Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
Justification for type of information:
a flash point study is available

Study period:
from 20 March 2018 to 24 April 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
according to guideline
Guideline:
other: ASTM D7094: “Standard Test Method for Flash Point by Modified Continuously Closed Cup (MCCCFP) Tester”
Version / remarks:

Guideline:
EU Method A.9 (Flash-Point)

remark of reviewer:
Several non-equilibrium methods are mentioned in the EC A.9 guideline. According to the study report the study was performed according to ISO Guide 2719 (Pensky-Martens closed cup). However, from the description of the test performance and the flash-point tester it was concluded that ASTM D7094 (modified continuously closed cup) is more applicable. ASTM D7094 is not mentioned in the EC A.9 guideline but is a commonly used and safer (low sample volume) alternative for the ISO 2719 method.
GLP compliance:
yes
Type of method:
non-equilibrium method closed cup
Flash point apparatus:
other: Eraflash (Eralytics, Austria)
Dynamic viscosity of test material:
no data
Specific details on test material used for the study:
Boiling temperature: 259°C
Key result
Flash point:
122 °C
Atm. press.:
1 013 hPa

Test 1: 122°C

Test 2: 124°C

As the difference between the results is ≤ 6°C, the lowest flash point value obtained was reported as the flash point of the substance.

Interpretation of results:
other: not classified under CLP or GHS
Conclusions:
The flash point of the substance was determined to be 122°C (at 1013 hPa).
Executive summary:

The flash point of the substance was determined using the modified continuously closed cup ASTM D7094 method (GLP study).

The flash point was determined in duplicate obtaining a lowest value of 122°C (at 1013 hPa).

ASTM D7094 is not mentioned in the EC A.9 flash point guideline but is a commonly used and safer (low sample volume) alternative for the ISO 2719 Pensky Martens closed method.
