What is EN 166027:2004-2015?

EN 166027:2004-2015 is a technical standard that specifies the requirements and testing methods for safety eyewear. It is designed to ensure that protective eyewear provides adequate protection against various hazards in the workplace and other areas where eye protection is necessary. This article aims to explain the key aspects of this standard in an easy-to-understand manner.

General Requirements

The standard outlines the general requirements for safety eyewear, including design, materials, and ergonomic considerations. It specifies that the eyewear should provide a proper fit, coverage, and optical performance. The lenses should be impact-resistant and protect against harmful radiation such as UV rays. The frames should be durable and comfortable to wear for extended periods.

Testing Methods

EN 166027:2004-2015 also defines the testing methods that should be used to evaluate the performance of safety eyewear. These tests include assessing the optical qualities of the lenses, such as clarity and distortion. Impact resistance tests are performed to measure the eyewear's ability to withstand high-velocity impacts from various angles. Other tests determine the resistance to heat, chemicals, and fogging.

Marking and Certification

The standard requires safety eyewear to be appropriately marked with relevant information, including the manufacturer's name or trademark, the lens properties, and the compliance with the standard (EN 166027:2004-2015). This marking ensures that users can easily identify suitable eyewear and have confidence in its protective capabilities. Additionally, certification bodies oversee the compliance with the standard through regular inspections and audits.
