Content of DVGW Code of Practice G 100 DVGW Code of Practice G 100 serves as a basis for assessing the competence of technical experts for inspecting the technical safety of energy systems for gas and hydrogen supply. It specifies qualification requirements for technical experts for energy systems for the pipeline-bound supply of gas and hydrogen to the general public. In the course of converting the gas infrastructure to hydrogen in accordance with DVGW Code of Practice G 260, technical experts have a special role to play. The qualification requirements described in this DVGW Code of Practice G 100 form the basis for the inspections to be carried out in this context. This includes, in particular,the continuous training of the technical experts in relation to the developing state of the art. G 100 describes the qualification requirements for technical experts who inspect and assess the technical safety of gas supply energy systems on the basis of the Energy Industry Act (Energiewirtschaftsgesetz - EnWG) in accordance with the requirements of GasHDrLtgV and the DVGW Set of Rules. The person commissioning the inspection is responsible for selecting a suitable technical expert for the inspection task in question. When commissioning a certified technical expert, the qualification for the relevant technical field can be verified by a valid certificate from a certification body accredited in accordance with GasHDrLtgV or official recognition in accordance with GasHDrLtgV. When commissioning an inspection body, the inspection body is responsible for selecting technical experts qualified for the respective inspection task. The technical expert is also responsible for checking whether his qualifications are sufficient for the inspection task. This Code of Practice G 100 can serve as a basis for this. DVGW Code of Practice G 100 ensures that the legal and technical framework conditions are mastered, only well-trained persons are recognised as technical experts, the technical experts have a practical connection to their area of specialisation, have sound knowledge and experience in the respective area of expertise, the specialised knowledge can be applied to specific issues in the subject area, the tasks, possibilities and discretionary scope of the technical experts can be recognised, used andfilled. The following amendments have been made compared to DVGW Code of Practice G 100:2015-10: The normative references have been adapted to the current status of the DVGW Set of Rules. The term energy facility was adapted due to the planned expansion of the term “Energy” to includehydrogen in the Energy Industry Act in order to clarify that this Code of Practice also applies to hydrogennetworks. The designation of Area of Expertise VIb has been adapted to the contents of the 2020 edition ofDVGW Code of Practice G 472. Notice has been included in the description of the areas of expertise that the technical experts inaccordance with this Code of Practice fulfil the qualification requirements for a person qualified toperform inspections in accordance with the German Industrial Safety and Health Ordinance(Betriebssicherheitsverordnung - BetrSichV) for testing the explosion safety of systems in their respectivearea of expertise. A corresponding explanation has been included in the foreword. In clauses 6.4.2.2, 6.4.2.3, 6.4.2.5 and 6.4.3.8, the term "explosion protection" has been replaced by"explosion safety" in order to establish the reference to the test object in accordance with IndustrialSafety and Health Ordinance (BetrSichV). For area of expertise IX, the required level of qualification was compared with the requirements of DINEN ISO 15257, which has replaced DIN EN 15257. In clause 6.5.1, references to the explosion safety testing for FG II, III, V and VIII have been added asa prerequisite for initial recognition. In Annex A, the listed Technical Rules have been adapted to the current status of Set of Rules andexpanded to include the technical rules on hydrogen systems.
