EN ISO 16092-2:2020 PDF

Overview

EN ISO 16092-2:2020 (adoption of ISO 16092-2:2019) is the European/CEN standard that specifies safety requirements for mechanical presses used in metalworking. It is intended to be used together with ISO 16092-1 and covers two main groups of mechanical presses:

• Group 1: presses with part-revolution clutch(es)
• Group 2: presses with servo drive systems (mechanical servo presses - includes functionally similar drive systems such as variable frequency drives)

The standard addresses significant hazards associated with presses and integral ancillary devices (e.g., die cushions, ejectors, feeding and transfer systems) throughout the machine life cycle in line with ISO 12100.

Key topics and technical requirements

EN ISO 16092-2:2020 defines technical safety measures and verification requirements. Major topics include:

• Risk identification and list of significant hazards relevant to mechanical presses
• Basic design considerations for mechanical, hydraulic, pneumatic and electrical systems, including mechanical brakes, slide adjustment and counterbalance systems
• Safeguarding of the tools area (major danger zone), guarding choices and measures to prevent entrapment and ejection hazards
• Control and monitoring systems: required control/monitoring functions, muting, selection devices, position sensors, control devices and valves
• Performance requirements for safety functions (including single-stroke and stopping-performance/overrun monitoring)
• Operational modes and procedures: INCH mode, tool-setting, trial strokes, maintenance and lubrication requirements
• Verification and validation of safety requirements and testing
• Information for use: marking, warnings and instruction handbook content, stroke indication means
• Informative and normative annexes covering significant hazards, calculation of minimum distances, rotary cam settings and determination of stopping time for Group 1 presses

The standard explicitly excludes presses driven by hydraulic/pneumatic systems for slide motion, presses with slides moving in differing angular orientations, and linear-motor-driven slides.

Practical applications and users

EN ISO 16092-2 is essential for:

• Press manufacturers and design engineers specifying machine safety features
• System integrators and machine builders who supply press production systems
• Safety engineers, compliance managers and risk assessors responsible for machine conformity with CE/Machinery Directive (2006/42/EC)
• Maintenance teams and trainers who need procedures for safe tool-setting, trial runs and servicing
• Procurement specialists and inspectors evaluating press safety and conformity

Compliance with the standard supports a presumption of conformity with relevant essential requirements of the EU Machinery Directive (see Annex ZA).
