An electrometric method for determination of nitric acid in RDX(B) liquors has been developed. The method is not largely affected by ammonium nitrate and acetic anhydride. A precision of ± 0.5% may be readily obtained. Acetic anhydride in RDX(B) liquors may be determined by direct titration with standard aniline–toluene solution at 0 °C., using calcium hypochlorite as an external indicator. In routine analysis, a precision of ± 2% may be obtained.

Point To Point

In avionics equipment maintenance, electronic equipment failure or mal function caused by PCB that happens frequently. Due to the complexity of large circuit network cross linking, it is hard to solve such a troubleshooting by point to point. Advanced avionics, such as GNS430, VHF155A, G1000 integrated avionics system are using SMT technology. Because of PCB’s greatly fine line and the ultra-fine pitch components, it is highly difficult for electronic equipment test. Video optical detection technology for PCB detection technology is developed rapidly in recent years. It gradually began to replace the original visual detection and electrometric method, and it has a high fault resolution.
