Overview
IEC TR 62362:2020 - "Selection of optical fibre cable specifications relative to mechanical, ingress, climatic or electromagnetic characteristics - Guidance" is a Technical Report from the IEC that provides practical guidance for specifying optical fibre cables using the MICE classification (Mechanical, Ingress, Climatic and Chemical or Electromagnetic). This second edition (2020) supersedes the 2010 edition and updates references to the current cabling framework and fibre designations.
Key updates include:
- Replacement of older references with ISO/IEC 11801-1 as the source for MICE classification.
- An updated MICE table (Annex A) describing attribute severities.
- Updated optical fibre designations per IEC 60793-2-10 and IEC 60793-2-50.
Key topics and technical content
IEC TR 62362:2020 focuses on matching cable performance to environmental and installation stresses. Major technical topics covered:
- MICE classification: severity levels (subscripts 1–3) for mechanical, ingress, climatic and electromagnetic risks.
- Mechanical attributes: shock/bump, vibration, tensile force, crush, impact, bending/flexing/torsion.
- Ingress attributes: particulate ingress, water immersion and related protection requirements.
- Climatic and chemical attributes: ambient temperature, temperature change rate, humidity, solar radiation, liquid and gaseous pollution.
- Electromagnetic considerations: guidance where EMI/RFI may affect cable installations.
- Standards mapping and hierarchy: relationship between generic, sectional, family and product specifications; references to IEC 60794 series (cable tests) and IEC 60793 series (fibre specifications).
- Annexes: Annex A (MICE details), Annex B (IEC optical fibre cable standards), Annex C (fibre specifications and tests).
Note: this TR provides guidance and explanation rather than prescriptive requirements - it helps interpret and apply the normative cable standards (e.g., IEC 60794 parts).

INTRODUCTION
Optical fibre cable specification standards are defined in IEC 60794 (all parts), which are
listed in Annex B. They are organized in a hierarchy similar to the IECQ system. They differ
from the IECQ system in that they are all performance standards. Optical fibre cable
standards specify the attributes and tests on cables intended to verify adequate protection of
fibres against external influences during the cabling process, cable installation handling and
from environmental effects during storage and operation. The attributes of the fibres within
the cable are defined by reference to optical fibre specification standards of the IEC 60793
series, which are listed in Annex C. A complete and up-to-date listing of standards in the
IEC 60793 and IEC 60794 series is available on the IEC website: http://www.iec.ch.
The different levels of hierarchy are: generic, sectional, family and product. The primary
distinction between these is the level of detail. Typically, more options or wider ranges are
present at the higher level. At a given level, the distinctions are with respect to application or
cable construction. Clause 2 of this document gives a more complete mapping. Parts of the
family specification include blank detail specifications for various attributes that do not have
normative requirements.
At the sectional specification level, the main categories are indoor cables, outdoor cables,
cables along overhead lines, microduct cabling and indoor/outdoor cables. Typically, the
outdoor cables have tougher tests than the indoor cables. At the product specification level,
there is a series of standards intended to support ISO/IEC 11801 (all parts) for premises
cabling, using both indoor and outdoor varieties.
It is not the intention of this document to reproduce the requirements of all relevant
specifications, but rather to discuss typical application situations and mention key options for
tests, while seeking to guarantee the performance of cables in operation.

4 MICE attributes and severities
4.1 General
The MICE classification system has three levels of severity:
1) M I C E describes a typical environment such as that assumed in ISO/IEC 11801-2; (i.e.
1 1 1 1
office premises, etc.);
2) M I C E describes a light industrial environment;
2 2 2 2
3) M I C E describes a harsh industrial environment.
3 3 3 3
See Annex A for a more detailed description of the MICE severity levels.
4.2 Mechanical
4.2.1 Shock/bump
Shock and bump are not specified for optical fibre cables. They are inherently robust in this
respect.
4.2.2 Vibration
Vibration in the industrial premises (as opposed to wind induced vibration on aerially deployed
cables) is not specified for optical fibre cables. They are inherently robust in this respect.
4.2.3 Tensile force
For outdoor cables specified in IEC 60794-3 (all parts), manufacturers specify a rated tensile
force. The requirement is that the fibre shall not exceed a percentage of the proof test strain
(to be agreed between customer and supplier) when the cable is tested at the rated load.
For indoor cables, the different family specifications of IEC 60794-2 (all parts) have different
requirements on the tensile load ranging from 70 N to 400 N.
4.2.4 Crush
For optical fibre cables, the crushing force is applied in a plate to plate test.
For indoor cables, crush is specified at 500 N. For outdoor cables, different levels are
specified depending on whether the cable is armoured or not. For unarmoured cable, values
of between 750 N and 1 500 N are specified. For armoured cable, values between 1 100 N
and 2 200 N are specified.
4.2.5 Impact
For indoor cables, a value of 1 J and a hammer with a striking surface of 12,5 mm radius are
specified. For un-armoured outdoor cables, a value of 10 J and a hammer with a striking
surface of 300 mm radius are specified.
4.2.6 Bending, flexing and torsion
All the family specifications have requirements on these attributes.
For bending, there are multiple tests such as bending under tension, repeated bending and
simple bending. The bending diameter is typically 20 times the cable diameter.
For flexing, the bending diameter is typically 20 times the cable diameter, with 25 cycles
typically applied.
– 8 – IEC TR 62362:2020 © IEC 2020
For torsion, the test length, load, and number of turns varies depending on the family
specification. For indoor cables, the length is 125 x cable diameter or 250 mm, loaded at 20 N
with 10 or 20 cycles (per detailed specification) applied.
4.3 Ingress
4.3.1 Basic consideration
Optical fibre cables come in a variety of constructions. Some examples are slotted core, loose
tube, tight buffered. The slotted core and loose tube can be filled or unfilled. These different
constructions have different ingress characteristics.
4.3.2 Particulate ingress
Particulate ingress is not specified for optical fibre cables. They are inherently robust in this
respect.
4.3.3 Water immersion
On cables for which water immersion is specified, the test is different from that found in Annex
A. The requirement is that a pressure equivalent to 1 m of water is applied at or near one end
of a short (< 3 m) cable. After 24 h, no water shall be found at the other end.
It is expected that cables passing this test would pass both I and I severities.
2 3
4.4 Climatic
4.4.1 General
Terminations such as cable closures are generally considered separately from the cables and
are covered by standards from the IEC 61753 series prepared by IEC SC 86B.

