Classification of gas appliances according to the method of supplying combustion air and of evacuation of the combustion products (types)
SIST EN 1749:2020

This document gives details for the classification of gas appliances according to the method of supplying combustion air and of evacuating the combustion products (types). This classification refers to gas appliances that are intended to be installed within buildings and/or outside of the building .
The document classifies appliances as type A, B or C according to the basic principle for the evacuation of the combustion products and air inlet.
This document is the reference for the harmonization of product standards, for the preparation of installation standards and for the common understanding of the types of gas appliances.
This document is neither an installation standard nor a product standard.
In references to a gas appliance or gas appliances connected via "its" or "their" duct or ducts, it is intended that the air inlet duct and/or the discharge duct for carrying any combustion products are part of the gas appliance. This means that such ducts are certified together with the gas appliance. Informative Annex C identifies appliance types that are designed for connection to separate chimney products, which may be part of the construction of the building.
In terms of this document, a "single duct" is a flue duct designed and capable of discharging the combustion products and/or air inlet duct for the air supply for only one appliance.
In terms of this document, a "common duct" is a flue duct designed and capable of discharging the combustion products and/or air inlet duct for the air supply for more than one appliance.

Gas supply systems - Gas installation pipework with an operating pressure greater than 0,5 bar for industrial installations and greater than 5 bar for industrial and non-industrial installations - Part 2: Detailed functional requirements for commissioning, operation and maintenance
SIST EN 15001-2:2023

This European Standard specifies detailed functional requirements for the commissioning, operation and maintenance of
-   industrial gas installations and assemblies with an operating pressure greater than 0,5 bar and of
-   non-industrial gas installations (residential and commercial) with an operating pressure greater than 5 bar,
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 European Standard also covers the pipework to the inlet connection of a gas appliance that is not included within the scope of the appliance standard.
NOTE   The use of the term installation and pipework is interchangeable.
Apart from the exceptions stated below, 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 EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European Standards, this European Standard applies.
In this European Standard, the term "gas" refers to combustible gases, which are gaseous at 15 °C and 1 013 mbar absolute atmospheric pressure. 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 as classified in Table 1 of EN 437:2003+A1:2009. The given values are considered as normal conditions for all volumes given in this standard.
This European Standard is applicable to installation pipework for the carriage of:
-   processed, non-toxic and non-corrosive natural gas according to EN 437:2003+A1:2009 and EN 16726 -Gas infrastructure - Quality of gas - Group H”,
-   vaporized LNG,
-   biomethane, complying with EN 16723-1,
-   vaporized LNG.
NOTE   The specification of vaporized LNG is equal to that of natural gas as classified in EN 437:2003+A1:2009.
This European Standard does not cover pipework for hydrogen rich gases that fall outside the definitions within EN 437:2003+A1:2009. LPG storage vessels (including all ancillaries fitted directly to storage vessels) are excluded. Also excluded are LPG installations and sections of LPG installations operating at vapour pressure (e.g. between the storage vessel and its pressure regulator).
In this European Standard, all pressures are gauge pressures unless otherwise stated.
This European Standard specifies common basic principles for gas supply systems. 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.
For gas installations within the scope of this standard, national legislation and regulations have to be taken into account.
Functional requirements for design, selection of materials, construction, inspection and testing of industrial gas installations and assemblies with an operating pressure greater than 0,5 bar and of gas installations greater than 5 bar in buildings and areas intended for residential, commercial, public and mixed uses are described in EN 15001-1.
Generally, additional safety precautions may be necessary where non odorized gas is used. For non-industrial purposes, the gas should be odorized.

Gas Infrastructure - Gas installation pipework with an operating pressure greater than 0,5 bar for industrial installations and greater than 5 bar for industrial and non-industrial installations - Part 1: Detailed functional requirements for design, materials, construction, inspection and testing
SIST EN 15001-1:2023

This European 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 pipework to the inlet connection of a gas appliance that is not included within the scope of the appliance standard.
NOTE 1   The use of the term installation and pipework is interchangeable.
Apart from the exceptions stated below, 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 (all parts) 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 European 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 as classified in EN 437:2003+A1:2009, Table 1. The given values are considered as normal conditions for all volumes given in this standard.
This European Standard is applicable to installation pipework for the carriage of:
-   processed, non-toxic and non-corrosive natural gas according to EN 437:2003+A1:2009 and EN 16726 "Gas infrastructure - Quality of gas - Group H";
-   vaporized LPG;
-   biomethane, complying with EN 16723 1;
-   vaporized LNG.
NOTE 2   The specification of vaporized LNG is equal to that of natural gas as classified in EN 437:2003+A1:2009.
This European Standard does not cover pipework for hydrogen rich gases that fall outside the definitions within EN 437:2003+A1:2009.
LPG storage vessels (including all ancillaries fitted directly to storage vessels) are excluded. Also excluded are LPG installations and sections of LPG installations operating at vapour pressure in the liquid state (e.g. between the storage vessel and any pressure regulator).
In this standard, all pressures are gauge pressures unless otherwise stated.
This standard has been harmonized to address the essential safety requirements of the Pressure Equipment Directive (PED, 2014/68/EU [formerly 97/23/EC]) relevant for the joining of gas installation pipework (assemblies) falling within the scope of the PED. These are listed in Annex ZA. However, "this Directive does not cover the assembly of pressure equipment on the site and under the responsibility of the user, as in the case of industrial installations" (PED, Preamble, 7th recital, last paragraph).
Although in this respect, the standard takes into account the essential safety requirements of the PED, no inference can be drawn from this as to whether or not the installation or parts of the installation falls within the scope of the PED. Reference should therefore be made to the PED and relevant national legislation.
This European Standard specifies common basic principles for gas supply systems. Users of this European Standard should be aware (...)

Gas meters - Conversion devices - Part 1: Volume conversion
SIST EN 12405-1:2022

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.
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 3.1.20.1 and 3.1.20.2.
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.
