ELI5: Explain Like I'm 5

Comparative Tracking Index

Okay kiddo, let me explain Comparative Tracking Index (CTI) to you in a way you can understand.

Imagine you have two toys, one made out of plastic and another made out of metal. If you put both toys in a very hot room, which toy do you think will melt or catch fire first? The plastic toy, right?

Well, CTI is like a measurement of how safe different materials are when they are exposed to heat. It helps us know how easily a material can catch fire, melt or become dangerous when it gets really hot.

CTI is measured by testing the material's ability to resist a high voltage shock when it's exposed to heat. Higher CTI values mean that the material is safer because it can resist more heat and electricity without getting dangerous.

So, think of CTI like a safety rating for materials like plastics or metals. It helps us know which materials are safer to use in things like electrical appliances, automotive parts, or anything else that might get really hot.

I hope that makes sense, little buddy!
