Which of these are true about hardness testing?

Brunell Hardness is a type of testing to force a sphere of metal into a surface

Vickers Hardness is a type of testing using a diamond indenter

Hardness testing is often carried on materials after heat treatment

Hardness tests are measured using a combination of numbers and letters to create a value e.g. 3mm Sheet Steel could have a measurement of Rockwell C 71

Hardness testing is often carried out on materials before heat treatment
