Based upon laboratory test results, the West German representative to the UN Committee on the Transportation of Dangerous Goods has recommended that Ammonium Perchlorate AP of all particle sizes be classified as a Class 1.1 explosive. If this recommendation is adopted it will have a drastic effect on the transportation of ammonium perchlorate with commercial concerns and military agencies. Under current regulations, only AP with a particle size less than 45 microns is considered Class 1.1 the latest DARCOM regulation specifies 15 microns or less. Above 45 microns, AP is classified as a 5.1 oxidizer. In order to resolve this difference, a plan for conducting UN Test Series 6 for packaged AP, 200 micron size in 30 gallon, 250 lb steel drums was developed in cooperation with the JANNAF Interagency Propulsion Committee and DARCOM Safety Office. This paper discusses the test plan, testing, results and recommendations. Author
