Certificates and Inspection Documents

Inspection and document requirements are reviewed before quotation so the project can confirm cost, lead time and acceptance requirements early. Our MTC 3.1 guide walks through a real 3.1 certificate line by line.

Certificate register: issuer, validity and PDFs

EN 10204 3.1 and 3.2: One Real Certificate of Each

EN 10204 3.1 is validated by the manufacturer's authorised inspector; 3.2 is additionally validated by an independent inspection body or the purchaser's representative.

Each certificate covers its own order only. A 3.2 is arranged when the order specifies it; it is not issued for every BLD flange.

Certificates on File, Each with Its Validity

17 certificates and approvals on file. Each row gives the issuer, the number and the expiry date as printed on the document, the scope it covers and the PDF itself; where the issuer publishes its record of the document, the row also links to it so you can verify it there.

Supplier System Registrations

These entries are records held inside a buyer's own vendor system. They are not certificates issued by a certification body, so they are kept separate from the certificate wall above and no certificate image is shown for them.

Vendor system registration - not a certificate

ADNOC supplier system - manufacturer listing under UAE representation

SHANXI BAOLONGDA FORGING CO., LTD is listed as a manufacturer in the ADNOC supplier system under UAE representation. Two flange product groups carry the status Pre-qualified.

Manufacturer
SHANXI BAOLONGDA FORGING CO., LTD
Facility country
China
Manufacturer ID
20036654
Agency type
Representation, through Fusion Engineering Suppliers L.L.C-S.P.C
Agency expiry
12 January 2028
Product group 160730
FLANGES & BLINDAGE - status: Pre-qualified
Product group 160744
FLANGES FOR PIPES - CS/AS/SS - status: Pre-qualified

Pre-qualified is the status field the supplier system shows for those two product groups, and that literal status is the whole of what it says. It is a vendor-system status rather than an approval issued by a certification body, it is held through a UAE representative rather than directly, and it carries no validity of its own beyond the agency expiry date above. No screenshot of the system is published here, because the source screen also carries the representative's own account data and an unrelated supplier's attachment.
