Sorry all, it was pointed out the correct document is  IECEE OD-5012 v1.2

All the best, Doug

Test labs are required to follow IEC rules about temperature measurements.
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.  Formerly OP-108.

Thanks Ted for your comprehensive reply. As I said in my earlier replies if the 
IR measured touch temperatures are near the test limits then thermocouples 
should be used to provide a more accurate measurement.

temperature Testing in accordance with EN 62368-1

Hi Philip,

I would like to see progress towards the acceptance of infrared thermography 
for certification. However, I can see some potential issues.

  *   I haven’t seen software for many IR cameras that does good data logging. 
I work on some products that have cyclical temperature changes. There are 
situations where I need to see a graph of touch temperature over time before I 
can make an assessment, particularly when I’m just trying to determine if 
temperatures have stabilized.
  *   I don’t know how well IR thermography will work when there are different 
materials. I have a product that has metal, plastic, fabric and glass in close 
proximity. I believe that the variety of materials might increase the 
uncertainty of measurement for an IR camera. This isn’t an issue if taken into 
account, but it might be a challenge where touch temperatures are close to the 
limit.
  *   It’s becoming more common to find IR camera calibration services, but 
“more common” doesn’t mean cheap or easy.

I think the technology has reached a point where IR cameras could be used for 
testing, but I would want to see internationally accepted procedures before I 
would consider it. I’m sure that there are experts in the field who could help. 
I use IR cameras to find hot spots for my testing, and they have been 
invaluable, particularly where the hottest points change depending on the mode 
of operation.

Hello Regulatory Experts,
We do use an IR camera as an initial indicator, to identify the hottest areas 
for further investigation of the hottest areas using thermocouples.
Our products typically have cast metal enclosures, so we coat enclosure areas 
with a flat painted finish to obtain reasonably accurate indication. (we find 
that semi-reflective, or black surfaces can “muddy the waters” )
I hope this helps.

Thank Rich for your reply. That is my view as well. I use thermocouples for 
temperature rise measurements.

Hi Phillip:

As far as I know, 62368-1 does not specify the method for measuring touch 
temperatures.  Be aware that certification houses usually measure touch (and 
all other) temperatures with a thermocouple.

Stay safe, and best regards,
Rich

Dear List Members

I am looking for advice of whether the use of an Infra Red (IR) Digital 
Thermometer is suitable for performing Touch temperature Testing in accordance 
with EN 62368-1. Provided that factors for the different surface materials are 
applied to the temperature measurements?

If you prefer to reply to me directly instead of vis the listing please do so 
at pw...@hotmail.co.uk.

Thanks in advance for your help.

Regards

Philip Stevenson
