The NoBo changed classification
The NoBo changed classification
(OP)
Hello people,
Are there some kind of reason the NoBo wants to change my classification
acc. PED 2014/68/UE for vessel pressure (medium: liquid, danger (flameable); V=50000l; design pressure: 3bar).
My result was Module A, named like: Internal Production Control, I marked CE but without NoBo in this case.
I know the last word belong to they but I would to know whether they can require change to higher module D?
Can I disagree with this at all? If I prepare classification correct then can they made a change?
greetings

RE: The NoBo changed classification
Not that Im aware of. You, as manufacturer are allowed to do that; when you have to use module A, you can always go for a higher module, but never the other way around (AND, youre not allowed to affix CE when the item under consideration does not fall into any of the 4 categories, because technically you use module G for an item falling under "Sound Engineering Practice").
I get the same when using 50000 ltr and 3 barg.
No and no:
1. They dont have the last word, they can make mistakes. You should always check their work, theyre humans as well.
2. And they cant require you to use a higher module just like that.
Yes and no.
Just make sure youre both speaking the same language; are you sure you both have used the same classification when it comes to your fluid? What are the details of the medium wrt contents, design pressure & temperature, etc.?
RE: The NoBo changed classification
Thank you! It's very helpful.
The thing is the medium come from China
and it is some difficulty, because in our market it is doesn't exist.
i have a meeting tomorrow with NoBo and we will talk
but I must prepare myself in order to don't make a misstake.
So again thank you.

RE: The NoBo changed classification
mw87, can you provide more (exact) details on the medium as per my first reply?
RE: The NoBo changed classification
vapor pressure for this medium in designed temp. for vessel presure are lower than 0,5 bar in designed temp. (confirmed by supplier).
So base on NoBo will not make any changes.
However without comfirmed vapor pressure for this medium it's very likely that they would have still reguired change the module.
thank you for your effort and interest. http://www.eng-tips.com/

Any chance you can share this?
RE: The NoBo changed classification
Module of higher category = OK , Module of a lower category = not acceptable.
Also important, PS<=0.5 = PED not applicable.
