Overview
EN 1550:1997+A1:2008 - Machine-tools safety: Safety requirements for the design and construction of work holding chucks - is a CEN European Standard that specifies safety requirements and information for work holding chucks (clamping devices with movable jaws). It covers hazards relevant to chucks, prescribes design and marking requirements, and sets out the information manufacturers must supply to users. The standard supports conformity with the EU Machinery Directives (98/37/EC and 2006/42/EC).
Key topics and technical requirements
- Scope and users: Applies to designers, manufacturers, suppliers and importers of work holding chucks and to components produced after the standard’s issue.
- List of hazards (clause 4): crushing, entanglement, drawing-in/trapping, impact, ejection of parts.
- Design safety measures:
- Compatibility between chuck and its actuating equipment (cylinders).
- Provision of balance quality factor G (per ISO 1940-1).
- Prevention of base jaws being flung out by centrifugal forces (e.g., locking pins).
- Handling provisions for chucks with mass > 20 kg (e.g., lifting holes).
- Operational limits:
- Manufacturer must state maximum rotational speed (nmax). For non‑compensated chucks, nmax is limited by loss of clamping force criteria (see standard).
- Static and dynamic clamping force definitions and requirements; methods for determining clamping forces must be provided.
- Power and manual operation:
- Power‑operated chucks: devices to ensure clamping force is effectively applied; pressure retention measures on energy loss (EN 982/EN 983 referenced).
- Manual tools (wrenches): designed so they cannot remain in a rotating chuck (spring‑loaded removal or spindle interlock).
- Special features:
- Safety for chucks with grooves/slots (pins or retainers to prevent ejection).
- Requirements for centrifugally compensated chucks and limits on jaw mass/radius.
- Information & marking:
- Instruction handbook must include safety, handling, maintenance, clamping force methods, nmax, jaw mass limits, interchangeability references, and interface conditions.
- Marking: manufacturer name, type/serial number, max input force/torque, maximum measured static clamping force, and nmax.
Applications and who uses it
- Manufacturers and designers of power and manually operated chucks for machine tools.
- Machine-tool integrators, safety engineers, CE compliance assessors and technical buyers assessing chuck suitability.
- Maintenance teams and operators using the instruction handbook for safe operation, checking static clamping forces, and setting permissible machining speeds.
- Useful in risk assessments, procurement specifications, installation and maintenance procedures.
