Flammable solid test

Flammable solid test
1. Test method
Closed cup method: Place the solid sample in a closed cup, gradually increase the temperature and introduce an ignition source, and observe the temperature at which the sample is ignited. This method is simple to operate and can simulate the combustion of solids in a closed environment, but volatile solids may affect the results due to pressure changes.
Open cup method: Place the sample in an open cup, increase the temperature and introduce an ignition source, which can more realistically reflect the combustion characteristics of solids in an open environment, but it is easily affected by external airflow.
Cleveland open cup method: Improved on the basis of the open cup method, the ignition source control and temperature measurement are more accurate, but the operation is complicated and requires higher equipment and personnel.
2. Influencing factors
Sample purity: Impurities may change the combustion characteristics and cause deviations in flash point determination.
Heating rate: Too fast may lead to higher measured values, and too slow may extend the measurement time.
Environmental factors: Ventilation conditions, humidity and air pressure may affect the measurement results.
3. Test precautions
Ensure that the experimental equipment is intact and conduct the test in strict accordance with the operating procedures.
Operators should wear appropriate protective equipment, assess potential hazards and develop emergency plans.
