1 Scope 1.1 Inclusions This Standard specifies the test methods to be used in measuring the energy efficiency of small direct- current (dc), and single- and small three-phase alternating-current (ac) motors. It includes the following motor types: a) capacitor, permanent-split; b) capacitor, capacitor-start or capacitor-run; c) split phase; d) split phase start, capacitor-run; e)…

1 Scope 1.1 General This Standard applies to proponents making any change to a railway system that is technical, operational, or organizational in nature. The basic elements of the safety management system covered by this Standard include a) procedures for carrying out risk evaluation and analysis; and b) implementing risk control measures whenever a change in operating conditions or new…

This document specifies the mechanical and physical properties of nuts made of non-alloy steel or alloy steel, when tested at the ambient temperature range of 10 °C to 35 °C. This document applies to nuts: —    with ISO metric thread (see ISO 68-1), —    with diameter/pitch combinations according to ISO 261 and ISO 262, —    with coarse pitch thread M5 to M39, and fine pitch thread M8×1 to M39×3…

This document specifies requirements for the integration of numerical control systems (NC systems). It consists of technical and inspection requirements and test methods. This document is applicable to all machine tools using NC systems not already covered by class C standards (including metal cutting machine tools, metal forming machine tools and woodworking machine tools) and for partial…

IEC TS 62607-6-21:2022 establishes a standardized method to determine the chemical key control characteristics - elemental composition, and - C/O ratio for powders of graphene-based materials by - X-ray photoelectron spectroscopy (XPS). The elemental composition (species and relative abundance) is derived by the elemental binding energy and integral peak area at corresponding portion of XPS…

IEC 62819:2022 is applicable to eye, face and head protectors used in work where there is a risk of exposure to an electric arc hazard. Such protectors consist of one or several devices (e.g. hood, goggles, balaclavas, face shields, helmets, etc.), which might need to be combined together in order to give protection to eye, face and head for the intended use. This document covers the performance…

The requirements in this document apply to all toys, i.e. any product designed or clearly intended for use in play by children under 14 years of age. They are applicable to a toy as it is initially received by the consumer and, in addition, they apply after a toy is subjected to reasonably foreseeable conditions of normal use and abuse unless specifically noted otherwise. The requirements of this…

IEC 63299:2022 specifies classification rules for metallic magnetic powder cores used in inductive components fulfilling the requirements of the electronics industries. This document addresses the following objectives for magnetic powder cores suppliers and users: - cross-reference between core materials from multiple suppliers; - assistance to users in understanding the published technical…
