CERTIFICATION
All the Univet laser safety windows are certified according European standard EN207 “Personal eye-protection equipment. Filters and eye-protectors against laser radiation (laser eye-protectors)”. This norm requires the measurement of the optical density (OD) and the fullfillment of the stability to laser radiation test. At the conclusion of the certification process an independent Notified body issues an official EU-type certificate. Selected products are tested with a laser damage test based on a time base of 10 seconds, instead of the 5 seconds requested by EN207. In addition, European standard EN12254 “Screens for laser working places. Safety requirements and testing” is in some cases used. This norm uses a different time base (100 seconds) and a higher power/ energy density for stability to laser radiation test compared to EN207.
MARKING
Marking according European standards EN207 and/or EN12254 is applied on every laser safety window. Depending on the dimensions of the window and the length of the marking, different styles are used.
SHAPE AND DIMENSIONS
Univet only and exclusively supplies windows ready for installation, which shall not be cut or shaped by the user.
RESPONSIBILITY Laser safety windows are certified according to European standards: the user is not authorized in any case to cut, shape or modify what is supplied. This action will lead to the instant decay of the certification, to a complete assumption of responsibility by the user and to a pos- sible action by Univet for tampering with a certified product.
CUSTOMIZED SHAPE Univet is pleased to supply windows cut according to customized shapes, including radius or holes. Maximum dimensions are defined in the following table. A 2D file shall be provided for evaluation of feasibility and for production: autocad ‘dwg’ or ‘dxf’ files are requi- red, ‘pdf’ or ‘jpg’ file are not acceptable. Univet may ask additional information or values if the information reported in the 2D file are not complete or correct.
