Overview
EN 60811-412:2012 is a European standard developed by CLC that defines the test method for thermal ageing of non-metallic materials used in electric and optical fibre cables. Specifically, this standard details the procedure for ageing in an air bomb to evaluate the durability and performance of crosslinked and thermoplastic compounds used as insulating and sheathing materials in cables. It replaces part 8.2 of IEC 60811-1-2:1985 and is to be used alongside EN 60811-100:2012 for best results.
The ageing test simulates thermal stress in a controlled air environment under pressure to assess changes in mechanical properties such as tensile strength and elongation at break. This helps ensure that cable materials maintain integrity and reliability over their expected lifespan.
Key Topics
Scope and Applicability
The test applies primarily to non-metallic cable components including insulation and sheath materials based on crosslinked or thermoplastic compounds. It is relevant for a wide range of electric and optical fibre cables used in energy, communication, and specialized applications.Test Method and Apparatus
The ageing test is conducted in an air bomb-a sealed pressure vessel filled with oil- and moisture-free air at approximately 0.55 MPa. Test specimens prepared as dumb-bell or tubular shapes from cable materials are subjected to elevated temperatures for specified durations.Sample Preparation
Samples are taken from cable or sheath material according to IEC 60811-501 guidelines to ensure consistency. Preparation is crucial for reliable tensile testing post-ageing.Ageing Procedure
Test pieces are placed separated in the chamber to avoid contact, then exposed to the specified ageing temperature and time. Following the thermal exposure, pressure is gradually released to avoid porosity formation, and samples are conditioned at room temperature for at least 16 hours before testing.Measurement and Results Expression
Post-ageing mechanical characteristics, such as tensile strength and elongation at break, are measured according to IEC 60811-501. Results include calculations of percentage variation from untreated samples to quantify degradation. These values help determine material fitness for use.Standards Integration
EN 60811-412 complements other parts of IEC 60811, especially EN 60811-100 (general methods) and EN 60811-501 (mechanical tests), creating a comprehensive framework for cable material testing.
Applications
Quality Assurance for Cable Manufacturers
The ageing in an air bomb test enables manufacturers to verify and certify that cable insulation and sheathing materials meet durability requirements under thermal stress.Material Research and Development
R&D teams use the procedure to develop new polymer compounds with improved thermal ageing resistance for enhanced cable lifetime and safety.Compliance Testing for Safety Regulations
The test ensures materials comply with safety objectives under the Low Voltage Directive (LVD) 2006/95/EC by demonstrating reliable performance in thermal ageing conditions.Maintenance and Lifecycle Assessment
Utilities and industries relying on electric and optical fibre cables apply this ageing test data to predict maintenance schedules and assess cable lifespan in operational environments.
