Results and discussion

Flammable solids
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Aspartic Acid Sodium Salt Monohydrate – min. 98% - ADCF (L-Aspartic acid monosodium salt monohydrate) is not highly flammable in accordance with test EC A.10. criteria.
Executive summary:

Flammability (solids) was performed according to Standard Operating Procedure SPO/BC/08/b (editon 3) which corresponds to method EC A.10 Flammability (solids) [1].


 


Preliminary screening test


The preliminary screening test was made to determine if, on ignition by a gas flame, propagation by burning with flame or smouldering occurs. It was noted whether combustion propagates along 200 mm of the train within the 4 minutes test period.


The substance was formed into an unbroken strip or powder train about 250 mm long by 20 mm wide by 10 mm high on a non-combustible, non-porous and low heat-conducting base plate. A hot flame from a gas burner (minimum diameter 5 mm, temperature of
the flame was about 1000 °C) was applied to one end of the train until the train ignites or for a maximum of 2 minutes.


After applying the flame to the sample, the sample did not ignite. Combustion did not propagate to the next part of the train. Result: NEGATIVE


Aspartic Acid Sodium Salt Monohydrate – min. 98% - ADCF (L-Aspartic acid monosodium salt monohydrate) is not highly flammable in accordance with test EC A.10. criteria.
