International audienceThe activelly cooled plasma facing units (PFUs) constituting the WEST lower divertor must meet stricttechnical specifications before their installation into the WEST tokamak. The tests performed at CEAlead mainly: to provide information on the feasibility to attach mechanically PFUs on sectors, toensure geometrical tolerances for the welding of PFUs to water manifolds, to check the PFU vacuumtightness and to confirm the PFUs heat exhaust capability. Using high heat flux (HHF) test facilities,such as HADES at CEA-Cadarache and GLADIS at IPP-Garching,∼5%of the PFU production wastested. Infrared thermography (IR) tests were also performed (∼24% of the PFU production tested).Weshow that PFUs are with a quality in agreement to the requirements and that the assessement of theheat exhaust capability during the series production is needed. Based on statistical approaches, thiswork also provides information on the methods to assess the quality of tested components usingstatistic process control
