Plastics and rubber machines - Thermoforming machines - Safety requirements

This European Standard deals with all significant hazards, hazardous situations and events relevant to thermoforming machines for continuous sheet and single sheets of thermoplastics materials, when they are used as intended and under conditions of misuse which are foreseeable by the manufacturer (see Clause 4).
A thermoforming machine may consist of a forming unit or a forming unit linked to one or more additional units. This standard covers the following units:
-   continuous sheet unwind unit;
-   single sheet feed unit;
-   material intake;
-   conveying equipment;
-   heating unit;
-   preheating unit;
-   edge heating unit;
-   component feeding/inserting unit;
-   forming station;
-   finishing station;
-   stacking station;
-   discharge station;
-   residual sheet winding unit;
-   sheet cutting unit.
This European standard does not apply to units mounted upstream or downstream of the thermoforming machine:
-   which have a separate control system; and/or
-   are located separately.
NOTE 1   This European Standard specifies requirements for machines supplied as a single forming unit or a number of units designed to operate as a single machine. Additional units that may be introduced at a later stage should be considered separately applying relevant standards and taking into account any hazards arising through their interaction with the thermoforming machine.
This European Standard does not apply to units which are integrated into form, fill and seal machines. These are covered in EN 415-3:1999.
This European standard does not apply to units which incorporate heating systems which are fuelled by gas.
NOTE 2   Thermoforming machines generally do not create explosive atmospheres. In principle they therefore correspond with line F of Table 2 of the ATEX Guideline and consequently do not fall within the scope of Directive 94/9/EC.
This European Standard is not applicable to thermoforming machines which are manufactured before the date of its publication as EN.

⎯ Restfolienwickeleinrichtung;
⎯ Folienschneideinrichtung.
Diese Europäische Norm gilt nicht für Baugruppen, die der Warmformmaschine vor- oder nachgeschaltet sind,
und die
⎯ ein eigenes Steuerungssystem haben und/oder
⎯ separat angeordnet sind.
ANMERKUNG 1 Diese Europäische Norm legt die Anforderungen für Maschinen fest, die als Einzelformstation geliefert
werden oder die aus einer Vielzahl einzelner Stationen konzipiert sind und wie eine Einzelmaschine betrieben werden.
Weitere Baugruppen, die in einem späteren Stadium einbezogen werden, sollten unter Beachtung der relevanten Normen
und unter Berücksichtigung jeglicher Gefährdungen, die sich aus dem Zusammenwirken mit der Warmformmaschine
ergeben, gesondert betrachtet werden.
Diese Europäische Norm gilt nicht für Baugruppen, die in Form-, Füll- und Verschließmaschinen integriert sind.
Diese sind in EN 415-3:1999 behandelt.
Diese Europäische Norm gilt nicht für Baugruppen, die Heizungssysteme enthalten, die mit Gas betrieben
werden.
ANMERKUNG 2 Warmformmaschinen erzeugen grundsätzlich keine explosionsfähige Atmosphären. Sie stimmen
daher prinzipiell mit dem ATEX-Leitfaden, Tabelle 2, F, überein und fallen demzufolge nicht unter den
Anwendungsbereich der Richtlinie 94/9/EG.
Diese Europäische Norm gilt nicht für Warmformmaschinen, die vor der Veröffentlichung dieser EN hergestellt
worden sind.

Overview

EN 12409:2008+A1:2011 - published by CEN - is the European safety standard for thermoforming machines used with continuous sheet or single sheets of thermoplastic materials. It addresses all significant hazards, hazardous situations and events relevant to thermoforming machines when used as intended or under foreseeable misuse. The standard applies to a single forming unit or a combination of forming and auxiliary units designed to operate as one machine, and it includes Amendment 1 (2011).

Covered units include:

• continuous sheet unwind and residual winding units
• single sheet feed and material intake
• conveying, heating, preheating and edge-heating units
• component feeding/inserting, forming, finishing, stacking and discharge stations
• sheet cutting units

Not covered: units with separate control systems or located separately, units integrated into form–fill–seal machines (EN 415-3), and heating systems fuelled by gas.

Key Topics

EN 12409 is a Type C machine-specific safety standard (per EN ISO 12100) and takes precedence over Type A/B standards for machines designed accordingly. Major technical topics and requirements include:

• Risk identification and list of significant hazards: mechanical, electrical, pneumatic, hydraulic, control failures, energy-supply failures.
• Hazard specifics for each unit: e.g., unwind, feed, heating, forming, finishing, stacking, cutting.
• Protective measures and safety requirements: guarding, access control to danger zones, emergency precautions, safe setting and maintenance modes, prevention of unexpected start-up.
• Special risks: hot surfaces, inhalation of dusts/fumes/gases, noise, ergonomics, laser devices, manual handling.
• Verification and validation of safety measures and machine conformity.
• Information for use: marking, instruction manuals, safety labels, noise declarations, cleaning, maintenance and inspection guidance.
• Annexes provide typical machine layouts and an informative link (Annex ZA) to the Essential Requirements of the EU Machinery Directive 2006/42/EC.

Applications and Users

This standard is essential for:

• Machine manufacturers and designers developing thermoforming machines or subsystems.
• Safety engineers and compliance officers conducting risk assessments and CE conformity activities.
• System integrators and machine builders combining forming units with finishing or feeding units.
• Test labs, notified bodies and certification agencies verifying compliance.
• Plant managers and purchasers specifying safety requirements for new equipment.

Practically, EN 12409 guides safe machine design, protective guarding, control/lockout strategies, operator instructions, and documentation needed to meet European machinery safety requirements.

Related Standards

• EN ISO 12100 (general risk assessment and principles)
• EN 415-3 (form–fill–seal machines - excluded here)
• EU Machinery Directive 2006/42/EC (see Annex ZA)
• ATEX guidance (note: thermoforming machines generally fall outside Directive 94/9/EC per the standard)

Keywords: EN 12409:2008+A1:2011, thermoforming machines, safety requirements, plastics and rubber machines, CEN standard, machine safety, risk assessment.
