Reference

Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

13 Jul 1999

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: The study was conducted according to an/the appropriate OECD test guideline, and in compliance with GLP.

Qualifier:

according to guideline

Guideline:

EU Method A.9 (Flash-Point)

GLP compliance:

yes

Type of method:

closed cup

Remarks:

Pensky-Martens (DIN EN 22719)

Flash point:

117 °C

Atm. press.:

100.9 kPa

Details:

Preliminary test

 

Flash-point: 113°C

 

Main study

Table 1: Flash-points determined during the main study:

Test number	Flash-point (°C)	Lowest Flash-point (°C)
1	117	117
2	117

 

The atmospheric pressure on the day of the test was 100.9 kPa

 

The lowest flash-point was corrected for the atmospheric pressure.

 

Corrected flash-point = 117 + 0.25(101.3 – 100.9)°C

                        = 117.1°C

           

 

Conclusions:

A flash point of 117°C at 100.9 kPa was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.

Description of key information

117°C at 100.9 kPa

Additional information

A flash point value of 117°C was determined for the substance using a relevant test method. The result is considered reliable. At temperatures > 150°C the evaporation of volatile components was observed and the substance decomposes at temperatures > 270°C.

The flash point of 117°C, with a boiling point at temperatures > 150°C, indicates that the substance should not be classified as a flammable liquid according to the criteria of Regulation 1272/2008/EC.
