Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

Key study data are available for each relevant physicochemical endpoint for the heavy fuel oils category. All substances in the category are viscous liquids with a characteristic odour (CONCAWE, 1998) at ambient temperature (20°C) and pressure (101.3 kPa). There is no guideline method available for this endpoint and data presented are based on visual observation, supported by data on melting point/pour point. The pour point for chemicals in this category is generally <30°C (CONCAWE, 1998) and the boiling point ranges from 160°C to >750°C (CONCAWE, 2010a). The density ranges from 840 to 1100 Kg/cm3at 15°C and the vapour pressure ranges from 0.02 to 0.79 kPa at 120°C (MW 330 to 500) and 0.06 to 0.86 at 150°C (MW 350 to 420) (CONCAWE, 2010a). 

 

Flash points for heavy fuel oils are generally 64 to 310°C (CONCAWE, 2010a) and the self-ignition temperature ranges from 220°C to 550°C (CONCAWE, 2010a). Heavy fuel oils do not meet EU CLP Regulation (EC. No. 1272/2008) classification criteria for flammability, explosivity or oxidising properties, and do not dissociate or form ionized species. The viscosity of substances in this category is typically >3 mm2/s at 100°C (CONCAWE, 2010a).

 

Based on information available on the properties of the substances that comprise the heavy fuel oils category of chemicals, specific data are not presented for the following endpoints: water solubility, partition co-efficient, surface tension, granulometry, flammability, explosiveness, oxidizing properties, stability in organic solvents and dissociation constant. Appropriate waiving statements are provided to indicate why data for these REACH endpoints are not applicable. The physico-chemical data presented are considered representative for the substances included in the category heavy fuel oils.
