G 1010 Code of Practice 06/2023

Content of DVGW Code of Practice G 1010

This document DVGW Code of Practice G 1010 contains requirements for the qualification and organisation of operators of gas systems on factory premises, that are connected to the public gas supply (customer systems for internal company supply in accordance with Section 3 No. 24b EnWG). They include gas systems in the area of industrial gas use up to the last shut-off device before the gas is used.

Up to and including the last shut-off device upstream of the consumption system, these systems fall within the scope of the Energy Industry Act (§ 3, No. 15 EnWG). The DVGW Set of Rules therefore apply to these systems.

This worksheet applies to gas systems, that are operated with gases of the 2nd and 5th gas family in accordance with DVGW Code of Practice G 260.

If the gas systems are operated with natural gas-hydrogen mixtures of the 2nd gas family or with hydrogen of the 5th gas family, the guidelines for H2 readiness infrastructure, DVGW Guideline G 221, and gas application, DVGW Guideline G 655, must be observed in addition to the worksheets listed above. Annex A contains an informative overview.

For gases that do not comply with the provisions of DVGW Code of Practice G 260, this technical rule may be applied mutatis mutandis, considering the specific properties of the gases (e.g. metallurgical gases, landfill gases) and any other existing provisions.

For gases of the 3rd gas family according to DVGW Code of Practice G 260 (liquified petroleum gas), reference is made to DVGW G Code of Practice 1040 or TRF / DGUV Rule 110-010 and BetrSichV for the collective supply of liquid petroleum gas.

For biogas plants, reference is made to DVGW Code of Practice G 1030.

The aim of this Code of Practice G 1010 is to create a basis for safe supply - this includes the construction and safe operation of the gas pipeline system in accordance with the Energy Industry Act. By complying with the requirements of the DVGW regulations in this area, the points to be observed in the BetrSichV and DGUV Information 203-092 are also considerd.

If it is a closed distribution network in accordance with § 110 EnWG (supply to third parties), DVGW Code of Practice G 1000 shall be considered.

Industrial gas applications and directly associated system components are subject to the safety requirements of the relevant EG regulations and EG directives, which are described in the law on technical work equipment and consumer products (Product Safety Act - ProdSG and its subordinate regulations, e.g. Gas Appliances Regulation, 9th ProdSV and 14th ProdSV or subsequently harmonised DIN EN standards) and in particular in the Ordinance on Industrial Safety and Health (BetrSichV).
