3 Terms and Definitions
The following terms and definitions apply to this document:
3:1
sediment deposits
Oxidation products deposited on the heated tube test area and/or trapped on the test filter:
NOTE: Fuel deposits tend to be concentrated in the hottest part of the heating tube, i:e: between 30 mm and 50 mm:
3:2
heater tube
Aluminum sample tubes with controlled heating surfaces:
NOTE: The tube is heat-resistant and has a built-in thermocouple to control the temperature: The effective test area of the tube is located between the two shoulders of the tube, that is, the thinner part with a length of 60mm: try
The sample enters from 0mm and exits from 60mm:
3:3
breakpoint breakpoint
The sample meets the maximum temperature required by the heater tube wall rating and differential pressure (ΔP) specification across the filter:
4 Overview
This document uses jet fuel thermal oxidation stability tester to measure the high temperature oxidation stability of jet fuel, the test conditions can be set
Linked to actual operating conditions of jet turbine engine fuel systems: The sample is pumped through the heating tube at a fixed volume flow rate, and then enters the
