This European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of weldable fine grain steels with high proof strength. NOTE Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done. The series EN 10222-1 to EN 10222-5 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5. General information on technical delivery conditions is given in EN 10021.

This document applies for plant (containing machinery and equipment) used in the process of continuous casting of liquid steel (hereafter referred to as continuous casting machine, CCM) as defined in 3.1. This document deals with all significant hazards, hazardous situations and events relevant to machinery and equipment for the continuous casting of steel, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This document specifies the safety requirements to be met during design, assembly, transport, commissioning, operation, maintenance (as described in Clause 5) and decommissioning of the equipment. This document assumes that the machinery and equipment of the plant is operated and maintained by adequately trained and competent personnel (see 7.5). Manual intervention for setting, adjustment and maintenance is accepted as part of the intended use of the plant. This document assumes that the machinery is used with adequate workstation lighting conforming to EN 12464-1. NOTE National regulations regarding lighting should be considered and could differ from requirements of EN 12464-1. This document applies to: CCM for the transformation of molten liquid steel into solid products in sections (e.g., square, rectangular, beam blank, circular) - CCM's from the point where overhead cranes or other transport systems deposit ladles to CCM (e.g., in a ladle turret, ladle car or ladle stand); - via casting process and solidification process; - via cutting equipment; - thru the run-out-area where the cut product is finished, collected and removed from that area. This document does not cover safety requirements for: - horizontal-CCM for steel; - auxiliary plants (e.g., water treatment, refractory handling); - ladles; - cranes; - winches and hoists; - conveyors or handling systems; - workshop equipment (mould and segment shop, tundish workshop). NOTE It is recommended to use this standard in case of modernization for the parts to be modernized.

This document specifies the general safety requirements for hot rolling mills for flat products as defined in 3.1. This document is applicable to: Plant (machinery, equipment, devices according Annex D) used for the manufacturing of metal hot rolled flat products from the material supply from entry (1), via the mill stands (2) with roll changing devices (6), to the exit (5) (see Figure 1). Figure 1.... This standard does not cover: - thermo process equipment, e.g. in accordance with the EN 746 series; - continuous casting machines according to EN 14753; - hook conveyors according to EN 619; - non-fixed load lifting attachments, e.g. according to EN 13155; - roll shop equipment; - storage equipment (e.g. high-bay warehouses); - cranes, fork lifts, trucks and railway trucks and other vehicles; - process technology (e.g. treatment of water, rolling lubricant, compressed air, etc.); - separate cleaning system for exhaust air; - firefighting system. NOTE 1 Special requirements for protection of persons in case of using asphyxiant gases used in firefighting system is covered by this document (see Annex C). This document deals with significant hazards, hazardous situations or hazardous events relevant to hot rolling mills for flat products, when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. It provides the requirements to be met by the manufacturer to ensure the safety of persons and property during transport, commissioning, operation and de-commissioning, as well as in the event of foreseeable failures or malfunctions that can occur in the equipment. NOTE 2 For modernization, this document (C-type standard) can be applied for the part to be modernized.
