About AC Contrôle
AC Contrôle Sàrl is an independent material testing laboratory located in Bex in the Canton of Waadt. The company performs non-destructive testing (NDT) on welds, components, and equipment – using X-ray radiography and gamma radiation with Iridium 192, ultrasonic testing, magnetic particle testing, liquid penetrant testing, and visual inspection, both directly on-site or at the construction site. Furthermore, the company offers destructive and mechanical testing, including tensile tests up to 120 kN (up to 1000 kN in cooperation), bend tests, hardness measurements (Vickers, Rockwell C, Brinell, microhardness), Charpy impact tests between -196 °C and +100 °C, as well as macro- and microphotography. The offering is supplemented by pressure testing on equipment, dimensional checks, damage analysis (crack, corrosion, and failure causes), as well as consultation and certification of welders and brazing specialists. The laboratory is accredited by the Swiss Safety Center for mechanical, technological, metallurgical, and non-destructive testing of pressurized equipment and recognized as a person certification body according to ISO/IEC 17024 (SECO, SCESe 0119). Customers come from the fields of pressurized vessels and piping, welding and steel construction, mechanical engineering, and cable car industry.
