Ignition Point

Ignition Point refers to the lowest temperature at which a substance, when heated in air, can ignite spontaneously and continue to burn. In foreign trade, this term is mainly used in the transportation, storage, and customs declaration of chemicals, oils, dangerous goods, etc. Usage scenarios include: preparation of MSDS (Material Safety Data Sheet), dangerous goods sea/air transport declaration, commodity inspection, and quality clauses in contracts. Note: Ignition Point is different from Flash Point. Flash Point refers to the lowest temperature at which a liquid emits flammable vapor that, when mixed with air, can flash upon contact with an ignition source, while Ignition Point is the temperature for sustained combustion, usually higher than Flash Point. In addition, Ignition Point is also different from Autoignition Temperature, which refers to the temperature at which a substance self-heats and burns without an external ignition source. Foreign trade practitioners need to accurately distinguish these terms to avoid cargo detention, fines, or safety accidents due to declaration errors. When signing contracts, the test standard for Ignition Point (such as ASTM D93, ISO 2719, etc.) should be clearly specified and consistent with the buyer's requirements.
