Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
flash point of flammable liquids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
19-21 Feb 2001
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: GLP guideline study with the substance in a liquid state, purity 353 g/kg.
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
GLP compliance:
yes
Type of method:
closed cup
Remarks:
Pensky-Martens flash point tester (ATPEM) built in accordance with ASTM D93, NF EN 22719, ISO 2719 and DIN 51758 standards
Flash point:
> 100 °C
Atm. press.:
1 006 hPa
Remarks on result:
other: No flash point was detected between ambient temperature and 100°C.

Description of key information

not applicable for solid substance

in aqueous solution (353 g/kg) : > 100 °C at 1006 hPa

Key value for chemical safety assessment

Additional information

Flash point does need to be determined, because the substance is a solid, and the melting point is high (> 250 °C). For an aqueous solution (concentration 353 g/kg) no flash point up to 100 °C could be determined in the Pensky-Martens closed cup experiment, according to EU Method A.9.
