Are DGX H6 EN250(A)?

[L2m]

I wasn't really thinking about DGX's product since they're based in the US and I was nowadays extremely lazy for anything that involved another country... However I just knew a friend of mine would travel to Florida very soon and had the chance to fetch me a full set of new regulators. And the DGX seems to come with a black paint which matches well with the rest of my gear!

I'm only concerned about if the DGX regulators are "officially" EN250 (and better also A) acreditted? And I believe DGX is well known for being self-serviceable, but would self-service render it non-EN250 compliant (I have received trainings before)? And would a service by a technician of other brands be okay given SGX has no official technician at all?

The reason is more to do with local regulations. I'm concerned if local dive clubs would impose restrictions on my regulators if they do not have EN250 due to insurance policies.

EN250, for sure, the “random” oems that exist on Alibaba even have that — Im quite sure the DGX would have it
The A part, good question — do you plan to dive under 4degC?

I doubt that the self service of any reg has anything to do with voiding the rating; well only in the sense that of you service it wrong it might deliver under that ; but that compliant through service I think is more of an ISO quality assurance thing; the 250 rating is achieved on the “model” and not every piece that comes out, and through its lifetime

Haven’t read the actual full standard to be able to weight in tho

After doing a little reading here is what I found: EN250A applies the octo delivers the same level of performance as the primary second and means the regulator can be used for the escape of both divers. I'm surprised as in my memory the difference between having and not having A is always cold water susceptibility. But I did recently also get a pair of old Apeks DST first stages, and they're NOT marked with A on their bodies - but it's diaphram and comes with anti-freezing packs! Whereas my Akuana Falcon 3 has EN250A but the manufacturer does not recommend use below 10C (despite it works well under 10C).

It seems to me now the "A" works more on the side of second stages.

Is there any website where you could assess the official document for EN250(A)?

The A std. cane out in 2014, so I think that might have been before that
I might have an idea where to/who can find the std.

EDIT: check this 1st post out Cold Water regulator standards

I belive: It's not that the A part certifies a 2nd stage; it cerifies an extra 2nd stage as part of the whole system... so the 1st stage has to be up for it as well

Probably you can’t claim the 250 or the A as a stage, but as a combo (of 2 or 3); I think SP has a table for 250/250A certifiable combos

If I stick-man figure analyze it casually: adding 2 250A rated 2nds to an mk2 (original not evo), which can't handle that flow rate, then the system wouldn't be certifiable to the A std. -- again, others are way mor knolegabel than me (at least read the actual std.)

below 10C (despite it works well under 10C).

I think there are chapters that specify “grades”
250A >10 is a “lower” requirement

Also, being certified to do it, and can, don’t reflect 1:1
It could be a matter of cost of the extra certification

Ok, After some digging
Yes, testing for A is for a system of 3 (1st, primary and Aux 2nds); Annex B.2

The temperature marking is how the standard is written, as in at least 10, but lower temps (when tested) can override it; sec 7.2
