under stress.

• Revised Standard References
  Clause updates reflect current best practices by incorporating the latest corrosion and material testing standards, which guide laboratories and manufacturers in ensuring product compliance.

Applications

ISO 11154:2023/Amd 1:2025 is essential for manufacturers, testing organizations, and regulatory bodies working with roof load carriers on various road vehicles. Its practical applications include:

• Design validation and quality assurance of roof racks to ensure resistance to corrosion, mechanical impact, and environmental aging.
• Ensuring user safety and load security during transportation of cargo via roof racks.
• Supporting regulatory compliance when introducing new roof load carrier models into markets worldwide.
• Facilitating international trade by aligning product performance criteria with globally recognized testing standards.

The amendment aids in maintaining the highest standards in the automotive accessory industry, boosting product reliability and customer confidence.
