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 (...)

Industrial Gas Installation - Guideline
SIST-TP CEN/TR 16787:2015

This Technical Report applies to safety and operational topics for equipment and pipework systems installed within industrial premises which may be used for process and non-process applications such as Heating, Power Generation, Incineration, etc.
It is applicable to a range of combustible gases used within an industrial environment. The gas plant may include normal combustion with air and/or oxygen, catalytic oxidation or cracking (e.g. as in a refinery).
The user of gas equipment and pipework systems has a responsibility to ensure the safety of the design, of plant operation and plant maintenance.
For piped supplies of gas to a site this Technical Report applies to the system downstream of the ‘point of delivery’. The term, ‘point of delivery’ refers to the isolation valve (or combination of regulator and isolation valve) located before or after the metering station, as will be defined by the particular EU member state national legislation.
The guidance in this Technical Report may also apply to gases generated for the sites own use, such as coke oven gas, site bio-gas plant, site LPG/air plant etc.

Gas-Specific Environmental Document - Guideline for incorporating within standards to minimize the environmental impact of gas infrastructure across the whole life cycle
SIST-TP CEN/TR 16388:2013

The gas supply companies, in the widest sense of their activities (production, transport, distribution), have a long tradition in ensuring that networks and facilities are operated according to well-defined procedures. These procedures are the centrepiece of quality management systems. They are based on the general criteria of the series ISO 9000 and are currently being developed gas-specifically as EQAS (European Quality Assurance System) in CEN/TC 234 in order to adhere more efficiently to the procedures peculiar to the gas activities. Companies are more and more inclined to take into account environmental aspects, since the series ISO 14000 resulting in EMAS (Environment Management System) have a similar structure, and the measures to be taken are directly linked to the technical operations and therefore cannot be dissociated from them.
Environmental issues are expected to feature increasingly in CEN standardisation as the European Commission and its affiliated Member States press ahead with an array of proposals for potential directives. These directives are aimed at boosting the reduction of energy consumption, reducing emissions to air/water and, more generally, at forcing industry to consider any process which may have adverse impacts on the environment.
The CEN Sector Forum Gas Infrastructure (CEN/SFG_I) will take this opportunity to demonstrate through EQAS, the effectiveness of gas companies in this area who are continuously looking for the best technologies (although natural gas is by nature an environmentally friendly energy in comparison with other fossil fuels).
Environmental guides are other tools which CEN has introduced through its Technical Board Resolution C108/2000, by requesting the sector forums and their attached Technical Committees to implement the European Commission policy regarding standardisation.
This Technical Report, intended to be used when drafting or reviewing the standards of CEN/TC 234, does not claim to either lay down dedicated requirements for each operation described in each standard nor to set limit values (e.g. emissions) that would be the specific task of the experts in the working group concerned.
Rather, it serves the purpose of triggering an in-depth reflection on the environmental consequences whenever an operative action is planned or being executed. As a way of implementing the basic scheme it was agreed to accommodate the environmental indicators (EIs marked a to i) in the fields of Table 1 (numbered 1 to 49) which match operations/processes with installation/plant. For each field of the Table referenced then by a number and letters, the corresponding requirements are precisely described in Table 2 "Gas-specific Environmental Requirements".
