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 die grinder 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 source.
Principles for designing die grinders with reduced noise emission are contained in ISO/TR 11688-1 and
ISO/TR 11688-2.
The noise emission from using die grinders has three main sources:
 the die grinder 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 die grinder.

SIST EN ISO 11148-9:2012
ISO 11148-9:2011(E)
Typical sources of noise emitted by the die grinder 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.
Alternatively, where practicable, the exhaust air or gases may be piped away from the operator in a hose.
Vibration-induced noise can often be reduced by vibration isolation and damping.
This list is not exhaustive; where alternative technical measures for noise reduction, with greater efficiency,
are available, they should be used by the manufacturer.
4.5 Vibration
The die grinder shall be designed and constructed so that the vibration is reduced to the lowest level at the
handles and at any other parts of the tool in contact with the operator's hands, taking account of technical
progress and the availability of means of reducing vibration, in particular at source. Principles for designing die
grinders with reduced vibration emission are contained in CR 1030-1.
Typical sources of vibration emitted by a die grinder are
 imbalance of rotating parts,
 poorly designed motors and gears, and
 resonances in the structure of the machine, particularly the handles and their mounts.
The following design features have been found to be effective and should be considered by manufacturers
when designing die grinders:
a) autobalancers;
b) increasing inertia;
c) isolated casing or handles.
This list is not exhaustive; where alternative technical measures for vibration reduction, with greater efficiency,
are available, they should be used by the manufacturer.
4.6 Materials and substances processed, used or exhausted
4.6.1 Exhaust air or gas
Pneumatic die grinders driven with compressed air or gas shall be designed in such a way that exhaust

Introduction
This International Standard 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 standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of other standards, for machines that
have been designed and built according to the provisions 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.

Part 9:
Die grinders
1 Scope
This part of ISO 11148 applies to hand-held non-electric power tools fitted with collets (hereafter referred to as
“die grinders”) intended for grinding and surface finishing and chamfering using mounted points, burrs and
files and small wire brushes and other accessories mounted on shanks. The die grinders 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.
NOTE1: At the date of publication no die grinders driven by internal combustion engines are known. When these are
identified the standard will be amended to include such power tools.
This document covers:
⎯ - angle die grinders;
⎯ - reciprocating files;
⎯ - rotary files;
⎯ - straight die grinders.
NOTE For examples of die grinders see annex B.
NOTE Grinders without collets for use with cones and plugs with threaded inserts are covered by part 7.
This document deals with all significant hazards, hazardous situations or hazardous events with the exception
of the use of die grinders in potentially explosive atmospheres, when they are used as intended and under
conditions of misuse which are reasonably foreseeable by the manufacturer.
NOTE EN 13463-1 gives requirements for non-electrical equipment for potentially explosive atmospheres.

4 Safety requirements and measures
4.1 General
The machine shall comply with the following safety requirements and/or protective measures and be verified
according to clause 5. In addition, the machine shall be designed according to the principles of ISO 12100 part
1 and 2 for hazards relevant but not significant, which are dealt with by this document.
The measures adopted to comply with the requirements of this clause shall take account of the state-of-the-art.
NOTE: It is recognised that optimising the design in respect of some safety measures may result in a degradation of
performance against other safety requirements. In such cases a balance should be struck between the various
requirements in order to achieve a die grinder 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 die grinders, except the insert tool, shall not have sharp edges or angles or rough or
abrasive surfaces, see ISO 12100-2:2003, 4.
