Automatic Smoke Point Apparatus
Product Code : EL-FTLE-10893
Quick Answer: The Automatic Smoke Point Apparatus measures the smoke point of kerosenes and aviation turbine fuels per ASTM D1322 and IP 598, replacing the subjective, skill-dependent manual visual-rating method with a fully automated process. It automatically lights the prepared candle, applies a five-minute stabilization period, takes three flame-height determinations at 0.1 mm resolution, and reports the corrected mean smoke point, storing up to 100,000 results with USB, Ethernet/LAN, and printer output. Its repeatability and reproducibility (r=0.6, R=0.9) are about four times better than the manual test method (r=2.8, R=3.8).
The Smoke Point method, in accordance with ASTM D1322 and IP 598, is one of the oldest test methods in the petroleum industry. This test method provides an indication of the relative smoke-producing properties of kerosenes and aviation turbine fuels in a diffusion flame; the smoke point is related to the hydrocarbon composition of such fuels, and generally, the more aromatic the fuel, the smokier the flame, so a high smoke point indicates a fuel of low smoke-producing tendency. Performing the smoke point test manually requires highly skilled technicians with years of experience and is time consuming, and the visual rating method used for specification purposes suffers from operator subjectivity: the visual measurement of an open flame is a challenging exercise and dangerous for lab personnel, and the visual rating of the flame varies from one operator to another.
The smoke point test with the Automatic Smoke Point Apparatus is as simple as a flash point test with an automated instrument. The operator prepares the candle according to the test method instructions (phase 1), positions the candle on a conveyor (phase 2), and keys in all sample details before initiating the test (phase 3); the rest of the procedure is then fully automated. The candle is automatically lit, a five minutes stabilization time is followed by three determinations of the flame height, and at the end of the test the Automatic Smoke Point Apparatus calculates the mean value of the three flame heights measured. The result is rounded, then corrected with the memorized lamp correction factor (which is automatically calculated and used for result reporting), and finally reported according to the format specified in the test method. The result is saved in a built-in database, and it can be printed, transferred on a USB memory stick, and/or sent to a LIMS when the Automatic Smoke Point Apparatus is connected to a LAN.
