Most people will have heard about new regulations coming into force relating to controlling the use of organic solvents. These are officially termed the Solvent Emissions Directive (SED), but are sometimes colloquially termed the VOC (volatile organic compound) regulations. The full force of the regulations comes in by October 2007, but the regulations are being phased in gradually - some parts apply already. A VOC is defined officially in terms of the vapour pressure, but as a rough rule of thumb, any solvent or other organic compound with a boiling point of less than 250℃ is classified as a VOC in Europe.
