Overview
EN 14673:2006+A1:2010 is a CEN Type C standard that defines health and safety requirements for hydraulically powered open die hot forging presses used for forging steel and non‑ferrous metals. It covers the press and associated handling/cooling equipment that is connected to the forging line control system, and handling equipment specifically designed for use within the forging line. The standard addresses safety across the equipment life cycle - design, construction, transport, commissioning, operation, maintenance, de‑commissioning and disposal - and deals with significant hazards foreseeable by the manufacturer.
Key scope points
- Applies to: hydraulically powered open die hot forging presses; manipulators, rotating handling devices, die shifting and tool changing devices; material manipulation devices designed for the forging line.
- Excludes: hydraulically controlled closed‑die presses, mechanically powered hot forging presses, mobile manipulators (as defined), and standard transport/lifting equipment modified for material handling.
- Not applicable to machinery manufactured before publication.
Key topics and technical requirements
EN 14673 specifies requirements and measures related to:
- Hazard identification and risk reduction - lists significant hazards and required safety measures for intended and foreseeable uses.
- Safety control systems - requirements for electrical and control systems to ensure safe operation and stop functions.
- Hydraulic, pneumatic, cooling and lubrication systems - safe design, pressure control and failure modes (Annex A normative).
- Guards, access and operator visibility - layout and guarding to prevent access to dangerous areas.
- Safety devices and emergency stop - selection, placement and verification of devices and stop functions (Annex B normative).
- Noise management - noise test code, declaration and reduction measures at source, by protection and by PPE (Annex C).
- Ergonomics, vibrations, surface temperatures and fire safety - design considerations to protect personnel.
- Verification and documentation - testing, verification of safety requirements, marking, and detailed information for use and maintenance manuals.
- De‑commissioning - guidance on safe end‑of‑life measures (informative Annex D).
- Conformity with EU law - relationship to Directive 2006/42/EC (Annex ZA informative).
Applications and who uses this standard
EN 14673 is essential for:
- Manufacturers of hydraulically powered open die hot forging presses to design and certify safe machinery.
- Machine designers and integrators who install presses and linked handling/cooling equipment into forging lines.
- Safety engineers and compliance officers performing risk assessments and conformity verification.
- Maintenance personnel and plant managers responsible for safe operation, maintenance manuals and de‑commissioning.
- Procurement and inspection bodies specifying safety requirements in bids and acceptance testing.
Related standards
- EN ISO 12100 (general principles for risk assessment and reduction) - EN 14673 is a Type C standard under this framework.
- Annex ZA of EN 14673 maps the standard to EU Machinery Directive 2006/42/EC for legal conformity.
Use EN 14673 for authoritative guidance when specifying or assessing the safety of hydraulically powered open die hot forging presses and their integrated handling systems.

NOTE Definitions used in EN and ISO standards referred to in this European Standard are also valid for this European Standard. 3.1 hydraulically powered open die hot forging press machine, which is hydraulically powered and which is used for the mechanical forming of hot metals between flat or shaped dies where flow of the metal is not completely restricted SIST EN 14673:2007+A1:2010
EN ISO 14121-1:2007. However, guard-rails, are not to be considered as sufficient measures of safeguarding to address hazardous situations included in Table 1, where only significant hazards are dealt with. In addition, the manufacturer shall give information in the instructions for use (see Clause 7) about the foreseen restrictions for access to the areas surrounded by the guard-rails and about the nature of the existing residual risks." 5.1.7 Discharge of fluids The manufacturer shall give instructions for discharge of fluids in case of internal leakage or due to maintenance of the fluid systems. This shall include information for tight surfaces, drains and the material that will be discharged. 5.1.8 Personal protective equipment (PPE) The manufacturer shall give information in the Information for use manual (see 7.5) on the required type of personal protective equipment needed to safeguard personnel from any risks remaining after applying the safety measures. 5.1.9 Warning devices and safety signs Warning devices and safety signs are additions to the design requirements to reduce hazards in case of significant risks. Safety signs and warning devices according to EN 61310-1 and -2 shall be used. Graphical symbols shall be in accordance with ISO 3864-1 and/or ISO 7000. Danger signals shall be in accordance with EN ISO 7731 and/or EN 842 and/or EN 981. Warning signs shall be affixed so that they are visible from outside the danger zone. !Warning signs about non-ionising radiation for persons with implanted medical devices shall be fixed where applicable." If an audible warning device is required (e. g., horn), the A-weighted sound pressure level measured according to EN ISO 7731 shall be 10 dB higher than the environmental noise of the operating forging presses, measured at 7 m distance from the audible warning device. NOTE The manufacturer should not rely upon warning signs alone to reduce hazards in the case of significant risks being present. 5.1.10 Access The manufacturer shall define and discuss the final overall design and layout of the plant to prevent unintentional access. In particular, the manufacturer shall take account of the following: SIST EN 14673:2007+A1:2010
!EN ISO 13849-1". The function of each safety control shall be considered in combination with other elements of the safety control system and shall maintain the safety level of all other components of the control system. For the hazards listed in Table 1 where an electrical control system is involved a risk assessment has been carried out according to !EN ISO 13849-1". 5.1.13 Guards !Guards shall be provided to prevent access to a danger zone. They shall be selected as appropriate for the degree and frequency of access to be permitted, e.g. an enclosing guard or distance guard, fixed or movable with interlock. This selection shall be made according to EN 953. Interlock systems shall meet the requirements of EN 1088. The requirements for guards shall conform to Clause 5 of EN 953:1997, EN ISO 13857 and EN 349. At zones, where risks due to potentially danger movements of equipment exist, operation of manual modes shall be made by means of hold-to-run devices from control stands with full overview of the driving elements." 5.1.14 !Surface temperatures and heat radiation" !Surfaces which are accessible and could be touched shall have temperatures not exceeding the burn threshold for contact time and material specified in EN ISO 13732-1. Where these limits can not be kept, additional technical measures shall be applied, e.g. isolation, distance guard. These measures shall be supplemented by warning instructions and wearing of PPE, if necessary. SIST EN 14673:2007+A1:2010
