Overview
EN ISO 16092-4:2020 (ISO 16092-4:2019) - "Machine tools safety - Presses - Part 4: Safety requirements for pneumatic presses" is a CEN-adopted type‑C standard that specifies technical safety requirements for the design, manufacture and supply of pneumatic presses used for cold metal working. It supplements ISO 16092-1 and takes into account all life‑cycle phases defined in ISO 12100:2010, addressing significant hazards during intended use and reasonably foreseeable misuse.
Key Topics
- Scope and hazard identification: lists significant hazards specific to pneumatic presses and the conditions of misuse manufacturers should consider.
- Design considerations: requirements for pneumatic systems and common features shared with hydraulic/electric systems, emphasizing safe energy supply and failure modes.
- Mechanical safeguarding: protective measures for the tools area, definition of major danger zones, guarding requirements and procedures for release of trapped persons.
- Control and monitoring systems: control functions, muting, selection devices, position sensors, control devices, valves and required performance levels for safety functions.
- Tool-setting and maintenance: safe procedures for tool-setting, trial strokes, maintenance and lubrication.
- Verification and information for use: conformity verification, marking, warnings and requirements for the instruction handbook.
- Annexes: calculation of minimum distances (Annex B) and examples/principles of pneumatic press interlocking (Annex C), plus additional hazard guidance.
Practical Applications
- Use this standard to implement and verify safety requirements for pneumatic presses during product development, factory acceptance and risk assessment.
- Apply the guidance to design safe pneumatic systems, select appropriate valves and position sensors, and define interlocks and control logic to prevent uncontrolled movements and ejection hazards.
- Incorporate the standard into machine documentation: CE conformity packages, instruction handbooks, maintenance procedures and operator training materials.
- Support compliance with the EU Machinery Directive (2006/42/EC) - Annex ZA maps this standard to essential requirements of the Directive, assisting manufacturers seeking presumption of conformity.
Who Should Use It
- Machine manufacturers and designers of pneumatic presses and press lines
- System integrators and safety engineers implementing press controls and guards
- Maintenance personnel and safety officers preparing procedures and lockout/tagout
- Regulators, conformity assessment bodies and market surveillance authorities
- Health & safety professionals performing risk assessments on press equipment
