Overview
EN IEC 60794-1-305:2023 (IEC 60794-1-305) defines Method G5 - Ribbon tear (separability) for optical fibre ribbons used as cable elements. The standard sets a uniform test procedure to assess the mechanical property of tear resistance and separability for edge-bonded and encapsulated fibre ribbons used in telecommunication optical fibre cables (including cables with combined electrical conductors). The test is intended to verify that ribbons can be torn by hand where required, or that they resist tearing where fibre separability is not needed, without damaging fibre coatings.
Key topics and requirements
- Purpose: Ensure sufficient ribbon tear resistance or fibre separability so fibres can be separated without coating damage.
- Applicability: Edge-bonded ribbons and encapsulated ribbons specified in IEC 60794-1-31. Not intended for partially-bonded ribbons.
- Sample size and layout:
- Typically 3 to 5 samples selected from the ribbon(s) under test.
- For an n‑fibre ribbon, n/2 specimens are taken from each sample.
- Each specimen: minimum 100 mm length.
- Specimen preparation:
- Prepare increasing units to be separated (fibre 1; fibres 1–2; fibres 1–3; … up to n/2).
- Fibres to be separated are cut/separated with a knife or suitable method; provide ≥30 mm length for clamping.
- Test objective: Tear the ribbon by hand (or follow the specified procedure) to evaluate separability without damaging coatings.
- Reporting: Document sample details, procedure parameters and pass/fail results as specified in the standard.
Applications and users
This test method is practical for:
- Cable manufacturers performing quality control and production verification of optical fibre ribbons.
- Independent test laboratories conducting type approval, acceptance testing and failure analysis.
- Network operators and system integrators specifying mechanical separability requirements in procurement and installation guides.
- R&D teams developing ribbon designs to meet separability or tear-resistance performance targets.
Practical uses include design validation, routine production tests, incoming inspection, and ensuring safe field separation of fibres during cable termination or splicing.

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
interes
