Описание (английский):

ISO 16156:2004 sets out the requirements and/or measures to remove the hazards and limit the risk on work holding chucks. It covers all the hazards relevant to this component. The requirements concern designers, manufacturers, suppliers and importers of work holding chucks. It also includes information which the manufacturer shall provide for the user. It is primarily directed to components which are manufactured after its date of issue.

Overview

ISO 16156:2004 - Machine-tools safety - Safety requirements for the design and construction of work holding chucks - specifies safety requirements and information that designers, manufacturers, suppliers and importers must provide to remove hazards and limit risk associated with work holding chucks. The standard addresses hazards such as crushing, entanglement, drawing-in/trapping, impact and ejection, and is intended mainly for chucks manufactured after the publication date. ISO 16156:2004 also supports conformity with the EU Machinery Directive by defining essential safety measures and user information.

Key Topics

Scope and definitions: clear terms for chuck types (manually operated, power‑operated, compensated/non‑compensated), jaws, clamping force (static/dynamic), maximum rotational speed (n_max), and balance.

Hazard list: identifies significant risks (crushing, entanglement, drawing‑in, impact, ejection).

Design and construction requirements:

Provide compatible actuating equipment and specify interface conditions between chuck and actuator.
Prevent base jaws from being flung out (locking pins or equivalent).
Chucks > 20 kg must include handling provisions (e.g., threaded lifting holes).
Balance quality factor (G) must be supplied (see ISO 1940‑1).

Speed and clamping limits:

Manufacturer must state maximum rotational speed (n_max).
For non‑compensated chucks, n_max must not exceed the speed at which static clamping force would fall by 67% under standard jaws.

Power‑operated chuck controls:

Devices to ensure effective clamping (e.g., travel sensors).
Pressure retention devices for actuator supply failures (e.g., check valves in line with EN 982/983).

Special features and accessories:

Wrench design must prevent tools remaining in rotating chuck (self‑removing or interlocking).
Grooves/slots require safety devices to prevent ejection of stops or counterweights.

Instruction handbook & marking:

Mandatory user information: clamping force determination, dynamic clamping variation, jaw mass limits, maintenance intervals, interchangeability references.
Indelible markings on chuck, jaws and clamping cylinders (manufacturer, type/serial, n_max, maximum input force/torque, measured static clamping force).

Applications

ISO 16156:2004 is used by:

Machine tool designers and chuck manufacturers for safe product design and compliance.

Equipment suppliers and importers to specify and certify safe chucks.

Safety engineers, maintenance staff and operators to select, install, verify and maintain chucks safely.

Conformity assessors and purchasers requiring documentation for Machinery Directive compliance.

Keywords: ISO 16156:2004, work holding chucks, machine-tools safety, clamping force, maximum rotational speed, power-operated chuck, chuck marking.
