Dear Mr. Raja gopalan ,

Thank you for your reply .

As Impact test for B/M and PQR is exempted per UHA 51 (g) in ASME Sec VIII Div, 1, the ratio shows 0.20 only, for A 928 UNS 31803, 10 " 4.29 mm pipe, MDMT is -45 Deg C ( Equivalent Pipe is A 790 UNS 31803 was used for allowable stress per ASME Part II D )

Is it required to do Impact Test for PQR as per PED 97/23/EC for 4.29 mm thk pipe ? as we are going to do Impact test for pipe now.

Regards ,
Saravanan

Dear Saravanan,

Also as Mr. George mentioned, the testing requirements of EN 15614-1 like RT, MPI, HARDNESS etc. which are additional to ASME Sec. IX, are to be performed for the PQR test coupon

Thanks and Best Regards,

K.Rajagopal

Dear Gents,

Very Frequently we do these PED jobs.

Nasser Kunju is right as a whole. We had the instances of using PCN certified level II for NDT examinations and hence could not come across violations. I could not comment on NDT part. Except that Be it EN 15614 or ASME sec.IX, PED does not bother the construction code, where as NOBO/ RTPI Witness is a must,

Also, We have seen N no. of CE marked U stamp vessels and hence No contradiction what so Ever.

Also, please note that every material you use has to be supported with a PArticular Material appraisal compatible to harmonised ( EN based) Materials.

Thanks and Best Regards,

K.Rajagopal

PED is a directive only it is not design code.

Since you are going for ASME for the design and construction you need to comply with all ASME requirements plus additional requirements of PED.

PQR's should be witnessed/approved by RTPO/ NOBO even if it is as per ASME IX and Section VII Div. 1 . ( ASME does not require third party witness )

Welders to be certified by RTPO/NOBO. If welders have been qualified as per ASME but witnessed by a RTPO/NOBO it will satisfy.( ASME does not require third party witness )

NDT personnel to be certified by RTPO typically by BINDT etc which is a member of

European Federation for Non-Destructive Testing (EFNDT).

( ASNT does not require third party witness )

NOBO and RTPO are bodies registered in the European union. You can get the list of approved national bodies from this link

http://ec.europa.eu/enterprise/newapproach/nando/index.cfm?fuseaction=notifiedbody.main

Trust the above will help you.

Compliance with harmonized standards gives presumption of conformity.
However one of the basic principles of the New Approach is that harmonized standards are not mandatory!!!!
Please note that not all EN standards are Harmonized Standards

Hi Saravanan,

I think there're some mix up on this issue.

First of all if PED is the directive or the design basis document then all welding qualifications should be done as per PED directives and appropriate EN standards.

To my understanding ,requirements and acceptance criteria of EN-288 and ASME Sec-IX are not the same. The grouping of materials , required testing and acceptance requirements differs

If your vendor is trying to push the acceptance of ASME WPS and PQR , then a comparative spreadsheet must be provided to aid the AI, without which acceptance would put the

AI in liability or risk.

LR is one of the third party review organization, accepted worldwide. Hence the selection of LR as reviewer was not a problem, however acceptance of ASME welding WPS/PQR for PED designed equipments may not be the right choice.

Look at the 2nd attachment , clause 6.12 for qualification of welding procedures and 6.13 for NDE personnel.

The first attachment gives general overview of all EN standards.It's bit old, there may be changes incorporated in the standards.

Thanks.

Dear Mr.Veera ,

Thank you for your reply.

Whether LR to be from Europe as given in PED List of Notifiers, attached for your reference.

Or Even LR from ASIA is allowed to approve these procedures for PED.

Then for NDT personnel, can we use EN 473 qualified person for PED Jobs.

Dear PED Experts,

When I cross checked the requirements from PED 97/23/EC Annex 1 clause 3.1.2 & 3.1.3 for category III items,

the operating procedures ( WPS & PQR ) and personnel ( Welders & NDE ) has to be approved either by a Notified Body or a third party organization recognized by a member state as provided for in Article 13 from PED 97/23/EC,

But our vendor has already made WPS & PQR as per ASME-IX which was reviewed by local Lloyd's Register Asia in Korea without getting from approval either from Notify Body or a Third party third party organization recognized by a member state as provided for in Article 13 from PED 97/23/EC.

NDT personnel has been certified as per EN 473.

1) Are there any options to solve this issue to fulfill Annex 1 3.1.2 & 3.1.3 from PED ?

2) The below statement from Annex 1, Clause 3.1.2 mentions about Harmonized standard, please reply with explanations.

SARAVANAN,
