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.

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.
