ABSTRACT A PROCESS FOR DETERMINING THE API GRAVITY OF OIL The API gravity of an oil is determined by vaporizing its volatile and pyrolyzable components, measuring the ratio of the amount vaporized within a range of relatively high temperatures to the total amount vaporized and determining that the gravity of the oil being tested equals that of an oil which has a similar composition and which, when a substantially equal amount is tested under substantially the same conditions, yields a similar ratio of amounts vaporized at the same temperatures.
