IEC 62841-3-11:2024

Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 3-11: Particular requirements for transportable combined mitre and bench saws

IEC 62841-3-11:2024 applies to transportable combined mitre and bench saws intended to be used with a toothed saw blade for cutting wood and analogous materials, plastics and nonferrous metals except magnesium with a saw blade diameter not exceeding 315 mm, which hereinafter is simply referred to as saw or tool.
This document does not apply to:
- saws intended to cut other metals, such as magnesium, steel and iron, or food;
- saws with an automatic feeding device;
- saws designed for use with abrasive wheels;
- saws designed for use with dado blades;
- single function bench or table saws;
- single function mitre saws;
- combined mitre and bench saws other than transportable.
NOTE 101 Transportable saws intended to cut ferrous metals will be covered by a future part of IEC 62841-3.
NOTE 102 Transportable tools designed for use with abrasive wheels are covered by IEC 62841-3-10:2015.
NOTE 103 Transportable table saws are covered by IEC 62841-3-1:2014.
NOTE 104 Transportable mitre saws are covered by IEC 62841-3-9:2020.
NOTE 105 In Europe (EN IEC 62841-3-11), the following additional NOTE applies:
NOTE Z101 Combined mitre and bench saws other than transportable are covered by EN 1870-3:2014.
This document is to be used in conjunction with IEC 62841-1:2014. This document supplements or modifies the corresponding clauses in IEC 62841-1, so as to convert it into the IEC Standard: Particular requirements for transportable combined mitre and bench saws.

Outils électroportatifs à moteur, outils portables et machines pour jardin et pelouses - Sécurité - Partie 3-11 : Exigences particulières pour les scies circulaires combinées à onglet et à table transportables

IEC 62841-3-11:2024 s'applique aux scies circulaires combinées à onglet et à table transportables destinées à être utilisées avec une lame de scie dentée de diamètre inférieur ou égal à 315 mm conçue pour la coupe de bois et de matériaux analogues, de plastiques et de métaux non ferreux, à l'exception du magnésium, et ci-après simplement appelées scie ou outil.
Le présent document ne s'applique pas:
- aux scies conçues pour couper d'autres métaux, comme le magnésium, l'acier et le fer, ou de la nourriture;
- aux scies qui comportent un dispositif d'alimentation automatique;
- aux scies conçues pour être utilisées avec des meules abrasives;
- aux scies conçues pour être utilisées avec des lames à rainurer;
- aux scies à table monofonction;
- aux scies à onglet monofonction;
- aux scies circulaires combinées à onglet et à table autres que transportables.
NOTE 101 Les scies transportables destinées à couper des métaux ferreux seront traitées dans une future partie de l'IEC 62841-3.
NOTE 102 Les outils portables conçus pour être utilisés avec une meule abrasive sont traités dans l'IEC 62841‑3‑10:2015.
NOTE 103 Les scies circulaires à table transportables sont traitées dans l'IEC 62841-3-1:2014.
NOTE 104 Les scies à onglet transportables sont traitées dans l'IEC 62841-3-9:2020.
NOTE 105 En Europe (EN IEC 62841-3-11), la NOTE supplémentaire suivante s'applique:
NOTE Z101 Les scies circulaires combinées à onglet et à table autres que transportables sont traitées dans l'EN 1870-3:2014.
Le présent document doit être utilisé conjointement avec l'IEC 62841-1:2014. Le présent document complète ou modifie les articles correspondants de l'IEC 62841-1 de façon à la transformer en norme IEC: Exigences particulières pour les scies circulaires combinées à onglet et à table transportables.
