I has a local ski shop mount new Marker Griffon bindings on a new pair of skis for my son.
According to the DIN chart, they correctly came up with a DIN setting of 7.
When I picked up the skis, they told me that they set the front DIN to 8.5 and the rear DIN to 8.0. They said that they measured the torque range (also on the DIN chart), and that they set it to the correct torque, and that the DIN's were off by 1.0 to 1.5. They said that DIN indicators on bindings are not that accurate and that the appropriate thing to do is adjust by torque settings. I do not disagree with setting by torque values - if done properly.
My question is: Is this true ? Can DIN markings really be that far off from the actual torque values? Could it be that there is an issues with the bindings ? Is the Technician possibly testing torque incorrectly ? Could their Torque wrench be out of calibration ? Should I have someone else verify the DIN vs Torque setting ? Should I be calling Marker ?
Thanks in advance.
