1 Domaine d’application 1.1 Installations et lieux de travail touchés Cette norme détermine les exigences relatives à un système de GSO pour les installations et lieux de travail traitant ou entreposant des matières potentiellement dangereuses, soit en raison d’une propriété chimique, biologique, toxicologique ou physique intrinsèque de ces matières, ou en raison de l’énergie cinétique ou…

L'IEC 60793-1-31:2024 décrit trois méthodes pour déterminer et mesurer la largeur de bande modale des fibres optiques multimodales (voir l’IEC 60793-2-10, l’IEC 60793-2-30 et l’IEC 60793‑2‑40). La réponse en fréquence de bande de base est directement mesurée dans le domaine fréquentiel en déterminant la réponse de la fibre à une source de lumière modulée de manière sinusoïdale. La réponse en…

This document provides the guidelines, minimum requirements and performance characteristics intended to guarantee that manufactured systems intended for on-site/field use (i.e. outside the laboratory) provide reliable and reproducible results. This document specifies the requirements for technologies that enable on-site detection and quantification of Legionella spp. and L. pneumophila using a…

1 Scope 1.1 General This Standard specifies requirements for workplace electrical safety necessary for the practical safeguarding of workers during activities such as the installation, removal, inspection, operation, maintenance, and demolition of electric conductors and electric equipment, as well as work in proximity of energized electrical equipment. 1.2 Application While it can be…

This document specifies requirements and recommendations for the construction of buildings and other structures which provide accommodation for data centres based on the criteria and classification for “physical security” within ISO/IEC 22237-1 in support of availability. This document specifies requirements and recommendations for the following: a)       location and site selection (taking in to…

Scope 1.1 General This Standard applies to structural antennas, towers, antenna-supporting structures, and roof- and wall-mounted structures including their components, such as guys and foundations. It covers the structural design, fabrication, and erection of new structures and the modification of existing structures. 1.2 Exclusions This Standard is not intended to apply to a) attachment…

This document specifies an engineering method for calculating the attenuation of sound during propagation outdoors in order to predict the levels of environmental noise at a distance from a variety of sources. The method predicts the equivalent continuous A-weighted sound pressure level (as described in ISO 1996-series) under meteorological conditions favourable to propagation from sources of…

Scope 1.1 This Standard sets forth the minimum requirements for containment sumps, and associated sump fittings and accessories (products) intended for below-grade, or at-grade, or above-grade use as an enclosure for the housing of, and access to, underground piping, connector piping, and other fueling system components (such as pumps, valves, sensors, wiring, etc.), in addition to temporary…

Scope 1.1 This Standard sets forth the minimum requirements for cover primary, secondary, and coaxial types of flexible connector pipes intended for short length transfer and containment of the specific flammable and combustible liquids (or vapors thereof) identified in this Standard, at commercial (public) or fleet (private) automotive motor vehicle fueling stations or similar fuel…
