Description of key information
Data on physical properties were obtained from a number of secondary sources. The data in these secondary sources are based on a critical evaluation of peer-reviewed data and the selected values are considered to be reliable and representative of the property under investigation. Information in the review process was documented in the introduction of the source. The use of Klimisch codes (Klimischet al., 1997), was extended to these secondary sources and a reliability code of (2)valid with restrictionswas assigned when using the authoritative secondary source.
The boiling point for n-pentane is 28 -70°C and the flashpoint is -20°C. These values have been agreed by the consortium to represent the substance and are supported by secondary sources. According to the CLP legislation (2008) a liquid with a flash point of <23°C and a boiling point of <35°C is classified as a Category 1 flammable liquid with the hazard statement "extremely flammable liquid and vapour".
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
