Definitions for "Shore hardness"
To be understood as the Shore hardness is the resistance exercised by the test material to a body of defined shape being pressed into it under a defined spring pressure (DIN 53505), Shore A for soft rubber, Shore D for Ebonite/hard rubber
A measure of the hardness of a material obtained by measuring the size of an indentation made in the surface under a known load. Other indentation methods such as Knoop, Rockwell and Vickers are also used. It is exceedingly difficult to convert hardness values obtained by one method to another.
A method of determining the hardness of a compressible material. Applies to photopolymer plates and non metal rollers on the printing press.
