Overview
EN 12267:2003+A1:2010 is a CEN (European) standard for food processing machinery - circular saw machines - safety and hygiene requirements. It specifies design and manufacturing requirements for circular saws used to cut bone and meat (saw blade diameter 350–400 mm). The standard covers two machine types: floor-type circular saws with a feed table and fixed product pusher (feed table height 800–1050 mm), and circular saws installed into cutting lines (conveyor or roller conveyor). It excludes domestic machines and saws for wood processing. EN 12267 applies to machines manufactured after its date of issue and includes Amendment 1 (2010).
Key topics and technical requirements
- Hazard identification: comprehensive list of mechanical, electrical, stability, noise, ergonomic and hygiene hazards specific to meat/bone cutting.
- Mechanical safety: guarding of saw blade zones, protective hoods, product pushers, interlocks and locking devices to prevent access to cutting zones.
- Electrical safety: safe electrical component specification and measures to prevent shock and malfunction; considerations for integration in cutting lines.
- Stability: requirements for wheel-mounted and floor-mounted machines to prevent tipping and crushing hazards.
- Noise control: noise test code (Annex A) and guidance for measurement and reduction to protect hearing.
- Ergonomics: design principles to minimize unhealthy postures and excessive physical effort during operation and maintenance.
- Hygiene and cleanability: principles and design guidance for cleanability (Annex B) to prevent microbial, chemical and physical contamination of food products.
- Verification & information: testing/verification procedures, required information for use, operator training and marking.
- Normative annexes: Annex C lists common hazards and reduction requirements; Annex ZA explains conformity with EU Machinery Directive (2006/42/EC).
Practical applications
- Use EN 12267 to design, manufacture, evaluate or procure circular saw machines for meat processing lines.
- Apply the standard during risk assessment, equipment acceptance, commissioning, and for maintenance and cleaning procedures.
- It helps ensure machines meet EU safety and food-hygiene expectations, reducing workplace injuries, contamination risk and regulatory non-compliance.
Who should use this standard
- Machine designers and manufacturers of meat/bone circular saws
- Food industry safety engineers and plant managers specifying equipment for cutting lines
- Procurement professionals and compliance officers assessing conformity with EU directives
- Maintenance, hygiene and training teams responsible for safe operation and cleaning
Related standards
EN 12267 references and works alongside standards such as EN ISO 12100, EN 60204-1, EN 1672-2, EN ISO 13849-1, EN ISO 4871 and relevant guarding and ergonomic standards for a complete safety and hygiene program.

In addition, they shall be designed according to the principles of !EN ISO 12100" for hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges). !For hazards which are to be reduced by the application of the type B-standards such as EN 614-1, EN 953,
EN 1005-3, EN 1088, EN 60204-1, EN 60529, EN ISO 12100, EN ISO 13849-1 and EN ISO 13857, the manufacturer shall carry out a risk assessment to establish the requirements of the type B-standard. This specific risk assessment shall be part of the general risk assessment of the machine." Where the means of reducing the risk is by the physical arrangement or positioning of the installed circular saw the manufacturer shall include in the Information for use a reference to the reduction means to be provided, and to any limiting value of the requirement, and, if appropriate, to the means of verification. Where the means of reducing the risk is by a safe system of working the saw, the manufacturer shall include in the information for use details of the system and of the elements of training required by the operating personnel. 5.2 Mechanical hazards 5.2.1 Circular saw machines with feed table and fixed product pusher 5.2.1.1 Protection of saw blade Zone 1 Access to the cutting zone on the saw blade shall be prevented. This can be achieved e.g. by the following measures: SIST EN 12267:2003+A1:2010
The interlocking system of the protective hood shall conform to the requirements described in 5.2.1.2. After actuation of the interlocking switch of the protective hood the blade should come to a standstill as soon as is possible, but the time taken shall not exceed 4 s.

Figure 6 — Protection bar Zone 3 Access to the saw blade below the feed table shall be prevented. This can be achieved e.g. by the following measures: A fixed protection bar or a closed machine casing shall be provided on the circumference of the saw blade (see Figure 6). The feed table may be foldable and interlocked. The chip pan or a chip removal flap shall be interlocked on machines without protection bar. The saw blade shall come to a standstill within 4 s after actuation of the interlocking switches. For requirements relating to the interlocking system of the feed table, chip pan and chip removal flap, see 5.2.1.2. SIST EN 12267:2003+A1:2010
mechanical damages, protect against the effects of cleaning and disinfection materials, protect against the effects of cleaning fluids (water), protect against defeating by simple methods, and comply with 5.7 of EN 1088:1995. In the instruction handbook, the manufacturer shall indicate the need for regular verification of the interlocking devices, and for the user to determine the frequency of verification depending upon the usage of the machine. 5.2.2 Circular saw machine in cutting line Zones 1 and 2 Access to the saw blade at the cutting zone and discharge side above the feed plane (transport device) shall be prevented. This can be achieved e.g. by the following measures: A guard (e.g. a protective hood) shall be provided on the feed and discharge side above the feed plane (transport device). When lifted, the protective hood may expose the cutting zone as well as the product discharge zone and shall automatically revert to its protective position by its own dead weight (see Figure 7). If the protective hood is removable, it shall be interlocked. The saw blade shall come to a standstill within 4 s after actuation of the interlocking switch of the protective hood. For requirements relating to the interlocking system of the removable protective hoods, see 5.2.1.2.

Circular saw machines intended for use in a cutting line shall be provided with a means to visually or audibly warn of it ceasing to function under the operation of a safety device, or, shall be fitted with a means capable of interrupting the electrical supply to other elements in the cutting line. Details shall be included in the Information for use. 5.3.3 Emergency stop-device !In general circular saw machines do not require an emergency stop device. Nevertheless, if the risk assessment to be carried out by the manufacturer results in the conclusion that such a device would reduce the stopping time, the machine shall be fitted with an emergency stop device. If no emergency stop device is fitted, the normal OFF switch shall be easily reachable from the operator position." 5.3.4 Protection against water ingress 5.3.4.1 IP degrees of protection Electrical operating components shall comply with the following degrees of protection in accordance with
