1.1 This document specifies safety and hygiene requirements for the design and manufacture of craft bakery and pastry depositors which:
a) are intended to be used:
— to deposit only pasty food (i.e.: cream, dough, batter etc.);
— to deposit only on trays;
— as standalone machines;
— with manual loading of the dough in the hopper;
b) are intended to be used with manual loading and unloading of the tray/s on/from the conveyor;
c) can carry out only the following movements and relevant directions (see Figure 1a)):
— Z: Vertical movement of the table and/or the deposit unit;
— X: Horizontal movement of the conveyor;
— Y: possible horizontal component of the movement only of the nozzles themselves inside the deposit unit;
d) are fitted with one or more hoppers whose capacity is ≤ 60 dm3 each; and
e) have a total length of the tray conveyor ≤ 1 600 mm;
f) have a vertical movement between nozzles and conveyor ≤ 200 mm;
g) have a maximum deposit performance:
— ≤ 60 cycles/minute with up/down movement of the table or the deposit unit;
— ≤ 100 cycles/minute without up/down movement of the table or the deposit unit;
h) have a maximum trays performance ≤ 4 trays/minute.
These machines are intended only for professional use.
NOTE The machine is provided for being used by one operator at a time.
The loading of the dough in the hopper can be done by means of a separate automatic loading system, but in that case the hazards arising from the use of the automatic hopper loading system are not covered by this document.
This document deals with all significant hazards, hazardous situations and events relevant to adjustment, operation and cleaning of craft bakery and pastry depositors, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
This document covers requirements for the safe operation of the machine, including loading, depositing, unloading, cleaning and maintenance.

1.2 The following hazards are not covered by this document:
— hazards arising from the use of an automatic hopper loading system;
— hazards due to packaging, handling or transport;
— hazards arising from electromagnetic compatibility issues;
— hazards due to dismantling and disassembling;
— hazards due to the noise emitted by the machine;
— hazards due to control devices;
— hazards due to operational stop;
— hazards due to selection of control or operating modes;
— hazards due to failure of the power supply;
— hazards due to surfaces, edges or angles;
— hazards due to combined machinery;
— hazards due to variations in operating conditions;
— hazards due to uncontrolled movements;
— hazards due to adjustable guards restricting access;
— hazards due to errors of fitting;
— hazards due to radiation;
— hazards due to laser radiation;
— hazards due to isolation of energy sources;
— hazards due to information and warnings on the machinery;
— hazards due to information and information devices.
The significant hazards covered by this document are described in Annex A.
1.3 The following machines are excluded from the scope of this document:
a) machines which deposit pasty food by means of needles (injection);
b) machines where the trays are put onto and/or removed from the conveyor automatically;
c) machines which require a blade for the cutting system;
d) domestic appliances;
e) machines for industrial production;
f) machines to deposit other products than food for bakery and pastry products.

1.4 In drafting this document, it has been assumed that the depositors falling within the scope are operated only by trained personnel. This document is not applicable to machines which are manufactured before the date of publication of this European Standard.

This document applies to the following groups of machines, auxiliary equipment and their combinations:
— palletizers;
— depalletizers;
— auxiliary equipment incorporated in or linked to the operations of palletizers and depalletizers;
— conveying system which are part of palletizers or depalletizers.
The individual machines are described in 3.2. Auxiliary equipment is described in 3.3.
For all packaging machines within the scope of this document, EN 415-10 also applies. EN 415-4 describes the additional or specific hazards for palletizers and depalletizers. The requirements of this document will take precedence over the requirements set out in EN 415-10.
This document deals with safety requirements for machine design, transport, installation, commissioning, operation, adjustment, maintenance and cleaning of palletizers, depalletizers, auxiliary equipment and conveying systems which are part of palletizer or depalletizer. The extent to which hazards, hazardous situations and events are covered are indicated in Clause 4.
NOTE The hazards on a specific machine can vary depending on its working principle, the type, size and mass of the product, the packaging material, auxiliary equipment attached to the machine and the environment in which the machine is used. If the machine presents hazards that are not covered by this document or EN 415-10, it is intended that the manufacturer will assess these hazards and take measures by using the principles detailed in EN ISO 12100.
Exclusions:
This document is not applicable to the following machines:
— machines where the layer is built manually on the pallet or pallet load without layer forming and layer transfer;
— machines that were manufactured before the date of publication of this document by CEN;
— conveyors that connect palletizers and depalletizers with machines that are not in the scope of this document.
Conveyors in the scope of this document also fall in the scope of EN 619.
This document describes the additional or specific hazards for conveyors fitted into palletizers and depalletizers and so the requirements of this document take precedence over the requirements of EN 619.
This document does not consider the following hazards:
— the use of palletizers and depalletizers in potentially explosive atmospheres;
— the health, safety or hygiene hazards associated with the products that are contained in the unit load handled by palletizers and depalletizers except with regard to possible malfunction of a machine causing spillage of hazardous substances.
