I was part of the TC61 MT that did this work for the Commercial Cooking Equip. There are a number of zones called out, Non-functional hot surface and Adjacent surface. I recall there being at least one more term but it escapes me at the moment.

So in ovens, stovetops, griddles, toasters, heat-sinks, etc. do not require them. However, if such appliances or device have areas that are hot but it is not obvious it is hot, a warning symbol might be required. At home, I have a 2-slice toaster. It is a "Cool Touch" toaster that has no hot exposed surfaces, except from the small surface between the two slots on the top. So the manufacturer engraved the symbol on the metal surface. Not a bad idea. But back in the day, the sides of a toaster got really hot; hot enough to melt the Wonder Bread bag. As a kid, I think every toaster I ever saw had a Wonder Bread bag melted on the side.

Common practice is black colour on yellow background or white colour on black background. * Is an embossed sign black on black considered as a legible sign in EU criteria perspective? * In case of ink-printed label, is it put on the top of the hot surface or next to the hot surface? If on the top of surface, the colours are protected from heat degradation and specialized adhesives should be used to withstand higher temperatures. Is there any test criteria for verification?
