Infrared Windows For Inspection Safety and Certainty Call Atlas Inspection Today for IRISS Brand VPFR50 IR viewing panes - Available in 2", 3", & 4" View Diameters and backed by a 25 Year Manufacturer's Warranty Complies with impact and load requirements of IEEE C.37.20.2 section a.3.6 Meets impact and flammability requirements of UL Standard 508C and 746C UL94 5VA Flammability Rated Assembly IP 65/NEMA 4 Rated both open and closed Allows for safe thermal imaging of fully energized electrical components through closed doors Works with all infrared cameras Manufactured with non conductive materials Available in 8 infrared transmissive materials Simple to install in 10 minutes or less This series meets the mandatory IEEE Standard (C.37.20.2 section a.3.6) for visual viewing panes in medium and high voltage electrical equipment (36 kV metal clad and 72kV station switchgear) and allows IR inspections to be completed safely as per the requirements of NFPA 70e. No other infrared viewing pane assembly available today meets these requirements for severe pressure, impact and flammability. Thermal Inspections of Electrical Equipment IRWindows Studio National Fire Protection Association's (NFPA) specification NFPA 70E establishes guidelines for safe work practices around live electrical components. This is changing how thermographers can conduct thermal inspections of low, medium and high voltage electrical equipment. Infrared Windows help Predictive Maintenance (PdM) thermographers comply with NFPA 70E by allowing them to scan the electrical equipment without opening or removing covers of electrical enclosures. Scanning without opening enclosures greatly reduces the risk of Arc Flash, it makes inspection faster, and takes away many of the triggers of an arc flash. The first Element of any risk assessment is the adoption of the hierarchy of control whose first principal is to ELIMINATE RISK. The use of personal protective equipment (PPE) should always be considered as a last resort. IRISS Infrared windows are used to remove the risk to thermographers by ensuring that they are never exposed to energized electrical equipment while inspecting equipment, therefore ensuring safe IR inspections of electrical switchgear. Additionally the use of this type of inspection methodology means that the switchgear always remains shut during the inspection eliminating 99.9% of the causes of arc flash.
