Overview

SIST EN 60811-509:2012/A1:2018 is a European standard developed by CLC that specifies mechanical test methods for evaluating the resistance of insulation and sheath materials in electric and optical fibre cables to cracking under heat shock conditions. This standard focuses on non-metallic cable materials and provides standardized procedures to assess their durability against thermal stresses that can induce cracking.

This amendment (A1:2017) updates the original EN 60811-509:2012, refining test methodologies and specimen preparation to ensure reliable, reproducible results. The heat shock test outlined is primarily designed for polyvinyl chloride (PVC) compounds but may be applicable to other materials with caution.

Key Topics

• Scope of the Standard:
  Covers mechanical tests for non-metallic insulating and sheath materials in electrical and optical fibre cables, specifically targeting resistance to cracking from heat shock.

• Test Methodology:
  The heat shock test involves winding cable specimens tightly around a mandrel and exposing them to abrupt temperature changes to simulate thermal stress conditions.

• Specimen Preparation:
  Test pieces vary depending on cable diameter, sheath thickness, and cable geometry (round or flat). The standard describes detailed cutting, shaping, and handling methods for consistent testing.

• Mandrel Parameters:
  The diameter of the mandrel and the number of turns for winding test samples are defined based on the sample dimensions to standardize the mechanical strain imposed during testing.

• Result Interpretation:
  Cracking is identified as sharp fissures propagating completely through the insulation or sheath thickness. Rounded deformations caused by polymer melting should not be mistaken for cracks.

• Material Applicability:
  While developed for PVC compounds, application to other non-metallic cable materials requires careful consideration to ensure valid results.

Applications

• Cable Manufacturing Quality Control:
  Ensures insulations and sheaths possess sufficient thermal mechanical durability to withstand installation and service conditions without cracking.

• Material Selection and Development:
  Assists engineers and material scientists in evaluating new or alternative polymer compounds for cable insulation and sheathing.

• Compliance Testing:
  Supports conformance with European electrotechnical regulations by providing consistent testing protocols for cable materials.

• Failure Analysis:
  Helps identify weaknesses in existing cable materials by simulating thermal stress-induced cracking for maintenance and improvement purposes.

Related Standards

• IEC 60811 Series:
  EN 60811-509 is part of the broader IEC 60811 suite that details test methods for various electrical cable non-metallic materials.

• EN 60811-1 Series:
  Provides foundational test methods for general physical and mechanical properties of cable insulating materials.

• Directive 2014/35/EU (Low Voltage Directive):
  EN 60811-509 serves as a supporting standard for electrical safety compliance although the direct link was removed by BT D162/C049; it remains critical for standardized testing.

By following SIST EN 60811-509:2012/A1:2018, manufacturers and testing laboratories can reliably assess the resistance of cable insulations and sheaths to cracking caused by heat shocks, ensuring enhanced longevity and safety in electrical and optical fibre cable applications.
