This European Standard describes common principles for pressure testing, commissioning and decommissioning of gas infrastructures as covered by the functional European Standards of the Technical Committee CEN/TC 234, see Annex B. They have been extracted from the detailed codes of practice and operating manuals in the member countries. This European Standard does not cover installation pipework which is covered by EN 1775. The specified procedures are applicable to strength testing, tightness testing and combined testing. Test pressure levels, test periods and acceptance criteria are not covered by this European Standard. Additional measures or different methods of testing, commissioning or decommissioning can be required by legislation of the individual member countries or at the discretion of the pipeline operator. This European Standard specifies common basic principles for gas infrastructure. Users of this European Standard should be aware that more detailed national standards and/or code of practice may exist in the CEN member countries. This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this European Standard, the national legislation/regulation should take precedence as illustrated in CEN/TR 13737 (all parts). CEN/TR 13737 (all parts) give: clarification of all legislations/regulations applicable in a member state; if appropriate, more restrictive national requirements; a national contact point for the latest information.

This European Standard specifies the requirements and tests for the construction, performance, safety and conformity of conversion devices used to determine the energy of fuel gases described in the Table 1, including those of the 1st and 2nd families according to EN 437. The energy conversion device (ECD) considered in This standard consists of an energy calculator (EC) and is associated with the following devices and/or functions: a volume conversion device (VCD) or a flow computer used as gas meter conversion, either conforming to EN 12405-1:2005+A2:2010, or to prEN 12405-3, for high accuracy measurements; a calorific value determination device (CVDD). Requirements for type approval tests of the devices, not included in the above-mentioned standards are described in appropriate annexes specified in Table 6. For the purpose of this European Standard, the term "volume conversion devices" (VCDs) includes flow computers (FCs). A single calculator may undertake the volume conversion functions for different metering lines.

This Technical Report outlines recommendations for """"smart gas meters"""", specifies recommendations where there is clear consensus, and identifies areas where there are barriers to standardisation. It indicates how functions may be implemented in a harmonized way if they are selected. It does not seek to select which functions are to be implemented in a smart meter. The report covers simple to complex implementations of smart metering.This Technical Report is applicable to 1st, 2nd and 3rd family gases according to EN 437.

1.1 This specification defines requirements for the data used in the tracking and traceability base-62 encoding system and the format of the resultant code to characterize various components used in fuel gas piping systems. 1.2 The final output of this specification is a 16 digit alpha-numeric code that defines a standardized approach or methodology for encoding certain characteristics of components that have been established based on consensus recommendations from the respective stakeholder group members. The means of marking or affixing the code to the components, and the means of reading and/or transferring the data or codes are outside the scope of this specification. Note 18212;To facilitate compliance with this specification, a web based application has been developed to manage and maintain unique identifiers for certain characteristics including manufacturer identification numbers, material types, and component types as specified in this document. The web based application also provides a calculator to help users and manufacturers apply the base-62 encoding system outlined in this specification. The URL for the website is: http://www.componentid.org. 1.3 The web based application is only intended to serve as a useful resource for managing the respective manufacturer identification numbers, codes, and other identifiers as per this specification. Any changes to the contents of the web based application are contingent upon subsequent changes to this specification. This specification shall have primacy.

This European Standard specifies the requirements and tests for the construction, performance, safety and conformity of gas-volume electronic conversion devices associated to gas meters, used to measure volumes of fuel gases of the 1st and 2nd families according to EN 437. This European Standard is intended for type testing, the detailed relevant provisions of which are given in Annex A. Only three kinds of conversion are treated in this European Standard: conversion as a function of temperature only (called T conversion); conversion as a function of the pressure and of the temperature with constant compression factor (called PT conversion); conversion as a function of the pressure, the temperature and taking into account the compression factor (called PTZ conversion). This document is not relevant to temperature conversion integrated into gas meters which only indicate the converted volume. EN 12405-2 for energy conversion is in preparation. Gas-volume conversion devices consist of a calculator and a temperature transducer or a calculator, a temperature transducer and a pressure transducer locally installed. For application of this European Standard, a conversion device may be, as a choice of the manufacturer, considered as a complete instrument (Type 1) or made of separate elements (Type 2), according to the definitions given in 3.8.1 and 3.8.2. In this last case, the provisions concerning pressure transducers, temperature sensors and temperature transducers are given in Annexes B, C and D respectively. Any conversion device can provide an error curve correction for a gas meter. NOTE When rendering an account to an end user the readings from the conversion device can be used in conjunction with the readings from a gas meter conforming to EN 1359, EN 12480, or EN 12261, as appropriate, or to any other appropriate and relevant international or national standard for gas meters, without prejudice of national regulations.
