Flammability tests for hemp seed oil

The objective of this study was to determine the lowest temperature at which hemp seed oil ignited (505°C) and also the highest temperature at which hemp seed oil did not ignite in at least three tests performed (500°C). The oil was tested on a cylindrical surface heated to various temperatures. A total of 16 tests were carried out to determine these two temperatures as accurately as possible. The tests were performed under the procedure complying with ISO 20823:2018, Petroleum and related products. Determination of the flammability characteristics of fluids in contact with hot surfaces. Manifold ignition test.