INTRODUCTION
Optical fibre cable specification standards are defined in IEC 60794 (all parts), which are
listed in Annex B. They are organized in a hierarchy similar to the IECQ system. They differ
from the IECQ system in that they are all performance standards. Optical fibre cable
standards mainly cover the attributes and tests that protect the fibre from the environment,
including installation, and the fibre attributes that may be affected by cabling. Optical fibre
cable standards specify the attributes and tests on cables intended to verify adequate
protection of fibres against external influences during the cabling process, cable installation
handling and from environmental effects during storage and operation. The attributes of the
fibres within the cable are defined by reference to optical fibre specification standards of the
IEC 60793 series, which are listed in Annex C. A complete and up-to-date listing of standards
in the IEC 60793 and IEC 60794 series is available on the IEC website: http://www.iec.ch.
The different levels of hierarchy are: general generic, sectional, family and product. The
primary distinction between these is the level of detail. Typically, more options or wider
ranges are present at the higher level. At a given level, the distinctions are with respect to
application or cable construction. The references section Clause 2 of this document gives a
more complete mapping. Parts of the family specification include blank detail specifications
for various attributes that do not have normative requirements.
At the sectional specification level, two main categories are indoor and outdoor cables.
Typically the outdoor cables have tougher tests than the indoor cables. At the product
specification level, there are series of standards intended to support ISO/IEC 11801 for
premises cabling, using both indoor and outdoor varieties.
This guidance will not attempt to reproduce the requirements of all the different specifications.
For each of the MICE attributes, it will discuss the situation and mention the key options.
At the sectional specification level, the main categories are indoor cables, outdoor cables,
cables along overhead lines, microduct cabling and indoor/outdoor cables. Typically, the
outdoor cables have tougher tests than the indoor cables. At the product specification level,
there is a series of standards intended to support ISO/IEC 11801 (all parts) for premises
cabling, using both indoor and outdoor varieties.
It is not the intention of this document to reproduce the requirements of all relevant
specifications, but rather to discuss typical application situations and mention key options for
tests, while seeking to guarantee the performance of cables in operation.

SELECTION OF OPTICAL FIBRE CABLE SPECIFICATIONS
RELATIVE TO MECHANICAL, INGRESS, CLIMATIC OR
ELECTROMAGNETIC CHARACTERISTICS – GUIDANCE
1 Scope
The purpose of this document is to provide information on the specification of optical fibre
cables with respect to the mechanical, ingress, climatic and chemical or electromagnetic
characteristics (MICE) as classified in ISO/IEC 24702 ISO/IEC 11801-1.
In this classification system, each letter of the four initials of the acronym are subscripted with
a value from one to three to indicate different severities. The current attributes and severities
are found in Annex A.

