Overview
IEC 61196-1-308:2012 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies mechanical test methods for copper-clad metals used in coaxial communication cables. This standard focuses on testing the tensile strength and elongation at fracture for both annealed and hard-drawn solid copper-clad metals, which serve as inner conductors in coaxial cables. The second edition, published in 2012, supersedes the 2005 edition, introducing more precise requirements and specific test methods that differentiate between annealed and hard-drawn copper-clad conductors.
Adhering to IEC 61196-1-308:2012 ensures reliable mechanical performance of copper-clad metals in coaxial cables, facilitating durability and longevity in communication systems. This standard supports manufacturers, testing laboratories, and quality assurance personnel in validating cable conductor materials to meet required mechanical properties.
Key Topics
Scope
Applies to coaxial communication cables and defines procedures for testing tensile strength and percentage elongation at fracture for annealed and hard-drawn solid copper-clad metals used as inner conductors.Test Principles
The core test involves applying tensile force to a standardized test specimen at ambient temperature (between 10 °C and 35 °C) to measure the maximum tensile force and elongation at fracture.Test Equipment and Accuracy
High-precision force-measuring machines with an error margin of less than 1% and extensometers capable of measuring elongation over a gauge length of 250 mm with resolutions better than 0.25 mm are required.Specimen Preparation
Test specimens should have an original gauge length of 250 mm and a total length around 300 mm. Specimens must be straightened before testing to ensure accuracy.Test Procedure
- Measure the original cross-sectional area of the specimen using two diameter measurements taken 90° apart.
- Load the specimen incrementally to 10% of its minimum breaking load.
- Apply tensile load at controlled rates: no more than 25 mm/min for hard-drawn metals and 300 mm/min for annealed metals.
- Record the maximum tensile force and elongation at fracture, discarding tests where fracture occurs near clamping jaws.
Result Expressions
- Tensile Strength (Rₘ) = Maximum force (Fₘ) divided by the original cross-sectional area (S₀), expressed in N/mm².
- Percentage Elongation at Fracture (Aₜ) = ((Gauge length at fracture Lₜ - Original gauge length L₀) / Original gauge length L₀) × 100%.
Requirements
Tensile strength and elongation values must comply with the parameters defined in the relevant coaxial cable specifications.
Applications
IEC 61196-1-308:2012 is essential for ensuring the mechanical integrity of coaxial cable conductors in various telecommunications and broadcasting environments. The standard’s test methods allow manufacturers to:
- Verify the tensile properties of copper-clad conductors before cable assembly.
- Distinguish between annealed and hard-drawn copper-clad metals to optimize conductor performance based on application needs.
- Guarantee mechanical reliability under operational stresses, preventing cable failures due to conductor fracture or excessive elongation.
- Support quality control processes for production and procurement, aligning with international industry benchmarks.
This standard benefits sectors including cable manufacturing, telecom infrastructure development, satellite communication, and RF systems where coaxial cables are critical.

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 publicati
