Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 27 November 2012 to 29 November 2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Substance ID is adequately specified with purity and isomers composition. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Qualifier:
according to guideline
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
International standard ISO 3679-2004 (E), second edition - 2004-04-01, p1-18
Qualifier:
according to guideline
Guideline:
ASTM D3278 (Standard test methods for flash point of liquids by small scale closed-cup apparatus)
Version / remarks:
ASTM D-3278-89, p1-7
Qualifier:
according to guideline
Guideline:
other: Anon (1983) Paints, varnishes, petroleum and related products - Determination of Flash Point - Rapid equilibrium method Anon (1989) Flash Point of liquids by Setaflash Closed-cup apparatus,
GLP compliance:
yes (incl. QA statement)
Remarks:
UK GLP Compliance Programme (inspected on 10 July 2012 / signed on 30 Nov. 2012)
Type of method:
equilibrium method closed cup
Flash point apparatus:
Setaflash apparatus
Dynamic viscosity of test material:
A kinematic viscosity of 8.37 mm2/s at 20°C was measured (please refer to IU section 4.22), corresponding to a dynamic viscosity of 7.8 mPa.s with the density of 0.936 (please refer to IU section 4.4).
Specific details on test material used for the study:
- Storage condition of test material: room temperature, in the dark.
Key result
Flash point:
104 °C
Atm. press.:
101 325 Pa

Temperature (°C) Observations
21°C to 101°C,
5°C increments
No flash.
106°C A blue flash spread across the sample cup.
101°C (fresh sample) No flash.
102°C  No flash.
103°C  A blue flash spread across the sample cup. 
103°C (fresh sample)  No flash. 
104°C (fresh sample)  A blue flash spread across the sample cup. 
104°C (fresh sample)  A blue flash spread across the sample cup.
102°C (fresh sample)  No flash.
102°C (fresh sample)  No flash.

Observed flash point = 104°C

Atmospheric pressure = 101.1 kPa

Corrected flash point = 104.05°C

Interpretation of results:
GHS criteria not met
Remarks:
GHS and EU-CLP criteria not met
Conclusions:
The flash point of test substance is above the classification thresholds of 60°C (CLP criteria) or 93°C (GHS criteria). Therefore, test substance is not a flammable liquid according to CLP and GHS criteria.
Executive summary:

The flash point of the test substance was measured according to ISO 3679 (listed in EU A9 guideline), closed cup equilibrium method, under GLP.

The lowest result was corrected for atmospheric pressure.

The flash point of the test substance is 104°C.

Description of key information

The substance is NOT classified as flammable liquid neither according to CLP Regulation criteria, nor to UN GHS.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
104 °C

Additional information

A fully reliable experimental study, conducted according to a recognized ISO/EC method and under GLP, is available. It is therefore considered as a key study. The result is retained as key data for purpose of CSA.

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