Amendment to Sulphur in Liquid Fuels Regulations published by Nick Boley

The UK Government has published the Sulphur Content of Liquid Fuels (England and Wales) (Amendment) Regulations 2014 (SI 1975/2014), which amends the Sulphur Content of Liquid Fuels (England and Wales) Regulations 2007 (SI 79/2007).

This amendment, which had previously been enacted in Northern Ireland by the Sulphur Content of Liquid Fuels (Amendment) Regulations (Northern Ireland) 2014 (SR 147), restricts the sulphur content of heavy fuel oils to 1 % by mass, and the sulphur content of gas oils to 0.1 % by mass. It also deletes the previous schedule 8 “technical requirements for sample analysis”. Schedule 6 is amended as follows: “The reference method adopted for determining the sulphur content of fuels sampled pursuant to paragraph (1) shall be defined by ISO method 8754 (2003) or EN ISO 14596 (2007).”

ISO 8754:2003 covers the determination of the sulphur content of fuels by energy-dispersive x-ray fluorescence spectrometry, and has a working range of 0.03 % to 5% sulphur by mass.

EN ISO 14596:2007  covers the determination of the sulphur content of fuels and fuel additives by wavelength-dispersive X-ray fluorescence spectrometry and has a working range of 0.001 % to 2.5 % sulphur by mass.
