Overview
ISO 16840-10:2021/Amd 1:2024 is an amendment to the international standard ISO 16840-10, which specifies requirements and test methods for assessing the resistance to ignition of postural support devices (PSDs) used in wheelchair seating. This amendment introduces additional annexes and a detailed alternative test method, helping further enhance the safety, reliability, and compliance of wheelchair seating components worldwide.
With the risk of fire and ignition posing critical safety concerns for wheelchair users, this updated standard provides manufacturers, testers, and regulatory bodies with thorough guidance to evaluate components under controlled laboratory conditions. The standard helps ensure safer mobility and protection for end-users and supports manufacturers in meeting global compliance requirements.
Key Topics
- Resistance to Ignition: Core criteria and processes for evaluating whether materials used in wheelchair postural support devices ignite or smoulder when exposed to a heat source replicating a smouldering cigarette.
- Test Methods: Introduction of an alternative heat source-a NiCr (nickel-chromium) wire coil-to simulate ignition sources, with comprehensive procedural guidance.
- Sample Preparation: Guidance on test sample orientation (horizontal or vertical), surface selection based on intended use, and pre-test conditioning to simulate real-world conditions.
- Test Environment: Requirements for controlled temperature, humidity, airflow, and the necessary safety measures for technicians during testing.
- Test Equipment Construction: Detailed steps to fabricate and calibrate the NiCr wire coil apparatus, with a parts list for ease of implementation.
- Reporting Requirements: Inclusion of a structured test report template to ensure consistent documentation of results and processes.
- Annexes: Addition of informative annexes (D, E, and F) providing supporting guidance on the NiCr coil method, apparatus construction, and sample test report.
Applications
This amendment to ISO 16840-10 is highly practical for a range of professionals and organizations, including:
- Wheelchair Manufacturers: Ensures all PSDs integrated into wheelchair seating systems meet rigorous ignition resistance criteria, boosting product safety and market acceptance.
- Testing Laboratories: Offers clear, validated procedures and calibration instructions for laboratory personnel, improving result reliability and testing repeatability.
- Regulatory Authorities: Provides a harmonized approach for auditing, verification, and certification of wheelchair and PSD components in line with international fire safety standards.
- Assistive Technology Developers: Guides the research and development of new seating materials or postural support components to meet contemporary fire safety benchmarks.
- Procurement and Healthcare Providers: Ensures decision-makers can specify, source, and implement products that have been tested according to the latest fire safety protocols.
