Any other information on results incl. tables

 Preliminary test

The test cup was filled with approximately 70 ml test substance, placed in the sample block of the flash-point tester, cooled overnight in a freezer at≤-75°C and then placed in the system for the determination of the flash point. The lid with a thermocouple for the determination of the flash-point and a resistance thermometer for measuring the temperature was placed on the cup. The test cup was heated with a rate of approximately 5°C/minute. The sample was stirred during heating. The flame igniter was applied so that it was lowered into the vapour space of the cup in 0.5 seconds, left in its lowered position for 1 second, and quickly raised to its high position again. The sample was not stirred when the igniter was applied.

 

The temperature of the test substance at the start of the test was 0°C. Starting at 2°C, an attempt was made to ignite the vapour of the test substance every 2°C temperature rise.

 

The atmospheric pressure was 1011.5 hPa.

 

 Main study

The test substance flashed at the first attempt in the preliminary test. According to this, the main study was not performed.

Applicant's summary and conclusion

Conclusions:

The Pensky-Martens closed cup method was not suitable for the determination of the flash-point of the reaction mass containing mainly 2-chloropropene.

The flash-point of the test substance is ≤ 2.5°C.
