L’IEC 60115-8:2023 s’applique aux résistances fixes pour montage en surface utilisées dans les équipements électroniques. Ces résistances sont généralement décrites selon des types (différentes formes géométriques), des modèles (différentes dimensions) et des technologies de produits. Ces résistances comportent des sorties métalliques et sont conçues principalement pour être montées directement…

IEC 62788-2-1:2023 specifies the safety requirements for flexible polymeric front- and backsheet constructions, which are intended for use as relied-upon insulation in photovoltaic (PV) modules. The specifications in this document define the specific requirements of polymeric front- or backsheet constructions on the component level and cover mechanical, electrical, visual and thermal…

IEC 62788-2-1:2023 spécifie les exigences de sécurité pour les constructions souples de faces avant et de faces arrière polymères, prévues pour être utilisées comme isolation attendue dans les modules photovoltaïques (PV). Les spécifications du présent document définissent les exigences spécifiques des constructions des faces avant ou arrière polymères au niveau des composants et couvrent la…

This document specifies the fundamental formulae for use in the tooth root stress calculation of straight and helical (skew), Zerol and spiral bevel gears including hypoid gears, with a minimum rim thickness under the root of 3,5 mmn. All load influences on tooth root stress are included, insofar as they are the result of load transmitted by the gearing and able to be evaluated quantitatively.…

This document specifies the methods of calculation of the load capacity of bevel gears, the formulae and symbols used for calculation, and the general factors influencing load conditions. The formulae in this document are intended to establish uniformly acceptable methods for calculating the load-carrying capacity of straight, helical (skew), spiral bevel, Zerol and hypoid gears. They are…

This document specifies a method for the determination of drag reduction of slick water, which is mainly used to evaluate the drag reduction performance of slick water. This document uses the pipeline method to evaluate the drag reduction, which is currently recognized as the best method to evaluate the drag reduction performance. This document describes the device, experimental conditions and…

This document defines visual aspects for the identification and assessment of product characteristics for friction materials in terms of quality and for commercial and technical agreements. The sequence of the product characteristics represents no order of priority. Inspection is carried out in unused, “as supplied” condition. In some characteristic features, there are differences between brake…

This document provides testing methods to evaluate the energy performance, emissions, safety and durability of institutional cookstoves. For general guidance (not a requirement), institutional cookstoves typically have firepower greater than 10 kW and/or cooking vessel volume greater than 25 l. The evaluation of household cookstoves is covered in ISO19867-1 and ISO19869 and is not addressed in…

This document is intended to be applied to the usage of predictive maintenance methods for the detection of degrading faults in safety related E/E hardware elements. It applies to hardware elements developed for compliance with the ISO 26262[1] series in which degrading faults are shown to be relevant due to, for instance, the technology used. Specific technical implementations of predictive…

This technical specification identifies and clarifies lighting properties for digital building design and maintenance. This document provides all the needed properties to design and to describe lighting systems. These properties are intended to be used for mapping between data providers and requesters. The mapping of the identifiers enables the exchange of luminaire and sensing device data within…
