Road vehicles engineering I’d use TUV since they’re the dominant notified body in Germany. When used at the temperatures indicated and with a working period of h, no intergranular corrosion occurs when tested according merkblayt this AD Merkblatt. If not specified in the order, the manufacturer specifies the welding procedure. I asked the question in another posting but really this is a second discussion so I think it deserves a separate thread. Asking the customer would be a start but this is actually a product being merkblxtt for a handful of different German customers in response to some laws being past in Germany but later something we really would merkblagt to sell all over the world.

Adam – About years ago I launched an effort to understand the 200 rules in Europe. If above-normal loadings are to be expected during the operation of the pressure vessel, this shall be taken into account by meeting special requirements. Mechanical properties of bolts and nuts made of steels as specified in 2. There are 2 major laws in effect in most of the modern world. It just means that its use doesn’t infer automatic PED merkblart. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.


Providing a standard such as Merkblatt and or has been harmonized in other words ensured to meet all higher PED requirements the end user can actually size a valve to any standard formula of his choosing?

A copy of the high-level PED rules can be obtained for free on their website http: The minimum value to be adhered to shall be agreed with the material manufacturer. Join merrkblatt peers on the Internet’s largest technical engineering professional community. Responsibility for testing is as specified in the provisions of the relevant sector of the law.

I am currently working on a project being developed for use in Germany and we need to size out the relief merkblatg.

Regardless, a lot of engineers continue to follow legecy practices even though the rules have changed. Harmonized standards are the new standards that have been developed with representation from all EU countries, and once finalized, each EU member country is required to adopt those standards as national standards.

Steels conforming to SEW are tested according to the above standards depending on the product form. Welded tubes are those manufactured by qualified, mechanized welding procedures in continuous production from merkblaft or in series production as a single length from lengths of strip.

BTW, the quote from Wiki is specifically referring to pressure vessels.

For welded tubes3the procedures and personnel for manufacture and testing by the relevant third party shall be confirmed. Refer to the comment above about formulas. I don’t have a clear answer, but I do know that they are still very widely used in Europe. A harmonized standard e. Regardless, i think you can figure it out. As such since the PED does not give formulas or direction on actually calculating particular sizes etc The CE stamp is one that the manufacturer’s must obtain in oder to sell products in the EU market.


If an inspection certificate 3. There have been developed that are still used hesitant European harmonized standards for pressure vessel standard series EN Tubes or nozzles manufactured individually do not come within this definition. Really what I am looking to do is come up with a design that hopefully is good to use anywhere in the world but specifically anywhere in Germany.

It’s just human nature to resist change. By using a harmonized standard, one is granted the automatic presumption of compliance with PED. I think at this point the better ones to talk with will be with our notified body who will be issuing us the CE mark as opposed to customers but we will zd. When it comes to using a standard to work towards the PED the engineer must be careful that the standard in use is harmonized with the PED.

Personally, I like the application standard EN In conjunction with VdT?
