Liquid Autoignition Point Tester
Category：Flammability Tester
Introduction
The Liquid Autoignition Point Tester is a device used to determine the lowest temperature at which a liquid spontaneously ignites without an external ignition source. This tester is used to determine the autoignition temperature of liquid chemicals in a uniformly heated container under atmospheric pressure, including both hot-flame and cold-flame ignition conditions.
Application and Standards
The Liquid Autoignition Point Tester is used to determine the hot-flame and cold-flame autoignition temperatures of liquid chemicals under atmospheric pressure.
Complies with:
GB/T 21860-2008: Test Method for Autoignition Temperature of Liquid Chemicals
ASTM E659-78 (2005): Standard Test Method for Autoignition Temperature of Liquids
