Flash point

Link to relevant study record(s)

Reference

Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From 08 April 2010 to 21 May 2010

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: compliant to GLP and testing guideline; adequate coherence between data, comments and conclusions

Qualifier:

according to guideline

Guideline:

EU Method A.9 (Flash-Point)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Type of method:

closed cup

Flash point:

-8 °C

Atm. press.:

98.2 kPa

Preliminary test:

Atmospheric pressure: About 98.3 kPa

Relative humidity: About 41% of saturated air

Tested temperature range: Between - 9.3 and 30.0 °C (corrected values)

The flash point was observed between - 9.3 and - 3.8 °C (corrected values).

Remark: During this preliminary test, as the temperature tested was much higher than the flash point temperature obtained, a continuous, growing flame was observed and by inadvertence was not considered as a flash point. Then, the test item was cooled and the flash point find between - 9.3 and - 3.8 °C.

Conclusions:

The flash point of the test item was: - 8.0 ± 0.5 °C (corrected value).

Key value for chemical safety assessment
