Domestic gas cooking appliances — Safety — Part 1: General requirements
This document specifies the safety requirements for domestic gas cooking appliances. This covers appliances that are freestanding, built-in or table-top and are intended to be used indoors. This document applies to the gas sections of the appliances and their component parts (e.g. combined gas-electric cooking appliances). This document does not apply to: a) electrical heated elements as part of the appliance; b) outdoor appliances; c) appliances supplied at pressures greater than the maximum pressure of the test gases; d) cook stoves covered by the standards developed by ISO/TC 285. In general, it does not take into account children playing with the appliance. NOTE 1 For requirements regarding electrical safety, refer to the IEC 60335 series. NOTE 2 Attention is drawn to the fact that: — for appliances intended to be used in vehicles or on board of ships or aircrafts, additional requirements can apply; — in many countries, additional requirements are specified by the national health authorities, the national water supply authorities and similar authorities. This document does not cover requirements relating to gas cylinders, their pressure regulators and their connections. This document does not cover requirements for gas installation.
Appareils de cuisson domestiques utilisant les combustibles gazeux — Sécurité — Partie 1: Exigences générales
Le présent document spécifie les exigences de sécurité des appareils de cuisson domestiques utilisant les combustibles gazeux. Ces appareils sont isolés, encastrés ou à poser sur table et sont destinés à être utilisés en intérieur. Le présent document s'applique aux sections à gaz des appareils et à leurs éléments (par exemple, appareils de cuisson combinés utilisant l’électricité et les combustibles gazeux). La présente Norme internationale ne s'applique pas aux: a) éléments chauffés électriquement faisant partie de l’appareil; b) appareils utilisés en extérieur; c) appareils alimentés à des pressions supérieures à la pression maximale des gaz d’essai; d) fourneaux, couverts par les normes en cours d’élaboration par l’ISO/TC 285. Elle ne tient généralement pas compte d’enfants jouant avec l’appareil. NOTE 1 Pour les exigences relatives à la sécurité électrique, se référer à la série des normes IEC 60335. NOTE 2 L'attention est attirée sur le fait que: — pour les appareils destinés à une utilisation dans des véhicules ou à bord de bateaux ou aéronefs, des exigences supplémentaires peuvent être nécessaires; — dans de nombreux pays, des exigences supplémentaires sont spécifiées par les autorités sanitaires nationales, les services nationaux de distribution d’eau et les autorités similaires. Le présent document ne couvre pas les exigences relatives aux bouteilles à gaz, à leurs régulateurs de pression ou à leurs raccords. Le présent document ne couvre pas les exigences relatives à l’installation de gaz.
