This document gives the safety requirements and measures for wide belt calibrating and sanding machines capable of continuous production use as defined in 3.1, hereinafter referred to as “machines”. It deals with all significant hazards, hazardous situations and events as listed in Annex A, relevant to the machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer, including reasonably foreseeable misuse. Also, transport, assembly, dismantling, disabling and scrapping phases have been taken into account. It is also applicable to machines fitted with one or more of the following devices/additional working units, whose hazards have been dealt with: — transversal sanding unit; — cleaning brushing unit; — satining roller unit; — disk brushing unit; — texturing brushing roller unit; — texturing brushing belt unit; — cutterblock unit; — texturing band saw unit; — spiked roller unit; — antistatic bars unit; — conveyor directly controlled by the machine; — additional work piece vacuum clamping device. NOTE 1 antistatic bar is a device that eliminates electrostatic charges on the workpiece to ease its subsequent cleaning from dust by airflow. The machines are designed to calibrate and/or sand workpieces, in shape of panels or beams, consisting of: a) solid wood; b) material with similar physical characteristics to wood (see ISO 19085-1:2021, 3.2); c) gypsum boards, gypsum bounded fibreboards; d) composite materials with core consisting of e.g. polyurethane or mineral material; Licensed to: Yassine, Ylva Ms Downloaded: 2021-07-21 Single user license only, copying and networking prohibited 1 © ISO 2021 – All rights reserved ISO/DIS 19085-8:2021(E) e) composite boards made from the materials listed above; f) all materials listed above, also already lacquered. This document does not deal with hazards related to: — specific devices other than those listed above; — access through in-feed and out-feed openings of machines with a work piece height capacity greater than 550 mm; — systems for powered loading and/or unloading of the work piece to/from a single machine; NOTE 2 Loading the machine manually includes manually placing the work piece onto a conveyor directly controlled by the machine. Unloading the machine manually includes manually removing the work piece from a conveyor directly controlled by the machine. — interfacing of the machine with any other machine. It is not applicable to machines intended for use in potentially explosive atmosphere and to machines manufactured prior to the date of its publication.
