Overview
IEC 61196-1-305:2026, titled "Coaxial communication cables - Part 1-305: Mechanical test methods - Solderability and resistance to soldering," is an international standard developed by the International Electrotechnical Commission (IEC). This standard outlines precise mechanical test methods for determining both the solderability and the resistance to soldering of inner and outer conductors in coaxial communication cables. The standard is relevant to cables applied in a wide range of analogue and digital communication systems, ensuring the reliability and performance of cable joints and terminations in electronic networking, broadcasting, telecommunications, and data transfer applications.
This second edition reflects significant technical revisions and enhancements to support evolving communication technologies, including updates in specimen preparation, testing procedures, requirements, and reporting.
Key Topics
IEC 61196-1-305:2026 addresses several fundamental topics essential for manufacturers, quality assurance personnel, and technical engineers in the communication cable sector:
- Solderability Testing: Specifies methods to assess the ability of cable conductors to be properly tinned for soldering, ensuring strong electrical and mechanical connections.
- Resistance to Soldering: Defines procedures to evaluate how cable conductors withstand the heat and process conditions of soldering without suffering detrimental effects, such as insulation displacement or conductor deformation.
- Specimen Preparation: Details steps for preparing cable specimens for both solderability and resistance tests, tailored to specific cable types (including semi-flexible and semi-rigid cables).
- Test Requirements and Procedures: Incorporates updated protocols after referencing IEC 60068-2-20, covering test temperatures, immersion depths and durations, and acceptance criteria for both soldering process outcomes and physical measurement tolerances.
- Test Reporting: Introduces structured reporting guidelines to ensure all critical test parameters and results are documented, aiding traceability and compliance auditing.
- Specifications for Relevant Cables: Outlines information that must be detailed in cable specifications, such as test objects, conditions, and any deviations from standard procedures.
