EC number: 265-198-5 | CAS number: 64742-94-5 A complex combination of hydrocarbons obtained from distillation of aromatic streams. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 165°C to 290°C (330°F to 554°F).

Materials and methods
- Principles of method if other than guideline:
- This test determines the lower flammable limit of a vapour in air at atmospheric pressure. The sample is allowed to equilibrate with air in a glass vessel. A spark is then passed between electrodes for 0.5 seconds. The results are quoted as % volume of gas required per volume air.
- GLP compliance:
- yes

Results and discussion
Flammable gases (Lower and upper explosion limit)
- Parameter:
- lower explosion limit
- Value:
- 1.05 % (not further specified)

Applicant's summary and conclusion
- Conclusions:
- The lower flammability limit of pyrolysis C5 has been determined to be 1.05 % v/v in air at 98.9 kPa and 35°C.
- Executive summary:
This study was conducted to GLP and is clearly described. The test determined the lower flammability limit of pyrolysis C5 vapour.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
