Initial boiling point (BP) is the lowest temperature at which a liquid begins to boil. Most liquid products are complex mixtures containing components with different boiling points, and without proper testing it is impossible to accurately predict their BP. In safety and regulatory work, the BP is often used together with the Flash Point to determine the flammability classification of liquids.
At LCS Laboratory, we measure the Initial Boiling Point of both pure substances and complex mixtures, delivering reliable results even for challenging samples. We follow the OECD 103 test method. During the test, the sample is gradually heated and three key temperatures are recorded:
-
Pre-boiling temperature – when consistent bubbling first appears
-
Steady boiling temperature – when continuous, stable boiling is observed
-
End-of-boiling temperature – when the heat source is removed and boiling ceases
In most cases, these three measurements fall within a 1 °C range, ensuring reproducible and dependable results.
