no

Qualifier:

according to guideline

Guideline:

ASTM D93 (Standard test methods for flash point by pensky-martens closed cup tester)

Deviations:

no

GLP compliance:

yes

Remarks:

Key result

Flash point:

>= 158 - <= 160 °C

Atm. press.:

>= 100.2 - <= 101.8 kPa

Reference Substance: The average (n = 2) observed flash-point of the Reference Substance n-hexadecane was 133 ± 1 °C, which was not significantly different from the reported (ASTM 93-85) value of 133 ± 6 °C, indicating acceptable method accuracy.

Test Substance: The average (n = 2) observed flash-point of the test material was 159 ± 1 °C at 100.2 kPa to 101.8 kPa (751.6 to 763.6 mm Hg). At temperatures below 159 °C, the instrument stirrer malfunctioned due to the solidification of the test material. Therefore, the test could not be conducted below 159 °C. It should be noted that flammable vapours may be emitted from the test material at temperatures below 159 °C.

Interpretation of results:

study cannot be used for classification

Conclusions:

Under the conditions of this study the observed flash point of the test material was 159 ± 1 °C at 100.2 kPa to 101.8 kPa.

Executive summary:

The flash point of the test material was investigated in accordance with the standardised guidelines EU Method A.9 and ASTM 93-85, under GLP conditions, using the closed cup method. 

Molten test material (~ 75 mL) was added to the test cup. An ignition source was directed into the test cup at 2 °C intervals as the sample cooled (with simultaneous interruption of stirring as above), until a flash was no longer detected or the test could not be continued because of stirrer malfunction due to solidification of the test material.

Under the conditions of this study the observed flash point of the test material was 159 ± 1 °C at 100.2 kPa to 101.8 kPa.

Description of key information

Under the conditions of this study the observed flash point of the test material was 159 ± 1 °C at 100.2 kPa to 101.8 kPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

159 °C

Additional information

The flash point of the test material was investigated in accordance with the standardised guidelines OJEC method A9 (OJEC, 1992) and ASTM 93-85, under GLP conditions, using the closed cup method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

Molten test material (~ 75 mL) was added to the test cup. An ignition source was directed into the test cup at 2 °C intervals as the sample cooled (with simultaneous interruption of stirring as above), until a flash was no longer detected or the test could not be continued because of stirrer malfunction due to solidification of the test material.

Under the conditions of this study the observed flash point of the test material was 159 ± 1 °C at 100.2 kPa to 101.8 kPa.
