IEC 61032:1997 pdf download – Protection of persons and equipment by enclosures – Probes for verification.
IEC 61032 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 g.ven 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 P code probe is for some reason
NOTE I — The selection 01 a test probe br a particuiar purpose is the responsibilily 01 the relevant technical Corn Inhttees.
NOTE 2 — Technical committees wishing to develop new probes or to moddi, evicting probes should ubmiI proposals to technical committee 70 Ia, amendment at 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.

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 [1EV 826-03-12]
NOTE — This definition taken from the International Electrotechnical Vocabulary (1EV) needs the following additional explanations:
a) Enclosures provide protection of persons or livestock against access to hazardous parts.
b) Bamers, 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.
