In order to comply with electrical safety in the workplace standards such as NFPA70E an infrared sightglass must be tested for its resistance to electric arc. Without this test programme it is not possible to determine the risk to personnel and select corresponding PPE requirement.
The C-Range Hawk IR Sightglasses have been successfully tested for resistance to electric arcs to both IEC62271-100/200 and ANSI C37 for worldwide compliance.
Arc-Test Series #1 – May 2004, ASTA Testing & Certification Australia (TCA)
Arc-Test Series #2 – March 2006, Rockwell Automation Canada
Arc-Test Series #3 – January 2007, ABB Medium Voltage Arc-Resistant Switchgear, United States
What do these tests mean?
The Hawk IR Sightglass C-Range optic material has been subjected to an energy level equivalent to 40cal/cm2 which falls into an NFPA70E Hazard/Risk Category level 4. This is the highest level of protection available today.
Using this energy level calculation it is possible to install the Hawk IR Sightglasses into existing Arc-Resistant equipment without the need to retest.
