PROTECTION OF PERSONS AND EQUIPMENT BY ENCLOSURES –
PROBES FOR VERIFICATION
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61032 has been prepared by IEC technical committee 70: Degrees
of protection by enclosures.
This second edition cancels and replaces the first edition published in 1990 and constitutes a
technical revision.
It has the status of a basic safety publication in accordance with IEC Guide 104.
The text of this standard is based on the following documents:
FDIS Report on voting
70/82/FDIS 70/85/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annexes A and B are for information only.
The contents of the corrigendum of January 2003 have been included in this copy.

PROTECTION OF PERSONS AND EQUIPMENT BY ENCLOSURES –
PROBES FOR VERIFICATION
1 General
1.1 Scope and object
This International Standard specifies details and dimensions of test probes intended to verify
the protection provided by enclosures with regard to:
– protection of persons against access to hazardous parts inside the enclosure;
– protection of the equipment inside the enclosure against ingress of solid foreign objects.
The object of this International Standard is:
– to bring together in one publication object probes and access probes currently specified in
other standards, together with any necessary new probes;
– to guide technical committees in the selection of test probes;
– to encourage those concerned to specify test probes in accordance with those already
specified in this International Standard rather than modify details and dimensions;
– to limit the further proliferation of types of test probe.
1.2 General recommendations
When selecting probes, priority should be given to IP code probes.
The use of other probes, particularly probes which are not specified in this International
Standard, should be limited to cases where the use of an IP code probe is for some reason
impractical.
NOTE 1 – The selection of a test probe for a particular purpose is the responsibility of the relevant technical
committees.
NOTE 2 – Technical committees wishing to develop new probes or to modify existing probes should submit
proposals to technical committee 70 for amendment of this standard.
Application of the probes, test conditions, acceptance conditions and the procedure in case of
conflicting test results are the responsibility of the relevant product committee.
Certificates based on test probes conforming to the first edition of IEC 61032 should remain
valid.

2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. At the time of publication, the editions
indicated were valid. All normative documents are subject to revision, and 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. Members of
IEC and ISO maintain registers of currently valid International Standards.
IEC 60050(826): 1982, International Electrotechnical Vocabulary (IEV) – Chapter 826: Electrical
installations of buildings
IEC 60529: 1989, Degrees of protection provided by enclosures (IP Code)
IEC 60536: 1976, Classification of electrical and electronic equipment with regard to protection
against electric shock
ISO 4287-1: 1984, Surface roughness – Terminology – Part 1: Surface and its parameters
3 Definitions
For the purpose of this International Standard the following definitions apply:
3.1 Enclosure
A part providing protection of equipment against certain external influences and, in any
direction, protection against direct contact [IEV 826-03-12]
NOTE – This definition taken from the International Electrotechnical Vocabulary (IEV) needs the following additional
explanations:
a) Enclosures provide protection of persons or livestock against access to hazardous parts.
b) Barriers, shapes of openings or any other means – whether attached to the enclosure or formed by the
enclosed equipment – suitable to prevent or limit the penetration of the specified test probes are considered as
a part of the enclosure, except when they can be removed without the use of a key or tool.
(see 3.1 of IEC 60529).
3.2 Hazardous part
A part that is hazardous to approach or touch (see 3.5 of IEC 60529).
3.2.1 Hazardous live part
A live-part which, under certain conditions of external influences, can give an electric shock
(see 3.5.1 of IEC 60529).
3.2.2 Hazardous mechanical part
A moving part, other than a smooth rotating shaft, that is hazardous to touch (see 3.5.2
of IEC 60529).
3.2.3 Hazardous hot or glowing part
A hot or glowing part that is hazardous to touch.

3.3 Access probe
A test probe simulating in a conventional manner a part of a person or a tool, or the like, held
by a person to verify adequate clearance from hazardous parts (see 3.8 of IEC 60529).
3.4 Object probe
A test probe simulating a solid foreign object to verify the possibility of ingress into an
enclosure (see 3.9 of IEC 60529).
3.5 IP code probe
A test probe to verify the degrees of protection specified in IEC 60529.
3.6 Other probe
A test probe, different from IP code probes.
3.7 Adequate clearance for protection against access to hazardous parts
A distance to prevent contact or approach of an access probe to a hazardous part (see 3.7
of IEC 60529).
NOTE – The requirements to verify adequate clearance are specified in IEC 60529.
4 Classification of test probes
Test probes are classified as follows:
a) according to their designation
– IP code probes;
– other probes;
b) according to the kind of protection they are intended to check
– access probes;
– object probes;
c) according to the specific hazard they are intended to check
– probes mainly intended to be used to verify the protection of persons against access to
hazardous live parts or hazardous mechanical parts;
– probes specifically intended to be used to verify the protection of persons against access
to hazardous mechanical parts;
– probes mainly intended to be used to verify the protection of persons against access to
internal parts involving thermal hazard, for instance internal hot or glowing parts;
– probes intended to be used to verify the protection of equipment against ingress of solid
foreign objects.
