What is UL 60335-2-406?

Introduction

UL 60335-2-406 is a specific safety standard within the UL 60335 series of standards. It focuses on safety requirements for equipment utilizing lasers or intense light sources (excluding those used for medical purposes). This standard is essential to ensure the safe operation of various consumer and professional devices, such as laser printers, projectors, and stage lighting systems.

Key Requirements of UL 60335-2-406

The primary objective of UL 60335-2-406 is to prevent potential hazards arising from the use of lasers and intense light sources in electronic equipment. Some of the key requirements include:

Emission Limits: The standard sets specific limits on the maximum permissible emission levels for different types of lasers and intense light sources. These limits help minimize the risk of eye injuries to users and bystanders.

Protective Measures: Equipment must incorporate appropriate safety features, such as interlocks and warning labels, to alert users about potential risks and protect them from accidental exposure to harmful radiation.

Electrical Safety: UL 60335-2-406 also addresses electrical safety aspects, including insulation requirements and protection against electric shock. This ensures that equipment operates safely both in terms of light emissions and electrical components.

Testing and Certification

In order to comply with UL 60335-2-406, manufacturers must subject their products to thorough testing conducted by accredited laboratories. Testing includes examining the performance of safety features, assessing compliance with emission limits, and verifying adherence to electrical safety standards.

Once a product successfully meets all the necessary criteria, it can be certified as compliant with UL 60335-2-406. The certification mark provides reassurance to consumers and end-users that the equipment has undergone rigorous testing and meets the required safety standards.

Conclusion

UL 60335-2-406 plays a crucial role in ensuring the safety of devices that utilize lasers or intense light sources. By setting emission limits and requiring appropriate safety features, this standard reduces the risk of harm to both users and bystanders. Manufacturers must comply with UL 60335-2-406 and subject their products to testing and certification procedures to ensure their equipment meets the required safety standards.
