1.1 General The original scope from N17 (NWI CEN/CLC TR Hyperloop systems - Standards inventory and roadmap) reads as follows: This document lists the relevant standards from various fields and provides a standardization roadmap for hyperloop systems. The roadmap will provide guidance on the applicable standards from various fields, those that need amending and the new-to be developed standards. 1.2 Methodology The WG has listed the relevant documents (standards, directives, etc) from various fields in order to provide a baseline for a standardization roadmap for hyperloop systems. The resulting document hence enhances the scope as it provides guidance on the applicable relevant documents from various fields that the working group has identified, analysed and proposed for an application in the hyperloop field. The following document is a first inventory that identifies those standards that the WG considers fully applicable, those deemed useful with certain adaptations for an application in hyperloop (or serving as an input for new, specific hyperloop standards to be created), and those that the WG considers not directly applicable for Hyperloop purposes. In addition, this document identifies relevant regulations, directives and related documents as well as some potential areas where new hyperloop standards will be needed. It needs to be stated that the WG has done its best endeavour to identify the (partial) reusability for hyperloop based on the available information (high-level descriptions of the standards, tables of contents, summary documents etc). In a next step, a roadmap will provide some guidance regarding those areas and point at new-to be developed standards for which a need has been identified. The yet-to-be-created roadmap will also sketch out the concrete steps to be taken w.r.t. to the development of the necessary Hyperloop standards. Moreover, an alignment with the other WIs will be performed, as it is important that all WIs are aligned and use the same language.
