All,
I am having some fun with a lab over RTI ratings on plastics. Basically we have a plastic moulding with a component mounted directly on it. The RTI of the plastic is 60C and the component is getting to around 75C actual. I have always looked at the flammability of plastics 5V, V-0, V-1, etc but never the RTI. Is this a just a UL1950 requirement or is it in EN60950 as well. We have done the thermal stress at 70C and all is OK. They are suggesting doing the ball pressure test at 125C, however, I have only used this for qualifying mains transformer bobbins, etc. Regards Tony Reynolds Pitney Bowes +44 (0) 1279 449479 +44 (0) 1279 449118 [email protected] ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
