RE: ITE standard - hot air
Vijay, I am not aware of standards specifying this, but in practical terms, heat transfer would depend on airspeed, time, surface area, etc. For example, high speed air would burn much faster than convected air. If this is a significant safety concern rather than a standards compliance question, you might try ASTM standard C 1057 which uses a thermesthesiometer, a probe simulating skin. It would be able to demonstrate the risk or safety of exposures to your conditions, a much better risk analysis than just standards compliance.

RE: ITE standard
On November 5 Sylvia Toma writes; GR-65 (Network Equipment Building System Requirements: Physical Protection) has a section (4.1.4) on Heat Dissipation.Table 4-6 outlines the equipment area heat release for individual frame, multi-frame and shelf equipment for both natural convection and forced-air fans. Typo here, I suspect. Could you be referring to Telcordia standard GR-63?

ITE standard used in Poland.
Hi Sandy: You ask: Does anyone know the ITE test standard requirements for Poland? Poland uses IEC 950. (And accepts CB Reports.) Polish certification of ITE is required. I believe the only country in the world that does not use an IEC 950 clone is Mexico. Mexico uses a UL 478 clone. Since IEC 950 largely includes UL 478 requirements, compliance with IEC 950 largely implies compliance with UL 478.
