EN 13445
EN 13445
(OP)
The CEN website has announced that this standard (Pressure Vessel Design) is now available. However, BSI have stated that the standard is still in draft form.
Can anybody please clarify this.
Also, has anybody seen it yet? Is it any good ?
Comments gratefully accepted.

RE: EN 13445
I haven't used it or investigated it yet, but if it follows the line of the piping code (prEN13480) you can roughly assume that it consist of sections adopted from other codes, e.g. ASME VIII, BS5500, some DIN standards etc.
Furthermore it is probably full of typing errors and inconsistencies, because variable syntax differ between the codes it was copied from.
(Probably not very helpful)

I talked to the(my)national publishing company for standards. And they told me that EN-13445 and EN-13480 will be ready for sale in august this year.

I attend one workgroup days of the new european standards of pressure vessel the prEN13445 series last year and it seems that it will take few years before adopting them.
Keep in mind that it is a DRAFT and lot of manufacturer are surprised by the harshness of these standards. I don't think that it will be published as official standards in spite of the declaration of some national bodies supporting them.
I found lot of divergence between these standards and the other international and national codes (the ASME and CODAP code for instance).

RE: EN 13445
You're quite right, one of the things that amazed me however was the BSI published prEN-13445 as a consultation document and so the time lag was a little excessive (in my opinion).
Anyway, sections of the code are now avaailable, EN 13445-1,2,4,5,6 & 7.
EN 13445-3, the design code, is still a proposed standard and open for comment. Marvellous.

Well well, great news.

RE: EN 13445
Quite right, BSI now have the full code for sale.
I've seen a couple of pages and it looks like Merkblatt in disguise. Great if you use Merkblatt (and Stoomwezen isn't too disimilar) but not so good if you use PD5500 or ASME VIII Div.1.
Never mind we'll see what it's like when we read the full spec. The most interseting bit will be Annex Z to show where the code covers the Essential Safety Requirements of the PED and the materials (of which non are harmonized yet for the PED).

I think that lot of Manufacturer will be in trouble ! Some commonly used welded joint configurations are prohibited like butt weld with one plate edge offset (ASME WIII-1 UW-12 by instance) for T > 120°C. This joint type is widely used in Europe. For air service, it still accepted. But for applications like handling condensate, it's prohibited.
I'm surprised how speedly the standards were adopted. I think that the directive 97/23/EC will have an addendum to force using exclusively the EN standards. In 2000, EAM application for some steels were on pending because of lack of procedures. Suddenly in 2002, all the EAM applications were rejected ! It goes very very fast !!!!
We don't know if the "standard"gays realize the impact of what they are doeing !
RE: EN 13445
There isn't any requirement to use EN13445 and to this stage we have stayed well away from it. EN13445 is as restrictive as AD Merkblatter and is really a way of generating income for the likes of TuV.
EN13445 also makes requirements for impact testing of austenitic stainless steels without any indication of when this is required. Austentitic stainless steels are cryogenic materials and the only specification to reuiqre impact testing before was AD Merkblatter. Even the PED has issued a guideline saying that impact testing is only required when brittle fracture is a design consideration.
Impact testing is also now required of all austentic weld procedures, which means that all EN-288 weld procedures will have to be retested.
Somebody needs to get a handle on this.
RE: EN 13445
I think it is moving fast because the committees may be staffed primarily with theoretical types , and not neccesarily represented by fabricators or OEM's. A stroke of the pen, and voila! - everything is improved.
RE: EN 13445
If they are good or not I don't know yet.
