Machine tools - Safety - Stationary grinding machines (ISO 16089:2015)

ISO 16089:2015 specifies the requirements and/or measures to eliminate the hazards or reduce the risks in the following groups of stationary grinding machines which are designed primarily to shape metal by grinding:
Group 1: Manually controlled grinding machines without power operated axes and without numerical control.
Group 2: Manually controlled grinding machines with power operated axes and limited numerically controlled capability, if applicable.
Group 3: Numerically controlled grinding machines.
NOTE 1       For detailed information on the groups of grinding machines, see the definitions in 3.1 and 3.4.
NOTE 2       Requirements in this International Standard are, in general, applicable to all groups of grinding machines. If requirements are applicable to some special group(s) of grinding machines only, then the special group(s) of grinding machine(s) is/are specified.
This International Standard covers the significant hazards listed in Clause 4 and applies to ancillary devices (e.g. for workpieces, tools, and workpiece holding devices, handling devices), which are integral to the machine.
This International Standard also applies to machines which are integrated into an automatic production line or grinding cell inasmuch as the hazards and risks arising are comparable to those of machines working separately.
This International Standard also includes in Clause 7 a minimum list of safety-relevant information which the manufacturer has to provide to the user. See also ISO 12100:2010, Figure 2, which illustrates the interaction of manufacturer's and user's responsibility for the operational safety.
The user's responsibility to identify specific hazards (e.g. fire and explosion) and reduce the associated risks can be critical (e.g. whether the central extraction system is working correctly).
Where additional metalworking processes (e.g. milling, turning, laser processing) are involved, this International Standard can be taken as a basis for safety requirements. For specific information on hazards arising from other metalworking processes, which are covered by other International Standards, see the Bibliography.
This International Standard applies to machines that are manufactured after the date of issue of this International Standard.
This International Standard does not apply to stationary honing, polishing, and belt grinding machines and not to transportable motor-operated electric tools in accordance with IEC 61029‑2‑4 and IEC 61029‑2‑10.

Foreword
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
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is Technical Committee ISO/TC 39, Machine tools,
Subcommittee SC 10, Safety.
This first edition of ISO 16089 is an adaptation of European Standard EN 13218:2002+A1/AC:2010-04.
Significant differences between the European Standard and ISO 16089 are as follows.
a) Introduction of a subdivision of grinding machines into three groups, based on the degree of
automation. Specific safety measures for safe design for each group of grinding machines.
b) Introduction of the Mode of safe operation 3 (optional special mode for manual intervention under
restricted operating conditions) with a separate selection device and specific safety measures, and a
new informative Annex providing examples.
c) Instead of the categories of EN 954-1, the required performance level according to ISO 13849-1 is
defined for relevant safety functions.
d) The decrease in the impact resistance of unprotected polycarbonate depending on the duration of
use is shown in the form of an aging curve in Annex A.
e) Measures for the use of flammable metalworking fluids are given in the new Annex H.
f) Examples for the integration of extraction and fire extinguishing systems when using flammable
metalworking fluids are given in the new Annex I.
g) Example for rotational speed limit monitoring of the wheel spindle given in the new Annex K.
ISO 16089:2015(E)
Introduction
In order to take technological progress into account, it was decided to revise EN 13218 for this purpose.
Due to the worldwide use of these machines, an agreement was made by CEN/TC 143 and ISO/TC 39/SC
10. According to the Vienna Agreement, this revision was carried out as ISO 16089.
A decisive aspect for the preparation of this standard was the consideration of foreseeable misuse, e.g.
by means of manipulation of protective devices.
Safety measures for grinding machines are, in particular, characterized by guards with interlocking
and guard locking, to effectively counteract risks of fracture of ceramic tools. In some special cases
of grinding operations, guards can be regarded as disturbing by the operator because they obstruct
process monitoring. Then, by means of manipulation of the interlocking devices, automatic mode
without guard can occur with dramatically increased hazards for the operator. To reduce the incentive
for manipulation, the possibility of using a special mode (MSO 3) was provided in the operating mode
concept for grinding machines such as in the preceding standard EN 13218. This implies the same strong
safety measures as for the operating mode setting. These restrictions offer a significant motivation
for switching back into automatic mode where higher speeds and feed rates are available for a more
profitable production. Comparisons of risks show that the provision of a special mode presents a much
lower risk than a manipulated automatic mode.
At the time this International Standard was developed, it was already foreseen that the information
given in A.3.2 on the wall thickness of abrasive product guards and in A.3.5 on the work zone enclosure
will probably be modified by an Amendment to this International Standard, depending on the result of
further scientific research.

INTERNATIONAL STANDARD ISO 16089:2015(E)
Machine tools — Safety — Stationary grinding machines
1 Scope
This International Standard specifies the requirements and/or measures to eliminate the hazards or
reduce the risks in the following groups of stationary grinding machines which are designed primarily
to shape metal by grinding:
Group 1: Manually controlled grinding machines without power operated axes and without
numerical control.
Group 2: Manually controlled grinding machines with power operated axes and limited numerically
controlled capability, if applicable.
Group 3: Numerically controlled grinding machines.
NOTE 1 For detailed information on the groups of grinding machines, see the definitions in 3.1 and 3.4.
NOTE 2 Requirements in this International Standard are, in general, applicable to all groups of grinding
machines. If requirements are applicable to some special group(s) of grinding machines only, then the special
group(s) of grinding machine(s) is/are specified.
This International Standard covers the significant hazards listed in Clause 4 and applies to ancillary
devices (e.g. for workpieces, tools, and workpiece holding devices, handling devices), which are integral
to the machine.
This International Standard also applies to machines which are integrated into an automatic production
line or grinding cell inasmuch as the hazards and risks arising are comparable to those of machines
working separately.
This International Standard also includes in Clause 7 a minimum list of safety-relevant information
which the manufacturer has to provide to the user. See also ISO 12100:2010, Figure 2, which illustrates
the interaction of manufacturer’s and user’s responsibility for the operational safety.
The user’s responsibility to identify specific hazards (e.g. fire and explosion) and reduce the associated
risks can be critical (e.g. whether the central extraction system is working correctly).
Where additional metalworking processes (e.g. milling, turning, laser processing) are involved, this
International Standard can be taken as a basis for safety requirements. For specific information
on hazards arising from other metalworking processes, which are covered by other International
Standards, see the Bibliography.
This International Standard applies to machines that are manufactured after the date of issue of this
International Standard.
This International Standard does not apply to stationary honing, polishing, and belt grinding machines
and not to transportable motor-operated electric tools in accordance with IEC 61029-2-4 and
IEC 61029-2-10.
