Technical Parameters

Product Description

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.

Scope of 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

Test Procedures

Sample Preparation: Pour liquid sample into the test chamber according to standard volume requirements.

System Setup: Install sensors, ignition source, and ensure chamber sealing.

Testing: Gradually heat the liquid under controlled conditions until autoignition occurs.

Data Recording: Capture the autoignition temperature and any associated observations for analysis.

Maintenance Information

Daily Cleaning: Clean the chamber, sensors, and ignition source after each test to prevent residue buildup.

Calibration: Regularly calibrate temperature sensors and ignition system to maintain accuracy.

Inspection: Check electrical connections, seals, and chamber integrity for wear or damage.

Storage: Keep in a dry, ventilated area and avoid exposure to flammable residues.
