Companies dealing with the manufacturing of semi-finished casting products such as sheet metal, strip metal, pipes, forgings, castings, fittings or finished mechanical components (nuts and bolts, flanges, etc.) and wishing to market their output need the have their products certified by a notified third party body.
TÜV Italia can address the following areas:
- activities requiring the involvement of a third party body (T.P.I. Third Party Inspections);
- testing and certification of products used chiefly to manufacture boilers or pressure vessels pursuant to European Directive 97/23/EC (PED), which TÜV Italia carries out either through its Italian notification No. 0948 or through the TÜV SÜD mother house’s notification No. 0036.
- The involvement of a Notified Body is mandatory for obtaining a Certification, either in the cases regulated by the Directive or whenever required by the selected manufacturing code (e.g. AD 2000-Merkblätter for pressure vessels or TRD-Technische Regeln für Dampfkessel for boilers, etc.).
- In some cases (testing of products used in connection to manufacturing codes which have not yet been harmonized with the PED Directive) the Control and Certification Body must necessarily be TÜV Italia.

Both mandatory and third-party tests are performed in three steps described below, normally with the presence of a TÜV Italia expert.
This step takes place at the manufacturer’s premises and includes review of the following documents:
- order documents;
- specifications and technical drawings (if any);
- analytical compliance of the material;
- state of heat treatment and finish;
- results of any non-destructive tests, etc.
In compliance with the applicable regulations or specifications, this stage includes the assembly of sample units, identification of samples to be collected and the application of the stamp, which shall also be applied to the test tubes containing the samples. Before performing any tests, the inspector shall check that all test tubes are duly stamped.
Tests are performed at qualified laboratories or at the manufacturer’s premises if equipped with adequate testing facilities. Type tests and their number are determined upon sample collection and generally involve the following:
- room temperature and hot tensile tests;
- when required, non-destructive and anti-mixing tests.
Other tests may be required such as analytical tests, micro- and macroscopic examinations, corrosion tests or other technological tests. The presence of a TÜV Italia inspector is generally limited to mechanical tests.
This step takes place at the manufacturing company’s premises and involves the collection and checking of all necessary documents including:
- the manufacturer’s certificate;
- test reports from any external laboratories;
- certificates or records of any external processing, such as for example heat treatment, etc.
- Through visual and dimensional controls, TÜV Italia ensures that all required tests and verifications have been performed and have yielded positive results; in addition, TÜV Italia verifies compliance to marks and, if required, proceeds to apply the inspector’s stamp to the products in question.
Once all tests are completed, TÜV Italia issues a certificate.
- The certificate has no expiration and accompanies the related material throughout its life.
