The New Dive Rite Optima CM - My 30 Hour Review

[jale]

What fight? We're all stuck at home with absolutely nothing to do. If we're not discussing rebreathers what else are we going to do? Look at porn?

What is wrong with society when every discussion is perceived as an attack?

Just a figure of speech but you want to figure the figures

Just to note that EN testing is conducted between the test body and the commercial entity/company. Its not a public process. Its also an expensive one, circa €500,000, and if your unit fails, its embarrassing for that company. For these reasons and others, some manufacturers don't bother going into the European market.

That all makes sense. I infer that you are saying there is no registry of units that have received the certification, where one can look at the details of the test results?

How would one know if someone claimed CE certification but did not really have it? Is it that you CAN independently verify that the unit passed certification, but not the details? If that is the case, how do you verify exactly what configuration is certified?

I totally understand why the results of failed certification tests would not be public. I guess I don't understand how the process works, or even COULD work, if the process does not result in publication of the details of any certification that passes. How can you trust the certifying body if all they tell you is "yes, it passed" without any details beyond.

"Ignore the man behind the curtain!! I am the great and mighty Oz!!!"

Also, are you in agreement with others that the certification in question contains a requirement for automatic O2 injection? If so, do you have any idea how the Triton was able to obtain certification that it met that requirement?

It may be as simple as semantics. A constant flow of O2 is "automatic", i.e. it doesn't require action on the part of the user.

yes must be as simple as that

yes must be as simple as that

I postulated that earlier. If that is the case, then I wonder at the earlier assertions that other manual units that also have a constant flow of O2 have been denied certification because they do not have "automatic" O2 injection.

I don't know if it is related but the Triton valve is fed by two hoses from the first stage

I can not definitively say, but achieving the standard is such a big commercial deal that if you attempted to fraudulently claim you had passed it your competitors would quickly report you to the testing body, the associated training agency who conduct the training on the unit and the police for misleading the public and your customers.

Is it that you CAN independently verify that the unit passed certification, but not the details?

Again I am no expert but I would imagine in the interest of public safety if you had a concern over a particular product that claims to be CE certified, the testing body might be able to give you confirmation of whether it passed the test.

If that is the case, how do you verify exactly what configuration is certified?

If its satisfactory with you a quick email to the manufacturer would quickly settle that query. Hell, they might be even reading this thread and if they do I'm sure they might chip in, otherwise send them a mail, especially if your interested in purchasing one. As a potential customer they will be only too happy to provide with whatever info your after about the unit.

I totally understand why the results of failed certification tests would not be public. I guess I don't understand how the process works, or even COULD work, if the process does not result in publication of the details of any certification that passes. How can you trust the certifying body if all they tell you is "yes, it passed" without any details beyond.

You can trust the certification process as its requirements clearly set out in its own documentation and index here. Its a European standard and this is my country's edition of it. Hopefully the index gives you an idea to how rigorous it is and also how it is not 'partisan' as some have claimed in this thread!

Well, do we really know that? It's no joke above that cmf/leaky valves and orifices can't get CE. So, what pockets did Triton grease to get it?

What was stated above about CE cred might be true.

Just turn up the pressure on the orifice and there's enough flow so the diver does have to do anything?

No there's no public list of CE anything. Nor any requirement to actually publish your results.

In fact there's a whole fraudulent industry behind CE and a "competing" mark which is intentionally ambiguous. That's the Chinese export version of CE
How To Distinguish A Real CE Mark From A Fake Chinese Export Mark

There are CE cylinders mysteriously certified by some guy in an apartment in (?) Sweden, that were sold for years by Sortis for instance.

The whole problem with CE is that 1) its stupid expensive, 2) its not a public process at all, 3) people put a whole lot of faith in it's validity which makes it a valuable thing. So consequently there's a ton of fraud around CE. In part because its a crazy, expensive, proprietary process that pretty much couldn't be more ripe for fraud.
