TÜV Italia - TÜV SÜD Group has embarked on a construction project to enhance the capacity of its laboratory by introducing three new electromagnetic compatibility (EMC) chambers. This strategic decision follows the successful completion of the semi-anechoic chamber in 2020, which stands as a prominent facility renowned for its size and capabilities.

Located in Volpiano (TO), TÜV SÜD's laboratory currently features a large and modern semi-anechoic RF chamber equipped with a pre-chamber for housing power amplifiers for radiated immunity tests, automated rotating table, and antenna positioning, measuring 15m x 6m x 5.5m. This chamber also includes integrated passive rollers on the floor to facilitate automotive testing on whole vehicles.

The installation of the three new chambers began in early June and is expected to be completed in approximately six weeks. These separate chambers will primarily focus on increasing the capacity for EMC testing on automotive components and implementing TÜV Italia's vision following the development of the first semi-anechoic chamber for vehicle, systems, and component testing. Frankonia, a market leader in this sector and already present in other TÜV SÜD locations, is the manufacturer of the new chambers.

The first chamber is a semi-anechoic chamber designed for emissions and immunity testing up to 18 GHz on automotive components, with dimensions of 6.53 x 6.38 x H 3.93 m. It includes a compliant table connected to the chamber wall, as required by regulations and specifications. The anechoic material installed in the chamber is a unique Frankonia patent, classified as A2 fire-resistant, allowing safe testing on hybrid components.

The second chamber is a shielded room measuring 3.90 x 3.08 x H 3.18 m, which will increase the capacity for conducted immunity tests, such as the Bulk Current Injection (BCI) on automotive components.

Finally, the third chamber is a reverberation chamber with dimensions of 5.33 x 3.48 x H 3.00 m. This is a novelty in the automotive field, as some manufacturer specifications are beginning to mandate immunity tests in reverberation chambers for components. The software used for these tests will be Nexio's BAT-EMC, a market-leading software for accredited laboratories already present in all TÜV Italia locations. It will facilitate standardized reporting and conducting highly challenging reverberation tests.

All the new chambers are equipped with DC filters for testing in both low voltage and high voltage (up to 1000 Vdc), as well as AC filters for three-phase samples.

Pietro Vergani, Business Unit Manager of COM within TÜV Italia's Product Service division, confirms, "The recent investments confirm the intention to remain a testing, validation, and homologation partner for our customers, with a clear focus in the Automotive sector. The new chambers expand and strengthen the range of tests that can be carried out within the Volpiano laboratory, ensuring compliance with the latest standards required by the market and covering the possibility of testing in various configurations and the latest technical solutions proposed by the Italian and international automotive industry. This significant investment complements the expansion plan of testing services, which, in recent years, has seen the implementation, in support of our technicians' expertise within a single laboratory located on the outskirts of Turin, of shakers and climatic chambers for environmental tests, including combined tests, a set of instrumentation for tests on High Voltage (HV) units, and equipment for EMC testing aligned with the most recent Automotive supply specifications."

In addition to the chambers, TÜV Italia has also invested in additional equipment for emissions and immunity testing, positioning itself to double its commitment to customers and provide new services and availability starting from the autumn. This further strengthens their already significant presence in the field of automotive testing (both LV and HV) as well as in civil and industrial sectors.
