: Provides the specific test methods for assessing cleanliness, such as Ionic Contamination (IC) and Surface Insulation Resistance (SIR) testing. Why It Matters for Reliability
For life-safety applications, cleaning is mandatory after assembly. recommends a two-stage verification: first, visual inspection under magnification (typically 10-30x), second, ionic contamination testing using a dynamic ROSE tester with limits below 1.56 µg/cm² NaCl equivalents. ipc-ch-65
