Sep 22, 2015Before you tackle the hardness of your water, you must first bring the pH and Alkaline levels into proper balance as the chemicals you use to balance these levels can affect your calcium hardness. If your water hardness level is above 400 ppm, you will need to lower the calcium hardness level, if it is below 200 ppm, you will need to raise it.

Mill Terms Mechanical Properties Tensile Strength—In tensile testing, the ratio of maximum load to original cross-sectional area. Also called ultimate strength. Yield Strength—The stress at which a material exhibits a specified deviation from proportionality of stress and strain. An offset of .2% is used for many metals. Yield Point—The first stress in a material usually

The greater the indenter surface penetration, the lower the ultimate Brinell or Rockwell number, and thus the lower the corresponding hardness level. Therefore, high Brinell or Rockwell numbers or readings represent a minimal amount of indenter penetration into the workpiece and thus, by definition, are an indication of an extremely hard part.
DIRECTIONS FOR USE OF POLDI HARDNESS TESTER MODEL "NP" Insert the tapered end of the standard test bar after cleaning into the space provided between the ball and the plunger and slide it further beyond the tapered position.
