BSEN 10204 type 3.2 Inspection Certification With the introduction of new EC directives, such as the Pressure Equipment Directive (PED), there is an increasing requirement requi rement for materials to prove they meet the defined chemical and mechanical properties. This has led to the authentication of material certificate requirements under the standard BSEN 10204:2004. This factsheet gives more information about achieving certification under type 3.2 of that standard. Background In Germany, inspection documents (certificate types) were originally specified in standard DIN 50049. These definitions of material testing and certificate types were adopted for European standard EN 10204, first published in 1991 when certificate types 2.1, 2.2, 2.3, 3.1A, 3.1B, 3.1C and 3.2 were defined, which closely following the definitions in the German standard. EN 10204 was revised in 2004 and published as BSEN 10204 in October 2004 with a simplified range of inspection documents (certificate types). These now only include types 2.1, 2.2, 3.1 and 3.2. - Type 2.3 has been deleted. - Type 3.1 replaces 3.1B - Type 3.2 replaces 3.1A, 3.1C and 3.2 of the previous edition. This reduced range of options was designed to make the standard easier to understand and work with.

What is type 3.2 certification? Inspection certificate 3.2 “type 3.2” is defined within EN 10204:2004 as a “Document prepared by both the manufacturer’s authorized inspection representative, independent of the

manufacturing department and either the purchaser’s authorized representative or the inspector designated by the official regulations and in which they declare that the products supplied are in compliance with the requirements of the order and in which test results are supplied”. Industry recognises an independent third party inspection as fulfilling the role of “purchaser’s authorised representative or the inspector designated by the official regulations”. EN 10204:2004 defines the manufacturer as an “organization that manufactures the respective products according to the requirements of the order and to the properties specified in the referenced product specification”. Examples of a manufacturer are steelmaker, foundry, smelter, forge, pipe/plate mill etc. Therefore, true type 3.2 certification is produced by the manufacturer, with test results supplied. The independent third party inspector will have witnessed test results and verified the material’s identification and traceability.

 

 

How we can help you Lloyd’s Register offers an independent third party inspection role to manufacturers for type 3.2 certification. This involves visiting the manufacturer where the surveyor will identify the material to be verified. This includes a visual examination, sample dimensional checks and confirmation that the material is traceable back to the ladle chemical analysis, which may be in the form of a BS EN 10204 type 3.1 certificate. The traceable reference may be the cast ca st or heat number, test number or some other reference clearly traceable back to the ladle analysis. The traceable reference would normally be marked on the component by the manufacturer via indelible means, i.e. hard stamping, etching, stencilling or other indelible marking. Adequate material is identified by the surveyor for further testing, with the traceable identity transferred, including test stamp marking of the original piece. Documentation would be reviewed against specification for compliance with chemical composition, heat treatment and Non Destructive Examination. The Lloyd’s Register surveyor would also visit the test house (either a department independent of production within the manufacturer or a sub-contract independent nationally or internationally accredited test facility) to witness the appropriate tests (tensile, impacts, bend tests hardness, corrosion, structure, etc) as specified in the standard or specification and review the results obtained to ensure they meet the required limits.

Providing all the testing and examinations meet with the specified requirements, the surveyor would carry out a final visit to the manufacturer to verify that the material meets the “product specification” as defined in EN 10204: 2004, review and countersign their type 3.2 certification and inspect and hard stamp, or otherwise indelibly mark the material.

Material from a stockist Often in industry, the purchaser (end user) will order material from a stockist. The stockist may select material that has only been certified by the manufacturer using a type 3.1 certificate. As defined by EN 10204:2004, this certification has not been validated by the independent third party inspector. However, it is widely accepted that material covered by type 3.1 certification can be upgraded to material to the-intent-of type 3.2 by the stockist employing an independent third party inspector to “validate” this material. Lloyd’s Register offers an independent third party inspection role to stockists and intermediate material handlers or processors for intent-of type 3.2 certification and this involves visiting the stockist to identify the material to be verified. This includes a visual examination, sample dimensional checks and confirmation that the material is traceable back to the ladle chemical analysis which may be in the form of a BS EN10204 type 3.1 certificate. The traceable reference may be the cast or heat number, test number or some other reference clearly traceable back to the mill certificate. The traceable reference would normally be marked on the component by

 

 

the original material manufacturer via indelible means, either hard stamping, etching, stencilling or other indelible marking. Adequate material is identified by the surveyor for further testing with the traceable identity transferred, including test stamp marking of the original piece. Following confirmation of traceability the material certificate is checked against the intended specification to confirm compliance for chemical analysis, mechanical properties (tensile, impacts, hardness, bend tests etc), heat treatment condition, corrosion and structure requirements, NDT performed as determined by the applicable material standard or client specification. The Lloyd’s Register Group surveyor would also visit the test house, normally a subcontract independent nationally or internationally accredited test facility to witness all additional testing of the material that is applicable. Providing all the testing and examinations meet with the specified requirements, the surveyor would carry out a final visit to the stockist, to review documentation (including the original manufacturer’s type 3.1 certificate), verify that the material meets the “product specification” as defined in EN 10204:2004; countersign the stockist’s certification and inspect and hard stamp the material The acceptability of the type 3.2 (or meeting the intent of 3.2) should be confirmed with the purchaser before work starts.

 

 

In both cases described above, Lloyd’s Register surveyors responsible for the third party inspection can, at the client’s request, issue inspection certificates that detail the scope of inspection carried out and include a statement of conformance with EN 10204:2004 or the intent of EN 10204:2004 as applicable.
