Therefore acertain number of products or racks are rinsed in a defined rinsing tank, at the usualconditions, and the rinsing water is analysed afterwards.The actual rinsing criterium is determined from measurements in the plant to determine theoptimum solution of the adhering liquid film on the workpiece after the last rinsing step,from the suppliers of the chemistry of the following baths, or from literature.The programme routine ZEPRA was developed using MS Excel and Visual Basic. Thefollowing calculations are currently represented in ZEPRA: pickling degreasing anodizing evaporation drag out15
