This document specifies a test method to measure the contact angle for the determination of the surface free energy of a solid surface. The method can be applied for the characterization of substrates and coatings. NOTE 1    For the determination of the surface free energy of polymers and coatings, it is preferred to use either the method according to Owens, Wendt, Rabel and Kaelble or the method…

This document specifies the required characteristics of repositories used for the long-term storage of archive and library materials. It covers the siting, construction and renovation of the storage facility, and the installation and equipment to be used both within and around the building. This document applies to all archive and library materials held in repositories, where mixed media can be…

This document specifies two procedures for the in situ determination of the insertion loss of underwater noise abatement measures (noise abatement systems). The impulsive sound of pile driving is used as the sound source for the investigation of noise abatement systems. This document does not apply to artificial sound sources and investigations under laboratory conditions. Apart from the correct…

This document specifies a test method to evaluate the effects of liquid cleaners and disinfectants on the properties of waterproof coated textiles that are used as the protective outer surface of assistive products for tissue integrity (APTIs). The test method is not applicable to outer surfaces of APTIs that are not sufficiently drapeable. The test addresses degradation by pure chemical contact…

Le présent document spécifie une méthode d’essai permettant de mesurer l’angle de contact afin de déterminer l’énergie libre de surface d’une surface solide. Cette méthode peut être utilisée pour la caractérisation de subjectiles et revêtements. NOTE 1        La détermination de l’énergie libre de surface de polymères et de revêtements se fait de préférence conformément à la méthode d’Owens,…

Le présent document spécifie une méthode d’essai permettant de mesurer la tension de surface des liquides à l’aide d’une méthode optique utilisant une goutte pendante. Cette méthode peut être utilisée pour la caractérisation des produits de peinture liquides. En cas d’application à des liquides à comportement d’écoulement non newtonien (tel que défini dans l’ISO 3219-1:2021, 3.22), des…

This document specifies principles and requirements for the definition, identification, optimization and harmonization of community infrastructure performance metrics. It provides recommendations for the analysis of community infrastructure, including availability, interoperability, synergy, resilience, safety, security and sustainability. Community infrastructure includes, but is not limited to…

This document specifies a test method to measure the surface tension of liquids with an optical method using the pendant drop. The method can be applied for the characterization of liquid coating materials. If applied to liquids with non-Newtonian flow behaviour (as defined in ISO 3219-1:2021, 3.22), restrictions can apply. NOTE       For other methods to determine the surface tension, see e.g.…

This document provides guidance to community authorities on how to use smart technologies and smart ways of working to improve their ability to anticipate, manage and mitigate public-health emergencies (PHEs), including through transparent, interactive and citizen-centric communications with citizens. It does this by demonstrating how the principles and good practices for smart city operating…

This document specifies requirements and recommendations for the core competences taught in training programmes in community interpreting. This document also identifies the core competences of educators who deliver training programmes in community interpreting. This document is applicable to signed languages and spoken languages, and addresses consecutive interpreting and simultaneous…
