Overview - EN 1807-2:2013 (CEN)

EN 1807-2:2013 is the European harmonised safety standard for band sawing machines - Part 2: Log sawing machines, published by CEN to support compliance with the Machinery Directive (2006/42/EC). It covers stationary and displaceable log band sawing machines (manual or automatic loading/unloading) designed to cut solid wood, addressing all significant hazards and foreseeable misuse as described in Clause 4. The standard excludes table band saws/band re-saws (covered by EN 1807-1), machine combinations in production lines, specific automatic loading/unloading hazards, other machining processes, and thermal engine/PTO-specific hazards. Machines built before publication are not covered.

Key topics and technical requirements

EN 1807-2 defines practical safety measures and testing methods. Major topics include:

• Controls and control systems - safety and reliability requirements; mode selection; emergency stop; tracking; speed control. Performance Level requirements reference EN ISO 13849-1 (superseding older EN 954-1 categories).
• Protection against mechanical hazards - blade holder and blade design, prevention of access to moving parts, stability, risk of break-up, guard design and guard-locking (interlocks). Guard-locking of type N (EN 1088) is required when blade run-down ≤ 10 s and type M when > 10 s.
• Braking and run-down tests - test procedures and acceptance for unbraked and braked run-down times (Annex D).
• Emission controls - requirements for dust and chip containment and measurement; noise emission measurement procedures (Annex B).
• Non-mechanical hazards - fire, noise, electrical safety, ergonomics, hydraulics/pneumatics, vibration, electromagnetic compatibility, static electricity.
• Maintenance and information for use - marking, instruction handbook and operator information essential for safe operation.
• Normative test methods - impact tests for guards (Annex C) and guard adjustment tests (Annex A).

Practical applications - who uses EN 1807-2:2013

• Manufacturers and designers of log band sawing machines - to design machines that meet harmonised European safety requirements and enable CE marking.
• Safety engineers and compliance officers - to assess machine conformity with the Machinery Directive and manage risk assessments.
• Testing laboratories and certification bodies - to perform braking, noise, impact and guard tests described in the annexes.
• Purchasers and plant managers - to specify safer equipment, ensure installation meets guarding/control requirements, and support safe maintenance and operation.

5 Safety requirements and/or measures 5.1 General The machine shall comply with the safety requirements and/or protective measures of Clause 5. In addition, the machine should be designed according to the principles of EN ISO 12100:2010 for hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges of the machine frame). For guidance in connection with risk reduction by design, see EN ISO 12100:2010, 6.2, and for safeguarding measures, see EN ISO 12100:2010, 6.3. 5.2 Controls 5.2.1 Safety and reliability of control systems 5.2.1.1 General For the purpose of this document safety related part of a control system means the system from the initial device, e.g. actuator or position detector or sensor, up to and including the power control element of the final machine actuator, e.g. motor or brake. Safety related parts of the control system of this machine comprise parts concerning the following functions and they shall fulfil the requirements of the PL given in the clauses listed below, in accordance with the requirements of EN ISO 13849-1:2008:  Starting and restarting: PL = c (see 5.2.3);  normal stopping: PL = c (see 5.2.4);  emergency stop (if required): PL = c (see 5.2.5);  speed changing by belt position: PL = c (see 5.2.8);  speed monitoring: PL = c (see 5.2.8);  interlocking: PL = c (see 5.2.3, 5.2.8, 5.3.4, 5.3.7.1.2, 5.3.7.1.3.1,);  interlocking with guard locking: PL = c (see 5.2.8, 5.3.7.2);  mode selection (if required): PL = c (see 5.2.7);  opening/closing the adjustable saw blade guard during movement of the reciprocating carriage, moving head rig, conveyor feed or travelling table: PL = c (see 5.3.7.1.3);  braking function: PL = b or PL = c (see 5.3.4.1); SIST EN 1807-2:2013

a) be positioned at least 1,2 m from the cutting area as shown in Figure 5; or b) be separated from the cutting area by a deterring/impeding device which creates a reach distance of 1,2 m to the saw blade. NOTE This doesn't apply for machines equipped with a control cabin (see 5.4.5). Setting controls which are not required during the normal processing operation may be positioned within 1,2 m of the cutting area. Control devices shall not be located in the path of the reciprocating carriage, conveyor feed, moving head rig, travelling table, other handling equipment or logs. In all cases, the operator shall, from the normal operating position, be able to see (directly or by means of auxiliary device e.g. mirror, CCTV) the exposed part of the saw blade and the entire path of the reciprocating carriage or other relevant movement, unless the machine is located within perimeter fencing and the controls are sited in a separate control cabin.
Verification: By checking the relevant drawings and/or circuit diagrams, measurement, visual inspection of the machine and functional testing of the machine. SIST EN 1807-2:2013

1 1 200 mm to saw line Figure 5— Log saws - Danger area around the blade 5.2.3 Starting Before starting or restarting the machine all interlocked guard(s) (where fitted as indicated in 5.3.7) shall be in place and functional. This is achieved by the interlocking arrangements described in 5.3.7. For non interlocked guards provisions before starting, see 6.3, list entry c), sub-entry 6). Start or restart shall only be possible by actuation of the start control device provided for that purpose. For electrically operated machines the requirements of 9.2.5.2 of EN 60204-1:2006 apply but the exceptions described in 9.2.5.2 of EN 60204-1:2006 are not relevant. The drive motor for the driven band wheel shall only become operable after any interlocked guards are in place and functional. In the automatic cutting mode, the integrated feed shall not be capable to start before the band saw is running. In any other mode where the operator is close to the machine the band saw drive need not to be activated. NOTE
This can be achieved by means of a star delta start control device or a time delay device. The safety related part of the control systems (see also 5.2.1) for starting and for the interlocking arrangements as indicated in 5.3.7 shall be at least PL = c in accordance with the requirements of EN ISO 13849-1:2008
At log band saws under manual control the controls for integrated feed movement shall be of the 'hold-to-run' type unless the machine is located within an interlocked with guard locking perimeter fence. At log band saws under manual control the controls which operate the log turning devices shall be of the hold-to-run type unless the log turning device is enclosed in an interlocked with guard locking perimeter fence. The safety related part of the control systems (also see 5.2.1) for hold-to-run shall be at least PL = c in accordance with the requirements of EN ISO 13849-1:2008. SIST EN 1807-2:2013
