This document specifies technical characteristics and strength requirements for fork arm extensions and telescopic fork arms for industrial trucks. It applies to fork arm extensions and telescopic fork arms, as defined in ISO 5053‑2, designed for use on industrial trucks and stacking lift trucks, as defined in ISO 5053‑1, having fork arm carriers and, in the case of fork arm extensions, fork arms…

Le présent document spécifie une méthode d’essai pour la détermination de la résistance à la rupture par traction, de l’allongement à la force maximale et de l’énergie absorbée à la rupture par traction du papier tissue et des produits tissue. Il utilise un appareil d’essai de traction fonctionnant à un gradient d’allongement constant. Il spécifie également la méthode de calcul de l’indice de…

This document provides an appropriate reference spectral irradiance distribution to be used in determining relative performance of solar thermal, photovoltaic, and other systems, components and materials where the direct or hemispherical irradiance component is desired. This document provides one reference hemispherical irradiance spectrum, one reference direct normal irradiance spectrum and 171…

This document specifies the equipment and procedures for determining the deviation from flatness for full-size products. It is applicable to thermal insulating products.

This document specifies a procedure for determining the lowest temperature at which rubber- or plastics-coated fabrics will not exhibit fractures or coating cracks when subjected to specific impact conditions. Rubber-or plastics-coated fabrics are used in many applications involving low-temperature flexing with or without impact. Data obtained by this method can be used to predict the behaviour…

This document specifies a test method for the determination of the tensile strength, stretch at maximum force and tensile energy absorption of tissue paper and tissue products. It uses a tensile-testing apparatus operating with a constant rate of elongation. It also specifies the method of calculating the tensile index and the tensile energy absorption index.

IEC 61753-089-02:2022 contains the minimum initial test and measurement requirements and severities which a fibre-optic pigtailed wide wavelength division multiplexing (WWDM) device for monitoring passive optical networks (PON) using an optical time-domain reflectometer (OTDR) satisfies in order to be categorised as meeting the requirements of category C (indoor controlled environment), as…

IEC 61753-089-02: 2022 contient les exigences minimales initiales d’essai et de mesure ainsi que les sévérités auxquelles satisfait un dispositif de multiplexage par répartition en longueur d'onde large (WWDM) fibronique équipé de fibres amorces destiné à la surveillance des réseaux optiques passifs (PON, Passive Optical Networks) au moyen d'un réflectomètre optique dans le domaine…

IEC 61196-1-124:2022 defines the test method to determine the coupling loss of radiating coaxial communication cables that are intended for use in wireless communication systems such as tunnels, railways, highways, subways, elevators and other confined areas in which conventional antenna transmission is not satisfactory or even impossible.
