Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2017-01-24
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
March 2015

Conclusion

The flash point of the test item was 13.0 ± 0.5°C (corrected value).

Interpretation of results:
Category 2 (highly flammable liquids) based on GHS criteria
Conclusions:
A flash point of 13.0 ± 0.5°C at 1013 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.

Description of key information

Flash point: 13.0 ± 0.5°C at 1013 hPa (ISO 3679)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
13 °C

Additional information

A measured flash point value of 13.0 ± 0.5°C at 1013 hPa was determined for the registration substance using a rapid equilibrium closed-cup method in accordance with ISO 3679 Test Method and in compliance with GLP. The result is considered to be reliable.

A measured flash point of 13.0 ± 0.5°C and measured boiling point of 96.2°C indicate that the registration substance should be classified as a flammable liquid (Category 2) in accordance with Regulation (EC) No. 1272/2008.
