Food processing machinery - Band saw machines - Safety and hygiene requirements

1.1   General
This European Standard specifies requirements for the design and manufacturing of band saw machines as described in 1.2 (see Figures 1 to 5).
The machines covered by this European Standard are used to cut:
-   bones;
-   fresh or deep frozen meat with or without bones ;
-   fresh or deep frozen fish, natural or in fillets ;
-   deep frozen block food products;
-   fresh or deep frozen vegetables;
-   other products such as pork fat or similar products.
The band saw machines covered by this European Standard do not include band saw machines for processing wood and similar materials which are covered by the EN 1807 series.
Band saw machines for domestic use are not included in this European Standard.
This document is not applicable to band saw machines which were manufactured before its date of publication as EN.
This European Standard deals with all significant hazards, hazardous situations and events relevant to band saw machines, 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 all the lifetime of the machine, including the phases of transport, assembly, commissioning, operation, cleaning, use, maintenance, decommissioning, dismantling, disabling and scrapping of the machine.
This European Standard covers the following types of machines:
-   band saw machines designed as table-top machines with and without base;
-   band saw machines designed as floor-type machines with and without castors.
1.2   Description of various machine types
1.2.1   General
Band saw machines consist of a machine casing, a fixed feed table or a sliding feed table, a roller conveyor or conveyor belt, a product pusher, a height-adjustable protective rail, a top and a bottom wheel, a saw blade, an upper and lower blade guide, a blade tensioning device, a drive and electrical components, depending on machine type. This standard does not deal with machinery with automatic loading/unloading systems (e.g. automatic conveyors).
On floor-type band saw machines, the product to be cut is placed by hand onto the fixed feed table or sliding feed table and pushed against the cutting zone of the saw blade by means of the product pusher or the rear table wall on the sliding feed table or by means of the roller conveyor or conveyor belt and sawed.

Band saw machine with a fixed feed table, a protective rail and a maximum cutting height < 420 mm.
1.2.4   Type C
Band saw machine with a sliding feed table, a protective rail and a maximum cutting height ≤ 420 mm.
(...)
1.2.5   Type D
Band saw machine with non-automatic feed and removal unit (e.g. roller conveyor, conveyor belt); maximum cutting height SH ≤ 550 mm.

Overview

EN 12268:2014 - "Food processing machinery - Band saw machines - Safety and hygiene requirements" is a CEN (European) standard that specifies design, manufacturing and safety/hygiene requirements for commercial band saw machines used in the food industry. It covers table-top and floor-type band saw machines used to cut bones, fresh or deep-frozen meat and fish, frozen block products, vegetables and similar food products. The standard excludes machines for wood processing, domestic band saws and machines manufactured before its publication. EN 12268:2014 addresses hazards across the machine life‑cycle, including transport, assembly, operation, cleaning, maintenance and scrapping.

Key Topics

• Scope and machine types: Defines Types A–D (e.g., Type A: fixed feed table with non‑detachable pusher, SH ≤ 250 mm; Type B: fixed table/protective rail, SH < 420 mm; Type C: sliding feed table, SH ≤ 420 mm; Type D: non‑automatic feed/removal units, SH ≤ 550 mm).
• Hazard zones and mechanical safety: Requirements by danger zones (saw blade outside cutting zone, cutting zone protection, wheel areas, sliding feed table, drive system).
• Electrical safety: ON/OFF switching, stopping functions, protection against water ingress, electromagnetic considerations.
• Hygiene and cleanability: Design principles and materials to ensure food‑area cleanability, splash and non‑food area requirements, surface finish and cleaning procedures.
• Ergonomics and noise: Ergonomic design principles and noise reduction measures; Annex A provides a noise test code.
• Verification and documentation: Test and verification procedures, marking and instruction handbook requirements (including operator training).
• Annexes: Noise test code, cleanability design guidance, examples of work‑aid tools, and informative relationship to EU Machinery Directive 2006/42/EC (Annex ZA).

Applications and Who Uses It

EN 12268:2014 is used by:

• Manufacturers and machine designers to design compliant band saw machines for the food sector.
• Safety engineers and compliance officers for conformity assessment against EU Directive 2006/42/EC.
• Food processors and plant managers selecting equipment that meets hygiene and safety expectations.
• Maintenance teams and trainers to develop safe work procedures and operator instructions.
• Notified bodies and auditors verifying conformity and performing risk assessments.

Practical benefits include reduced contamination risk, improved operator safety, clearer maintenance and cleaning practices, and documented conformity for market access in Europe.

Related Standards

• EN ISO 12100 (machine risk assessment and safety principles)
• EN 614‑1 and EN 1005 series (ergonomics and human factors)
• Relevant EN electrical and EMC standards and national adaptations of EN 12268:2014 (implemented by CEN members)

Keywords: EN 12268:2014, band saw machines, food processing machinery, safety and hygiene requirements, CEN standard, cleanability, hazard zones, noise emission, machine design.
