This International Standard applies to composite hollow insulators consisting of a load-bearing insulating tube made of resin impregnated fibres, a housing (outside the insulating tube) made of elastomeric material (for example silicone or ethylene-propylene) and metal fixing devices at the ends of the insulating tube. Composite hollow insulators as defined in this standard are intended for general use (unpressurized) or for use with a permanent gas pressure (pressurized). They are intended for use in both outdoor and indoor electrical equipment operating on alternating current with a rated voltage greater than 1 000 V a.c. and a frequency not greater than 100 Hz or for use in direct current equipment with a rated voltage greater than 1 500 V d.c.
The object of this standard is:
- to define the terms used;
- to prescribe test methods;
- to prescribe acceptance criteria.
Hollow insulators are integrated into electrical equipment which is electrically type tested as required by the applicable equipment standard. So, it is not the object of this standard to prescribe dielectric type tests because the withstand voltages and flashover behaviour are not characteristics of the hollow insulator itself but of the apparatus of which it ultimately forms a part.
All the tests in this standard, apart from the thermal-mechanical test, are performed at normal ambient temperature. This standard does not prescribe tests that may be characteristic of the apparatus of which the hollow insulator ultimately forms a part.
Composite hollow insulators are intended for use in electrical equipment, such as, but not limited to:
- HV circuit-breakers,
- switch-disconnectors,
- disconnectors,
- station posts,
- disconnecting circuit breakers,
- earthing switches,
- instrument- and power transformers,
- bushings,
- cable terminations.
Additional testing defined by the relevant IEC equipment standard may be required.

This International Standard applies to string insulator units of the cap and pin type with
insulating parts of ceramic material or glass, intended for AC overhead lines with a nominal
voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to
insulators of similar design used in substations.
This document applies to string insulator units of the cap and pin type either with ball and
socket couplings or with clevis and tongue couplings.
This document applies to string insulator units for use on overhead lines in clean areas and
polluted areas. For use in areas characterized by very heavy pollution levels and for other
particular or extreme environmental conditions, it may be necessary for certain dimensions to
be changed and insulator units having different creepage distances, spacing and forms may
be preferred (for example, flat profile, hemispherical etc.). Insulators for use on DC systems
may also need different dimensions. In any case, it is applicable that the standardized
mechanical characteristics of this document and coupling sizes are retained.
The object of this document is to prescribe specified values for the mechanical characteristics
and for the main dimensions of string insulator units of the cap and pin type.
The power frequency, lightning impulse and puncture withstand voltages of string insulator
units are not specified in this document. IEC 60383-1 gives the electrical characteristics which
define string insulator units; their values are agreed between purchaser and manufacturer.
Ball and socket couplings are covered by IEC 60120, clevis and tongue couplings by
IEC 60471.

This International Standard is applicable to string insulator units of the long rod type with
insulating parts of ceramic material intended for use in AC overhead power lines with a
nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It is also
applicable to insulators of similar design, used in substations.
This document is applicable to ceramic string insulator units of the long rod type, either with a
clevis end fitting at both ends for coupling with a tongue, or with a socket end fitting at both
ends for coupling with a pin ball.
The object of this document is to prescribe specified values for electrical and mechanical
characteristics, and for the principal dimensions of ceramic string insulator units of the long
rod type.
This document is applicable to string insulator units for use on overhead lines situated in
lightly polluted areas, and the creepage distances given in Table 1 have been established
accordingly, using the IEC TS 60815-2 recommendation of 27,8 mm/kV for SPS class.
However, shorter creepage distances are applicable for use in some non-polluted areas. If
specific operating conditions require or allow non-standard (longer or shorter) creepage
distances, the mechanical characteristics as well as the lengths L (see Clause 4) of this
document are intended to be used unless the need for exceptionally long creepage distances
requires values of L greater than those given in Table 1. In the case of special requirements,
e.g. very heavy polluted areas and for other particular or extreme environmental conditions, it
may be necessary for certain dimensions to be changed.
As far as reasonably applicable, this document is also applicable to be applied to similar
insulator units outside the scope of this standard, such as insulators for electric traction lines.
This document does not include tests on insulators and dimensions of end fittings.
Ball and socket couplings are covered by IEC 60120, clevis and tongue couplings by
IEC 60471.
NOTE 1 For the definition of site pollution severity, see applicable part of IEC TS 60815.
NOTE 2 The term "ceramic" is used in this document to refer to porcelain materials and, contrary to North
American practice, does not include glass.

