General Information
- Abstract
1.1 This European Standard specifies the safety and hygiene requirements for the design and manufacture of food processors and blenders.
It applies to food processors and blenders having a bowl which is stationary while the food is being processed.
The total volume of the bowl is less than or equal to 150 l.
The machines covered by this standard are intended to carry out various types of operations such as: mincing, mixing, blending, whipping, using a large number of products and raw materials, and which are used in food and catering industries such as restaurants, hotels, coffee shops and pubs.
This European Standard specifies all significant hazards, hazardous situations and events relevant to food processors and blenders, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This European Standard deals with the hazards which can arise during commissioning, operation, cleaning, removal of food blockages, feeding, changing the tools, maintenance and decommissioning of the machine.
1.2 This standard does not apply to:
- domestic machines;
- machinery dedicated to food industrial processing (e.g. pet food, cannery industry, industrial meat processing).
Small machines called "shakers" which are dedicated to blending liquid, with an impellor, usually driven from above are excluded.
1.3 This European Standard is not applicable to food processors and blenders which are manufactured before the date of its publication as EN.

Overview
EN 12852:2001+A1:2010 is a CEN Type C standard that specifies safety and hygiene requirements for commercial food processors and blenders with a stationary bowl and a total bowl volume ≤ 150 L. Prepared by CEN/TC 153, the standard covers significant hazards arising during commissioning, operation, cleaning, removal of blockages, feeding, tool changes, maintenance and decommissioning. It supports conformity with the EU Machinery Directive (2006/42/EC) and is intended for foodservice and catering equipment used in restaurants, hotels, coffee shops, pubs and similar commercial kitchens.
Key topics and technical requirements
- Scope and machine types: Applies to machines with stationary bowls; defines machine types by total volume and power (e.g., type 1: Vt < 5 L; type 2: 5–25 L and P ≤ 3 kW; type 3: 25–150 L or P > 3 kW). Excludes domestic machines, heavy industrial processing machinery and small “shakers.”
- Hazard identification: Lists significant hazards - mechanical (zones 1–5: access to moving tools, drive shafts, tilting mechanisms, ejection of blades), electrical, hygiene, ergonomics and noise.
- Safety measures: Requirements for guards and interlocks, conformity with interlocking and guarding standards, stability, correct assembly, safe handling and storage of cutting tools, and specifications for controls and ergonomics.
- Hygiene and cleanability: Design principles to prevent food contamination, allow effective cleaning and reduce microbial and chemical residues (Annex B).
- Noise and verification: Noise test code and measurement/verification procedures are included (Annex A).
- Documentation & marking: Requirements for instruction handbooks, markings and user information to ensure safe use and maintenance.
- Risk assessment: Manufacturers must apply EN ISO 12100 principles and reference applicable type-B standards when relevant.
Practical applications and users
Who uses EN 12852:
- Manufacturers and machine designers - to design and certify safe, hygienic food processors and blenders for commercial use.
- Safety and compliance engineers - for risk assessments, CE conformity and machine validation.
- Procurement and facility managers - to specify compliant equipment for commercial kitchens and catering operations.
- Test labs and inspectors - to verify noise, guarding, electrical safety and cleanability.
Practical benefits: improved operator safety, reduced contamination risk, easier cleaning and maintenance, and demonstrable compliance with EU safety and hygiene regulations.

With completely removable covers, the interlock shall comply with EN 1088 (i.e. there shall be two interlock switches one operating in a positive mode and the other one in a negative mode). Where the application of this principle of positive mechanical action is not easily reconcilable with the other requirements for this kind of machine, e.g. hygiene, index of protection (IP), prevention of defeat and safety distances, the absence of a positive mechanical action of the cover on the position detector shall be balanced/compensated so as to achieve an equal level of safety e.g. by applying the principle illustrated in informative annex C. Nevertheless in all cases where a single mechanically actuated position detector is used, it shall comply with 6.2.1.2 of EN 1088:1995. !The safety distances from the upper edge of the aperture to the upper blade of the tool shall comply with
Table 4 and 4.2.4.3 of EN ISO 13857:2008." The stopping time shall be less than 4 s when the machine is running empty. If the bowl is removable, an interlocking device shall prevent the machine from starting with bowl incorrectly fitted. 5.2.1.3 Zone 3 !Access to the danger zone shall be prevented by a fixed guard complying with 5.3.2.2 of
EN ISO 12100-2:2003 and EN 953." Those requirements are applicable to the three types. 5.2.1.4 Zone 4 The bowl shall be tilted only by a voluntary action of the operator. The requirements shall be the same when the bowl is tilted back to its working position. When the tilting is power operated, the movement of the machine shall be controlled with a hold to run control situated out of the danger zone. The bowl shall remain stable in all positions when it stops. SIST EN 12852:2002+A1:2010

In case of single phase machines, no such device is required for the earthed neutral conductor. 5.3.5 Protection against earth faults in control circuits For machinery supplied from a single-phase conductor and an earthed neutral conductor, there is no requirement for double pole interruption of the control circuit. The single pole interruption shall be in the phase conductor (see 9.4.3.1 of EN 60204-1:2006). 5.3.6 Emergency stop Machines shall be fitted with at least one emergency stop (see 10.7 of EN 60204-1:2006), as far as the risk assessment carried out by the manufacturer doesn't allow to establish that such a device would not reduce the stopping time, or would not enable the special measures, required to deal with the risk, to be taken. In general no emergency stop is required for food processors and blenders. In this case particular attention shall be given to the accessibility of the normal OFF switch from the operator position. 5.3.7 Motor enclosures Where a motor has a degree of protection lower than IP23 it shall be mounted inside an enclosure (see 14.2 of
