Holzbearbeitungsmaschinen - Sicherheit - Teil 5: Formatkreissägemaschinen (ISO/DIS 19085-5:2021)

Dieses Dokument beschreibt die Sicherheitsanforderungen für Formatkreissägemaschinen, wie in 3.1 definiert, die für den dauerhaften Einsatz in der Produktion geeignet sind und im Folgenden als „Maschinen“ bezeichnet werden.
Die Maschinen sind für das Schneiden von Massivholz und Werkstoffen mit ähnlichen physikalischen Eigenschaften wie Holz konstruiert.
Es behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse, wie sie in Anhang A aufgelistet sind, die auf die Maschinen zutreffen, wenn sie bestimmungsgemäß und entsprechend den vom Hersteller vorhergesehenen Bedingungen verwendet, eingestellt und gewartet werden; vernünftigerweise vorhersehbaren Fehlanwendungen wurden ebenso in Betracht gezogen. Ferner wurden die Phasen Transport, Montage, Demontage, Rückbau und Verschrottung berücksichtigt.
Es ist auch für Maschinen anwendbar, die mit einer oder mehreren der folgenden Baugruppen/zusätzlichen Arbeitsaggregaten ausgerüstet sind, deren Gefährdungen behandelt wurden:
a) Einrichtung zum Anheben und Absenken des Hauptsägeblattes und des Ritzsägeblattes;
b) Einrichtung zum Schrägstellen des Hauptsägeblattes und des Ritzsägeblattes für Winkelschnitte;
c) Einrichtung zum Ritzsägen;
d) Einrichtung zum Nuten mit einem Fräswerkzeug mit einer Breite von höchstens 20 mm;
e) abnehmbarer Vorschubapparat;
f) Aggregat zum Postforming-Schneiden;
g) kraftbetätigter Schiebetisch;
h) Werkstückspannvorrichtung.
Dieses Dokument gilt nicht für Maschinen, die zur Verwendung in potentiell explosiven Atmosphären vorgesehen sind, oder für Maschinen, die vor seinem Ausgabedatum hergestellt wurden.
