General Information
- Abstract
This European Standard specifies safety and hygiene requirements for the design and manufacture of dough sheeters, as described in Clause 3, used in the food industry and craft activities (bread-making, pastry-making, sweet industries, bakeries, confectioners, delicatessens, catering facilities, etc.) for reducing the thickness of a solid mass of dough or pastry by rolling it out.
This European Standard deals with all significant hazards, hazardous situations and events relevant to the transport, installation, adjustment, operation, cleaning, maintenance, dismantling, disassembling and scrapping of dough mixers, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This European Standard deals with all significant hazards, hazardous situations and events relevant to dough sheeters, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 5).
Noise is not considered to be a significant hazard. This does not mean that the manufacturer is absolved from reducing noise and making a noise declaration. Therefore a noise test code is given in Annex B.
The following machines are excluded:
- experimental and testing machines under development by the manufacturer;
- dough sheeters where the dough is fed to the rollers by gravity (e.g. pizzabase dough sheeters);
- domestic appliances ).
This European Standard is not applicable to dough sheeters which are manufactured before the date of its publication as EN.

Overview
EN 1674:2015 (CEN) specifies safety and hygiene requirements for the design and manufacture of dough sheeters used in the food industry and craft activities (bakeries, pastry, confectionery, catering, delicatessens, etc.). It covers hazards and protective measures related to transport, installation, adjustment, operation, cleaning, maintenance, dismantling and scrapping of dough sheeters when used as intended or under reasonably foreseeable misuse. The standard excludes experimental/testing machines, gravity-fed dough sheeters (e.g. pizza-base sheeters) and domestic appliances. A noise test code is provided in Annex B although noise is not treated as a significant hazard.
Key topics and technical requirements
- Scope of application: machines that reduce dough thickness by rolling (manual or automatic gap adjustment).
- Risk coverage: identification and mitigation of all significant hazards (mechanical, electrical, hygiene and ergonomic) through design and protective measures.
- Mechanical hazards: controls for in‑running nip points (roller gaps), drive mechanisms (shearing, entanglement), conveyor infeed/outfeed pinch points, cutting/rolling attachments and removable flour-spreading devices (see mapped danger zones).
- Electrical safety: requirements on electrical equipment, protection against electric shock, earth-faults, motor enclosures and prevention of unexpected start-up.
- Hygiene & cleanability: materials, surface finish and design principles to ensure food-contact areas, splash areas and non-food areas can be cleaned effectively (Annex A outlines cleanability principles).
- Flour dust: requirements to limit flour dust emissions and related hazards (new in this edition).
- Verification & information: procedures for verifying compliance, required instruction handbook content and machine marking; noise declaration in accordance with Annex B where applicable.
Practical applications & who uses it
- Machine manufacturers: design and certify dough sheeters to meet EU safety and hygiene expectations.
- Food processors and bakeries: specify compliant equipment for production lines and craft operations.
- Safety engineers / CE conformity assessors: perform risk assessments, verification tests and conformity documentation aligned with EU Directive 2006/42/EC.
- Maintenance and cleaning staff: follow manufacturer instructions and hygiene design features to ensure safe operation and sanitary conditions.
- Procurement and compliance teams: evaluate and select equipment that meets EN 1674:2015 requirements.

In addition, the machine shall be designed according to the principles of EN ISO 12100:2010 for relevant, but not significant hazards, which are not dealt with by this document. Interlocking guards shall be at least interlocking without guard locking as defined in EN ISO 14119:2013, 4.1, and they shall comply with EN ISO 14119:2013, Clause 5 and 8.7.1. SIST EN 1674:2015

3b) Figure 3 — Guard dimensions The interlocking mechanism shall be housed within the machine body or otherwise protected to ensure that its operation is not adversely affected by for example dough or flour. Movable interlocking guards shall be free to move at their ends furthest from the rollers in order to act like a trip device if an operator attempts to reach under any guard. In case of openings inside the fixed or movable guard, the safety distances of the openings, e.g. carried out as bars or mesh, shall comply with EN ISO 13857:2008, Table 4. The safety distances shall be maintained for every position of the conveyor. The actuation of the interlocking device due to the lifting of the guard shall within one second — either cause the machine to stop. In this case restarting shall only be possible by intentionally actuating the starting control; — or it shall result in the reversal of the rotation of the rollers so that the operator cannot be drawn in, i.e. that the nip between the rollers is outrunning; when both guards are lifted, the machine shall stop. 5.2.1.2 Zone 2 The requirements for zone 1 shall be fulfilled. The maximum gap between the fixed support for the dough and the lower roller shall be

The actuation of the interlocking device due to the opening of the guard shall cause the machine to stop within one second. 5.2.1.4 Zone 5 Access to the in-running nip of the conveyors shall be prevented, e.g. by a guard such as the one marked “c” in Figure 5. The in-running nips shall be safeguarded by nip guards shaped as filling elements, filling bars or similar with a maximum gap of 4 mm both to the conveyor belt and the roller (see Figure 5).

If the force necessary to stop the moving parts of the flour duster is more than 150 N, the flour duster shall be protected by a fixed or interlocking guard. The flour container opening can be left unprotected if there is no risk from the flour feed system (e.g. if the feed consists of a spindle with rubber spokes or notches or if the flour is sprinkled by a vibrating device). 5.2.1.7 Zone 8 The requirements for zones 1, 2 and 3 shall be fulfilled.
