1 Scope This document is a specialization of the more general reference model for software and systems product line engineering and management described in ISO/IEC 26550. The specialization defined herein addresses a class of methods and tools referred to as feature-based software and systems product line engineering, or feature-based PLE, which has emerged as a proven and repeatable product…

This document states the minimum requirements, recommendations, permissions and possibilities for ensuring interoperable web services from an accessing party’s perspective. The document: —    states requirements on the structure and format of resources; —    defines the concept of resource identifiers (direct and correlated); —    provides different resource categories (e.g. anonymous,…

IEC 63182-4:2021 specifies the preferred range of the dimensions that are of importance for mechanical interchangeability and gives guidelines on allowable limits of surface irregularities for block-cores made of metallic magnetic powder. This document is a specification about surface irregularities which is useful in the negotiations between suppliers and users of magnetic powder-cores.

IEC 63182-5:2021 specifies the preferred range of the dimensions that are of importance for mechanical interchangeability and gives the guidelines on allowable limits of surface irregularities for cylinder-cores made of metallic magnetic powder. This document is a specification useful in the negotiations between magnetic powder core suppliers and users about surface irregularities.

This document specifies a classification and designation system for a selection of the most common unfilled thermoplastic polymers for plain bearings. The unfilled thermoplastic polymers are classified on the basis of appropriate levels of distinctive properties, additives and information about their application for plain bearings. The designation system does not include all properties;…

This document specifies requirements for the exchange of messages that contain master data consisting of characteristic data. These requirements can be checked by computer. The messages are suitable for exchange between organizations and between systems. EXAMPLE 1     A supplier sends a message to a customer. The message contains characteristic data describing an item that the customer is…

This document describes methods for checking laser profilometer performance with respect to the capability of such equipment in measuring pavement texture. The objective of this document is to make available an internationally accepted procedure by which performance of various laser-based equipment for pavement texture measurements can be evaluated. The document includes guidelines and…

IEC TS 62607-6-10:2021(E) establishes a standardized method to determine the electrical key control characteristic – sheet resistance (Rs) for films of graphene-based materials by – terahertz time domain spectroscopy (THz-TDS). In this technique, a THz pulse is sent to the graphene-based material. The transmitted or reflected THz waveform is measured in the time domain and transformed to the…

Le présent document définit les propriétés qui caractérisent le couplage des ondes lumineuses à l’entrée et la sortie de circuits optiques intégrés (IOC) et de circuits avec circuits photoniques intégrés (PIC). Le présent document se concentre sur le couplage en about par l’intermédiaire des faces des guides d’ondes. Les définitions fournissent la base de spécification des éléments à coupler (par…
