Overview
ISO 12643-5:2023 - Graphic technology - Safety requirements for graphic technology equipment and systems - Part 5: Manually-fed stand-alone platen presses defines safety requirements specific to manually-fed, stand‑alone platen presses used for cutting, creasing, embossing, foil stamping and printing of paper, board and similar materials. It covers single stroke, dwell (time‑controlled) and continuous operation modes, and excludes presses designed for metal materials other than foil. The standard supplements ISO 12643-1:2023 and focuses on machine design, guarding and safety-related control measures for platen presses.
Key technical topics and requirements
- Scope of application: Manually‑fed stand‑alone platen presses (single stroke, dwell, continuous). Excludes metal‑handling presses except foil.
- Guarding and protective devices: Fixed and movable guards per ISO 14120; safeguarding of side and front access; trip bars, knee bars and U‑shaped trip bars for operator protection.
- Sizing and placement rules:
- Platen presses with table width ≤ 1 m and depth ≤ 850 mm require trip bar(s) or equivalent.
- For platen presses > 1 m width or depth > 850 mm, U‑shaped trip bars alone are not sufficient - presence detection (ESPD such as laser scanners, vision based protective devices - VBPD, or equivalent) is required to detect persons on the platen.
- Knee bar clearance: at least 120 mm between knee bar and front surface of the open platen.
- Performance and safety integrity:
- Controls and stopping: Requirements for emergency stop, safety‑related stops, stopping distance and performance, main drive braking, clutch/brake mechanisms and flywheels.
- Detection technologies: Positioning and performance requirements for laser scanners and VBPDs, plus calculation of safety distances.
- Documentation and verification: Verification procedures and required contents of the instruction handbook are specified.
Practical applications and who uses this standard
ISO 12643-5:2023 is intended for:
- Machine manufacturers designing and building manually‑fed platen presses.
- Health & safety regulators and market surveillance bodies assessing machinery compliance.
- Plant engineers and maintenance teams implementing safeguarding and safety system upgrades.
- Buyers and end‑users selecting safe machinery for cutting, creasing, embossing, foil stamping or related graphic‑technology processes.
Use cases include retrofitting presence detection on wide platen presses, specifying trip bar/knee bar arrangements, validating safety‑related control performance levels, and preparing compliant operator manuals.
