EN 166:2002
EN 166:2002 is a European technical performance standard for eye protection. All manufacturers of safety eyewear are required to have their products independently tested against this European standard. Both the frame and lens are tested, therefore both must include the CE symbol and the manufacturer’s logo. The CE marking certifies that a product has met EU consumer safety, health or environmental requirements.
Within the standard, there are numerous levels of compliance, depending on the end use of the piece of equipment in question.
