Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Study in accordance with Method A9 of Commission Directive 92/69/EEC (Annex V). Purity and isomers composition specified.
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Version / remarks:
92/69/EEC
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
1983
Qualifier:
according to guideline
Guideline:
ASTM D3278 (Standard test methods for flash point of liquids by small scale closed-cup apparatus)
Version / remarks:
1996
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
Swiss GLP compliance programme (inspected on September 09 and 30, 2002/ signed on December 2002)
Type of method:
closed cup
Flash point apparatus:
other: Rapid Flash Tester RT-1
Dynamic viscosity of test material:
Viscosity of the test material is not specified, but the substance is described as slightly viscous (please refer to endpoint 4.1), therefore the method is assumed to be suitable.
Specific details on test material used for the study:
- Physical state: liquid
- Storage condition of test material: refrigerator (0-10°C) under nitrogen
Key result
Flash point:
ca. 181 °C
Atm. press.:
101.325 kPa
Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
The substance is NOT classified as flammable liquid according to CLP and GHS criteria (FP>93°C).
Executive summary:

The flash point of the test substance was determined under GLP according to ISO 3679 (listed in EU A.9 guideline), using a closed cup equilibrium method.

The flash point of the test material was of 181 +/- 2 °C

Description of key information

The substance is NOT classified as flammable liquid according to CLP or UN GHS criteria.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
181 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EU/ISO guideline (equilibrium closed cup method) and under GLP, is available. It is considered as a key study, and the result is retained as key data.

This study is relevant for the classification regarding flammable properties. (see IU Section 4.13 endpoint summary for justification of non-classification)
