Different golf ball brands and models offer different feel, spin rates and trajectory characteristics, and it's important to know which ball (or type of ball) is the best fit for your specific skills. Fortunately, golf ball manufacturers offer a vast array of products designed to meet an equally wide range of players.

The result is that on a hardness scale ranging, for example, from zero to 60, we allow for +3 to 2 points, a total range of 5 points; and if the hardness being measured is above 60, we use the reverse. In that case, our acceptance criteria are 3 to +2 points. That's still a range of 5 points on the hardness scale.

Hartford conforms to precision ball standards (including ABMA Standard 10, ISO 3290 DIN 5401) that dictate the industry standards of precision balls.
Ball Hardness Results The ball coefficient, k, is presented as a function of incoming speed in Fig. 4 for n = 1 and n = The response appears nonlinear, where with n = 1 the coefficient, k increases with speed (although at a slower rate than the force).
Rockwell Hardness Scales Reference Information and Standards In theory Rockwell hardness scales are to be selected based on the correct range and the combination of highest load and smallest diameter that will provide a good result without violating the minimum thickness, round correction, or other limitations, like case hardened samples.

Durometer Shore Hardness Scale. For example, you would not choose a rubber with a durometer of 70A to make a mold of a plaster standing ballerina with thin, protruding arms bent at opposing angles. A 70A rubber (as hard as a car tire) is stiff and would not offer enough flexibility to .
10mm Ball 150kg Brale 100kg 1/16" Ball . Diamond Pyramid 120kg. Tensile strength (Approx) Reference table: Steel Hardness conversion chart. Since the various types of hardness tests do not all measure the same combination of material properties, conversion from one hardness scale to another is only an approximate process.
The 45N scale employs a 45kgf load on a diamond coneshaped Brale indenter, and can be used on dense ceramics. The 15T scale employs a 15kgf load on a 1 ⁄ 16inchdiameter ( mm) hardened steel ball, and can be used on sheet metal.
