Here is some 'interesting' reading: http://www.vermontskisafety.com/ The shop I work in uses the Vermont Release Calibrator
Also, From Powder7: http://www.powder7.com/ski-bindings-din-chart/sizing-guide
The charts that we use in the shop also include the expected torque setting for specific DIN settings. I'll use myself in this example.
I am 58 y.o., 190 lbs, 5' 11", a type III skier with a BSL of 307 mm.
First you find the highest row (furthest UP the page) matching the height or weight. In my case that is L.
Since I'm over 49, move up a row. Now I'm on row K.
I'm Type III so move down two rows. This puts me on row M, my Skier Code. The initial calculation of row is for a Type I skier.
Now move over to BSL column 291 - 310 mm. Bingo. My initial DIN setting is 8.
Now adjust the bindings to DIN 8. Put in the calibrator and torque it. If the torque readings are between the values of the row above and below for my Skier Code, then the binding has passed. If the torque is too low, set the DIN higher and retest. Conversely, if it is too high, set the DIN lower and retest.
When I fill out the binding service form (the one you sign and waive your rights), I use the skier information (age, height, weight, type, BSL) to calculate the Skier Code. I enter the initial DIN in one box. After testing, I write the actual DIN values in individual boxes for the toes and heels, left and right. There are also checkboxes for recording the evaluation of the binding function and condition. This becomes the document the shop uses to protect itself. If an accident were to occur, we'd locate the ticket and verify that the skis, boots and bindings in question were the ones we had tested. From there 'it is a legal matter, baby'.
As far as I can know, the tables are identical from binding manufacturer to manufacturer and the variances accepted are the same (one row up or down).
