I guess i need to pay for that. We once asked a price for CE brand on a whole pcb… this was over 10.000 euro. So dont think that i can add that to the price off a steering valve… but i know and like your idea.
Is the CE marked not just self certified?
Usually it’s a certificate signed by company director declaring all relevant legislation to the product is complied with.
There’s meant to be documentation to support this but this is only needed if requested by a relevant authority.
is there any better way to explain my notion of “overcroweded” ? 
@Raycorp , what’s your command of German?
When it goes to think in feeding law-thinkers, I’d prefer my mother tongue…
And what’s the proper tool for co-editing tables?
OpenOffice Writer?
I know all parts used by Hydac are CE certificated.
Dont want to sound harsh , but i dont have the time to continue with this. And not planning on doing those certificats.
No harm intend and i like your ideas. But if i would sell a 1000 valves a year i would think about it. It already cost alot of time to get Hydac in and develop a valve. And also costs are involved. So for me this is it.
Hope you understand
Think of a judge acting as a turing machine, playing “Schwarzer Peter”.
(Leo.org translates this German Game “to leave someone holding the baby” or “to pass the buck”).
He always will look either for and “end mark”, like “admission void” or “responsible person found” or for an instruction to move.
For a boss, the very reason for existence is to take responsibility.
This is risky, as life is. That’s what you try to charge margin for.
You always have to take care to able to answer, just in case such a turing judge knocks at your letter box.
The Guy offering CE certification does not take part in the game.
He does not take responsibility (I suppose).
He only prepares an answer for the for the case a judge were knocking.
The whole CE thing is skd of a subroutine for the judge.
“Ah, I see, certified by Boss XY, so I know whom to pass the baby”
At the end of the game, the judge knows whom to call to the bar, when Grandma Fisher was crunched by a tractor.
The driver, the farmer, the mechanic installing the system, the supplier of the valve block and the PCB, the author of the software, the producer of the valve, …
In the end, they all have to be prepared to answer and supply reasonable proof that they did a proper job did not violate any law that might have caused poor Grandma Fisher’s tragic end.
Sound terrifying, but that’s the game you enter as soon you’re starting the engine of your car or even your tractor.
I understand.
presumably that’s why they all are doing “§21”, means certification on the individual machine.
So “the baby” stays with the farmer (where it is anyway) and not passed to the supplier of the valve block. The block is sold with an imaginary (or real) sticker “not certified for use on public roads”
Nevertheless the community may supply assisance:
As I did with the pneumatic brake on my GT:
These were ordinary brake parts, most of them used.
So no involvment of suppliers.
But the cert clerk sees “ah, Compressor from WabCo, Valves from Knorr”
installation looks sound.
There are established circutiry around to follow,
He mesures the pressure at the outlets and does a simple funcion test - that’s it.
I don’t see whe as a community we cannot get to that point.
