 The corrected mean value of both measured flashpoints to standard pressureis119.54°C. The resulting average corrected flash point rounded down to the nearest multiple of 0.5°C is 119.5°C.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item has been determined to be 119.5 °C at 101.325 kPa.
Executive summary:

The flash point was determined using EU Method A.9 and DIN EN ISO 2719: Determination of Flash Point - Pensky Martens method. The test item was transferred to the sample cup of the Pensky-Mertens closed cup tester and replicate measurements of flashpoint were made corrected to 101.325 kPa atmospheric pressure. The flash point of the test substance has been determined to be 119.5 °C at 101.325 kPa.

1) FP observed : 122 °C at 995 hPa (P atmospheric)

FP corrected = FP observed + 0.23*(101.3 kPa – P atmospheric kPa)

2) FP corrected : 122 °C at 1013 hPa

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item has been determined to be 122 ± 2 °C ; Determination corrected to 101.325 kPa (conducted at 995 hPa).
Executive summary:

The flash point was determined using EU Method A.9: closed cup equilibrium method. An aliquot of the test item was transferred to the sample cup of the Setaflash tester. Atmospheric pressure was 995 hPa. Measurements were corrected to 101.325 kPa pressure. The flash point of the test substance has been determined to be 122 ± 2 °C at 101.325 kPa.

Description of key information

Weight of evidence: Flash-Point > 93 °C at 101.3 kPa, 2017

FP (Pensky-Mertens Closed Cup): 119.5 °C at 101.325 kPa atmospheric pressure, EU Method A.9, 2014

FP (Rapid Equilibrium Closed Cup): 122 ± 2 °C at 101.325 kPa atmospheric pressure, EU Method A.9, 2014

Key value for chemical safety assessment

Flash point at 101 325 Pa:
119.5 °C

Additional information

The flash point was determined using EU Method A.9 and DIN EN ISO 2719: Determination of Flash Point - Pensky Martens method. The flash point of the test substance has been determined to be 119.5 °C at 101.325 kPa.

 

The flash point was determined using EU Method A.9 closed cup equilibrium method. The flash point of the test substance has been determined to be 122 ± 2 °C at 101.325 kPa.

 

The weight of evidence for the substance indicates that the Flash-Point > 93 °C at 101.3 kPa.
