This document specifies the safety requirements for the design of must and grape harvest pumps and the means for verifying these requirements and gives information for the safe use of the machines covered.
This document applies to must and grape harvest pumps, as defined in 3.1, intended for the transfer of fresh, de-stemmed grapes and pomace.
This document deals with all significant hazards, hazardous situations or hazardous events relevant to grape harvest pumps, when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, specified in Annex B.
This document does not deal with hazardous phenomena associated with the integration of grape harvest pumps with other machinery.
This document does not give additional requirements for operations subject to special rules (e.g. explosive atmosphere, power supply from electrical networks where the voltage, frequency and tolerance differ from those of the public network).
This document is not applicable to:
— adaptations intended for other fruit harvests;
— pumps for building materials (covered by EN 12001 [1]);
— pumps on grape harvesters;
— reception conquests;
— machines upstream or downstream of the pump.
This document is not applicable to grape harvest pumps manufactured before the date of its publication.

This document gives the safety requirements and measures for stationary manually loaded and unloaded:
— cold presses,
— hot presses,
— bending presses,
— edge/face gluing presses,
— membrane presses,
— embossing presses,
where the pressing force is applied by hydraulic actuators pushing two flat or shaped surfaces against each other, hereinafter referred to as "machines".
It deals with all significant hazards, hazardous situations and events as listed in Clause 4 relevant to 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 are taken into account.
NOTE For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010.
It is also applicable to machines fitted with one or more of the following devices/additional working units, whose hazards have been dealt with:
a) Device for hot gluing
b) Device for high frequency gluing
c) Device for high frequency shaping
d) Automatic work-piece loading and unloading system
e) intermediate additional platens
f) work-piece extractor
g) work-piece clamping pressure beam
h) split moveable platens.
The machines are designed to process work-pieces consisting of:
1) solid wood;
2) materials with similar characteristics to wood (see ISO 19085-1:2017, 3.2);
3) honeycomb.

This document does not deal with any hazards related to:
i) specific devices that differ from the list above;
ii) hot fluid heating systems internal to the machine other than electrical;
iii) any hot fluid heating systems external to the machine;
iv) operation of taking intermediate platens out and in again;
v) the combination of a single machine being used with any other machine (as part of a line).
It is not applicable to:
— frame presses;
— membrane presses where the pressing force is applied by vacuum only;
— presses for producing chipboard, fibreboard, OSB;
— machines intended for use in potentially explosive atmosphere;
— machines manufactured before the date of its publication as an international standard.

This document specifies the safety requirements and measures for multi-blade rip sawing machines with manual loading and/or unloading (defined in 3.1) capable of continuous production use,
hereinafter referred to also as “machines”, designed to cut solid wood and materials with similar physical characteristics to wood.
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. Transport, assembly, dismantling, disabling and scrapping phases are also taken into account.
This document does not deal with specific hazards related to the combination of single machines with any other machine as part of a line.
It is not applicable to machines:
— with all saw blades spindles mounted below the workpiece support/level only (to include it, please provide requirements to DIS stage);
— intended for use in potentially explosive atmosphere;
— manufactured prior to its publication.

This document specifies the safety requirements and measures for manually loaded and unloaded
— single end tenoning machines with manual feed sliding table (defined in 3.1),
— single end tenoning machines with mechanical feed sliding table (defined in 3.2),
— single end tenoning and/or profiling machines with mechanical feed (defined in 3.3),
— double end tenoning and/or profiling machines with mechanical feed (defined in 3.4), also designed to be automatically loaded/unloaded,
— angular systems for tenoning and profiling with mechanical feed (defined in 3.5),
with maximum workpiece height capacity of 200 mm for single end machines and 500 mm for double end machines, capable of continuous production use, altogether referred to as “machines”.
It deals with all significant hazards, hazardous situations and events as listed in Annex A, relevant to 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.
The machines are designed to process in one pass one end or two sides, either opposite or perpendicular to each other, of workpieces made of:
1) solid wood;
2) materials with similar physical characteristics to wood (see ISO 19085 1:2021, 3.2);
3) fibre-cement, rock/glass wool, gypsum, plasterboard, only with machines with mechanical feed.
It is also applicable to machines fitted with one or more of the following devices/additional working units, whose hazards have been dealt with:
