If there is a paper glued to cctv camera that is hot (continuous operation)... can the paper just combust? what temperature can it do that?
Yes, it can catch on fire if it is hot enough. The temperature you're looking for is called the "autoignition temperature" and Google will find values for many common substances.If there is a paper glued to cctv camera that is hot (continuous operation)... can the paper just combust? what temperature can it do that?
As a possible plot scenario, it's a bit tenuous. At the sort of temperature that a label on the outside of a box of electronics would need, the inside would be in flames and all the semiconductors and fragile components would have stopped working . Over 100C, your average component gives up and many will pack up at 60C. A short circuit inside the box could be a possibility but these devices are supplied with less than a Watt of power so it could destroy itself without heating the box noticeably.If there is a paper glued to cctv camera that is hot (continuous operation)... can the paper just combust? what temperature can it do that?
Vinyl electrical tape ( PVC or PolyVinyl Chloride), various sources show ignition temperatures about the same as paper, 430°F to 550°F.
If yoy are Really concerned, the 3M company makes Glass Cloth electrical tape. Won't burn.

The ignition temperature is not usually the main consideration when choosing tape for a job.If paper and electrical tape has similar ignition temperature.. then what is the purpose of using electrical tape to wrap wire connections when you can use masking tape to do it?
inside the cctv camera is an IC. I measured its temperature as 176 Fahrenheit or 80 Celsius.
Not really. Industrial temperature range is ambient from -40C to +85C, and automotive temperature range is up to +125C. There will be a temperature rise above ambient at the IC die of several 10's of degrees (depending on what the IC is doing), so it's best to look at the datasheet for the absolute maximum junction temperature, and the thermal resistance θja (from junction to ambient).without proof, I would seriously doubt that. that would be above the failure temp of most electronics except maybe military or space versions
Wikipedia suggest it should possibly be 450 Centigrade not Fahrenheit...Yes, it can catch on fire if it is hot enough. The temperature you're looking for is called the "autoignition temperature" and Google will find values for many common substances.
As an aside, "Fahrenheit 451" makes for a catchy book title but doesn't have a lot of scientific justification.
Ray didn't really get it that wrong. Wikipedia appears to quote a source that is an extreme outlier. 451 F appears to be close to the auto-ignition temperature of paper, when something ignites without open flame depending on the exact composition, but is considered to be about 30F degrees higher, around 480F. Time is also a factor. A single sheet of wood pulp paper may ignite in a 480F oven in a few minutes but a thick book wouldn't.Oh Noooo! So Ray got it wrong? Did he work on any Mars missions?
