3 Definitions
3.1.2
Amend the existing text to read as follows:

Where in this standard the expressions “with the aid of a tool”, “without the aid of a tool”, and

“requires the use of a tool”, are used, the word “tool” means a hand tool, for example a

screwdriver, which may be used to operate a screw or other fixing means.

Replace the existing text of the following definitions with the new text as follows:

3.2.3
working voltage
maximum voltage, without the effect of transient voltages, to which the part under
consideration is subjected when the tool is supplied at its rated voltage and operating under
normal load
3.2.9
normal load
load to be applied to a tool at rated voltage or at the upper limit of the rated voltage range, to
obtain rated input or rated current, any marking of short-time or intermittent operation being
observed and, unless otherwise specified, heating elements, if any, being operated as in
normal use
3.3.3
type X attachment
method of attachment of the supply cord so that it can easily be replaced
3.3.4
type Y attachment
method of attachment of the supply cord such that any replacement is intended to be made by
the manufacturer, its service agent or similar qualified person
3.4.1
basic insulation
insulation, not necessarily including insulation used for functional purposes, applied to live
parts to provide basic protection against electric shock
3.4.4
reinforced insulation
insulation of hazardous live parts which provides a degree of protection against electric shock

equivalent to double insulation
NOTE Examples of reinforced insulation are a single layer or several layers which cannot be tested singly as
basic insulation or supplementary insulation.
3.4.5
class I tool
tool in which protection against electric shock does not rely on basic, double or reinforced
insulation only, but which includes an additional safety precaution in that conductive
accessible parts are connected to the protective earthing conductor in the fixed wiring of the
installation in such a way that conductive accessible parts cannot become live in the event of
a failure of the basic insulation. Also considered as class I tools are tools with double
insulation and/or reinforced insulation throughout having an earthing terminal or earthing
contact
– 4 – 60745-1 Amend. 2  IEC:2003(E)

3.4.6
class II tool
tool in which protection against electric shock does not rely on basic insulation only, but in

which additional safety precautions, such as double insulation or reinforced insulation, are

provided, there being no provision for protective earthing or reliance upon installation

conditions
3.4.8
class III tool
tool in which protection against electric shock relies on supply at safety extra-low voltage, and
in which voltages higher than those of safety extra-low voltages are not generated

3.4.10
creepage distance
shortest path between two conductive parts, or between a conductive part and the outer
surface of the enclosure, considered as though metal foil were pressed into contact with
accessible surfaces of insulating material, measured along the surface of the insulating
material
NOTE Examples of creepage distances are given in Annex A.
3.4.11
clearance
shortest distance between two conductive parts, or between a conductive part and the outer
surface of the enclosure, considered as though metal foil were pressed into contact with
accessible surfaces of insulating material, measured through air
NOTE Examples of clearance distances are given in Annex A.
3.5.2
safety extra-low voltage
rated voltage not exceeding 42 V between conductors and between conductors and earth, the
no-load voltage not exceeding 50 V. When safety extra-low voltage is obtained from the
supply mains, it is to be through a safety isolating transformer or a convertor with separate
windings, the insulation of which complies with double or reinforced insulation requirements
3.6.1
hand-held tool (in this standard abbreviated to “tool”)
electric motor-operated or magnetically-driven machine intended to do mechanical work, with
or without provisions for mounting on a support, and so designed that the motor and the
machine form an assembly which can easily be brought to the place of operation, and which is
either held or supported by hand or suspended during operation
NOTE Hand-held tools may be provided with a flexible shaft, the motor being either fixed or portable.

3.8.2
temperature limiter
temperature-sensing device, the operating temperature of which may be either fixed or
adjustable, and which, during normal operation, operates by opening or closing a circuit when
the temperature of the controlled part reaches a predetermined value. It does not make the
reverse operation during the normal duty cycle of the tool
3.8.4
self-resetting thermal cut-out
thermal cut-out which automatically restores the current after the relevant part of the tool has
cooled down to a given value
3.9.2
“off” position of a switching device
stable position in which the related circuit is disconnected from the supply mains
NOTE The “off” position does not imply an all-pole disconnection.

3.9.4
live part
any conductor or conductive part intended to be energized in normal use, including a neutral

conductor but, by convention, not a PEN conductor.

3.10.1
electronic component
part in which conduction is achieved principally by electrons moving through a vacuum, gas or

semiconductor, with the exclusion of neon indicators

3.10.3
protective impedance
impedance connected between live parts and accessible conductive parts, and of value so
that the current is limited to a safe value
3.11.3
short-time operation
operation under normal load for a specified period, starting from cold, the intervals between
each period of operation being sufficient to allow the tool to cool down approximately to
ambient temperature
3.12.2
attachment
device attached to the housing or other component of the tool and which may or may not be
attached to the output mechanism and does not modify the normal use of the tool within the
scope of this standard
Delete definitions 3.9.2 and 3.11.2 and renumber the subsequent definitions accordingly.
Add the following new definition:
3.2.11
normal use
use of a tool for which it is designed, taking into account the manufacturer’s instructions
4 General requirements
