EN 15001-1:2023

This standard specifies detailed functional requirements for the design, selection of materials, construction, inspection and testing of industrial gas installation pipework and assemblies with an operating pressure greater than 0,5 bar, and non industrial gas installation pipework (residential and commercial) with an operating pressure greater than 5 bar in buildings, starting from the outlet of the network operator’s point of delivery up to the inlet connection to the gas appliance; normally the inlet isolation valve. This standard also covers the inlet connection to the gas appliance comprising of the pipework that does not fall within the scope of the appliance standard.
NOTE   The use of the term installation and pipework is interchangeable.
This standard applies to gas installations operating at ambient temperatures between - 20 °C and 40 °C and operating pressures up to and including 60 bar. For operating conditions outside these limitations, reference should additionally be made to EN 13480 for metallic pipework.
For industrial gas installations up to and including 0,5 bar and for non industrial (residential and commercial) gas installations up to and including 5 bar in buildings, EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European Standards, this standard applies.
In this standard, the term “gas“ refers to combustible gases, which are gaseous at 15 °C and 1 013 mbar absolute atmospheric pressure (normal conditions). These gases are commonly referred to as manufactured gas, natural gas or Liquefied Petroleum Gas (LPG). They are also referred to as first, second or third family gases (see Table 1 of EN 437:2003). The given values are considered as normal conditions for all volumes given in this standard.

Gas meters - Conversion devices - Part 1: Volume conversion
EN 12405-1:2021

This document 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 document 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 document:
-   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 applies for energy conversion.
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 document, 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 3.1.18.1 and 3.1.18.2.
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.
