15、s on testing7.1Processing qualityAt least 3 whole finished parts are aged in a stress-relieving medium e.g., 35% ZnCI2 solution (sol- dering fluid) for 48 h at room temperature. After being aged in the medium, the specimens must be rinsed with tap water and then dried for 24 h at 70 C. They are then evaluated.7.2Moisture contentThe moisture content is determined by drying the specimens in the (vacuum) oven. At least 3 specimens rrust be taken from 3 parts; these specimens are weighed with an accuracy of 0,01 g and
