It pays particular attention to electrical, mechanical and hydraulic characteristics of swivels. This document applies to fuels of subdivision Group IIA according to EN ISO/IEC 80079-20-1 and also aqueous urea solution in accordance with ISO 22241-1. The requirements apply to swivels at ambient temperatures from −20 °C to +40 °C with the possibility for an extended temperature range. This document applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapour. This document also addresses electrical and mechanical hazards of swivels.
