A 5ml sample is introduced into a vessel which is then charged with oxygen to 500kPa at a temperature of 15 to 25℃. The test is initiated by starting the heater and heating the pressure vessel to a temperature of 140℃. The pressure is recorded continuously until the breakpoint is reached. Alternatively, the test maybe terminated when a predetermined minimum requirement is reached.
KN-7525 Rapid Small Scale Oxidation Stability Tester
Overview
KN-7525 Rapid Small Scale Oxidation Stability Tester conforms to ASTM D7525 Standard Test Method for Oxidation Stability of Spark Ignition Fuel—Rapid Small Scale Oxidation Test (RSSOT) and ASTM D7545 Standard Test Method for Oxidation Stability of Middle Distillate Fuels—Rapid Small Scale Oxidation Test (RSSOT).
Features
Including an oxidation pressure vessel, which is equipped with a test sample cup that can be heated quickly, and equipped with a pressure sensor that can measure pressure up to 2000kPa and a temperature sensor withresolutionof0.1°C.
The integrated cooling fan cools the pressure vessel from the test temperature to the ambient temperature through air flow.
Temperature calibration device, including a cover and a temperature sensor, a thermometer with an accuracy of ±0.1°C.
2000kPa pressure sensor, calibrated to 10kpa
The extremely thin stainless steel pipe makes the dead volume small. With the help of high-temperature and high-pressure solenoid valve, the flow-limiting proportional valve realizes the oxygen filling and deoxygenation actions at the specified flow rate. During the test, the pressure and temperature in the oxidation vessel are continuously recorded. Calculate the oxidation time and judge the oxidation end point.
Adopt safety protection insulation heat shield, high pressure relief valve, automatic pressure relief device to protect the personal safety.
The independent instrument (without external PC) adopts a modernly designed 5.7" touch screen. During the test, the pressure curve can be monitored on the screen, and temperature, time and pressure valuecan be displayed in real time.
