other: Calculated data
Qualifier:
no guideline followed
Principles of method if other than guideline:
Extrapolated from published data. Calculated.
GLP compliance:
no
Conclusions:
The calculated lower and upper flammability range is respectively 0.7 and 6.3 v%.
Executive summary:

The calculated lower and upper flammability range is respectively 0.7 and 6.3 v%.

Endpoint:
flammable solids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid

Description of key information

A study is scientifically unjustified, since hydrocarbons, C7-C9, isoalkanes have a flash point below 23°C and a initial boiling point higher than 35°C and

therefore meets the criteria of Category 2 for flammability.

Key value for chemical safety assessment

Additional information

The upper and lower flammability limit was determined by extrapolation from published data as respectively 0.7 and 6.3 v%.

Justification for classification or non-classification

In accordance with REACH Annex XI this study is scientifically unjustified. The flammability of liquids is determined on the basis of their flashpoint (in combination with their boiling point), their ability to emit flammable gases upon contact with water and their pyrophoricity. The molecular structure of the substance does not contain groups that indicate potential reactivity with water or pyrophoric properties and handling of the substance indicates that this is the case. The flashpoint indicates that the substance is a Category 2- Highly flammable liquid. The substance was placed in this hazard class because it has a flash point below 23°C and a initial boiling point higher than 35°C and therefore meets the criteria of Category 2 for flammability.
