But nothing is ever quite straightforward in the standards world. Some product safety ENs may not mention RTI but have requirements based on other standards (those produced by IEC TC28, for example) that take RTI (Relative Tracking Index) into account. But 'RTI' isn't used, because IEC has already a term 'Relative Temperature Index' that is abbreviated RTI. Or perhaps you meant 'Temperature', and not 'Tracking'! IEC uses the concept of 'Material Groups' to deal with resistance to tracking. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Eat mink and be dreary! ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
