How does the Mohs scale rank gemstone hardness? Why does the metal industry require more precise measurement methods, such as Rockwell, Vickers, and Brinell?

Industrial rubber typically falls within the 40–80 Shore A range, though there is no single standard hardness for all types; components such as gaskets, seals, vibration dampers, and rollers may utilize different hardness levels depending on specific requirements. Temperature also significantly affects measurement results: heated rubber tends to soften—lowering the Shore A value—while cold rubber tends to harden, causing the Shore A reading to rise.
