Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- L-glutamic acid monopotassium salt monohydrate is not highly flammable in accordance with test EC A.10. criteria.
- Executive summary:
Preliminary screening test
The preliminary screening test was made todetermine if, on ignition by a gas flame, propagation by burning with flame or smouldering occurs. It was noted whether combustion propagates alongof the train within the 4 minutes test period.
The substance was formed into an unbroken strip or powder train aboutlong bywide byhigh on a non-combustible, non-porous and low heat-conducting base plate. A hot flame from a gas burner (minimum diameter,temperature of the flame was about) 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 melt but the sample did not ignite. Combustion did not propagate to the next part of the train. Result: NEGATIVE.
L-glutamic acid monopotassium salt monohydrate is not highly flammable in accordance with test EC A.10. criteria.
