European foreword This document (EN 16723-1:2016) has been prepared by Technical Committee CEN/TC 408 “Natural gas and biomethane for use in transport and biomethane foe injection in the natural gas network”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2017, and conflicting national standards shall be withdrawn at the latest by May 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. EN 16723 consists of the following parts, under the general title “Natural gas and biomethane for use in transport and biomethane for injection in the natural gas network”: — Part 1: Specifications for biomethane for injection in the natural gas network — Part 2: Automotive fuel specifications According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

3.8 methane number MN rating indicating the knocking characteristics of a gaseous fuel Note 1 to entry: MN has a similar use as the octane number for petrol. Note 2 to entry: MN expresses the volume percentage of methane in a methane/hydrogen mixture which, in a test engine under standard conditions, has the same tendency to knock as the gaseous fuel to be examined. 3.9 natural gas complex gaseous mixture of hydrocarbons, primarily methane, but generally includes ethane, propane and higher hydrocarbons, and some non-combustible gases such as nitrogen and carbon dioxide Note 1 to entry: Natural gas can also contain components or contaminants such as sulfur compounds and/or other chemical species. 3.10 natural gas network either transmission network or local distribution system 3.11 non-grid sourced natural gas natural gas non coming from the natural gas network 3.12 odorization addition of odorants to gas (normally odourless) to allow gas leaks to be recognized by smell at trace levels (before accumulating to dangerous concentrations in air) 3.13 syngas gas, comprising principally of carbon monoxide and hydrogen, obtained from gasification of fossil fuel 3.14 upgrading of biogas removal of carbon dioxide and contaminants from biogas 3.15 water dew point temperature temperature above which no condensation of water occurs at a specified pressure 3.16 Wobbe index volumetric-basis heating value, at specified reference conditions, divided by the square root of the relative density at the same specified metering reference conditions SIST EN 16723-1:2017