IEC TR 62039:2021(E) presents the important material properties of polymeric materials used in outdoor insulation and, where applicable, lists standardized test methods including minimum requirements. If no standardized tests are available, the test methods reported in literature are summarized.
This document is valid for insulating materials having polymeric insulation, which are used in outdoor high voltage electrical applications with a system voltage greater than 1 000 V AC and 1 500 V DC (several tests are only defined for alternating current, which are not applicable for direct current). Such applications are relevant where the housing is an integral part of the device, for example in surge arresters and cable terminations. The scope of this document is limited to the insulation materials only and is not generally intended for coating materials (coating materials are, for example, thin layers applied on toughened glass and ceramic). Some tests mentioned in this document are applicable for coating and are under consideration by CIGRE. The performance of insulators in service depends on several factors such as the type of material, the design and environmental conditions. Consequently, the choice of materials that fulfil the requirements listed in Table 1 is a necessary condition but does not guarantee satisfactory performance when used in outdoor insulation.

This international standard is applicable to locking devices used with ball and socket
couplings of string insulator units and used with the corresponding metal fittings standardized
in IEC 60120, when they are supplied separately.
When these locking devices are supplied with an insulator or fitting, they are considered as an
integral part of it. In this case, the relevant test is to be included with those of insulators, as
specified in IEC 60383-1 and IEC 61325. On request, a certificate is to be delivered
confirming that the tests on locking devices as specified in this document have been carried
out. The locking devices are usually supplied with the insulator or corresponding metal fittings.
The object of this document is
• to define the shapes and some standard dimensions for locking devices,
• to define the test methods for locking devices,
• to state the acceptance conditions for supply,
• to give other dimensions for guidance of manufacturing only.
The object of this document does not include the specification of the nature of the material,
and the material covered by the scope of this document does not have a surface coating for
corrosion protection. However, the material which will give rise to significant contact
corrosion(chemical reaction) between the locking device and the ball and socket coupling
does not covered by this document.

This document is applicable to composite line post insulators for AC overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to line post insulators of similar design used in substations or on electric traction lines. This document applies to line post insulators of composite type, generally with metallic couplings, with and without a base plate. It also applies to such insulators when used in complex structures. It does not apply to hollow insulators adapted for use as line post insulators. The object of this document is to specify the main dimensions of the couplings to be used on the composite line post insulators in order to permit the assembly of insulators or fittings supplied by different manufacturers and to allow, whenever practical, interchangeability with existing installations. It also specifies a standard designation system for composite line post insulators.

IEC 62772:2016 applies to composite hollow core station post insulators consisting of a load-bearing insulating tube (core) made of resin impregnated fibres an insulating filler material (e.g. solid, liquid, foam, gaseous pressurized or unpressurized), a housing (outside the insulating tube) made of polymeric material (for example silicone or ethylene-propylene) and metal fixing devices at the ends of the insulating tube. Composite hollow core station post insulators as defined in this standard are intended for general use in substations in both, outdoor and indoor environments, operating with a rated AC voltage greater than 1 000 V and a frequency not greater than 100 Hz or for use in direct current systems with a rated voltage greater than 1 500 V. The object of this standard is: - to define the terms used; - to prescribe test methods; - to prescribe acceptance criteria. All the tests in this standard, apart from the thermal-mechanical test, are performed at normal ambient temperature. This standard does not prescribe tests that may be characteristic of the apparatus of which the composite hollow core station post insulator ultimately may form a part.

IEC 62688:2017 describes the fundamental construction and testing requirements for Concentrator Photovoltaic (CPV) modules and assemblies in order to provide safe electrical and mechanical operation during their expected lifetime. Specific topics are provided to assess the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses. This document attempts to define the basic requirements for various application classes of concentrator photovoltaic modules and assemblies, but does not encompass all national and regional codes. This document is designed so that its test sequence can coordinate with those of IEC 62108, so that a single set of samples may be used to perform both the safety and performance evaluation of a CPV module and assembly.

In some cases, it has been necessary to include in an IEV part a concept taken from another
IEV part, or from another authoritative terminology document (VIM, ISO/IEC 2382, etc.), in
both cases with or without modification to the definition (and possibly to the term).
This is indicated by the mention of this source, printed in lightface, and placed between
square brackets at the end of the definition.
Example: [131-03-13 MOD]
(MOD indicates that the definition has been modified)
Terms in additional IEV languages
These terms are placed at the end of the entry, on separate lines (one single line for each
language), preceded by the alpha-2 code for the language defined in ISO 639, and in the
alphabetic order of this code. Synonyms are separated by semicolons.
