The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. Where for clarity an example of a preventative measure is given in the text, this should not be considered as the only possible solution. Other solutions can be used as far as they fulfil correctly the criteria expressed in the requirement. This European Standard assumes, that the equipment is operated and maintained by trained personnel." 1 Scope This document specifies requirements to be met by the manufacturer for the foreseeable significant hazards due to design, construction and installation, during commissioning, operation, maintenance, and decommissioning of the following machines and equipment which are used directly and indirectly for the manufacture of castings:  Ladles;  Pouring equipment;  Centrifugal casting machines for production of tubes (only machines with horizontal or oblique axis of rotation);  Continuous and semi continuous casting machines for non-ferrous metals.

3 Terms and definitions !For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following apply. NOTE Definitions used in EN and ISO standards referred to in this European Standard are also valid for this European Standard." SIST EN 1247:2004+A1:2010

EN 1247:2004+A1:2010 (E) 7 3.1 ladle tiltable vessel with or without hanger with or without refractory lining designed to contain, transport and discharge molten material (see Annex B, Figures B.1 and B.2). NOTE The tilting movement is often achieved by power driven tilting drives. Sometimes ladles are bottom discharging. In this case discharging is achieved by moving a stopper rod (see Annex B, Figure B.2) or a hydraulically or pneumatically driven bottom slide gate nozzle. Ladles are usually transported by hoists and have their own hanger which is integral to the ladle. Sometimes ladles are transported by floor based trucks or fork lift trucks. 3.2 tundish refractory lined vessel with a discharge at its bottom which may be interposed between the ladle and the mould in teeming 3.3 pouring equipment mechanically or electrically driven device (see Annex B, !Figure B.5") which stores and delivers molten metal to the mould as part of an automatic or semi automatic integrated casting plant

NOTE This equipment consists of a vessel, heated or unheated, with or without a metering device, for delivery of molten metal to the mould by gravity, or by applying air or inert gas pressure or vacuum onto the surface of the molten metal in the vessel. Heated vessels are also called furnaces. 3.4 centrifugal casting machine machine to manufacture tubes by centrifugal means. The axis of the tube coincides with the axis of rotation and where the thickness of the tube is determined by the dimensions of the mould and the amount of metal cast (see Annex B, Figure B.7). The said axis may be horizontal or oblique (vertical axis of rotation is excluded, see Clause 1) 3.5 continuous and semi continuous casting machine machine which provides a regular or intermittent supply of liquid metal (for this document: non-ferrous metal only, see Clause 1) to a mould, from where the solidified product leaves under gravity or by powered means

Depending upon the direction in which the bar leaves the tundish distinction is made between vertical and horizontal casting. Additionally, distinction is made between continuous and semi continuous casting as to whether the bar is cast without interruption and cut with a flying saw or is stopped after reaching a determined length and is then completely removed from the equipment. In the non-ferrous metals sector the semi continuous casting process is mainly used. 3.6 metering monitoring the amount of liquid metal 3.7 breakthrough refractory lining of the pouring equipment is penetrated by molten metal 3.8 stripping/ejection of castings removal of the centrifugal casting from the mould after solidification ! 3.9 dynamically self-locking a gearbox meets the requirements for dynamically self-locking, if the geared motor drive stops immediately or after a short time after switch-off even if a torque is acting at the output side of the gearbox NOTE Dynamic automatic locking is only possible at very high transmissions ratios and in low drive speed ranges."

In addition, the machines shall be designed according to the principles of EN ISO 12100-2 for relevant but not significant hazards which are not dealt with by this document. For application of type B standards such as EN ISO 13857, EN 349, EN 982, EN 983, EN 1037, EN 60204-1, EN ISO 13850, EN ISO 14122-1, EN ISO 14122-2, EN ISO 14122-3, EN ISO 14122-4, the manufacturer shall carry out an adequate risk assessment for the requirements thereof where choice is necessary (as far as the choice is not made in the requirements of this clause)." 5.1.2 Where the means of reducing the risk is by the physical arrangement or positioning of the installed machines, the manufacturer shall include in the Information for use a reference to the reduction means to be provided, and to any limiting value of the requirement, and, if appropriate, to the means of verification. 5.1.3 Where the means of reducing the risk is by a safe system of working, the manufacturer shall include in the Information for use details of the system and of the elements of information required by the operating personnel. This shall include arrangements to run a machine for essential operating reasons or in special mode with safety devices suspended or temporarily modified. 5.1.4 It is recognised that a general hazard exists of exposure to high temperature surfaces which may be touched and which is not practicable to eliminate. The manufacturers information for use shall contain guidance to the user on the preventative measures to be used in connection with contact to hot surfaces and the need to provide the operator(s) with PPE as appropriate. 5.1.5 !If access to a danger zone is required for any reason during normal operation, commissioning, setting up, production, maintenance, decommissioning (see 5.2.3 of EN ISO 12100-2:2003), the parts of the control system related to the guarding or safety devices for ensuring safety during access, shall present at least a performance level PL = d while using a category 3 architecture as defined in EN ISO 13849-1:2008, except for hydraulic equipment for which the performance level PL = c while using a category 1 architecture." 5.1.6 Required guards and enclosures shall be made in such a way that injuries caused by metal eruptions are prevented. 5.1.7 !The following Table 1 is developed to allow the designer and manufacturer of the equipment to apply a logical approach for checking the design against the list of significant hazards with respect to the equipment covered by this standard. Table 1 is structured as follows:  column 1 identifies the significant hazards;  column 2 describes the hazardous situations; SIST EN 1247:2004+A1:2010

EN 1247:2004+A1:2010 (E) 9  column 3 specifies the safety requirements and/or measures to avoid or minimize the hazards and hazardous situations. They shall be provided in a cumulative manner if not otherwise stated; NOTE When implementing safety requirements and/or measures it should be considered that different hazards may appear at the same time.  column 4 identifies the verification method to be used to demonstrate conformity; the abbreviations V, F, M and D are defined as follows: V: Visual inspection verifies the required features of the components. F: A test/check verifies that the features provided perform their function in such a way that the requirement is met. M: Measurement verifies that requirements are met, to the specified limits. D: Drawings and/or calculations verify that the design characteristics of the components provided meet the requirements. Verification may involve more than one method." SIST EN 1247:2004+A1:2010

 Bottom pouring ladles  Information for use should advise the user that pouring zones and ladle filling areas in which bottom pouring ladles are used should have provisions to accommodate molten metal leakage (e. g., sand pits, pit moulds). V, D 5.2.3 Impact, burns  Unexpected upset of hanger or ladle.  Ladles shall be provided with devices to prevent ladle turning e.g., by a locking pin or mechanical latch. Such a device shall only be unlocked immediate before pouring. V, D SIST EN 1247:2004+A1:2010
