Gas systems
As a generally recognised rule-setter in public gas supply, the DVGW has formulated the technical requirements for access to gas networks.
The safety of gas installations requires special attention. The DVGW rules and regulations ensure that the generally recognised rules of technology are applied in practice and that a high level of safety is ensured.
The pipelines of the gas network must be maintained at regular intervals and, if necessary, rehabilitated. You will find DVGW codes of practice and standards on all these topics in this section.
G 280 Technical Rule 12/2018
114,55 €*
This Technical Rule G 280 applies to all gases
covered in DVGW Codes of Practice G 260 and G 262
respectively Standards DIN EN 16723-1 and -2 as
well as DIN EN 16726 and all gases used for the
supply
via pipeline system of the general public and
other consumers with a comparable level of
safety.
When using sulfur-containing odorants, the fact
shall be taken into account that the entailed
increase of
the sulfur content in the gas is undesirable for
some applications, such as its use as basic
material in the
chemical industry.
Industrial companies using natural gas
exclusively on company premises can forego
odorization if the
operator utilizes other measures to maintain the
industrial gas plant or system’s safety.
When switching from one odorant to another,
special attention shall be paid to Section 9.
The calibration of measuring devices for odorant
control requires test gases which are detailed in
Section
10.
G 472 Technical Rule - Standard 03/2020
64,20 €*
The European standardisation activities of the CEN/TC 234 necessitated the technical and editorial Revision of the national set of gas supply rules, with the objective being to eradicate contradictions and harmonise them with the requirements of the European standards and the formally amended framework conditions, ensuring at the same time that the application of the DVGW Set of Rules will also meet the requirements of the European standards that regulate the distribution of gas.Where reasonable and necessary, the requirements of this Standard G 472 have been harmonised with those of DVGW Standard G 462, including, among other things, the revision of minimum distances and the requirement for acceptance test certificates 3.1 in accordance with DIN EN 10204 for components for operating pressures above 5 bar.
GW 381 Technical Rule - Standard 05/2015
41,32 €*
For the purposes of this Standard GW 381, the term minimum requirements implies that further requirements can ensue from technical rules and legal provisions and/or that the ordering party may stipulate further requirements, in particular in the presence of special features or needs for protection or other constraints. The optional criteria shall, without claiming to be exhaustive, be considered guidance for the ordering party who shall decide on the need for further requirements. If a company consists of several units, this technical rule applies to the units in charge of underground construction and, without exception, to independent subsidiaries as well. A subsidiary shall be assumed to be independent if, in effect, it actually controls most operations and/or if the head office of the company is unable to provide the supervision of the staff and the construction sites as required.
G 2000 Technical Rule - Standard 05/2017 -PDF file-
82,05 €*
This DVGW Standard G 2000 integrates into the existing structure of laws, ordinances and technical rules on the design, construction, operation and maintenance of gas supply networks. It follows the principle of subsidiarity and represents - together with the DVGW Set of Rules and other relevant technical regulations - the minimum technical requirements for the interoperability of and connection to systems of the gas supply network in an objective and unbiased way.The requirements of DVGW Standard G 262 and DVGW Guideline G 292 shall be observed in respect of the injection of renewable gases into public gas supply networks.The overall recognised technical rules continue to apply in full to the design, construction, operation and maintenance of gas supply networks and systems.
G 450 Guideline 09/2017
64,20 €*
This Guideline G 450 shall be used together with DVGW Standard G 466‑1. It intends to promote a standardised approach to pigging gas pipelines that operate under positive operating pressure and contain a product. This Guideline is based on the long‑standing, tried and trusted safety philosophy and experience of the German gas sector.
DIN CEN/TR 17797 09/2022 - pdf-file -
192,50 €*
This document DIN CEN TR 17797 is written in preparation of
future standardization and provides guidance on how injection of H2 into the
gas infrastructure can impact processes from the input of gas into the on-shore
transmission network up to the inlet connection of gas appliances.
G 459-2 Technical Rule - Standard 11/2015
64,20 €*
This Technical Rule G 459‑2 applies to the design, installation, testing, commissioning, operation and maintenance of gas pressure regulating systems within the scope of DVGW Standard G 459‑1 with inlet pressures up to 5 bar1 and a maximum nominal flow rate of 200 m3/h under normal conditions for the supply of residential and office buildings, council housing as well as mixed‑use buildings and buildings housing public, cultural and commercial facilities to the extent that these are comparable to buildings of residential use with gases whose properties meet the requirements of DVGW Standard G 260, with the exception of liquefied petroleum gas (LPG)2, and which are supplied by public gas utilities. This Standard does not cover industrial production plants.
G 451 Technical Information - Guideline 09/2016
64,20 €*
The regulations in this Guideline G 451 shall be observed when planning and constructing gas transmission pipelines in conjunction with statutory procedures such as regional planning procedures und planning permission hearings.
G 213 Technical Rule - Standard 10/2013
64,20 €*
This Standard shall also apply, mutatis mutandis, to gas mixing plants that supply process gas to trade and industry and to industrial gas mixing plants for in‑house mixed‑gas supply.Gas mixing plants are frequently integrated into gas measurement and pressure reduction stations, which latter shall meet the specifications of DVGW Standards G 491 and G 492. In other words, most of the requirements specified in these Standards will also apply to gas mixing plants. All other requirements that go beyond the scope of G 491 and G 492 are described in this Technical Rule at hand, which first and foremost complements DVGW Standard G 491.
G 415 Technical Rule - Standard 09/2015 -PDF file-
64,20 €*
This DVGW Standard can be used as a guideline as it summarises the minimum requirements specified in the DVGW Sets of Rules that shall be observed by design firms, specialist contractors, operators and the involved authorities during the design, construction and operation of gas pipework for the transmission of untreated or partially treated biogas. The clause on Design also draws attention to the fact that the pertinent approvals and / or permissions shall be obtained prior to the start of construction of pipework planned to cross e. g. water bodies, roads and railways.Gases produced by fermentation processes such as e. g. biogases obtained from agriculture that are generally used to meet internal requirements and / or to power decentralised systems such as e. g. combined heat and power plants, are untreated or partially treated biogases that are not considered gases in accordance with DVGW Standard G 260.Nonetheless, the documents that form part of the DVGW Set of Rules that are referred to in this Standard shall also be applied to pipelines that transmit untreated or partially treated biogas.
