TAM / PSM
Testing And Monitoring / Penetrant System Monitoring
TAM – Testing And Monitoring panels and PSM – Penetrant System Monitoring panels are test-pieces used to validate the sensitivity of dye penetrant inspections. These contain star-burst or linear-shaped defects of varying sizes on a chrome strip of fine surface finish. Signal to noise can be qualitatively determined by comparing the defect response to that of the noise from the surface roughness provided by grit-blasting.
It is important to check that the TAM panel complies with all of the relevant standards and codes and that the panel is well cleaned and maintained to ensure repeatable performance.
