---------------------- Page: 16 ----------------------

SIST EN ISO 11148-8:2012
ISO 11148-8:2011(E)
The measures adopted to comply with the requirements of Clause 4 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 sander or polisher 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 the sanders and polishers, 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
The sander or polisher shall be so designed that it can be laid aside and remain in a stable position on a plane
surface.
4.2.3 Run-down time
The run-down time, after the stop command has been given, shall be as short as possible.
4.2.4 Hydraulic fluid ejection
Hydraulic systems of the sander or polisher shall be enclosed so as to provide protection from high-pressure
fluid ejection.
4.2.5 Speed control
The rated speed of a rotary or belt sander or polisher shall not be exceeded under the conditions marked on
the sander or polisher. The operating speed of a rotary or belt sander shall never exceed the maximum
operating speed of accessories, such as a backing pad. It shall be possible to measure rotational speed by a
tachometer.
The speed control device of a rotary sander (where fitted) shall be designed to prevent incorrect assembly.
The speed control device shall be manufactured of non-corrodible material.
The maximum operating speed marked on backing pads and drums shall equal or exceed the rated speed
marked on the sander or polisher.
4.2.6 Power tool construction
The sander or polisher shall be so designed and constructed as to prevent the loosening or loss of
components during expected use, including rough handling and occasional dropping, which can compromise
its safety functions. Verification shall be carried out in accordance with 5.5.
4.2.7 Distance between moving and fixed parts
Polishers and sanders shall be designed so as not to allow fingers to be caught between the moving and fixed
parts.
4.2.8 Position of handles
The handles shall be so shaped and located as to minimize the risk of inadvertent contact of the operator's
hand with the rotating abrasive tool. Recommendations are given in ISO 13854.

4.2.9 Guards
Portable belt sanding machines shall be provided with guarding on one side at the nip point where the sanding
belt runs into a pulley.
The unused run of the sanding belt shall be guarded on one side and at the rear.
4.2.10 Backing pads and drums
Backing pads and drums for rotary sanders shall be capable of withstanding free rotational speeds of 120 %
of the maximum operating speed and shall be capable of withstanding the heat generated in use. The
manufacturer shall ensure that the material for the pad is suitable.
4.3 Thermal safety
Surface temperatures of parts of the sander or polisher which are held during use or which can be
inadvertently touched shall follow the provisions of ISO 13732-1 and ISO 13732-3.
Pneumatic tools shall be designed to minimize the cooling effects of exhaust air on the handles and other
gripping zones.
4.4 Noise reduction
The sander or polisher shall be designed and constructed so that the emission of noise is reduced to the
lowest level, taking account of technical progress and the availability of means of reducing noise, in particular
at the source. Principles for designing sanders and polishers with reduced noise emission are contained in
ISO/TR 11688-1 and ISO/TR 11688-2.
The noise emission from using sanders and polishers has three main sources:
 the sander or polisher itself;
 the inserted tool;
 the workpiece.
NOTE Generally, the noise emitted due to the characteristics of the workpiece cannot be controlled directly by the
manufacturer of the sander or polisher.
Typical sources of noise emitted by the sander or polisher itself are
a) the motor and drive mechanism,
b) the exhaust air or gases, and
c) vibration or impact-induced noise.
Where the exhaust air or gases are the major contributor to the noise, means to reduce the noise, for example
a silencer or equivalent means, shall be included in the design.

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.
ISO 11148-8 was prepared by Technical Committee ISO/TC 118, , Subcommittee SC 3, Pneumatic tools and
machines.

Introduction
This document is a type C standard as stated in ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
defined in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
requirements of this type C standard take precedence over the requirements of other standards, for machines
that have been designed and built according to the requirements of this type C standard.
The Standard consists of a number of independent parts for individual types of hand-held non-electric power
tools.
Certain parts of the series cover hand-held non-electric power tools, driven by internal combustion engines
powered by gaseous or liquid fuel. In these parts, the safety aspects relating to internal combustion engines
are found in a normative annex.
The parts are type C standards and refer to pertinent Standards of type A and B where such standards are
applicable.
1 Scope
This part of ISO 11148 applies to hand-held non-electric power tools (hereafter referred to as “sanders and
polishers”) intended for polishing and sanding with all types of movement e.g. rotary, orbital and reciprocating,
using coated abrasive products and bonnets of various soft materials and endless belts. The sanders and
polishers may be powered by compressed air, hydraulic fluid or internal combustion engines and intended to
be used by one operator and supported by the operator's hand or hands, with or without a suspension, e.g. a
balancer.
NOTE 1: At the date of publication no sanders and polishers driven by internal combustion engines are known.
This document covers:
⎯ belt sanders;
⎯ orbital sanders;
⎯ polishers;
⎯ random orbital sanders;
⎯ rotary sanders;
⎯ straight line sanders.
NOTE 2: For examples of sanders and polishers see annex B.
This document does not cover:
⎯ special requirements and modifications of sanders and polishers for the purpose of mounting them in
fixtures.
