View Full Version : Mueller-Hardness-Index (MHI)

Hi there,

Can somebody tell me more about the "Mueller Hardness Index" (MHI) for categorising the hardness of cue tips. I haven't found any description of the methodology in the net.

1. Which person has created the index and in which year?

2. How was the technical way of measurment ?

3. What does the data mean (exempli causa "60,1" for Elk Master tips), what is it for a unit of measurement?

4. What is the specific content of the MHI?

Thank's in advance for reply and best regards.

I don't have the answer, but a Google search came up with this interesting site:
web page (http://http://www.wolfbite.com/tip-selection.htm)
This does have some info, along those lines....

Thank's; i know this site. But there is no explanation about the method and the content of the MHI.

Why don't you just contact Mueller and ask them? /ccboard/images/graemlins/confused.gif

If you find out anything, please let us all know.

I have always just taken it as a very general guide line of which tips are harder than others. If I am familiar with one tip, it gives me a general idea of how another tip ranks against the familiar tip. Even if I knew the technical backgroung of the measurement, I wouldn't take it as absolute fact.

Hi Rich R.,

i contacted Mueller, but he gives no answer. That is the reason i ask here.
