Posted By Nick Higginson Can anyone help? I know that EN166 relates to eye protection, but can anyone tell me what EN166 1b39 relates to? To what standard will the eye protection protect against? Regards, Nick

Posted By Diane Warne Nick, I think the 1b39 may be the frame/lens marks(under EN166) for the particular type of eye protection you are looking at. If 1 is a lens mark that is probably refractive tolerance which is measured 1 to 3, 1 being the best (least distorting.) B is impact resistance "Medium" or Grade 1, i.e. up to 120m/s velocity, equal to the old BS2092:1. 3 and 9 are about what it protects against, 3 being liquids (chemical) and 9 being molten metals and hot solids. I got all this from a table I copied from somewhere about BSEN marnings - I think it's right, but it might be best to check with the manufacturer. Best wishes Diane
