Brinell Hardness Number is obtained using a perfectly spherical hardened steel ball of 10 mm pressed against the test surface using a static force of 3000 kg = kiloNewton for at least 10 seconds for steel and measuring the diameters of the indentation left on the surface by means of a graduated low power microscope The result is either

The Rockwell Metal Hardness Scales Explained

Comments 0 The Rockwell hardness test is used to test the hardness of materials The Rockwell test is usually performed on metals ranging from thin steal all the way to harder metals like Titanium However there are multiple scales to test in and these are identified by by a letter ranging from A V Each scale uses a different indenter and load to perform the test.

Rockwell Hardness Testing of Plastics

Rockwell hardness is generally chosen for harder plastics such as nylon polycarbonate polystyrene and acetal where the resiliency or creep of the polymer is less likely to affect the results The Ball Indentation Hardness test ISO 2039 1 DIN 53456 is used in Europe much more often than in North America.
