HA, or Hardness Absolute, is a hardness measurement scale used for very hard materials like ceramics, where traditional scales like Rockwell or Vickers might not be suitable. It measures the material's resistance to plastic deformation by pressing a diamond cone into the surface. The higher the HA number, the harder the material.

Why pH is 10 for finding the hardness of water .something related to protonation?
A pH of 10 is often used when testing water hardness because it ensures that all carbonates and bicarbonates present in the water are fully ionized, allowing for accurate measurement of the total hardness. At this pH, the calcium and magnesium ions in the water form insoluble precipitates, which can be quantified to determine the hardness level. The high pH also helps to minimize interference from other ions in the water on the hardness measurement.
What is the limitations on the thickness of specimens for hardness test?
The thickness of specimens for hardness testing should generally be at least ten times the depth of the indentation created by the hardness test method. Thicker specimens may not allow for accurate measurement of hardness due to potential effects of surface irregularities or variations in material properties throughout the thickness of the specimen. Additionally, thinner specimens may not provide enough material for the hardness testing equipment to produce reliable results.

How much hardness can be acheived in EN31?
EN31 is steel that has a hardness measurement of 63HRC. The Brinell-Rockwell hardness of the material ranges from 59 to 65.
What is the scale for the Mohs hardness scale?
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
When writing hectares what letter do you use?
The unit of measurement for a hectare is abbreviated as "ha".
