Snow throwers - Safety requirements and test procedures - Part 2: Pedestrian-controlled snow throwers (ISO 8437-2:2019)

This document specifies safety requirements applicable to combustion engine powered pedestrian-controlled snow throwers. It is intended to be used with ISO 8437-1 and ISO 8437-4 to achieve the full requirements and means of verification for pedestrian-controlled snow throwers.
The ISO 8437 series deals with significant hazards, hazardous situations and events relevant to snow throwers used as intended and under the conditions reasonably foreseeable by the manufacturer.
It does not apply to the following:
—         electrically powered and battery powered snow throwers;
—         hand-held snow throwers;
—         airport or highway snow removal machines and equipment;
—         machines intended for use in potentially explosive atmospheres.
It does not deal with hazards related to the following:
—         battery circuits exceeding 42 V;
—         mains connected starting motor;
—         magneto grounding circuits;
—         working environment;
—         electromagnetic compatibility.
The ISO 8437 series is not applicable to machines that were manufactured before the date of its publication.

Dieses Dokument legt sicherheitstechnische Anforderungen fest, die auf verbrennungsmotorisch angetriebene handgeführte Schneefräsen anwendbar sind. Es ist zur Anwendung zusammen mit ISO 8437-1 und ISO 8437-4 vorgesehen, um die vollständigen Anforderungen und Prüfmittel für handgeführte Schneefräsen zu erreichen.
Die Normenreihe ISO 8437 behandelt die für Schneefräsen zutreffenden signifikanten Gefährdungen, Gefährdungssituationen und -ereignisse von Schneefräsen, die bestimmungsgemäß und unter den vom Hersteller vernünftigerweise vorhersehbaren Bedingungen der Fehlanwendung verwendet werden.
Sie gilt nicht für Folgende:
—   elektrisch angetriebene und batteriebetriebene Schneefräsen
—   handgehaltene Schneefräsen
—   Schneeräummaschinen und Geräte für Flughäfen oder Autobahnen
—   Maschinen zur Verwendung in explosionsgefährdeten Bereichen
Sie behandelt keine Gefährdungen in Bezug auf:
—   Batteriestromkreise, die 42 V überschreiten;
—   Stromnetze, die mit dem Anlasser verbunden werden;
—   Erdungsschaltkreise des Magnetzünders;
—   Arbeitsumgebungen;
—   elektromagnetische Verträglichkeit.
Die Normenreihe ISO 8437 gilt nicht für Maschinen, die vor dem Datum der Veröffentlichung hergestellt wurden.

Chasse-neige - Exigences de sécurité et essais - Partie 2: Chasse-neige à conducteur à pied (ISO 8437-2:2019)

Le présent document spécifie les exigences de sécurité qui s'appliquent aux chasse-neige à moteur à combustion à conducteur à pied. Il est destiné à être utilisé avec l'ISO 8437‑1 et l'ISO 8437‑4 afin de se conformer pleinement aux exigences et mettre en œuvre tous les moyens de vérification pour les chasse-neige à conducteur à pied.
La série ISO 8437 traite des phénomènes dangereux, des situations dangereuses et des événements dangereux significatifs applicables aux chasse-neige lorsqu'ils sont utilisés comme prévu et dans des conditions raisonnablement prévisibles par le fabricant.
Elle ne s'applique pas:
—          aux chasse-neige électriques et à batterie;
—          aux chasse-neige portatifs;
—          aux machines et au matériel de déneigement pour aéroports ou autoroutes;
—          aux machines destinées à être utilisées dans des atmosphères explosibles.
Elle ne traite pas des phénomènes dangereux associés:
—          aux circuits de batterie dépassant 42 V;
—          aux démarreurs raccordés à l'alimentation secteur;
—          aux circuits de mise à la masse de la magnéto;
—          à l'environnement de travail;
—          à la compatibilité électromagnétique.
La série ISO 8437 ne s'applique pas aux machines fabriquées avant sa date de publication.
