How to ensure that electric wheelchairs meet international safety standards?
Ensuring that electric wheelchairs meet international safety standards is key to ensuring user safety and product quality. Here are some key steps and standards to ensure the safety and compliance of electric wheelchairs:

1. Comply with international standards
Electric wheelchairs need to comply with a series of international standards, including but not limited to:
ISO 7176: This is a series of international standards on wheelchair safety, including requirements and test methods for electric wheelchairs
EN 12184: This is the EU standard for CE certification of electric wheelchairs, which specifies specific requirements and test methods for electric wheelchairs
EN 60601-1-11: This is the electrical safety standard for electric wheelchairs

2. Electrical safety
The electrical system of an electric wheelchair must meet electrical safety requirements to prevent overheating, short circuits, and electrical fires. This includes safety standards for batteries and chargers, such as ISO 7176-31:2023 Wheelchairs Part 31: Lithium-ion battery systems and chargers for electric wheelchairs Requirements and test methods

3. Mechanical safety
Mechanical safety includes ensuring that the various components of the electric wheelchair, such as wheels, brake systems and drive systems, are rigorously tested and verified. This involves static, impact and fatigue strength tests, as well as dynamic stability tests

4. Electromagnetic compatibility
Electric wheelchairs also need to meet electromagnetic compatibility (EMC) requirements to ensure that they do not interfere with other equipment and are not affected by external electromagnetic interference.

5. Environmental adaptability
Electric wheelchairs must be able to work properly in a variety of environmental conditions, including different temperatures, humidity and weather conditions.

6. Performance testing
Performance testing includes testing the maximum speed, climbing ability, braking system and endurance of the electric wheelchair. These tests ensure that the electric wheelchair can meet the daily needs of users

7. Certification and testing
Electric wheelchairs need to be tested and certified by professional third-party testing agencies before entering the market. These organizations will conduct a series of tests based on the above international standards and issue test reports

8. Continuous supervision and maintenance
Even if the electric wheelchair has been certified, the manufacturer needs to conduct continuous supervision and maintenance to ensure the consistency and safety of the product. This includes regular factory inspections and product consistency checks

9. User and after-sales service information
The manufacturer of the electric wheelchair needs to provide detailed user manuals and after-sales service information, including product use, maintenance and repair guides

10. Compliance markings and documents
Finally, ensure that the electric wheelchair has obvious compliance marks, such as the CE mark, and provide all necessary compliance documents and test reports for review when necessary

By following these steps and standards, manufacturers can ensure that their electric wheelchair products meet international safety standards and provide users with safe and reliable products. This is essential to protect the safety of users and enhance the competitiveness of products in the global market.
