cdn.ymaws.comA typical water hardness test kit that uses water strips provides with each strip a color chart. Match the color on the strip (after you wet it with your test water) against the color chart to see the hardness of your water sample, measured in ppm or gains. A typical water hardness test kit strip measures hardness from 0-1000

imechanica.orgRockwell hardness differs from Brinell hardness testing in that the indentation size is measured in Brinell testing while Rockwell hardness is determined by the depth of the indentation made by a constant applied load. For thin test samples or samples for which the relatively large Brinell or Rockwell indentations must be

www.atri.edu.inThe hardness of a material by this Rockwell hardness test method is measured by the depth of Penetration of the indenter. The depth of Penetration is inversely proportional to the hardness. Both ball or diamond cone types of indenters are used in this test. There are three scales on the machine for taking hardness readings.
