This standard specifies the essential safety requirements for the design and construc-tion of thermoforming machines, for continuous sheet and single sheets, of all types. Significant hazards are listed in clause 4 and specific safety requirements and/or meas-ures are listed in clause 5.
A thermoforming machine may consist of one or more units linked together. This stan-dard covers the following units:
- continuous sheet unwind unit
- single sheet feed unit
- material intake
- conveying equipment
- heating unit
- preheating unit
- edge heating unit
- forming station
- finishing station
- stacking station
- discharge station
- residual sheet winding unit
- sheet cutting unit.
This standard does not apply to units mounted upstream or downstream of the thermo-forming machine and
- which have a separate control and/or
- are located separately and/or
- have their own material intake
This standard does not apply to units which are integrated into form, fill and seal ma-chines. These are covered in prEN 415-3:1996.
This standard does not apply to units which incorporate heating systems which are fu-elled by gas.
This standard applies to machines which are manufactured after the date of approval by CEN.
