1. ISO 9462- Alpine Ski Bindings
2. ISO 13992- Alpine Touring Ski Bindings
1. The first, is what has been adapted and evolved every five years to apply to normal alpine ski bindings. It is the most stringent certification on releasability, durability, weather and material standards.
2. The second, is what has been developed to test tech fitted pin bindings. It covers a ton of the same aspects of alpine standards except for some key tests like location of release, elastic travel and unwanted release.
This is a quote by Dr. Irving Scher, the chairman of the American Society for Testing and Materials’ International Snow Skiing Committee, that describes the touring ISO standard 13992 well. He said, "Certification is not a measure of how well a given binding will perform during skiing. Certification means that with a very particular AT boot sole (from an ISO standard), the binding will perform in a manner that is desired to reduce the likelihood of lower leg injury. The problem is that the boots on the market do not meet, in general, the current international standards, and the pin inserts used in these boots are significantly different between manufacturers. With this in mind, at this time, any given set of boots in any given tech/pin binding may provide boot retention and release performance that is different from what skiers have gotten used to with standard alpine bindings."
This is a quote from Wildsnow that is further enlightening on the tech vs. alpine certifications:
"One binding is tested for consistency of safety release as the ski flexes. 20% deviation is allowed for side release, 15% deviation for vertical. I’m told this is the test many tech bindings can’t pass."
Esse
So essentially, what is being stated is that despite the Tecton being TUV/ISO certified, despite it having elasticity, it does not certify as an alpine binding and therefore doesn't meet the release capabilities that are guaranteed under the TUV/ISO alpine standard 9462. And thats not just the tecton, that's every single tech insert bindings...save the SHIFT. So despite claims of elasticity and travel, these are not certified claims. The Tecton may in fact be safer than many other tech bindings, but the SHIFT is certified to be as safe as the alpine bindings we're all used to.
