EXPLANATION
This test method is applicable to petroleum fractions that can be burned completely without smoking in a wick lamp.
TEST SUMMARY
A sample is burned from a cotton wick in an atmosphere of purified air. The water formed is collected from the combustion gases by a desiccant and weighed.
TEST PRECISION
In the hydrogen content range of 11 to 16 mass %, this test method has a repeatability of 0.11 and a reproducibility of 0.18.
The bias of this test method has not be determined.
