The penetrant testing of standard parts especially for the automotive industry requires some additional considerations regarding process reliability, process costs and waste management. The process usually comprises a fluorescent penetrant, water as the penetrant remover and some further defined developer. During the testing of serial parts quite significant amounts of waste water are generated out of the penetrant removing step while the penetrant concentration in the water rises constantly. In order to run a reliable testing process the water quality has to be closely monitored, otherwise the background fluorescence intensity rises. The use of a hydrocarbon free type of penetrant has a lot of advantages for the testing of standard parts compared to the usual hydrocarbon based material because the disposal of the water-penetrant mixture can be done through the sewage system without any further pretreatment. The process costs are reduced dramatically while using these new penetrants as proven by standard practical examples. The process reliability increases as well because the penetrant-water concentration is kept low. The new type of penetrants is comparable with the classic penetrants, containing hydrocarbons, in the point of process and sensitivity.
