This document specifies methods for determining the initial ring stiffness of glass-reinforced thermosetting plastics (GRP) pipes. Two methods are given (constant load and constant deflection), and within the specified deflection limits, each is equally valid and can be used for any diameter.

This document defines various parameters to be tested for the communication channel between two Ethernet devices (e.g. ECUs for automotive application) and also for the transmission media including cables and connectors as a single component of which the communication channel consists. This document also specifies the general RF requirements for a physical layer communication channel for ISO/IEC/…

This document specifies minimum requirements and test methods for the terrestrial part or leaves of Epimedium brevicornu Maxim., Epimedium sagittatum (Sieb.et Zucc.) Maxim., Epimedium pubescens Maxim. and Epimedium koreanum Nakai. which are derived from wild and cultivated Epimedium Herb. This document applies to Epimedium Herb that are sold and used as natural medicines in international trade,…

This document specifies requirements and test methods for materials and seams of re-usable and single use protective clothing providing protection of the wearer against infective biological agents. Design criteria, mechanical requirements, and functional fit requirements are basd on either ISO 16602 series or by the ISO 20384 as indicated in this document, while the barrier properties of this…

This document specifies the characteristics of hexagon socket countersunk head screws with reduced loadability due to head design, in steel and stainless steel, with metric coarse pitch threads M2 to M20, and with product grade A. NOTE 1 Other dimensional options are given in ISO 888, ISO 965-1 and ISO 4753. NOTE 2 The reduced loadability (related to the countersunk head dimensions in combination…

ISO/IEC 27000:2018 offre une vue d'ensemble des systèmes de management de la sécurité de l'information (SMSI). Il comprend également les termes et définitions d'usage courant dans la famille de normes du SMSI. Le présent document est applicable à tous les types et à toutes les tailles d'organismes (par exemple: les entreprises commerciales, les organismes publics, les…

This document describes approaches and provides guidance on processes for the verification and validation analysis of AI systems (comprising AI system components and the interaction of non-AI components with the AI system components) including formal methods, simulation and evaluation. This document is applicable for AI systems verification and validation in the context of the AI system life…

This document establishes the permissible operational parameters in terms of guide values for the calculation of selected multi-lobed and tilting-pad journal bearings. In order to attain a sufficient operational safety of multi-lobed and tilting-pad journal bearings by the calculation according to ISO/TS 31657-1, it is necessary for the operational characteristic value hmin to be significantly…

This document specifies the characteristic values for selected two-, three- and four-lobe bearings. The functions plotted and listed in table form below are required for the operationally safe design of hydrodynamic multi-lobed journal bearings according to ISO/TS 31657-1. They are based on the presumptions and boundary conditions indicated there and only apply to stationary operating states. The…

This document specifies a method for determining by extrapolation the long-term ultimate ring bending strain and the calculation of the long-term ultimate relative ring deflection of glass-reinforced thermosetting plastics (GRP) pipes, under wet conditions. Two methods of loading are given, one using plates the other beam bars.
