1 Scope This document specifies the essential safety requirements for hydraulic presses, including toggle and hydro-mechanic ones, with a vertical closing movement more than 6 mm for the moulding of plastics and/or rubber. This document covers both compression moulding (see 3.1.1) and transfer moulding (see 3.1.2). All hazards listed in clause 4 are covered by this document. The following machines are excluded:  injection moulding machines (see EN 201);  presses for curing pneumatic tyres;  presses for curing inner tubes and curing bags;  hydraulic presses as covered by EN 693;  mechanical presses as covered by EN 692;  thermoforming machines (see EN 12409);  RIM machines (see EN 1612-1 and EN 1612-2). The safety requirements for the additional hazards arising from the interaction between presses and ancillary equipment especially loading and unloading devices are specified. The safety requirements for the ancillary equipment itself are not specified. This document does not cover:  the requirements of Directive 94/9/CE concerning equipment and protective systems intended for use in potentially explosive atmospheres;  requirements for the design of exhaust ventilation systems. This document is not applicable to presses manufactured before the date of publication of this document by CEN. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

3.1.1 compression moulding process in which the moulding material is placed into the open mould. When the press is closed, the moulding process is carried out under the influence of pressure with or without heat (see Figures 1 and 2). This process may be used as well for laminating sheets or plates
Figure 1 — Press for compression moulding shown with mould open and loaded with moulding material
Figure 2 — Press for compression moulding shown with mould closed and moulding material formed into shape
3.1.2 transfer moulding process in which the moulding material is fed into a separate cavity (transfer cavity) in the mould and is pressed into the moulding cavity by the pressure of the transfer plunger. The movement of the transfer plunger is obtained either directly by the closing movement of the mould (see Figures 3 and 4) or via a separate cylinder (see Figures 5 and 6)
NOTE If the moulding material is injected into the closed mould through a nozzle, see EN 201.

3.3 clamping unit the part of the press comprising fixed and mobile platens and associated drive mechanism.
3.4 shuttle/turntable machine press designed to contain one or more moulds attached to a table. The table indexes the mould(s) by a sliding or rotary motion between the loading/unloading station and the moulding position
3.5 ancillary equipment equipment which interacts with the press, e.g. loading and unloading devices (including heating stations, sliding tables, robots, plasticizing units) and power operated mould clamping devices
4 List of significant hazards 4.1 General This clause lists the significant hazards associated with presses. This document differentiates between:  general hazards;  hazards in specific machine areas;  additional hazards associated with specific design;  additional hazards when using ancillary equipment.

In addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards, which are not dealt with by this document (e.g. sharp edges). The machine shall be so designed that it is only possible to move the platen for setting operations with guards closed and/or protective devices in operation. The emergency stop equipment shall be in accordance with category 0 of EN 418:1992 when an uncontrolled stop (see 3.56 of EN 60204-1:1997) provides the shortest stopping time without creating additional hazards. In other cases, category 1 shall be applied. An emergency stop actuator shall be positioned within reach of any workplace which may be occupied by an operator.
Additional emergency stop actuators may be necessary in the case where whole body access to a danger area is possible (see 5.5.1 and 5.5.2). See 7.1.3. 5.2 Main safeguards used on presses 5.2.1 General Apart from fixed guards, the main safeguards used on presses belong to three groups. The classification system described in this sub-clause is based on the integrity of the devices and the associated control system. The groups do not indicate the suitability of any device for a particular application; the selection of the appropriate safeguard groups according to the risk assessment for particular hazards is given in 5.3 to 5.6. 5.2.2 Safeguard group I This group comprises: SIST EN 289:2004+A1:2008

They shall preferably be mounted on or close to the press. Safety distances for guards shall be in accordance with EN 294:1992, Table 1 and/or 4. Movable interlocking guards shall be positioned such that when the guard is opened the dangerous movement has come to a stop before access to the danger zone is possible. 5.2.5.2 Electro-sensitive protective equipment in the form of light curtains The light curtain shall become effective as soon as the press is switched on. The positioning of the light curtain shall take into account the formulas given in EN 999:1998. SIST EN 289:2004+A1:2008
