Compliance Standard : ASTM D1322 – Standard Test Method for Smoke Point of Kerosene & Aviation Turbine Fuel (latest ASTM D1322-25), Many units also meet equivalent standards such as ISO 3014, IP 57, DIN 51406, FTM 791-2107, and NF M 07-028 in fuel testing applications.
Application : The smoke point apparatus is used to determine the smoke point of kerosene, aviation turbine fuels and similar petroleum distillates — that is, the maximum flame height at which a fuel burns without producing visible smoke under controlled conditions. This measurement provides an indication of the fuel’s combustion quality and smoke-producing tendencies, which relates to aromatic content and thermal characteristics important in aviation and fuel quality control.
Product Description : The Smoke Point Apparatus generally consists of a wick-fed lamp burner, fuel reservoir, adjustable wick tube mechanism, and a graduated scale against which the flame height is read. During the test, the fuel sample is burned; the wick is adjusted to locate the highest smokeless flame height, defined as the smoke point (typically reported in millimetres). Â Typical construction includes durable materials like borosilicate glass for reservoirs and chimneys, brass or stainless components, and a stable bench-top base for safety and repeatability.
