PPEs are categorized based on the level of risk protection they provide. The European Union, under Regulation (EU) 2016/425, classifies PPE into three categories:
CATEGORY II
CATEGORY III
CATEGORY I
EN 166 Personal Eye Protection: this is the primary standard for all types of personal eye protection. It specifies the general requirements for eye protection, including optical quality, mechanical strength, and protection against various hazards (e.g., dust, liquids, molten metals). EN 175 Equipment for Eye and Face Protection during Welding and Allied Processes: this standard covers the requirements for eye and face protection equipment used in welding. It includes specifications for the design, performance, and testing of welding masks and shields to ensure they provide adequate protection. STANDARD NUMBER
This category covers PPE designed to protect against very serious risks, such as death or irreversible health damage. EG. Code 607A70000
PPE that is not covered under Categories I and III. It provides certified protection against intermediate risks. EG: most of our products
Designed to protect against minimal risks. No need of a certification.
FIELD OF USE (ADDITIONAL MARKINGS WHICH CAN BE FOUND ON FRAME)
Category II and III must be certified by a recognized notified body. Category III PPEs undergo a special control protocol.
