Content of DVGW G 102-5 Code of Practice G 102-5 serves as the basis for the qualification of qualified persons for pressure vessels. Certain qualified work may only be carried out by qualified persons. The qualified person shall acquire the necessary knowledge through theoretical training and practical instruction and experience. DVGW Code of Practice G 102-5 specifies the minimum requirements for the scope of the necessary personnel qualifications and the content of the corresponding training courses. Table of contentForeword 1 Scope 2 Normative references 3 Requirements for the qualification of qualified persons for the area of pressure vessels/pressure vessels under pressure 4 Implementation of the expert training 5 Contents of the expert training course 6 Success control 7 Technical requirements for instructors and inspectors Important normative references DVGW Code of Practice G 100DVGW Code of Practice G 495German versionDVGW-Arbeitsblatt G 102-5Buy DVGW G 102-5 Code of Practice You can purchase DVGW G 102-5 Code of Practice as PDF file for immediate download.

Content of DVGW Information GAS No. 29 This DVGW Information GAS No. 29 provides an overview of the requirements that must be met for the use of hydrogen in systems for the pipeline-bound supply of the general public and the connected gas applications so that these can be labelled "H2-ready".  In this DVGW Information GAS No. 29, a model is proposed to visualise the different levels of assessment in order to classify statements on the readiness of infrastructures for the grid-based supply of hydrogen. The term "H2-ready" is used to describe this readiness for hydrogen use, which is explained in the respective context in this DVGW Information GAS No. 29.  The proposed model can also be applied analogously to new or existing plants for operational self-supply in which hydrogen is to be used, taking into account the specific legal requirements.  Safe operation with the hazardous substance natural gas is already guaranteed for gas supply networks and gas applications. If a natural gas network is converted into a hydrogen network, the same level of safety can be guaranteed if the DVGW Codes of Practice applicable to hydrogen are taken into account - without prejudice to other legal requirements.

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.
