Zusammenfassung:	The storage stability of jet fuels containing anti-icing additive P55MB was investigated during a storage period of 5 months. Tests included (1) thermal stability, (2) gum content, (3) API gravity, (4) aniline point, and (5) sulfide content. The effect of the additive on the extent of removal of corrosion products by flaking was investigated. Also investigated was the effect of the additive in promoting or limiting the growth of microorganisms found in the natural water bottoms of fuel storage tanks. The physical stability of solutions of additive P55MB in jet fuel was studied as well as the water-retention characteristics of P55MB in jet fuel. The effects of anti-icing additives P55MB and Additive A on the hardness of the topcoating of the fuel tanks were studied in detail. A graphical relationship is given between the laboratory method and the field method (Sward Rocker Hardness Test and Pencil Hardness Test, respectively) of determining the hardness of the fuel-tank topcoating.
