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.

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.
