IEC 60794-3-12 pdf – Optical fibre cables – Part 3-12: Outdoor cables – Detailed specification for duct and directly buried optical telecommunication cables for use in premises cabling
1 Scope
This part of IEC 60794 is a detailed specification for duct and directly buried opticaltelecommunication cables for use in premises cabling toensure compatibilitywithISO/IEC 11801-1.This document’s requirements ensure that the isonIEC 11801-1 models work
for generic cabling and system performances. Values in this document support these models.
The requirements of the family specification lEC 60794-3-10 are applicable to cables covered
by this document. Particular requirements detailed in Clause 5 either define a specific optionrelative to the requirements of lEC60794-3-10 or define additional requirements.

4General requirements
The cable shall comply with the family specification, IEC 60794-3-10, and meet therequirements which are defined in it,including requirements in the sectional specification,IEC 60794-3. Particular requirements detailed in’Clause 5 are optional,relative to therequirements of lEC 60794-3-10, or define additional requirements.
The optical fibre contained in cables covered by this document shall comply with one of thefollowing standards, and meet the normative requirements defined within them as applicable:
.lEC 60793-2-50:2018,Annex A
(single-mode B-652.D fibre sub-category);
. IEC 60793-2-50:2018,Annex F
(single-mode B-657 fibres);
·IEC 60793-2-10:2019,Annex A
(multimode fibre sub-categories A1-OM3，A1-OM4 and
A1-OM5).
To ensure compatibility with the ISO/IEC 11801 series, optical performance level requirements
are presented in terms of the performance classification codes for cabled optical fibre asfollows:
. oS1a:single-mode fibre, sub-categories B-652.D or B-657;. OS2:single-mode fibre,sub-categories B-652.D or B-657;OM3: multimode fibre sub-category A1-OM3;
.OM4: multimode fibre sub-category A1-OM4;.OM5: multimode fibre sub-categoryA1-OM5.
NOTE These codes are informative from the perspective of the requirements defined in this document.The oS1,OM1 and 0M2performance classification codes for cabled optical fibre are no longer normative inISOVIEC 11801(Parts 1 through 6). See ISOIEC 11801-1:2017,Annex F, for more information.
5 Particular requirements
5.1 General
These requirements either define a specific option relative to the requirements ofIEC 60794 -3-10 or define additional requirements.
5.2MICE(mechanical, ingress,climatic and chemical and electromagnetic)
characteristics
Cables intended for installation in conformity with ISOIEC 11801-1 and related standards may
require the specification of additionaltests to ensure their suitability in the applicableenvironments defined by the mechanical，ingress,climatic and chemical and electromagnetic(MICE) classification. Such tests are outside the scope of lEC 60794 cable specifications, and
MICE criteria are not part of the requirements for IEC 60794 specifications. The MICEtestsmay be the same as, similar to, or substantially different from, the tests required by lEC 60794
specifications,specifically those in lEC 60794-1-21,IEC 60794-1-22 and’ IEC 60794-1-23.Cables manufactured per IEc 60794 specifications, may or may not meet the MIlCE criteria.For
