KEY: good or positive icon advantage, bad disadvantage

blau icon Acoustic testing

good, positive, vorteil icon Checks the sum of all the properties of the test object
good, positive, vorteil icon Quick and cheap testing method (real-time)
good, positive, vorteil icon Compact testing without any additional equipment, directly good / bad statement
good, positive, vorteil icon Flexible installation, easy configuration
good, positive, vorteil icon Utilisation even in rough industrial environments (IP67)

dunkelblau icon Magnetic particle inspection

good, positive, vorteil icon Magnetically conductive components
bad, negative, nachteil icon Fault detection can be changed by false indications                                                      (magnetic stray fields of surface structures are only partially documentable)
bad, negative, nachteil icon Multistage, heavy automatable method of cleaning supplies and material                      consumption

pink icon X-ray CT

good, positive, vorteil icon Internal, inaccessible complex geometries
bad, negative, nachteil icon For fissures only specifically applicable (fault location must be known)
bad, negative, nachteil icon Equipment-and time-consuming process
bad, negative, nachteil icon Radiation hazards and high training costs

gelb icon Optical systems

good, positive, vorteil icon External or easily accessible internal surface
bad, negative, nachteil icon Susceptible to dirt and humidity
bad, negative, nachteil icon Reduced measuring accuracy at shiny surfaces or changing light conditions
bad, negative, nachteil icon Reduced cycle times / additional equipment needed

orange icon Eddy current

good, positive, vorteil icon Rotationally symmetrical inner and outer surfaces (usually rod material)
good, positive, vorteil icon Flat surfaces
bad, negative, nachteil icon Low depth of penetration + low range
bad, negative, nachteil icon Several test channels for different types of faults and orientations of fissures
