ANNEX II CONTENT OF THE MEMBER STATES COMMUNICATIONS OF THE GAS SUPPLY CONDITIONS 1. The communications of the Member States to the Commission and the other Member States provided for in Article 4 shall have the following content: (a) (i) gross calorific value (GCV) in MJ/m 3 minimum/maximum; (ii) Wobbe index in MJ/m 3 minimum/maximum. (b) Gas composition by volume in % of the total content: — C 1 to C 5 content in % (sum) minimum/maximum; — N 2 + CO 2 content in % minimum/maximum; — CO content in % minimum/maximum; — unsaturated HC content in % minimum/maximum; — hydrogen content in % minimum/maximum. (c) Information on toxic components contained in the gaseous fuel. That communication shall also include either of the following: (a) supply pressure at the inlet of appliances in mbar: nominal/minimum/maximum; (b) (i) supply pressure at the point of delivery in mbar: nominal/minimum/maximum; (ii) admissible pressure loss in the end-user gas installation in mbar: nominal/minimum/maximum. 2. The reference conditions for Wobbe index and gross calorific value shall be the following: (a) combustion reference temperature: 15 °C; (b) volume measurement reference temperature: 15 °C; (c) volume measurement reference pressure: 1 013,25 mbar.
