Le présent document spécifie les principes et les méthodes pour l'estimation de l'endurance thermique des caoutchoucs d'après les résultats d'une exposition à des températures élevées pendant de longues périodes. Deux méthodes sont spécifiées (voir l'introduction): —    l'une utilisant l'équation d'Arrhenius; —    l'autre utilisant l'équation de…

This document establishes requirements and test procedures for determining the performance of spark arrestor exhaust systems of multi position small engines used in portable applications, such as chain-saws, brush-cutters, grass-trimmers, pole-mounted pruners, edgers and similar shaft-drive machines, hedge trimmers and hand-held and back-pack blowers. It is not applicable to spark arrestors used…

This document provides a consolidated set of rules and associated guidelines as found and defined in the existing parts of the ISO/IEC 15944 series. NOTE      Not all parts of the ISO/IEC 15944 series have rules, that is ISO/IEC 15944-6, ISO/IEC 15944-14 and ISO/IEC 15944-20.

Le présent document établit les exigences et les méthodes d'essai permettant de déterminer les performances des systèmes d'échappement avec pare-étincelles des petits moteurs multi-positions utilisés dans des applications portatives, comme les scies à chaîne, les débroussailleuses, les coupe-herbe, les élagueuses montées sur perches, les coupe-bordures et autres machines similaires…

This document specifies two methods for the determination of co-monomer contents of polyethylene products by solution state 13C-NMR spectrometry (nuclear magnetic resonance spectrometry): —    method A: inverse gated decoupling method. —    method B: insensitive nuclei enhanced by polarization transfer method; This document is applicable to copolymers of ethylene having a content of other 1-…

This document shows the results of investigating the guideline for determining the threshold of the evaluation result on an electric inertial chassis dynamometer that electrically controls the amount of inertia using fuel consumption. This document is applicable when the running resistance force of a chassis dynamometer is set in accordance with ISO 18580.

This document specifies the physical, chemical and microbiological requirements for, and test methods of, starch acetates.

This document is intended to be applied to the usage of ISO 26262 methodology for rechargeable energy storage systems (RESS), for example, lithium-ion battery systems, that are installed in series-production road vehicles, excluding mopeds. This document does not address unique E/E systems in special vehicles such as E/E systems designed for drivers with disabilities. This document provides: a…

This document specifies the calculation procedures to calculate and assess a given bearing design, as well as to design a bearing as a function of some optional parameters. This document contains the design of the required lubrication system including the calculation of the restrictor data. This document applies to hydrostatic plain journal bearings under steady-state conditions.
