IEC 62841-3-3:2024

Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery - Safety - Part 3-3: Particular requirements for transportable planers and thicknessers

IEC 62841-3-3:2024 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 planers and thicknessers.
IEC 62841-1:2014, Clause 1 is applicable, except as follows:
This document applies to transportable planers, thicknessers and combined planers and thicknessers intended for cutting wood and analogous materials with a maximum planing width of 330 mm.
This document does not apply to planers, thicknessers or combined planers and thicknessers other than transportable.
NOTE 101 ISO 19085-7:2019 gives requirements for planers, thicknessers or combined planers and thicknessers other than transportable.

Outils électroportatifs à moteur, outils portables et machines pour jardins et pelouses - Sécurité - Partie 3-3: Exigences particulières pour les dégauchisseuses et les raboteuses portables

IEC 62841-3-3:2024 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 dégauchisseuses et les raboteuses portables.
Le présent document s'applique aux dégauchisseuses, aux raboteuses et aux dégauchisseuses-raboteuses portables destinées à couper du bois et des matériaux analogues avec une largeur maximale de dégauchissage de 330 mm.
Le présent document ne s'applique pas aux dégauchisseuses, aux raboteuses ou aux dégauchisseuses-raboteuses non portables.
NOTE 101 L'ISO 19085-7:2019 fournit les exigences applicables aux dégauchisseuses, aux raboteuses et aux dégauchisseuses-raboteuses non portables.
