Dear Douglas thanks for this information on the IEC rules. Therefore my summary of all the responses is that it is okay to IR Thermometers to determine Touch temperature hotspots but final measurements should be made using Thermocouples.
Thank you all that have replied.

While I.R> guns and FLIR cameras can be used for diagnostic purposes, I believe they all still want thermocouples for final measurement. In addition, there are rules about the maximum wire gauge and preferences on using special limits of error wire. See IECEE OD-2012 v1.2 for Laboratory procedure for preparation, attachment, extension and use of thermocouples.

Be aware that certification houses usually measure touch (and all other) temperatures with a thermocouple.
