BS EN 1114-1:2011

Plastics and rubber machines. Extruders and extrusion lines. Safety requirements for extruders (British Standard)

This European Standard specifies all significant hazards, hazardous situations and events relevant to all types of screw extruders for plastics and rubber, when they are used as intended and under conditions of misuse which are foreseeable by the manufacturer (see Clause 4). This European Standard additionally covers the following feeding systems: - hoppers; - single roller feed; - double roller feed; - crammer feeder; and the following ancillary equipment which form part of or are attached to the extruder: - screen changers; - melt/gear pumps; - melt pipes and adaptors; - static mixers; - extruder head that give initial shape to the extruded material. NOTE Metering devices are not covered by this standard. This European Standard does not deal with hazards caused by the processing of materials and which may lead to a risk of fire or release of health hazardous materials. An extruder conforming to this document is not regarded as a pressure vessel as defined in the Pressure Equipment Directive 97/23/EC. Extruders usually do not produce explosive atmospheres. Where materials are processed, which may cause an explosive atmosphere, the Directive 94/9/EC on the Equipment intended for use in Potentially Explosive Atmospheres (ATEX) should be applied. Explosion hazards are not dealt with in this document. This European Standard is not applicable to extruders which are manufactured before the date of its publication as EN.

Only the significant hazards listed in Clause 4 and dealt with in Clause 5 are subject to this European Standard. This European Standard does not deal with hazards caused by processing materials (such as Expanded Polystyrene (EPS) and Polyurethane (PU) foam) which, when heated, may lead to a risk of fire and release of toxic gases. This European Standard does not deal with hazards caused by upstream and/or downstream equipment. This European Standard is not applicable to agglomerators manufactured before the date of its approval as EN.



BS EN 12301:2000+A1:2008

Plastics and rubber machines. Calenders. Safety requirements (British Standard)

This European standard specifies safety requirements relating to the design and construction of multi-roll calenders intended for the processing of rubber or plastics.

BS EN 12409:2008+A1:2011

Plastics and rubber machines. Thermoforming machines. Safety requirements (British Standard)

This European Standard deals with all significant hazards, hazardous situations and events relevant to thermoforming machines for continuous sheets 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.


BS EN 13418:2013

Plastics and rubber machines. Winding machines for film or sheet. Safety requirements (British Standard)

This European Standard deals with all significant hazards, hazardous situations and events relevant to the design and construction of winding machines used for the winding and/or unwinding and/or rewinding and/or slitting of film or sheet manufactured from rubber, plastic and composite materials, when the machines are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). A machine used for winding or rewinding (winder or rewinder) begins at the intake of the film or sheet into the winding machine and ends at the discharge position of the reel(s). A machine used for unwinding (unwind) begins at the take-up position of the reel(s) and ends at the film or sheet take-off point. A machine used for unwinding, slitting and re-winding (slitter rewinder) begins at the take-up position of the reel(s) and ends at the discharge positions of the reel(s) and covers one or more integrated slitting/cutting units. In some machines the winding, unwinding, rewinding and slitting functions may be combined. Hazards due to electro-magnetic radiation, e.g. from the use of thickness monitoring devices, are not covered by this European Standard. Toxic or chemical hazards and hazards due to dusts, fumes or gases, which could occur from the materials being wound, unwound, slit or rewound are not covered by this European Standard. NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC. This European Standard is not applicable to winding machines which are manufactured before the date of its publication.

Plastics and rubber machines. Film converting machines for bags and sacks. Safety requirements (British Standard)

This European Standard specifies the safety requirements applicable to the design and construction of film converting machines for making bags and sacks, for the significant and specific hazards listed in Clause 4. This type of machine is based on the welding process. A film converting machine for bags and sacks starts at the film unwinding unit or at the film inlet when this machine is directly fed by an upstream process and ends at the product collection or delivery unit. The bag making line may include: 1) unwind units 2) slit-welding units 3) gussetting units 4) lane deviation units 5) perforating and welding or cutting and welding units 6) blocking units 7) pick-up and transfer units 8) stacking units 9) punching units 10) folding units 11) winding units 12) labelling or taping units 13) handle and closure units 14) draw tape insertion units 15) generators of electrostatic charge 16) electrostatic discharge equipment.

Ultrasonic radiation hazards resulting from ultrasonic welding devices, e.g. integrated in handle and closure units, are not covered by this standard. Film converting machines for bags and sacks 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 document is not applicable to machines which are manufactured before the date of its publication as EN.
