Flammability

Administrative data

Endpoint:

flammable solids

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

Cross-reference

Cross-reference 1

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: from the Quality Certificate of the substance

Qualifier:

no guideline followed

GLP compliance:

no

Physical state at 20°C and 1013 hPa:

liquid

Cross-reference 2

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

flash point of flammable liquids

Type of information:

experimental study

Adequacy of study:

key study

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:

2012

Deviations:

no

Qualifier:

according to guideline

Guideline:

ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)

Version / remarks:

2002

Deviations:

yes

Remarks:

see field below

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.9 (Flash-Point)

Version / remarks:

2008

Principles of method if other than guideline:

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.
