Hi everyone,
I have a question regarding a fire prevention clause in the 3rd edition of the IEC 60601-1.
Oxygen rich environment is defined as an environment in which the concentration of oxygen is greater than 25% for ambient pressures up to 110kPa or the partial pressure of oxygen is greater than 27.5kPa at ambient pressures exceeding 110kPa.
If i have an outlet discharging 35% oxygen into an enclosure (approx 270x300x450mm) with 2 exhaust fans and the measured oxygen level 10mm away from the outlet is only 22% oxygen; so oxygen greater than 25% is only in that 10mm radius around the outlet, is that enclosure still considered an oxygen rich environment?
Appreciate any input!
PS. If the fans were not working, the radius increases to 25mm.
