IEC 60269-3:2024 is divided into four fuse systems, each dealing with a specific example of standardized fuses for use by unskilled persons. This part applies to “gG” fuses only. Unskilled persons do not have technical knowledge or sufficient experience. To avoid dangers, which electricity may create, the relevant part of the fuse standard shall provide requirements for maximum safety in service…

IEC 63241-2-3:2024 supplements or modifies the corresponding clauses in IEC 63241-1, so as to convert it into the IEC Standard: Particular requirements for hand-held concrete grinders and disc-type sanders. Where a particular subclause of IEC 63241-1 is not mentioned in this document, that subclause applies as far as reasonable. Where this document states "addition", "modification…

Scope 1.1 These requirements cover alarm valves for use in automatic wet-pipe sprinkler systems for fire protection service. Alarm valves covered by these requirements are of either the variable- or constantpressure type and are of the swing-check pattern. Ordinarily, variable-pressure alarm valves are acceptable for constant-pressure service without alteration; however, in some designs, that…

Domaine d’application 1.1 Ces exigences couvrent les soupapes d’alarme utilisées dans les systèmes de gicleurs sous eau automatiques pour service de protection contre les incendies. Les soupapes d’alarme couvertes par ces exigences sont des clapets antiretour à battant pour type de pression constante ou variable. D’ordinaire, les soupapes d’alarme pour pression variable sont acceptables pour…

1 Scope 1.1 These requirements cover Original Equipment Manufacturer (OEM) and non-OEM crimp tools that have been evaluated for use with the following types of specified connecting devices: a) Grounding and bonding equipment; b) Electrical quick-connect terminals; c) Wire connectors; d) Wire-connector adapters; e) Ferrules; and f) Lightning protection components. These crimp tools are…

This document specifies principles for the design of agricultural machinery and tractors utilizing systems (perception, supervisory or other) to prevent unintended excursions beyond the boundary of the autonomous operating zone which are used in agricultural applications and that have partially automated, semi-autonomous and autonomous functions. Additionally, it provides guidance on the type of…

This document specifies principles for verification methods and validation principles of agricultural machinery and tractors that are used in agricultural applications and that have partially automated, semi-autonomous and autonomous functions. The purpose of this document is to assist in the provision of more specific safety requirements, means of verification and information for use to ensure…

This document specifies principles for the design of obstacle protective systems used in agricultural machinery and tractors that are used in agricultural applications and that have partially automated, semi-autonomous and autonomous functions. Additionally, it provides guidance on the type of information to be provided by the manufacturer on safe working practices (including information about…

This document specifies principles for the design of agricultural machinery and tractors that are used in agricultural applications and that have partially automated, semi-autonomous and autonomous functions. Additionally, it provides guidance on the type of information to be provided by the manufacturer on safe working practices (including information about residual risks). The purpose of this…

IEC 62463:2024 is applicable to security screening systems designed to expose persons to X‑rays. In particular, the document applies to systems where the body is exposed to the primary beam of X-rays. It is common to divide currently used systems into three types: backscatter systems, transmission systems and combination backscatter/transmission systems. The purpose of this document is to provide…
