This European Standard shall be
29、 given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2018, and conflicting national standards shall be withdrawn at the latest by January 2018. Attention is drawn to the possibility that some of the elements of this document
30、 may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1359:1998. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports
31、essential requirements of EU Directive. For relationship with EU Directive, see informative Annex ZA, which is an integral part of this document. Significant changes from the previous editions include: conformity with the MID 2014/32/EU regarding declared errors of the same sign and testing Qminat t
32、he minimum and maximum declared gas temperatures; corrosion protection restructured; endurance testing for residential meters revised to reflect better the in-service life; provision for meters with electronic indexes and integrated valves, and requirements for additional functionalities as given in
33、 EN 16314; adhesion testing of labels. Annex B has been restructured to give additional requirements for meters provided with a built-in gas temperature conversion device. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to
34、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, Rom

BS EN 1359:2017EN 1359:2017 (E) 6 1 Scope This European Standard specifies the requirements and tests for the construction, performance, safety and production of class 1,5 diaphragm gas meters (referred to a
36、s meters). This applies to meters with co-axial single pipe, or two pipe connections, that are used to measure volumes of fuel gases, which are within the limits of test gases of the 1st, 2nd and 3rd families described in EN 437. The meters have maximum working pressures not exceeding 0,5 bar and ma
37、ximum actual flow rates not exceeding 160 m3h1over a minimum ambient temperature range of 10 C to 40 C and a gas temperature range as specified by the manufacturer with a minimum range of 40 K. This standard applies to meters with and without built-in temperature conversion that are installed in loc
38、ations with vibration and shocks of low significance (see MID Annex 1 Chapter 1.3.2 (a), class M1). It also applies to meters in: closed locations (indoor or outdoor with protection as specified by the manufacturer) both with condensing humidity, or with non-condensing humidity; or, if specified by
39、the manufacturer: open locations (outdoor without any covering) both with condensing humidity and with non-condensing humidity; in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial and light industrial buildings (see MID Annex 1 Chapter
40、1.3.3 (a), class E1). Unless otherwise stated, all pressures given in this document are gauge pressure. Requirements for electronic indexes, batteries, valves incorporated in the meter and other additional functionalities are given in EN 16314. Unless otherwise stated in a particular test, the tests
41、 are carried out on meters that include additional functionality devices intended by the manufacturer. Clauses 1 to 9 and Annexes B and C are for design and type testing only. NOTE The content of OIML Publication International Recommendation R 137 has been taken into account in the drafting of this
42、standard. If no specific requirements are given for test equipment, the instruments used should be traceable to a national or international reference standard and the uncertainty (2) should be better than 1/5 of the maximum value of the parameter to be tested. For differential results the repeatabil
43、ity (2)/resolution should be better than 1/5 of the maximum value of the parameter to be tested. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
