Okay kiddo, do you know what temperature is? It's basically how hot or cold something is. We use thermometers to measure temperature, but when we want to measure the temperature of something really hot, like molten steel, we need special thermometers that can withstand high temperatures. These thermometers are called radiation thermometers.
Now, there's a group of scientists and engineers who work together to make sure that radiation thermometers work properly and give accurate readings. They're part of a bigger group called ASTM, which stands for American Society for Testing and Materials. This specific group is called the E20.02 Subcommittee on Radiation Thermometry.
The scientists and engineers in this group meet regularly to talk about radiation thermometry and how to make it better. They come up with standards and guidelines for how to use radiation thermometers correctly to get accurate temperature readings. They also test new technology and methods to make sure they work well.
Basically, they're like a team of superheroes who make sure that radiation thermometers work well so that industries like steelmaking, glassmaking, and semiconductor manufacturing can operate safely and efficiently.
