Thermodynamics

The Thermotechnics Laboratory conducts tests on the main components of systems and physical-mechanical equipment used to regulate temperature, humidity, and air exchange, optimizing indoor comfort and well-being.

The laboratory tests various equipment and devices, including radiators, fireplaces, biomass stoves and boilers, water and gas valves, pipes, fittings, manifolds, and air conditioning system components.

What are the ACCREDIA-accredited tests in this section?

Industrial Valves

We perform tests on various types of industrial valves, including:

• Ball valves
• Butterfly valves
• Wedge valves
• Check valves (non-return valves)
• Shut-off valves
• Diverter valves
• Globe valves
• Steel valves
• Disc valves
• Cast iron, brass, composite, and plastic valves

Tests performed on valves, filters, manifolds, fittings, and pipes include:

• Flow rate and pressure loss characteristics of water valves and determination of the KV coefficient according to IEC 60534-2-3:2015
• Verification of operating pressure/temperature range according to UNI 8858
• Valve testing according to UNI EN 331 and UNI EN 13828
• Pipe and fitting testing according to UNI EN ISO 21003, UNI TS 11344, and UNI EN 1254
• Operating force resistance tests
• Housing and seat strength tests, and determination of valve tightness class according to UNI EN 12266 and UNI EN 1074
• Compliance assessment with supply specifications and pre-shipment inspections
• Thermal shock resistance tests, endurance and durability tests
• Chemical resistance tests
