Testing the NFC Ring at different temperatures
-
I'm pretty sure they should survive a dishwasher and laundry machine but I don't think it will survive a microwave, worth testing though!
-
Ah ha sounds good. Keep us posted with the results John. Besides laundry, since we are on the temperature topic, drying machine would also be a good candidate, as it also tumbles.
-
@victor
I agree about the dryer. -
Well the problem with the laundry and the drying machine will probably only be the scratches it makes on the ring.
@asbath The cold shouldn't be a problem but wearing rings in the cold is dangerous because the metal transport the body temperature easily. (you probably know better than me, but this is more a general warning for those who don't :-)
-
@Lafunamor Indeed, I assume that the cold is less of a problem for the inlays than severe heat would be. But it's always best to test both ends of the spectrum to make sure you've covered all the bases. That's proper QA after all!
-
@asbath sure. I didn't mean it shouldn't be tested.

Just saw John's reply on the KS website:
"2) We tested the rings at 200 degrees C and they still worked after 10 minutes so we just sent a test set to our deep freeze facility (my local butchers) and we should know the test results of that tomorrow"
Ah so your butcher said yes! Very interested to know how the ring fares :)

We tested the rings at -32° C for 24 hours and 4 of the 5 rings survived. One seems to have died on one side.
The one that died is the one that we baked at 200° C prior to sending it down to the butchers, it did get time to settle back down to room temperature but it could be that the expansion/contraction over a longer period of time was the cause.
I think further testing is required. If we experience a 20% failure rate at -32° C that needs to be documented. I think we need to discover how long a ring can be exposed to extreme colds before showing signs of failure, it's clear that this again is going to one of those tests where the human is more likely to perish prior to the ring but still, knowing your limits is always a good thing.
I'm happy with the tests so far and will continue to post our findings. I will try to pick this test back up in June or so.

Washed my Alpha ring in my pants pocket by accident the other day... Still working fine after a 90 degree Celsius wash followed by a tumble dry.
I think the ring hates me, but it's still doing its job. -

Indeed, nobody would be out in -32C for long. And even then, if you were out there for more than a few hours at a time you're going to be wearing a lot of gear to reduce any exposed skin as much as possible. That should raise the temperature.
But I really appreciate that you've taken the time to test the ring in extreme temperatures. As an avid skier (and neighbourhood driveway snow shoveler), my hands are often exposed to 0C to -15C temperatures for prolonged periods during the winter. It's reassuring to know that I'm sooner to die in frigid climates than my ring

lol, I'm just seriously absent minded sometimes. I was pretty sure the ring would be fine after the other things I've done to it (24 volt welded it to a truck by accident while wearing - hot, and exposure to RF radiation around the 20 kW range to name a couple).
I was more upset about the wallet and cigarettes that were in the same pocket. And glad my phone hadn't gone in there too.
