In many countries, diesel fuel is standardised. For example, in the European Union, the standard for diesel fuel is EN 590. Diesel fuel has many colloquial names, most commonly, it is simply referred to as "Diesel". In the UK, diesel fuel for on-road use is commonly abbreviated "DERV", standing for "diesel-engined road vehicle", which carries a tax premium over equivalent fuel for non-road use. In Australia, diesel fuel is also known as "distillate", and in Indonesia, it is known as "Solar", a trademarked name by the local oil company Pertamina.
