A network of accredited laboratories, offering a diversified range of services aimed at industry, health, commerce and services, public entities and individuals, who need to ensure that their facilities, equipment and products comply with Quality and safety requirements.

Wide range of tests and analysis

ISQ accredited Laboratories do not only support the in-house Engineering, Inspection and Training divisions but also provide external services for instance to the Manufacturing sector, Oil & Gas, Aeronautical & Aerospace, Healthcare, Pharmaceutics, Medical Cannabis, Agrifood, Research Infrastructure, Public Administration, Civil Construction, Energy Generation, Automotive Industry and Transport Infrastructure including Railway.

ISQ Testing offer covers the domains of Materials and Mechanics, Thermodynamics, Noise and Vibration, Environment and Chemistry, Energy, Metrology and Product (including reliability).

The accumulated experience and know-how is combined with the continuous development of new methodologies and processes allowing ISQ to be, today, a leading partner for some global organisations in the design, development, construction and implementation of their own testing or research laboratories.

ISQ track record includes also the design, construction and operation of specialised test benches for very special application in the Aeronautical & Aerospace sectors or the development of particular testing methodologies to be used in experimental nuclear facilities.
