- 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:

- 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 the
EEC Directive 92/69, EEC Publication No. L383, December 1992 and 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, R-Pantolactone melted immediately and could not be ignited
with a flame. A milky residue remained.
R-Pantolactone could not be ignited with a flame during the preliminary test (contact time of
about 2 minutes). Therefore, no main test was performed.
Applicant's summary and conclusion
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- R-Pantolactone can not be considered as "highly flammable".
- Executive summary:
R-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, R-Pantolactone can not be considered as "highly flammable"
according to the criteria of the guideline.
