My View DIN is not just DIN
I was searching around for thoughts on bindings, and I kept seeing this comment: a "12 DIN is a 12 DIN."
Well, I worked in a shop as a tech many years ago, and bindings have changed very little.
The Look toe is the old Geze.
The current Marker, Tyrolia, Warden is a lot like an old M40. (Side note: I am curious as to why this winged cam design came back)
Sollys are the same.
I tested 000s of bindings in the 1990s. I don't think much of anything has changed.
DIN is not DIN.
Until you see how these bindings test as a combination of release, friction, and elastic travel you may not appreciate the difference.
My observations might be dated, but the designs are the same, or even becoming simpler (1990s backward twisting knee lawsuit frenzy).
Solly 747 style tested great, came out on DIN and showed elastic travel. Friction could affect release, but things generally worked very well.
Look Pivots with the ZR toe tested pretty well. Tons of travel, and the machine always needed a nudge to get them to release. A highly functional binding, but you couldn't tweak the spring to get a release DIN on the tape. DIN is not DIN.
Markers go CLICK. They tested on the numbers but no travel. The rep came and said, "DIN is DIN" so we are the best. No way I would ski a Marker to this day. There were no compromises for real world conditions.
GEZE - this is the the current Look toe. It tested all over the map. I thought I was highly unreliable for a DIN value, but had elastic travel. Release would get about 50% of the way there and nothing would really happen. This made it functional to ski, but DIN setting would be a guess. I used to send them out +/- huge amounts of tension to get them to test, before I realized this wasn't the design. The right way to test these was to watch the machine and when it required very light force, just pop them out by hand. Otherwise the binding would just stretch - the machine wasn't made for the toe.
With the elastic travel, I can see why Look would use the design today, but the DIN setting is an art, not a science.
The GEZE heel was scary - like a Marker toe for pre-release. I think Look is using these on low-end bindings today.
Tyrolia - I was testing the old 490s. These were like a bomb going off, and sometimes they would break. Very scary. I'm surprised they have a product people like today with the Attacks. I would start the machine and run for cover.
Today, I ski Look Pivots, Solly 747s (or STH), and a set of Wardens that have worked just fine.
But... I just want to go on the record that I really don't think "DIN is DIN"

My View DIN is not just DIN
Why do you think so many Mags like STH Salomon and P15/18 Looks?
You must have missed the whole frame binding thing, because that explains the design of the Warden/Guardian, Jester/Griffon/Duke/Baron, and Attack/Adrenaline...gotta change the design to let the toe piece pivot in walk mode.
DIN (or is it “Release Value”...all so confusing) ain’t rocket science...and most current bindings work just fine. Even Markers. YMMV.In constant pursuit of the perfect slarve...

Yes, I missed that about the toe piece. My frame bindings are Fritsches. They have skied 3 continents!
Of course, everyone likes Looks and 747s. This was the case before the internet was invented.

DIN is DIN--each number on the chart specifies the force needed to release the binding under standard test conditions. Doesn't matter who made the binding, the condition of the boot or the AFD. Technically a binding is set by adjusting the release torque to the value specified by the chart. The numbers on the binding are a starting point, not an endpoint although a lot of us use them as an endpoint.
The DIN scale on the binding may or may not be accurate. Even if the binding is mechanically perfect the binding maker doesn't know what boot you're putting into it or it's condition. My current STH's (brand new when mounted) have toes that test 1 number lower than the heels--the heels are set at the DIN on the chart the toes 1 number lower. No preleases yet.
DIN certainly doesn't describe all the performance features of a binding--elastic travel, durability, nor does it purport to.
I'm not a tech but I'm guessing toes are off more than heels, since toe release would be affected more by friction. Is this true?

Semantics: DIN is a German standards organization, just like ISO or ANSI. Your initial binding retention setting is determined by a chart approved by DIN. DIN is DIN.
The "12 is a 12" statement simply means that according to your height weight age skier type and boot sole length, your initial indicator setting will be the same regardless of make/model of binding. DIN is DIN.
Your retention setting may be adjusted during testing and calibration to ensure the binding will release within a certain range of force applied laterally to the toe or vertically to the heel. Your final indicator setting is determined by the amount of force needed to release the boot, which should be consistent regardless of what the final indicator setting is. DIN is DIN.
Side note: the M4/30/40 toe was actually way more complex than current laterally sprung toes from marker/salomon/tyrolia. The dual double pivot on the M40 changed tension by adjusting the length of the moment arm, and on release the pin holding the end of the spring slid in a channel to allow the toe wing to open. It was a pretty cool piece of engineering when you look at how simple the look Nevada-style toes of the day were. Current models are pretty basic, but IMO more dependable for it; the toe wing "cam" pivots and depresses the main spring, rather than pulling on it.
That's pretty accurate. But with today's bindings, I find it pretty rare to adjust retention by more than 0.5 to get it to fall in range. They're pretty damned consistent nowadays, as long as boot soles are compatible.

the fact that you tested fore the turn of the centurty with a pos overpriced torque wrench on a stick vermont
and you think it accurately measured relase values makes this still a tech 2 1/2 decades later

both montana and winterstieger make quality machines that measure release values in a consistent manner
with better quantifiable results vrs that which a shop rat, monkey , bum,stoner or professional tech than using variable user input outdated pos

DIN - as applied to alpine ski binding functionality - is just a set of standards (identical to ISO 9462) that every binding offered for sale needs to pass, and every customer who chooses to have a shop mount their bindings needs to agree to. The rating system for release values is intentionally conservative; it doesn't address the quirks that each binding possesses or whether a given skier can actually stay in the binding in the course of a given ski day and still have it release when necessary. How many people do you ski with who actually ski at their recommended setting, even for a 3+ skier?

PS Most people on this forum have figured out a binding model/release value protocol that works for them.
If a customer asks what they should set their bindings at, or if I ask them what they set their bindings at and they "don't know," I refer them to the chart - it's as good a starting point as any.

The current Marker, Tyrolia, Warden is a lot like an old M40.
Uh, no, the M40/48/Comp toes were twin cam and had +/- 10mm of lateral release at which point the wings opened up. I'm no fan of Marker but as others have mentioned coming here 3 decades later to spread your wisdom is kind of stupid.what's orange and looks good on hippies?

This is why the kids don’t get to use the adult tools. WTF is OP rambling bout? We’re all dumber for reading.

Is there any component of the DIN testing standard that accounts for ski flex? So if a ski is flexed and (presumably) forward pressure is higher than it would be on the bench, does the DIN standard account for that and require the release value to still be within some range?
