The flash point of the test item has been determined to be 57.5°C (330.65 K) (average of duplicate determinations).


 

Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Remarks:
Category 3 (flammable liquid) based on CLP criteria
Conclusions:
The flash point of the test item was determined to be 57.5°C (330.65 K).
Executive summary:

The flash point of the test substance was determined in a GLP study according to EU Method A.9 (Flash-Point), using a  non-equilibrium closed cup method (ISO 2719-B).


The flash point is given as the mean value of two determinations. The measured flash point is therefore 57.5°C at 101.3 KPa (corresponding to 330.65 K).


The flash point of test substance is below the classification thresholds of 60°C of both the Regulation (EC) No. 1272/2008 (CLP criteria) and the UN Globally Harmonised System (GHS).


Therefore the test substance is classified as a flammable liquid, category 3, according to both the CLP criteria and the UN Globally Harmonised System (GHS).


 

Description of key information

The substance is classified as a Flammable Liquid Category 3 according to Regulation (EC) N°1272/2008 (CLP criteria).


The substance is classified as Flammable Liquid Category 3 according to UN Globally Harmonized System (GHS criteria).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
57.5 °C

Additional information

A fully reliable GLP experimental study, conducted according to the recognized EU A.9 method, using a non-equilibrium closed cup method (ISO2719) 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.
