Greetings to all, In EN61010-1 section 10 and EN60950 safety standards, there are surface temperature limits specification for Normal Condition based on an Ambient Temperature of 40ºC. Our company makes analytical instrumentation and a new product we are working on is functionally very susceptible to room temperatures. So, the operational specification in our manual says it must be in a room no warmer than 30ºC.
Question is, is it proper to consider surface temperatures for safety based on a 30ºC ambient which would give us 10º more range to work with? Someone told me you could do this but it doesn't seem right to me. You are relying on the building's air conditioning as a level of protection. Then I was told that if the AC broke down it would be considered a Fault and then the 105ºC limit would be applied. Is this correct thinking? Knowing the correct way to apply these requirements effect the design of our instruments so it is important for me to know. Thanks to all in advance. Brian Kunde LECO Corp.
