ASTM D 1322, D 1655
DEF STAN 91/91
The Smoke Point method, in accordance with ASTM D1322, IP 598, is one of the oldest test methods in the petroleum industry. It is one of the last manual methods that has never been automated before. Performing the smoke point test manually requires highly skilled technicians with years of experience. Additionally, the manual test is time consuming. The current visual rating method used for specification purposes suffers from the drawback of operator subjectivity. The visual measurement of an open flame is a challenging exercise and dangerous for lab personnel. The visual rating of the flame varies from one operator to another.
The SP10 Revolutionizes Smoke Point Testing
It uses a system that adjusts the size of the flame associated to a video camera that observes the flame. When the flame attains the shape described in the test method, the SP 10 memorizes and reports the height of the flame. Every test is fully documented and traceable which is important for aviation industry quality procedures.
The SP10 has been made the referee method in D1322:
§6.2.2 of ASTM D1322: “Due to the vastly superior resolution of the digital camera compared to the human eye, smoke point shall be measured by the automated unit when available. In case of dispute between results from manual and automated methods, the referee shall be considered the automated method.”
