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 213 Technical Rule - Standard 10/2013
55,79 €*
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 260 Technical Rule 09/2021 -PDF file-
99,55 €*
This Technical Rule G 260 specifies the
requirements for the quality of fuel gases used
in the supply of the general public with gas and
sets the parameters for gas delivery, gas
transportation, gas distribution, gas storage,
operation of gas plants/systems and gas
appliances for commercial and industrial gas
applications as well as for development,
standardization, and testing.
Gases transported in separate pipelines which are
not used in the supply of the general public, or
are used as energy carrier or resource, and/or
are used in special gas appliances are not
subject to the scope of this Technical Rule.
G 265-1 Code of Practice 03/2014
99,55 €*
This Code of Practice G 265‑1 serves as a basis for designing, manu‑facturing, constructing, testing and commissioning plants for upgrading biogas to natural gas quality, plants for injecting these gases into gas transmission and distribution systems, and plants for the refeeding of gas into the upstream gas supply network. This DVGW Code of Practice provides a summary overview of the minimum requirements on the technical safety of plants and components required for the utilisation of biogas, from upgrading plants through to compressor stations; pressure control, href= https://shop.wvgw.de/509052 >here. the injection into the gas supply network as added or substitute gas. At the same time, one focus was on the indispensable coordination between the ? generally different ? plant operators.
G 280 Technical Rule 12/2018 -PDF file-
99,55 €*
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 402 Code of Practice 07/2011
71,30 €*
This Code of Practice G 402 has been elaborated by the ?G 401? project group within the Technical Committee on ?Gas distribution?. It shall serve as a basis for the collection and evaluation of data to devise mainte‑nance strategies for gas distribution systems. Maintenance comprises inspection as well as service and repair activities. The respective DVGW Codes of Practice define the fundamental principles applying to inspection and service activities. This Code of Practice G 402 focuses on the collection and evaluation of data that form the main basis for repair planning. The requirement for gas distribution systems to be permanently kept in a condition guaranteeing their technical safety and reliability necessitates timely and ongoing maintenance and service activities. These activities shall be planned in advance. Maintenance strategies shall be integrated into corporate processes, the collection of major grid data being a prerequisite for introducing such strategies. Beyond this, condition‑based maintenance requires ascertaining and evaluating grid conditions by means of adequate systems. This Code of Practice describes the fundamental procedure for ascertaining, collecting and evaluating maintenance‑relevant data and offers examples illustrating how to prepare and evaluate them. This Code of Practice does not specify a standard data collection procedure for creating a planning concept in conformance with href= https://shop.wvgw.de/508331 >here.
G 410 Code of Practice 05/2017

The new database contains all relevant information and features a user interface suitable for data entry and data provision. The reporting procedures are supervised and ensured by the DVGW and apply to both pipelines with a maximum allowable operating pressure of above 16 bar and analogously to gas‑related facilities, according to the recommendations of the International Gas Union.
