General Information
Overview
EN IEC 60794-1-220:2022 is a European Standard developed by the CLC under the International Electrotechnical Commission (IEC). This standard specifies generic requirements and test procedures for optical fibre cables, focusing specifically on environmental test methods related to salt spray corrosion. It outlines a controlled test method-Method F20-to assess the resistance of optical ground wire (OPGW) and optical phase conductor (OPPC) cables against corrosive salt atmospheres, simulating conditions found in marine or coastal environments. These cables incorporate metallic wires exposed directly to the environment and contain embedded optical fibres without protective insulation, making corrosion resistance crucial for durability and performance.
Key Topics
Scope and Application
The standard applies to optical fibre cables, specifically OPGW and OPPC types, used in aerial installations where metallic cable components are exposed. It addresses their ability to withstand long-term exposure to salt spray conditions.Test Samples and Apparatus
Three cable samples approximately 75 cm in length are prepared with heat shrink tubing or silicone seals on both ends. The test apparatus aligns with IEC 60068-2-11, which details environmental salt mist testing methods.Salt Spray Corrosion Test Procedure
- Pre-Test Cleaning: Samples must be free from contamination or debris and fully dried prior to exposure.
- Test Conditioning: Samples are mounted at a 15°-30° angle in a salt spray chamber for 1000 continuous hours.
- Post-Test Handling: After exposure, samples are cleaned to remove salt deposits without damaging the cable surface.
- Visual Inspection: Includes unaided eye and low magnification inspection of corrosion signs. Light brushing to remove deposits is permissible without disturbing underlying surfaces.
Pass/Fail Criteria
The cables pass if:- No pitting exposes steel strength members.
- Aluminium wires have minimal pitting (max 10% wire diameter depth).
- Optical fibre units show no material loss, deformation, or damage impairing performance.
- Aluminium or other coatings on tubing remain intact without exposure of underlying metal.
Applications
This standard is essential for manufacturers, testing laboratories, and utilities involved in the deployment of optical fibre cables in challenging environmental conditions such as coastal or offshore installations. It ensures:
- Product Reliability: Verification of the cable’s capacity to resist salt corrosion prevents premature failures.
- Safety and Network Integrity: Maintaining cable structural and optical performance enhances safety and network uptime.
- Quality Assurance: Provides a standardized test recognized internationally for certifying cable durability under salt exposure.
- Environmental Suitability: Assists in specifying cables fit for use in corrosive atmospheres, extending lifecycle and reducing maintenance costs.
Related Standards
EN IEC 60794-1-220:2022 references and is aligned with the following key standards:
- IEC 60068-2-11: Environmental testing – Part 2-11: Tests – Test Ka: Salt mist, which defines the salt spray test apparatus and operational conditions used in this testing method.
- IEC 60794-Series: A collection of standards for optical fibre cables covering generic specifications, construction, testing, and environmental procedures.
For professionals working with optical fibre cables, EN IEC 60794-1-220 serves as a fundamental reference to ensure cable resilience in corrosive environments, safeguarding both the mechanical and optical properties of OPGW and OPPC cables against salt spray corrosion. Implementing this standard supports industry best practices, enhances product longevity, and aligns with international testing protocols.
