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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.

4 Safety requirements and/or protective measures
4.1 General
The machine shall comply with the safety requirements and/or protective measures and be verified in accordance
with Clause 5. In addition, the machine shall be designed in accordance with the principles of ISO 12100 for
relevant, but not necessarily significant, hazards, which are not dealt with by this part of ISO 11148.
The measures adopted to comply with the requirements of this clause shall take account of the state-of-the-art.
It is recognized that optimizing the design with respect to some safety measures can result in a degradation of
performance against other safety requirements. In such cases, it is required to strike a balance between the
various requirements in order to achieve a circular, oscillating or reciprocating saw design that satisfies each
requirement, so far as is reasonably practicable, and remains fit for purpose.
4.2 Mechanical safety
4.2.1 Surfaces, edges and corners
Accessible parts of circular, oscillating and reciprocating saws, except the inserted tool, shall not have sharp
edges or angles or rough or abrasive surfaces; see ISO 12100:2010, 6.2.2.1.
4.2.2 Supporting surface and stability
Circular, oscillating and reciprocating saws shall be so designed that they can be laid aside and remain in a
stable position on a plane surface.
4.2.3 Flanges
Flanges for circular saws, for clamping the saw blade to the working spindle shall be of equal size, and of a size
not less than 0,3 times the rated diameter of the blade.
4.2.4 Hydraulic fluid ejection
Hydraulic systems of the circular, oscillating and reciprocating saws shall be enclosed so as to give protection
against high-pressure fluid ejection.
4.2.5 Guide plate
Circular saws shall have a guide plate of a size and shape to support the saw against the material being cut.
The guide plate shall be securely fastened to the saw housing. If the blade exposure angle, α ,below the guide
plate (see Figure 1) exceeds 10°, the guide plate shall have an outboard section (see Figure 2). The outboard
section shall enclose the full diameter of the saw blade and its outer edge shall not be less than 25 mm from
the face of the blade, H in Figure 2. The distance between the periphery of the largest specified blade to the
front edge of the base plate, F, shall be larger than 13 mm. The angle in Figure 1 shall be measured between
the intersections of the blade tip circle with the underside of the base and each side of the lower guard.
