12.1 Observe and record the ambient barometric pressure (see Note 20) at the time of the test. When the pressure differs from 101.3 kPa (760 mm Hg), correct the flash point or fire point, or both, as follows:
NOTE 20 - The barometric pressure used in this calculation is the ambient pressure for the laboratory at the time of test. Many aneroid barometers, such as those used at weather stations and airports, are precorrected to give sea level readings and would not give the correct reading for this test.
12.2 Using the corrected flash point or fire point, or both, as determined in 12.1, round the values to the nearest 1°C (2°F) and record.
13. Report
13.1 Report the corrected flash point or fire point value, or both, as the Test Method D92 Cleveland open cup flash point or fire point, or both, of the test specimen.
