Standards Development

Scope

This document specifies the safety requirements and measures for wide belt sanding machines (defined in 3.1) and for surface treating machines (defined in 3.2) capable of continuous production use, altogether referred to as “machines”.

This document deals with all significant hazards, hazardous situations or hazardous events, listed in Annex A, relevant to the machines when used as intended and under conditions of misuse which are reasonably foreseeable, as well as when transported, assembled, adjusted, maintened, dismantling, disabled and scrapped.

The machines are designed to process workpieces with flat surface and even thickness, in shape of panels or beams or frames, consisting of:

— solid wood;

— material with similar physical characteristics to wood (see ISO 19085-1:2021, 3.2);

— gypsum boards, gypsum bounded fibreboards;

— composite materials with core consisting of, e.g. polyurethane or mineral material;

— rock wool and glass wool;

— polymer-matrix composite materials and reinforced thermoplastic, thermoset and elastomeric materials;

— expanded polystyrene (EPS) or extruded polystyrene (XPS);

— graphite;

— carbon fiber;

— matrix engineered mineral boards, silicate boards;

— composite boards made from the materials listed above;

— all materials listed above, already lacquered.

This document is also applicable to machines fitted with one or more of the following devices or 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;

— multi blade unit;

— conveyor directly controlled by the machine;

— additional workpiece vacuum clamping device

— laser surface treating unit;

— antistatic bar unit.

NOTE 1 An antistatic bar is a device that eliminates electrostatic charges on the workpiece to ease its subsequent cleaning from dust by airflow.

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 700 mm;

— systems for powered loading or unloading, or both, of the workpiece to or from a single machine;

NOTE 2 Loading the machine manually includes manually placing the workpiece onto a conveyor directly controlled by the machine. Unloading the machine manually includes manually removing the workpiece from a conveyor directly controlled by the machine.

— out-feed workpieces on machines with feed speed higher than 60 m/min;

— interfacing of the machine with any other machine.

This document is not applicable to machines intended for use in a potentially explosive atmosphere and to machines manufactured prior to the date of its publication.
