FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

OPTICAL FIBRE CABLES –
Part 6-30: Indoor-outdoor cables –
Family specification for weatherised indoor cables

1 Scope
This part of IEC 60794 is a family specification covering optical fibre indoor cables that are
deployed in short length (≤ 10 m) outdoor environments. These cables generally possess the
characteristics associated with indoor cable designs having the appropriate fire performance
and flexibility that makes them suitable for use in premises. Because of its predicted use
outdoors, stability against environmental attack, for example UV radiation and humidity (see
IEC 60794-6:2020, Table 1), is important. Typical application spaces include the extension of
a short length of indoor cable outside the building such as to a NAP mounted outside the
building at the house wall.

5 Specifications for weatherised indoor cables – Construction
The cable design can be derived from a typical indoor cable design according to the product
specifications described in IEC 60794-2. The specific demand related to UV resistance and
resistance against humidity will require the appropriate selection of the jacket material in
combination with other material and/or design considerations. See Annex A for examples of
weatherised indoor cables.
6 Details of family specifications and test conditions for weatherised indoor
cables
6.1 General
6.1.1 Referenced cable specifications
The specific specifications will depend on the specific design of the indoor cable which was
selected as basis for the design of the weatherised indoor cable. The appropriate family
specifications from IEC 60794-2 (all parts) should be referenced for mechanical
(IEC 60794-2-10:2011, 5.3, IEC 60794-2-20:2013, 4.3, and IEC 60794-2-30:2019, 5.3) and
environmental specifications (IEC 60794-2-10:2011, 5.4, IEC 60794-2-20:2013, 4.4, and
IEC 60794-2-30:2019, 5.4). Additional design characteristics for outdoor exposure to UV
radiation should reference IEC 60794-1-22, method F14. Test methods are defined in the
generic specifications IEC 60794-1-21, IEC 60794-1-22, IEC 60794-1-23 and IEC 60794-1-24.
6.1.2 Test criteria
6.1.3 Applicable tests
The cable types defined in these referenced IEC 60794-2 family specifications are simplex and
duplex cables, multi-fibre cables, and ribbon cables. Family requirements and test conditions
in 6.2 through 6.5 apply to these types, as noted. If no differentiation is stated in the subclause,
they apply to all cable types.
Compliance with the specification shall be verified by carrying out tests selected from Table 1.
It is not intended that all tests in Table 1 be carried out in all cases. The tests to be applied and
the frequency of testing shall be agreed between the customer and supplier.

Alternative high and low temperatures may be agreed between the customer and the
supplier for warmer or colder climates.
Number of cycles: 2, but additional cycles may be required in accordance with particular
customer requirements.
If, due to intended application length, a shorter cable sample is agreed between supplier
and customer, this length shall be sufficient to ensure accurate, repeatable test results as
per the dynamic range and resolution of the optical test equipment.
6.3.2 Water penetration
a) Family specifications
The cable shall not propagate water longitudinally.
b) Test conditions
Method: IEC 60794-1-22, method F5B, method F5C
6.3.3 UV resistance
a) Family specifications
After exposure, the average tensile and elongation of the test specimens from the outer
jacket shall be a minimum of 80 % of the original value.
NOTE This test is also needed when only short parts of the cable are installed with exposure to UV irradiation.
Cable jackets of PE-based materials using a minimum of 2,5 % by weight of carbon black
as colourant may be exempt from UV testing per 6.3.3.
b) .Test conditions
Method: IEC 60794-1-22, method F14
Use method ISO 4892-2 (xenon-arc test) as for outdoor cable testing
Exposure time: 750 h, UV exposure is dependent on the region. Longer exposure times
could be agreed between the customer and supplier.

Since during that test the samples are also sprayed with water to simulate the impact of
humidity on the cable performance, no separate "humidity" test is required to fulfil the
requirements of a weatherised cable defined by Table 1 in IEC 60794-6:2020.
6.3.4 Environmental stress cracking
a) Family specifications
No samples shall be broken after the test.
b) Test conditions
Method: IEC 60811-406 (modifications shall be agreed between the customer and the
manufacturer).
The jacket material is often made of a polymer resin which is highly filled with a flame
retardant additive and thus is more sensitive to stress cracking than the pure polymer (e.g.
PE, PP). Thus, the test shall be adapted to the specific jacket material. Tests shall be agreed
between customer and manufacturer.
6.3.5 Compound flow
a) Family specifications
Unless otherwise specified in the detail specification, the cable specimens shall be permitted
maximum flow quantity of 0,050 g. If the flow quantity from one of the cable specimens
exceeds 0,050 g, but is less than 0,100 g, prepare two additional cable specimens in
accordance with IEC 60794-1-22:2017, 15.2 c), and test as per IEC 60794-1-22:2017, 15.4
