Interpretation of results:
GHS criteria not met
Conclusions:
In a closed cup test, conducted according to EU Regulation (EC) 440/2008, Annex Part A test A9, ASTM D 3828 and to GLP, a flash point temperature for Alfalfa, ext. was determined as No flash to boiling.

Based on the results from flash point and boiling point tests Alfalfa ext. does not require classification as a flammable liquid according to CLP Regulation (EC) No 1272/2008.
Executive summary:

A closed cup method, conducted according to EU Regulation (EC) 440/2008, Annex Part A test A9, ASTM D 3828 and to GLP, was performed to determine the flash point temperature of Alfalfa, ext.

In the test conducted according to EU Regulation (EC) 440/2008, Annex Part A test A9 (Procedure B), the sample was heated at a rate of 1 to 1.6°C per minute with continual stirring at 250 ±10 rpm in a closed cup (volume ca. 100 cm3). A small flame with a diameter of 3.2 to 4.8 mm was directed into the cup containing the sample, at regular intervals, with simultaneous interruption of stirring. The sample foamed and expanded in the cup. Since the flash point temperature was determined as No flash to boiling, the SetaFlash method was employed according to ASTM D 3828 method.

The sample was introduced into the cup and maintained at the expected flash point. After a specified time a test flame was applied and the observation made was whether or not a flash occurred. Then sample was removed from the cup, the cup cleaned, and a fresh sample was then introduced and tested. This procedure was repeated until the flash point was established within 5°C (9°F) and was then repeated at 1°C (2°F) intervals until the flash point was determined to the nearest 1°C (2°F).

Again, the flash point temperature of Alfalfa, ext. was determined as Not flash to boiling.

Description of key information

Flash point: No flash to boiling

Key value for chemical safety assessment

Additional information

A closed cup method, conducted according to EU Regulation (EC) 440/2008, Annex Part A test A9, ASTM D 3828 and to GLP, were performed to determine the flash point temperature of Alfalfa, ext.

Both methods determined the flash point temperature of Alfalfa, ext. as No flash to boiling.

Based on the results from flash point and boiling point tests Alfalfa, ext. does not require classification as a flammable liquid according to CLP Regulation (EC) No 1272/2008.
