The flammability is between 1.4 and 7.8 % v/v for Hydrocarbons, C5, n-alkanes, isoalkanes, based on calculated values. This has been agreed by the consortium to represent the substance.

Justification for classification or non-classification

The boiling point range for 2 -methylbutane is 25 to 65oC and the flashpoint is 0oC. According to the CLP legislation (2008) a liquid with a flash point of <23oC and a boiling point of <35oC is classifiable as a Category 1 with the hazard statement "extremely flammable liquid and vapour".

The boiling point range for cyclopentane is 48 to 50oC and the flashpoint is -20oC. According to the CLP legislation (2008) a liquid with a flash point of <23oC and a boiling point of >35oC is classified as a Category 2 flammable liquid with the hazard phrase "highly flammable liquid and vapour".

The boiling point for n-pentane is 28 to 70oC and the flashpoint is -20oC. According to the CLP legislation (2008) a liquid with a flash point of <23oC and a boiling point of <35oC is classifiable as a Category 1 flammable liquid with the hazard phrase "extemely flammable liquid and vapour".

The boiling point range for hydrocarbons C5 is 14 to 50°C and the flashpoint is -20°C. According to the CLP legislation (2008) a liquid with a flash point of <23°C and a boiling point of <35°C is classifiable as a Category 1 flammable liquid with the hazard phrase "extremely flammable liquid and vapour".
