Regulation EN 361: "Personal protective equipment against falls from a height - safety harnesses" sets down which technical properties a safety harness has to have when used as a PPE component.
EN 361 provides a detailed description of the general requirements and labelling specifications pertaining to safety harnesses as well as which information needs to be supplied on the manufacturer and how safety harnesses need to be packed. Testing is carried out in line with EN 364.
