Overview

IEC 60811-302:2012 is an international standard published by the International Electrotechnical Commission (IEC) that specifies test methods for measuring the direct current (d.c.) resistivity of filling compounds used in electric and optical fibre cables. This standard outlines the procedure to accurately determine the d.c. resistivity at two critical temperatures-23 °C and 100 °C-ensuring the reliability and performance of non-metallic filling compounds typically employed in communication and optical fibre cables.

This part of the IEC 60811 series replaces the withdrawn Clause 10 of IEC 60811-5-1:1990 without technical changes and is intended to be used alongside IEC 60811-100:2012 for general test procedures. The standard follows the test method described in IEC 60247, emphasizing precise sample preparation, controlled aging, and standardized measurement conditions.

Key Topics

  • Scope and Application
    Defines the test method for d.c. resistivity measurement of filling compounds in cables at specified temperatures, focusing on communication and optical fibre cable materials.

  • Test Methodology
    Utilizes a three-terminal cell apparatus as described in IEC 60247 to perform electrical tests on filling compounds. Samples are heated to their clarity point before being poured into a preheated cell to avoid air bubble contamination.

  • Temperature Conditions
    Tests are conducted at controlled temperatures of 23 ± 2 °C and 100 ± 3 °C, simulating normal and elevated operational environments where cable filling compounds must maintain electrical integrity.

  • Ageing Procedure
    The aging conditions follow IEC 60247 to evaluate the stability and performance of the filling compounds over time and temperature exposure.

  • Measurement and Reporting
    The d.c. resistivity is measured under a 100 V test voltage. The results are calculated and expressed as per IEC 60247 guidelines, with detailed test reporting following IEC 60811-100 requirements.

  • Normative References
    Incorporates related IEC standards such as IEC 60247 for insulating liquid testing and IEC 60811-100 for general test methods for non-metallic cable materials, ensuring coherence across testing practices.

Applications

IEC 60811-302:2012 serves as a fundamental guideline for manufacturers, quality control laboratories, and testing facilities engaged in the production and certification of electric and optical fibre cables. Its practical applications include:

  • Quality Assurance
    Ensuring the electrical properties of filling compounds meet stringent resistivity requirements to prevent electrical faults and maintain cable performance.

  • Material Selection and Development
    Assisting material developers and manufacturers in evaluating and optimizing filling compounds based on their resistivity at operational temperatures.

  • Compliance and Standardization
    Providing a standardized testing approach to facilitate international compliance and interoperability in cable manufacturing and certification processes.

  • Reliability in Harsh Environments
    Validating performance under elevated temperatures (100 °C), critical for cables used in demanding industrial, offshore, and communication installations.

Related Standards

  • IEC 60811-100:2012 – General test methods for non-metallic materials in electric and optical fibre cables; foundational for all parts of IEC 60811 series.

  • IEC 60247 – Specifies the measurement of relative permittivity, dielectric dissipation factor (tan δ), and d.c. resistivity of insulating liquids, forming the basis for the test method in IEC 60811-302.

  • IEC 60811 Series – A comprehensive collection of standards detailing test methods for non-metallic materials used in cable construction, covering insulation, sheathing, bedding, and filling compounds.

  • IEC 60811-5-1:1990 (Withdrawn) – Previously contained Clause 10 on d.c. resistivity measurement; replaced by IEC 60811-302.


By adhering to IEC 60811-302:2012, stakeholders in the cable manufacturing industry ensure accurate assessment of filling compounds' electrical properties, facilitating safer, efficient, and standardized cable production worldwide.

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.

INTRODUCTION
The IEC 60811 series specifies the test methods to be used for testing non-metallic materials
of all types of cables. These test methods are intended to be referenced in standards for
cable construction and for cable materials.
NOTE 1 Non-metallic materials are typically used for insulating, sheathing, bedding, filling or taping within cables.
NOTE 2 These test methods are accepted as basic and fundamental and have been developed and used over
many years, principally for the materials in all energy cables. They have also been widely accepted and used for
other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore
applications.
