		EVAPORATION RESIDUE TESTING HGT 915/917 Gum Test Apparatus Safe, simple quality control of aviation fuels & gasoline ASTM D 381, ISO 6246, EN 5, IP 131 The Herzog Gum Test Apparatus is designed to measure evaporation residue in aviation fuels, motor gasolines, and other volatile distillates in accordance with ASTM D 381, ISO 6246, EN 5 and IP 131 test methods. The HGT 915 uses air evaporation, while the HGT 917 offers the versatility Of either air or Steam evaporation. Both models are capable of testing three ioo ml samples simultaneously. Results indicate the likelihood of induction system deposits and potential sticking of intake valves. Block temperature is factory set for a temperature of approximately 162°C in air evaporation units and 232°C in steam evaporation units. The temperature of the evaporation air or steam is controlled by pressure regulation. Model 917 includes an integral Steam super heater as well as a built-in switch which permits changeover from air to steam evaporation when required.
