experimental study
Adequacy of study:
key study
Study period:
from 1992-03-30 to 1992-09-24
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Version / remarks:
Directive 67/548/EEC
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO No., other: DIN 51758
Deviations:
no
Principles of method if other than guideline:
Guideline DIN 51758 was used
GLP compliance:
yes
Type of method:
other: not specified
Key result
Flash point:
70 °C
Atm. press.:
>= 1 006 - <= 1 020 hPa
Remarks on result:
other: lowest value

During the study the atmospheric pressure was in the range 1006 -1020 hPa. In accordance with DIN 51758 the study was performed using a fully automatic apparatus (PMA 2, Coesfeld). The ignitions trials were examined automatically. At the sample temperature of 102 °C an ignition was oberved. Further tests were performed according DIN 51758 in semiautomatic and, respectively, fully automated apparatus (PMP1 / PM1, Coesfeld). As ignition source a coiled filament (PMP1 apparatus) or an igniting flame (PM1 apparatus) were used. Ignitions were only detected visually by the study director. Ignitions (flash points) were observed at the following temperatures: 92 °C, 87 °C, 70 °C and 74 °C. Due to the dispersive measuring values and the test item's peroperties further investigations were carried out with a new sample of the test item according to guideline DIN 53213 part 1. In these measurements ignitions were observed at 85 °C and 83 °C (outside the guideline's scope). Because of the differences in atmospheric pressures during the test no corrections to normal pressure were done. The lowest flash point was 70 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item was determined to be 70 °C (at 1006 - 1020 hPa).
Executive summary:

The flash point of the test item was assessed according to EU method A.9. The flash point was determined to be 70 °C (at 1006 - 1020 hPa). This was the lowest value determined. Because of the differences in atmospheric pressures during the test no corrections to normal pressure were done.

Description of key information

The flash point of the test item was determined to be 70 °C (at 1006 - 1020 hPa).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
70 °C

Additional information

The flash point of the test item was assessed according to EU method A.9. The flash point was determined to be 70 °C (at 1006 - 1020 hPa). This was the lowest value determined. Because of the differences in atmospheric pressures during the test no corrections to normal pressure were done.
