INSPECTION CERTIFICATE of finished ASTM A335 Grade P36 forged bars
A type 3.2 inspection certificate according EN 10204 [13] shall be issued by the material manufacturer for the products. The inspection certificate shall include:
Type of steel making process
Chemical analysis of melting charge
Mechanical test results
Heat treatment conditions including used temperatures
Hardness test (actual hardness value shall be reported)
Report of non-destructive testing (scope according applicable test standards)
Conformity of the product with this specification and order requirements
The inspection certificate is a “documented information” according ISO 9001 [14]. For all documents a document number, a revision status or an index number, a page number and the total number of pages are required. If there are other test records linked to the inspection certificate, e.g. records of non- destructive testing, reports of material laboratories or other documents, these test reports shall be included as appendix in the inspection certificate (including their document number, revision status or index number, page number and total number of pages).
For issuing of the type 3.2 certificate according EN 10204 [13], the following shall be considered:
The manufacturer of the material must be hold an accreditation as material manufacturer according PED 2014/68/EU [1], annex I, chapter 4. The manufacturer´s authorized inspection representative shall be independent of the manufacturing department.
The required third party inspection agency shall be accredited as notified body according PED 2014/68/EU [1]
