Building construction machinery and equipment - Portable, hand-held, internal-combustion-engine-driven abrasive cutting machines - Part 1: Safety requirements for cut-off machines for centre-mounted rotating abrasive wheels (ISO 19432-1:2020)

EN-ISO 19432-1 specifies safety requirements and measures for their verification for the design and construction of portable, hand-held, internal combustion engine-driven cut-off machines intended to be used by a single operator in the cutting of construction materials, such as asphalt, concrete, stone and metal. It is applicable only to those machines designed purposely for use with a rotating, bonded-abrasive and/or super-abrasive (for example diamond) cut-off wheel having a maximum outer diameter of 430 mm, centre-mounted on and driven by a spindle shaft where the top of the wheel rotates away from the operator (see Figure 1).This document deals with all significant hazards, hazardous situations or hazardous events significant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. See Annex F for a list of significant hazards.This document specifies methods for the elimination or reduction of hazards arising from their use, as well as the type of information on safe working practices to be provided with the machines.Cut-off wheel specifications are not considered in this document. Cut-off wheels are deemed to comply to existing cut-off wheel standards.All through the document, portable, hand-held, internal combustion engine-driven cut-off machines are called “cut-off machines”.This document is not applicable to machines manufactured before the date of its publication.

Baumaschinen und -ausrüstungen - Tragbare, handgeführte Trennschleifmaschinen mit Verbrennungsmotor - Teil 1: Sicherheitsanforderungen für Trennschleifmaschinen mit um die Antriebsachse rotierender Trennschleifscheibe (ISO 19432-1:2020)

Dieses Dokument legt Sicherheitsanforderungen und Maßnahmen für die Prüfung der konstruktiven Gestaltung und des konstruktiven Aufbaus von tragbaren, handgeführten Trennschleifmaschinen mit eingebautem Verbrennungsmotor für den Einmannbetrieb fest, die zum Schneiden von Baumaterialien, wie z. B. Asphalt, Beton, Stein und Metall, bestimmt sind. Es gilt nur für solche Trennschleifmaschinen, die bestimmungsgemäß für den Einsatz mit einer rotierenden Trennschleifscheibe mit einem maximalen Außendurchmesser von 430 mm und mit Trennschleifkörpern aus gebundenen Schleifmitteln und/oder Schleifwerkzeugen (zum Beispiel mit Diamantschleifmitteln) vorgesehen sind, die mittig auf einer Spindelwelle montiert sind und von dieser angetrieben werden, wobei sich die Stirnseite der Trennschleifscheibe in einer vom Bediener abgewandten Richtung dreht (siehe Bild 1).
Dieses Dokument behandelt alle signifikanten Gefährdungen, Gefährdungssituationen oder Gefährdungsereignisse, die auf diese Maschinen zutreffen, wenn sie bestimmungsgemäß und unter den vernünftigerweise vom Hersteller vorhersehbaren Bedingungen des Missbrauchs verwendet werden. (Siehe Anhang F für eine Liste der signifikanten Gefährdungen.)
Dieses Dokument legt Verfahren für die Beseitigung oder Verminderung von Gefährdungen, die sich aus deren Anwendung ergeben, sowie die Art von Informationen über sichere Arbeitspraktiken fest, die mit der Maschine bereitzustellen sind.
Spezifikationen für Trennschleifscheiben werden in diesem Dokument nicht behandelt. Es wird davon ausgegangen, dass Trennschleifscheiben die geltenden Normen für Trennschleifscheiben erfüllen.
ANMERKUNG   Beispiel siehe Literaturhinweise.
In diesem Dokument werden tragbare, handgeführte Trennschleifmaschinen mit eingebautem Verbrennungsmotor generell als „Trennschleifmaschinen“ bezeichnet.
Dieses Dokument gilt nicht für Maschinen, die vor dem Veröffentlichungsdatum dieses Dokuments hergestellt wurden.

Machines et matériels pour la construction des bâtiments - Machines de coupe par abrasion, portatives, à moteur à combustion interne - Partie 1: Exigences de sécurité des tronçonneuses à disque abrasif monté au centre (ISO 19432-1:2020)

Le présent document spécifie les exigences de sécurité et les mesures de vérification, pour la conception et la fabrication de tronçonneuses à disque, portatives, à moteur à combustion interne, conçues pour être utilisées par un seul opérateur, pour couper des matériaux de construction, tels que l'asphalte, le béton, les pierres et le métal. Le présent document s'applique uniquement aux tronçonneuses spécifiquement conçues pour l'utilisation de meules à tronçonner, composées de particules abrasives agglomérées et/ou de particules super-abrasives (par exemple diamant), d'un diamètre extérieur maximal de 430 mm, qui présentent un montage central sur un arbre, sont entraînées par cet arbre et dont la partie supérieure tourne loin de l'opérateur (voir Figure 1).
Le présent document traite de tous les phénomènes, situations et événements dangereux significatifs spécifiques de ces machines lorsque celles-ci sont utilisées dans les conditions prévues et dans des conditions d'utilisation abusive relativement prévisibles par le constructeur. Voir Annexe F pour la liste des phénomènes dangereux significatifs.
Le présent document spécifie les méthodes d'élimination ou de réduction des phénomènes dangereux résultant de leur utilisation ainsi que les informations relatives aux recommandations d'utilisation à fournir avec la machine.
Les spécifications de la meule à tronçonner ne sont pas prises en considération dans le présent document. Les meules à tronçonner sont considérées conformes aux normes de meule à tronçonner en vigueur.
NOTE       Par exemple, voir la Bibliographie.
Dans le document, les machines de coupure à moteur à combustion interne portatives, sont appelées «machines de coupure» portatives.
Le présent document ne s'applique pas aux machines fabriquées avant la date de publication du présent document.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
