ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

4.4.1 Cover

Shearing and pinching hazards in case of unintentional closing (for example due to wind) shall be

avoided.

If a hopper cover is provided and if the mass of the cover is greater than 10 kg, means shall be provided

to retain the cover to the hopper and the cover shall be provided with one or more handles. The handles

may be integral parts of the cover, provided the handles are suitable designed and clearly identified

(e.g. by shape or colour).
4.4.2 Moving components

4.4.2.1 For machines with moving components inside the hopper such as rotating agitators or

feed augers which show an entanglement, drawing-in, crushing or shearing hazard, access to these

components shall be prevented by
— fixed guard according to ISO 12100:2010, 6.3.3.2.2 and ISO 14120, or

— movable guard which remains attached to the machine when opened (e.g. by means of hinges) and

automatically locks in the closed position without the use of a tool and needing a tool to be opened, or

— a combination of fixed and movable guards (in case a grid is used as guard, the grid apertures and

location shall comply with the safety distances given in ISO 13857:2008, Tables 3, 4 and 6 in closed

position), or

— guard that causes the drive of the moving components to stop when opened or removed and prevents

starting with the guard open, or

— designing the access to the hopper in such a way that access to hazardous components is prevented

when in motion and the movement of the hazardous components is prevented when access means

are in the position for use.

For specific operations (e.g. calibration of the flow rate, emptying of residues, cleaning) starting the

moving components shall be possible only if additional safety measures are applied, e.g. limitation of

speed, hold-to-run control.

These requirements shall be verified by inspection and measurement. See also 6.1 f), g), h), i) and j).

When in the closed position, this guard (grid) shall meet the strength requirement for the vertical load

as specified in ISO 4254-1:2013, 4.10.

If the manufacturer recommends the use of a special device (e.g. a hand rake) in the operator's manual

in order to facilitate the filling or to remove blockages, this device and a location on the machine for

storage in the filling area shall be provided. See also 6.1 k).
