Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Experimental Date: 17 September 2019
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. The substance is adequately characterised. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Version / remarks:
Commission Regulation (EC) No 440/2008
Deviations:
no
Qualifier:
according to guideline
Guideline:
ISO 3679 (Determination of flash point - Rapid equilibrium closed cup method)
Version / remarks:
(2015) – Procedure B
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
signed on 15 Nov. 2018
Type of method:
equilibrium method closed cup
Flash point apparatus:
Setaflash apparatus
Dynamic viscosity of test material:
The viscosity of the test item appears to be similar to that of water.
Specific details on test material used for the study:
Storage conditions: Ambient temperature away from light. Kept in the original container.
Key result
Flash point:
101 °C
Atm. press.:
101.3 kPa

Pre-test

The flash point of the test item was estimated at 100.0°C during the pre-test.

First Determination

The flash point of the test item was detected at 100.0°C during the first determination.

An automatic correction was applied to the obtained result because the ambient pressure was not 101.3 kPa but 97.8 kPa.

With this correction, the flash point value is 101.0°C at 101.3 kPa.

The appearance of the test item left in the test cup did not change. No sign of decomposition or film formation was observed.

Second Determination

The flash point was detected at 100.0°C and an automatic correction was applied to the obtained result because the ambient pressure was not 101.3 kPa but 97.7 kPa.

With this correction, the flash point value is 101.0°C at 101.3 kPa.

The appearance of the test item left in the test cup did not change. No sign of decomposition or film formation was observed.

As the two determinations have the same value of the flash point, the selected value for this study is 101.0°C at 101.3 kPa.

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

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

The sample was heated at a gradient of +2°C/min in a temperature range around the value found in the pre-test, and ignition was tested every 2°C. The test was performed in duplicate, results were found identical.

The flash point of the test substance has been determined to be 101°C (corrected to normal atmP).

Description of key information

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

Key value for chemical safety assessment

Flash point at 101 325 Pa:
101 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EU/ISO guideline (rapid 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)
