Overview

EN 60811-502:2012 is a European standard developed by CLC based on IEC 60811-502:2012. It specifies the test method for determining the shrinkage behavior of insulation materials used in electric and optical fibre cables. This standard replaces Clause 10 of the withdrawn EN 60811-1-3:1995 + A1:2001 and should be read in conjunction with EN 60811-100:2012, which provides general test methods for non-metallic cable materials. The shrinkage test method is essential for evaluating the mechanical performance and reliability of insulation materials under thermal stress, ensuring cable longevity and safety.

Key Topics

• Scope and Purpose: Defines the procedure for the shrinkage test applied to cable insulations, focusing on non-metallic materials used in electric and optical fibre cables.
• Test Methodology:
  • Sampling involves cutting a test piece of specified length from cable cores, ensuring minimal alteration to insulation.
  • Preparation includes removing extraneous coverings and marking the test length accurately before testing.
  • The test piece is exposed to a specified temperature in an air oven or on a preheated talc bath for a designated duration.
  • Post-treatment, the shrinkage is measured by comparing the distance between pre-marked points before and after heating.
• Equipment Requirements: Requires an electrically heated air oven capable of maintaining test temperature and precise measuring devices with a scale division of 0.5 mm.
• Shrinkage Calculation: Expressed as a percentage difference in length before and after the heat treatment, calculated with precision for repeatability.
• Reporting: Test results are compiled according to the guidelines in EN 60811-100:2012 for consistency and traceability.

Applications

• Cable Manufacturing: Ensures that the insulating materials used in manufacturing conform to shrinkage standards to prevent defects during thermal cycling.
• Quality Control: Provides a robust method for testing materials for insulation shrinkage, enabling manufacturers to monitor product consistency and performance.
• Product Certification: Supports compliance with safety regulations and standards, particularly within the Low Voltage Directive (LVD - 2006/95/EC).
• Research and Development: Assists in material selection and development for high-performance insulating compounds with minimal shrinkage.
• Maintenance and Reliability: Shrinkage testing informs longevity assessments of cables used in energy distribution, telecommunications, and industrial automation.

• EN 60811-1-3:1995 (withdrawn): Former standard partially replaced by EN 60811-502:2012.
• IEC 60811 Series: Covers comprehensive test methods for non-metallic materials used in a wide variety of cable types.
• LVD 2006/95/EC: European directive ensuring electrical equipment safety, which products tested under this standard contribute to compliance with.
• Additional normative references cited within EN 60811-502:2012 ensure the standard's applicability and integration with other testing protocols.
