What is EN ISO 11681-3:2016?

EN ISO 11681-3:2016 is a technical standard that focuses on the safety requirements and test methods for eyewear specifically designed to protect against intense light sources. It provides guidelines and specifications for sunglasses and related products, ensuring their effectiveness in protecting the eyes against harmful radiation.

The Importance of EN ISO 11681-3:2016

This standard plays a crucial role in safeguarding the eyes of individuals who work in environments with strong light sources, such as welders, laser technicians, or those exposed to intense sunlight. Compliance with EN ISO 11681-3:2016 ensures that eyewear provides the necessary protection from optical radiation, preventing potential eye injuries and long-term damage caused by prolonged exposure.

Key Requirements of EN ISO 11681-3:2016

EN ISO 11681-3:2016 outlines various essential requirements for eyewear. These include the ability to block specific wavelengths of light, ensuring the filter category is appropriate for the intended use, and maintaining the integrity and durability of the eyewear. The standard also requires manufacturers to provide clear instructions on the correct use and maintenance of the eyewear, as well as guidelines for testing and labeling.

Testing and Certification Process

To ensure compliance with EN ISO 11681-3:2016, eyewear must undergo rigorous testing by authorized laboratories. These tests evaluate factors such as visible light transmission, impact resistance, hinge strength, compatibility with other protective equipment, and resistance to heat and flame. Only after successfully meeting all the requirements of the standard can eyewear be certified and labeled accordingly.

By adhering to the testing and certification process outlined by EN ISO 11681-3:2016, manufacturers and consumers can have confidence in the quality and safety of eyewear products. Compliance ensures that the eyewear provides reliable protection against intense light sources and contributes to the overall well-being and vision health of individuals working in hazardous environments.
