SAW TABLES FOR USE AS SAW BENCHES –

TABLES FOR HAND-HELD CIRCULAR SAWS WITH A

MAXIMUM SAW-BLADE DIAMETER OF 315 mm –

SAFETY REQUIREMENTS
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61939 has been prepared by subcommittee 61F: Safety of hand-
held motor-operated electric tools, of IEC technical committee 61: Safety of household and
similar electrical appliances.
The text of this standard is based on the following documents:
FDIS Report on voting
61F/322/FDIS 61F/360/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged until
2003. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

SAW TABLES FOR USE AS SAW BENCHES –

TABLES FOR HAND-HELD CIRCULAR SAWS WITH A

MAXIMUM SAW-BLADE DIAMETER OF 315 mm –

SAFETY REQUIREMENTS
1 Scope
This International Standard applies to tables for hand-held circular saws with a maximum saw-
blade diameter of 315 mm for use as circular saw benches.
NOTE For hand-held circular saws, IEC 60745-2-5 applies in conjunction with IEC 60745-1.
2 Normative References
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.
IEC 60529:1989, Degrees of protection provided by enclosures (IP Code)
IEC 60745-1:1997, Safety of hand-held motor-operated electric tools – Part 1: General
requirements
IEC 60745-2-5:1993, Safety of hand-held motor-operated electric tools – Part 2-5: Particular
requirements for circular saws and circular knives
3 Definition
For the purposes of this International Standard, the following definition applies:
3.1
saw table for circular saws
device with which a hand-held circular saw can be used as a circular saw bench (see
figure 1).
4 General requirements
The saw table shall include the equipment needed to fasten the hand-held circular saw which
is to be mounted on the table. The table shall be provided with means to positively locate and
secure the circular saw in its operating position. Screw fixing shall be fitted with anti-
loosening devices, e.g. locking washers.
Compliance is checked by inspection.

5 Guarding devices below the table

It is assumed that circular saws installed in the saw tables for stationary use shall comply with

IEC 60745-2-5. When the saw is mounted on the saw table, the guarding of the rim of the

blade above the guide plate, as specified in the above standard, shall not be impaired at any

depth of cut or angle which may be set. If the design of the table is such that the guide plate

of the saw is not in contact with the table, the saw blade between the guide plate and the
table shall be guarded by a fixed guard.

Compliance is checked by inspection and by the use of the test probe "a" (see figure 105 in

IEC 60745-2-5) to check accessibility of the saw blade teeth of all saws recommended by the

manufacturer.
6 Guarding devices above the table
6.1 Saw guard
A saw guard shall be provided to guard that portion of the blade above the table. This guard
shall have the following characteristics:
• The material from which the guard is made shall be such that in the event of contact
between the guard and the revolving saw blade, the guard will not disintegrate, and the
possibility of the saw blade disintegration or detachment of the teeth will be minimized.
Examples of such materials are polycarbonate, wood and aluminium. On non-transparent
guards, the line of the cut shall be indicated or shall be visible.
• The guard shall encompass the saw blade when it is in its highest position on the table.
• The side walls shall either have a minimum thickness of 6 mm or shall have internal ribs
with minimum thickness of 3 mm designed to bear against the body of the saw blade in
order to minimize the risk of damage to the guard (see figure 2).
• The infeed end of the base of the saw guard shall have a "lead in" with maximum
dimensions as shown in figure 3, in order to avoid mis-feeding, should the guard be
incorrectly set or the workpiece be uneven.
• The saw guard shall be mounted separately from the riving knife but integral with the saw
table. The support for the guard shall not be in line with the riving knife.
• The top guard shall cover the top and the sides of the saw blade and shall be capable of
being raised and lowered so that when the saw table is fitted with the circular saw having
the largest saw blade, the bottom edge of the guard can be raised to a minimum height of
50% of the length of the table slot above the uppermost saw teeth, and the guard can be
lowered to table level.
• The maximum inside width of the saw guard at its base shall be 40 mm, except on tables
for circular saws which have the facility to cant the saw blade.

• With the saw guard in its lowest position, the height of the saw blade shall be visible from
the point at which the operator adjusts the saw blade height.
• The guard shall be fitted with an exhaust outlet.
Compliance is checked by inspection and measurement.
6.2 Saw guard support system
6.2.1 The saw guard support system shall be so designed that the saw guard can either be
self-closing or manually adjustable to any permitted height.
The security arrangements for the saw guard support shall be such that adjustments can be
made without the aid of a tool and positive stops provided to locate the guard in its normal
working position.
Compliance is checked by inspection.