4 MICE attributes and severities
4.1 General
The MICE classification system has three levels of severity:
1) M I C E describes a typical environment such as that assumed in ISO/IEC 11801-2; (i.e.
1 1 1 1
office premises, etc.);
2) M I C E describes a worst-case light industrial environment;
2 2 2 2
3) M I C E describes a worst-case harsh industrial environment.
3 3 3 3
See Annex A for a more detailed description of the MICE severity levels.
4.2 Mechanical
4.2.1 Shock/bump
Shock and bump are not specified for optical fibre cables. They are inherently robust in this
respect. A more important attribute is bending.
4.2.2 Vibration
Vibration in the industrial premises (as opposed to wind induced vibration on aerially deployed
cables) is not specified for optical fibre cables. They are inherently robust in this respect.
4.2.3 Tensile force
For outdoor premises cables specified in IEC 60794-3 (all parts), manufacturers specify a
rated tensile force. The requirement is that the fibre shall not exceed a percentage of the
proof test strain (to be agreed between customer and supplier) when the cable is tested at the
rated load.
For indoor cables, the different family specifications of IEC 60794-2 (all parts) have different
requirements on the tensile load ranging from 70 N to 400 N.
4.2.4 Crush
For optical fibre cables, the crushing force is applied in a plate to plate test.
For indoor cables, crush is specified at 500 N. For outdoor cables, different levels are
specified depending on whether the cable is armoured or not. For unarmoured cable, values
of between 1 500 N and 3 000 N may be specified. For armoured cable, values between
2 200 N and 10 000 N may be specified. For unarmoured cable, values of between 750 N and
1 500 N are specified. For armoured cable, values between 1 100 N and 2 200 N are
specified.
4.2.5 Impact
For indoor cables, a value of 1 J and a hammer with a striking surface of 12,5 mm radius is
are specified. For un-armoured outdoor cables, a value of either 10 J and a hammer with a
striking surface of 300 mm radius or 3 J with a 10 mm radius is are specified.
4.2.6 Bending, flexing and torsion
All the family specifications have requirements on these attributes.
For bending, there are multiple tests such as bending under tension, repeated bending and
simple bending. The bending diameter is typically 20 times the cable diameter.
– 8 – IEC TR 62362:2020 RLV © IEC 2020
For flexing, the bending diameter is typically 20 times the cable diameter, with 25 cycles
typically applied.
For torsion, the test length, load, and number of turns varies depending on the family
specification. For indoor cables, the length is from 250 mm to 1 000 mm, loaded at 20 N with
20 cycles applied 125 x cable diameter or 250 mm, loaded at 20 N with 10 or 20 cycles (per
detailed specification) applied.
4.3 Ingress
4.3.1 Basic consideration
Optical fibre cables come in a variety of constructions. Some examples are slotted core, loose
tube, tight buffered. The slotted core and loose tube can be filled or unfilled. These different
constructions have different ingress characteristics.
4.3.2 Particulate ingress
Particulate ingress is not specified for optical fibre cables. They are inherently robust in this
respect.
4.3.3 Water immersion
On cables for which water immersion is specified, the test is different from that found in Annex
A. The requirement is that a pressure equivalent to 1 m of water is applied at or near one end
of a short (< 3 m) cable. After 24 h, the requirement is: no water shall be found at the other
end.
It is expected that cables passing this test would pass both I and I severities.
2 3
4.4 Climatic
4.4.1 General
Terminations such as cable closures are generally considered separately from the cables and
are covered by standards from the IEC 61753 series prepared by IEC SC 86B.
NOTE The values that appear in Table 1 to Table 3 below indicate levels of resistance to climatic phenomena.
Values of 1 to 3 correspond to the relevant level of severity in the MICE classification system. A value of 0
indicates no effective resistance to the climatic phenomena described.
4.4.2 Ambient temperature
The different specifications allow different ranges of values to be specified by the customer,
depending on the climate in which the cable will be installed. For the detailed specifications
for premises cabling, –20 °C to +60 °C are specified. Other ranges and combinations from
–45 °C to +70 °C are also found as options in the family specifications.
4.4.3 Rate of change of temperature
This is not specified. All the cables that pass the other requirements will, however, have the
capability of 3 °C/min. The rate of change of temperature is not specified in the product
specifications of cables. IEC 60794-1-22, methods F1 and F12, specify a rate of heating that
shall not exceed 60 °C per hour. However, it is assumed that all the cables have the capability
of 3 °C/min.
4.4.4 Humidity
For further study.
4.4.5 Solar radiation
Resistance to solar radiation in the industrial premises environment is not specified in the
product specifications of cables. Resistance to solar radiation is a property of the sheath
material. The severities associated with some common generic materials are indicated in
Table 1.
A specific grade of the generic material may have a different performance to that identified in
Table 1.

4.5 Electromagnetic
Cables can be dielectric, or can contain metallic elements such as armour, strength members
or sheaths. With the exception of possible damage on cables with metallic sheathes due to
lightning strikes, optical fibre cables are immune to all of the attributes for this category.

C.1 Specifications
The fibre specifications are organized as a series of sectional specification standards beneath
a general specification. Within each sectional specification, there is a series of normative
annexes that define the requirements for the different family specifications. Within the single-
mode fibre sectional specification, IEC 60793-2-50, for example, are the family specifications
for the B1.1, B1.2, B1.3, B2, B4, B5 and B6 B-652.B, B-652.D, B-653, B-654, B-655 and B-
