Oops sorry, didn't see your post Rskm. is a scale for measuring the hardness of elastic materials. It's basically the opposite of the scratch hardness scale that puts diamond at the top of the hardness list.

The Shore scale is a way to classify how much soft materials indent (aka "give") when they're compressed. It's divided into "scales" that differentiate really squishy materials like Nerf darts, from hard rubber materials like car tires.
