Results and discussion

Pyrophoric solids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.
Pyrophoric liquids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.

Any other information on results incl. tables

The determination of the flammability of the test item was performed in accordance with Council Regulation (EC) No. 440/2008, 30 May 2008, Part A, Methods for the determination of physico-chemical properties, A. 10 Flammability (solids).

 

In contact with the ignition source, RS-Pantolactone melted immediately and could not be ignited with a flame.

 

Therefore, no main test was performed.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
Based on the results of this study, RS-Pantolactone can not be considered as highly flammable according to the criteria of the guideline.
Executive summary:

RS-Pantolactone could not be ignited with a flame during the preliminary test (contact time of about 2 minutes).

 

Therefore, no main test was performed.

 

Based on the results of this study, RS-Pantolactone can not be considered as highly flammable according to the criteria of the guideline.
