This document covers the development process for designers and developers of information for users of software. It describes how to establish what information users need, how to determine the way in which that information should be presented, and how to prepare the information and make it available. It is not limited to the design and development stage of the life cycle, but includes information…

This document specifies some gas compatibility test methods to evaluate plastic materials suitable for use in the manufacture of composite gas cylinder liners. It is also applicable to the evaluation of the suitability of plastic matrix materials used for Type 5 cylinders. Some fluids like water, used for cylinders testing, can react positively or negatively when in contact with plastic liners.…

IEC 61400-50-3:2022 describes procedures and methods that ensure that wind measurements using nacelle-mounted wind lidars are carried out and reported consistently and according to best practice. This document does not prescribe the purpose or use case of the wind measurements. However, as this document forms part of the IEC 61400 series of standards, it is anticipated that the wind measurements…

This document presents methods to establish technical interoperability between the contactless interfaces of NFC mobile devices and those of public transport readers and customer media. It provides information on how to apply these for public transport fare management systems which are using ISO/IEC 14443 and/or ISO/IEC 18092 and/or EMV® Contactless Interface Specification[1] [9] as a basis for…

1 Scope 1.1 General This Standard describes a method for the quantification of the aliphatic (R–OH), carboxylic acid (R–COOH), and phenolic (Ph–OH) hydroxyl groups present in lignin. Phenolic hydroxyl groups include a) syringyl (S), guaiacyl (G), and p-hydroxyphenyl (H) units; and b) condensed phenolics incorporating ß-5, 4-O-5’, and 5-5’ inter-unit linkages. 1.2 Methodology The procedure…

This test method is a standard procedure for the determination of paraffins, olefins, naphthenes, aromatics and unknowns (P.O.N.A.U.) in automotive gasolines using gas chromatography and flame ionization detection (GC/FID). Individual hydrocarbon components greater than or equal to 0.01 % by mass are determined. Group types greater than or equal to 0.01 % by mass are determined by summing…

1 Domaine d’application Le présent document donne des lignes directrices pour l’application du management de la qualité aux projets. Il s’applique aux organismes travaillant sur des projets de complexité variable, qu’ils soient petits ou grands, de courte ou de longue durée, individuels ou faisant partie d’un programme ou d’un portefeuille de projets, qui se situent dans des environnements…

This document defines the LIFE CYCLE requirements for development and maintenance of HEALTH SOFTWARE needed to support conformance to IEC 62443-4-1 – taking the specific needs for HEALTH SOFTWARE into account. The set of PROCESSES, ACTIVITIES, and TASKS described in this document establishes a common framework for secure HEALTH SOFTWARE LIFE CYCLE PROCESSES.The purpose is to increase the…

This document specifies the use of the integrated resources necessary for the scope and information requirements for modelling and simulation information in a collaborative systems engineering context (MoSSEC). The following are within the scope of this document: the representation of the collaborative understanding of the requirements and their verification; the representation of the elements…

IEC 62499:2021 gives rules for testing methods for newly manufactured pantographs contact strips. Not all tests may be relevant to some designs of contact strips. This document excludes tests using a particular pantograph. Additional supplementary tests, out of the scope of this document, may be necessary to determine suitability for a particular application and are by prior agreement between…
