DVGW Set of Rules Gas
G 459-2 Technical Rule - Standard 11/201555,79 €*
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.
DIN EN 15001-1 02/2011 (english version)294,20 €*
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 inlet connection to the gas appliance comprising of the pipework that does not fall within the scope of the appliance standard.
G 1001 Technical Guideline 03/201555,79 €*
Operators of gas infrastructures shall have at their disposal high‑performance equipment, qualified staff and well‑functioning quality assurance measures or, alternatively, subcontract qualified experts and monitor the execution of the respective services. Furthermore, they shall be organised in such a way as to ensure the safe, reliable, environmentally friendly and economically efficient operation of their business (DVGW G 1000 (A)). This Guideline G 1001 aims at supporting operators with the compilation and review of their own process‑oriented risk management. Within the scope of this risk management, existing risks shall be determined, analysed, evaluated and where necessary measures to reduce the risk shall be taken. DIN EN 31010 provides a detailed description of risk assessment procedures. The Technical Guideline takes this risk assessment procedure as a basis of orientation and transfers it to the needs of gas infrastructures. In view of multiutility companies, there is a close interlinking with existing regulations in the power, district heating and water sectors. Document structure and individual chapters were harmonised.href= https://shop.wvgw.de/509309 >here.
G 1002 Technical Guideline 02/201599,55 €*
This Guideline G 1002 describes the fundamentals of inhouse crisis management and offers relevant recommendations for operators as well as abundant information about the disaster and crisis management organisation of the local authorities. In the following, the term ?operator? will be used throughout regardless of the structure of ownership and type of installation. Operators shall have at their disposal high‑performance equipment, sufficiently qualified staff and robust quality assurance measures; alternatively, they shall subcontract qualified experts and monitor the execution of the outsourced service. Furthermore, they shall be organised in such a way as to ensure the safe, reliable, environmentally compatible and economically efficient operation of their business (DVGW G 1000 (A)). A risk management system with a focus on the individual gas supply processes will help meet these requirements (DVGW G 1001 (M)). Moreover, certain situations may arise that occur extremely rarely, are difficult to forecast and, therefore, impossible to make provisions for. Operators may not be able to control such situations without the involvement and help of the local authorities. It is impossible in such cases to act according to predefined instructions as such situations require operators to take appropriate decisions under consideration of all framework conditions relevant for the purposes of ensuring the operation of the plant. Crisis management is a tool designed with this purpose in mind; this Guideline G 1002 has been especially adapted by the DVGW to meet gas supply requirements. The implementation of an emergency and crisis management system outside normal organisation procedures is required for meeting this recommendation during emergencies and in times of crisis. This Guideline aims to enable operators to take action in an emergency or crisis so as to ensure to the greatest possible extent the continued supply of gas and the fastest possible restoration of normal operating conditions. The management tools required to achieve this goal are explained below. In due consideration of multiutility companies, this Guideline take into account existing regulations power, water and districtheating (cf. S1001 / S1002, W1001 / W1002, FW1001 / 1002).
G 2000 Technical Rule ? Standard 05/201771,30 €*
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 10/201355,79 €*
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 265-1 Code of Practice 03/201499,55 €*
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 265-3 Technical Guideline 05/201455,79 €*
href= https://shop.wvgw.de/509113 >here. This Guideline G 265‑3 shall apply to the design, construction, manufacture, construction, testing, commissioning and operation of plants for the injection of hydrogen into gas transmission and supply networks for gases in accordance with DVGW Code of Practice G 260, including the necessary service lines and ancillary equipment. This DVGW Guideline complements DVGW Code of Practice G 265‑1 and DVGW Guideline G 265‑2 by specifying the technical safety requirements to be observed in respect of the material properties of hydrogen and hydrogenated natural gas for the plants described in the preceding paragraph. It furthermore complements the requirements on pipelines specified in DVGW Codes of Practice G 462‑1, G 462‑2 and G 463 by describing the specific requirements in respect of hydrogen. Additionally, it explains how to handle hydrogen measurements during the course of injection.
G 402 Code of Practice 07/201171,30 €*
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 05/201771,30 €*
This code of practice represents the conceptual restructuring of the DVGW damage and incident statistics data registration procedure. Code of Practice G 410 details the criteria for data registration which form the basis of the new DVGW database. 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.
