Gas cylinders — Guidance for design of composite cylinders — Part 4: Cyclic fatigue of fibres and li...
This document addresses the topic of cyclic fatigue of structural reinforcing fibres as used in composite cylinders, and cyclic fatigue of structural and non-structural liners in these cylinders. This document provides a basic level of understanding of these topics.
Internet of Things (IoT) - Functional architecture for resource identifier interoperability
ISO/IEC 30181:2024 specifies functional requirements and architecture about the following items for resource interoperability among heterogeneous IoT platforms through the conversion of resource identifiers (IDs) and paths (e.g. uniform resource identifier (URI)):
– requirements for interoperability of resource IDs in the heterogeneous IoT platforms;
– functional architecture for converting IDs…
