    23、l standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internation

    24、al organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules

    25、 given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at le

    33、neral practice for manufactured gas and, subsequently, natural gas to be bought and sold on a volumetric basis. Much time and effort has therefore been devoted to developing the means of flow measurement. Because of the increasing value of energy and variations in gas quality, billing on the basis o

    34、f thermal energy has now become essential between contracting partners and the need to determine calorific value by measurement or calculation has led to a number of techniques. However, the manner in which calorific value data are applied to flow volume data to produce the energy content of a given

    35、 volume of natural gas has been far from a standardized procedure. Energy determination is frequently a necessary factor wherever and whenever natural gas is metered, from production and processing operations through to end-user consumption. This International Standard has been developed to cover as

    36、pects related to production/transmission and distribution/end user. It provides guidance to users of how energy units for billing purposes are derived, based on either measurement or calculation or both, to increase confidence in results for contracting partners. Other standards relating to natural

    37、gas, flow measurement, calorific value measurement, calculation procedures and data handling with regard to gas production, transmission and distribution involving purchase, sales or commodity transfer of natural gas can be relevant to this International Standard. This International Standard contain

    38、s ten informative annexes.

    39、(E) ISO 2011 All rights reserved 1Natural gas Energy determination 1 Scope This International Standard provides the means for energy determination of natural gas by measurement or by calculation, and describes the related techniques and measures that are necessary to take. The calculation of thermal

    40、 energy is based on the separate measurement of the quantity, either by mass or by volume, of gas transferred and its measured or calculated calorific value. The general means of calculating uncertainties are also given. Only systems currently in use are described. NOTE Use of such systems in commer

    41、cial or official trade can require the approval of national authorization agencies, and compliance with legal regulations is required. This International Standard applies to any gas-measuring station from domestic to very large high-pressure transmission. New techniques are not excluded, provided th

    42、eir proven performance is equivalent to, or better than, that of those techniques referred to in this International Standard. Gas-measuring systems are not the subject of this International Standard. 2 Normative references The following referenced documents are indispensable for the application of t
