Estimating Temperature by Touch

I can touch a smooth metal surface at 50C forever, 60C for about 2 seconds, and can interpolate pretty well berween.

Calibrate yourself!

I added some above. For most folks, 70 is about as hot as one can stand for a second or two (does depend on calluses, though).

Don't know about that but I used to know someone who used his tongue as a voltmeter for determining the voltage of batteries.

Mmm...

I have measured the "surface" temp of a 60W typical bulb and came out appox 80C with temp probe attachment for multimeter.

I used to do temperature testing of RF equipment in a walkin temperature chamber and changed cables at 80 deg C. Screwing and unscrewing N connectors bare-handed was a real challenge. 80 C is definitely in the hot range.

I also once had to install some electronics on an all steel crane while it was operating over a furnace. The temperature on the crane was 155 F or about 68 C.

Confirmed.

50C is now the legislated limit for hot water systems as it will not scold. 60C maybe 5 secs max. depending on your level of tolerance to pain. It is the legislated as the cut off point as well.

Hi!

I can second that. My IR thermometer (at a few inches) said my 130V 60W bulbs were between 86 and 90 degrees C.

Yea. 113F and you will let go. Blisters at 150F.. However, my wife is a cook and most of her finger tips have been burnt over the years. She can hold 150 for several seconds. I know. She passes hot dishes to me and I drop them.

I have skin on my fingertips that's like a baby's skin...those well-known Samsung vertical IC heatsinks are hotter than I can handle.
