During a recent audit our Notified Body told us that in order for a material manufacturer to be qualified to issue a 3.1b cert for pressure bearing materials he must also hold a PED certificate number besides being ISO certified by a EU recognized registar.

Has anyone else run into this interpretation?

Recommended for you

According to the PED ,in order to be allowed to supply 3.1B
you shall have an by a Competent Body approved Quality system and have undergone a specific assessment for materials.
Probably your NoBo referes to this last part.

Snoop02,

I'm afraid that your NoBo is not really wrong in his statements. I do not know in which part of the world you are located, not whether you are a manufacturer of pressurized equipment, or material to be used for pressurized equipment to be covered by the PED.

You will probably know that, at the start of the PED no to little materials covered by harmonized standards, or those approved of by the EU, were available.

The situation is now alterating, and such materials are available, and the requirements as set in the PED are taken more strickly.

Please see the PED, which is quite clear on this subject, for details. Please find a hyperlink added.


Kind regards,
Jalink
 
I'm an inspector of a NoBo in Spain (not TUV) and I agree Fawkes.

However, My technical directorate and I have the same problem that Snoop02 with ENAC, which is the national certification and acreditation company that audit us. They state that we must ask for Quality System stamp in 3.1B certificates.

We in Spain have an added problem with translation. While in english version sectión 4.2 ask for "particular material appraisal" and section 4.3 for "specific assessment for materials" in spanish translation both 4.2 and 4.3 ask for "
"particular material appraisal" (evaluación específica de materiales)

For me is quite clear.

1) Section 4.2 of Annex I is related to the standard of material and it gives three options.

2) Section 4.3 is related to certification of materials and the manufacturer's responsability in deciding if this certificates are correct or it is neccesary to perform further exams.

3)Section 4.3 is applicale to all materials of section 4.2, even if harmonized

4)"specific assessment for materials" is related to a quality system in which those materials are within the scope of the QS. (manufacturer may do another products not under de PED or even not for the apliccation of that section)

5)According to annex III the "particular material appraisal" must be performed by manufacturer and when applicable by the NoBo which number is stamp (not another one. While are guidelines for accepting welding procedures and welders from another NoBo, there aren't this guidelines for any other part of modules)

All said is so because;

1) There are TUV certificates that state that materials from a manufacturer comply with section 4.3 of PED (OK. For a material manufacturer is not enought to have a quality system. That QS must be for the materials certified. So in the material certificate besides QS stamp it will be neccesary to state that material is under this specific assessment. Unfortunately this is not common practice)

2) In those TUV certificates are inclose ASME materials (OK. What TUV certificate states is Quality system for that material is good and anyone may trust manufacturer's certificate)

3) In any part of TUV certificates is stated that those materials comply with section 4.2 (OK, because is the manufacturer or the NoBo which number is stamped who must perform the "particular material appraisal")

4) If material certificate is 3.1B and material manufacturer don't have QS, Where is stated in PED that equipment manufacturer and NoBo can't trust in that certificate? What PED says is that manufacturer don't have any responsability if that is so.

Sorry and Thanks for the lecture. Any comment is wellcome.
Quite a lot of problems with materials.
