asphaltInstallation and commissioning procedures for flash point and ignition point measuring instruments:

1. Before using this instrument, carefully read the user manual.

2. According to the test object, carefully read GB/T3536 "Determination of Flash Point and Ignition Point of Petroleum Products" to understand and familiarize yourself with the test methods, steps, and requirements outlined in the standard.

3. According to the requirements specified in the standard, the instrument should be placed in a dark and sheltered place for observing flash fires, and various testing instruments, materials, etc. should be prepared for the experiment.
