PED Material Certs
PED Material Certs
(OP)
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?

RE: PED Material Certs
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.
RE: PED Material Certs
Your quality system needs to be approved by a competant body registered in the EU, there is NO requirement for the meterials to hold a PED number.
If you know that this is happening contact your local minisyrt or government department (in the UK this is Mike Dodds at the DTI) and report it.

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.

The detail originally mentioned relates to the essential safety requirements. There is no need for the material manufacturer's quality system to be approved/appraised in accordance with the directive.
Section 4.3 of Annex I states:
Where a material manufacturer has an appropriate quality-assurance system, certified by a competent body established within the Community and having undergone a specific assessment for materials, certificates issued by the manufacturer are presumed to certify conformity with the relevant requirements of this section.
Clearly stating that if their quality system is certified by a competant body and having undergone a specific assessment for materials that this is OK. The specific assessment does not relate to the PED but relates to the relevant ISO quality standard.
Some notified bodies are conning clients into having supplemantary assessments, I stand by what I said earlier, the national bodies that control these issues have all agreed that the definition I have provided is correct and I would urge anyone to contact their national body if they are being pushed to gain additional assessments.
As a further point, it is very rare that any of the 'haromonised' material standards provide compliance to the PED either, if you check out the PED website (see FAQs) then you will find that most of them have qualifying statements in relation to their use and assumed compliance to the standard.

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.
