- Lot/batch No(s): N3447
- Storage condition of test material: room temperature

Key result

Remarks on result:

no flash point up to 100°C

In test substance determination, no flash was seen up to 110 °C. In the reference substance determination, no flash was observed up to 81 °C, but a positive flash was seen at 82 °C. The atmispheric pressure at the time of measurement was 750.1 mm Hg (100.01 kPa). Correction was applied to the reference result to give the flash temperature at standard atmospheric pressure, 82.3 °C at 101.325 kPa, which is considered acceptable.

The followinf formula for correction was used:

Corrected value = Observed value + ((101.325 - Atmospheric pressure [kPa]) / 4)

Interpretation of results:

GHS criteria not met

Conclusions:

The flash point of MCPP-P 2-EHE was determined by a closed cup equilibrium method. No flash point was observed up to 110 °C, when tested at 100.0 kPa atmospheric pressure.

Executive summary:

A study was conducted according to Regulation (EC) No 92/69/EEC method A.9, ISO 3679:1983 and ASTM D3278 to determine flash point of the test item using a closed cup equilibrium method. Nominally 2 ml of the test item were filled in the measurement cup, equilibrated for one minute at the initial temperature and then heated with a flame. Observations for evidence of a flash were made. The test substance was heated to the maximum apparatus temperature 110 °C. No flash point at atmospheric pressure (100.01 kPa) was observed up to this temperature. A reference substance - n-octanol, was measured at the same conditions and a flash point of 82.3 °C (after correction at standard atmospheric pressure) was determined. The result was considered acceptable (literature flash point of n-octanol: 81 ± 2 °C). Therefore, MCPP-P 2-EHE has no flash point up to 110 °C.

Description of key information

No flash point was observed up to 110 °C.

Additional information

A study was conducted according to Regulation (EC) No 92/69/EEC method A.9, ISO 3679:1983 and ASTM D3278 to determine flash point of the test item using a closed cup equilibrium method [MCPP-P Task Force, 1999]. Nominally 2 ml of the test item were filled in the measurement cup, equilibrated for one minute at the initial temperature and then heated with a flame. Observations for evidence of a flash were made. The test substance was heated to the maximum apparatus temperature 110 °C. No flash point at atmospheric pressure (100.01 kPa) was observed up to this temperature. A reference substance - n-octanol, was measured at the same conditions and a flash point of 82.3 °C (after correction at standard atmospheric pressure) was determined. The result was considered acceptable (literature flash point of n-octanol: 81 ± 2 °C). Therefore, MCPP-P 2-EHE has no flash point up to 110°C.
