One of the bindings i ordered was set at 14 DIN—how do i even the springs strain out?

When i opened up the box and checked my bindings DINs, one was at 5 and the other was cranked way up at 14. When i lowered the 14 DIN binding back to 5, it was much easier (less resistance) to pull the toe clips apart on that binding compared to the one that came out of the box with its DIN set at 5. So its pretty obvious that the spring on the binding that came with its DIN at 14 must have had some strain (fatigue) from all the time it spent sitting in the shop with its spring compressed so tight.

My plan is to take the toe piece that came out of the box with its DIN at 5 and crank it up to 14 and leave it for a few nights. Then i will bring its DIN back down to 5 and compare it with the other one to see if the springs feel closer together in strength. And then if its still not even i will repeat until the bindings both feel the same spring force at the same DIN.

does this sound like a good plan?

Dont worry about it. even at 14, that thing isnt compressed much.

Do you think if i just set both toe dins at 5 the springs will readjust back to normal so they are both evenly compressed? Because pulling the toe clips apart there is a big difference in how much resistance each toepiece provides when i set them both at 5.

Are these new bindings?

They were listed as new yes but to me its pretty obvious they were used at least somewhat.

its pretty obvious skiing requires to much thought and a lack of intelligence on your part is making it way fuckin harder than it needs to be
just snowboard

I’m going to assume you will not be mounting these bindings yourself. If thats the case, a shop will mount them and then test the consistency of the release value using a calibrated tool, if theres a drastic difference between the two the shop will notice and there is a range they are allowed to adjust them in, usually plus or minus 2 dins, if they fall outside that range then the bindings fail the test.

It seems like 95% of ski binding threads on here are complete paralysis by over-analysis. Jut take em to a shop and get them release tested then ski em. simple

Its a reasonable question im asking you low iq tool. Springs fatigue over time.

“

Not as simple as that. Creep and fatigue both cause metals to undergo plastic deformation before reaching their elastic limit.

Creep occurs when metals are subject to a constant, long-term load before being unloaded (such as in storage). This is roughly the reason tool or hardware with springs are reccomended to be stored unloaded. Fatigue is the cyclical loading and unloading of a metal, and usually causes more localized damage/deformation.”

“The phenomenon in work here is stress relaxation. What it means that for a given applied strain (i.e. spring compression), over time the stress throughout the material will decrease, or relax. So in this case, yes the spring will relax some if it is held in the compressed state for a long time.”

I think they would both pass. Its just annoying that the vendor cranked one of the bindings dins up to 14 and left it that way.

Keeping a binding set at its highest setting or its lowest setting doesn't matter and it won't in any way damage your binding. The manufacturer did this probably as a quality check before shipping it out.

Like others have said, when you take them to a shop to get mounted & release checked, the shop will find any inconsistencies should they be present.

Don't worry about it. The bindings have gone through more testing at max-DIN than you can think of and they are safe to store that way too.

Yeah. Im hoping they just cranked the one toepiece up recently because stress relaxation of metal springs is definitely a thing.
I wouldnt care if both springs had stress relaxation evenly. I was only worried that if i set my dins equally on both toe pieces then one binding would be releasing more easily or less easily than the other.

And while your hypothesis might be true in general, it really doesn't affect the binding within the lifespan of the binding. Bindings are specifically tested for this and it's just not a real concern you have to worry about.

By the time it would become a problem for you, your binding would already be off the indemnified binding list and as such any shop wouldn't be allowed to work on it. It really is nothing to worry about.

Is there like a set age where ski shops cant work on older bindings? Like 15 years old or something?

No because all bindings are different. Some are made to be super cheap/first price point products (these are mostly made of plastic and will "die" earlier), while some are made to be ultra durable and last much longer.

Every year shops are given a list of bindings that are ok to work on. If a binding is not on the list, the shop is instructed not to work on it. So, shops always need to have updated lists and keep referencing them.
