SIST EN 60811-512:2012

Electric and optical fibre cables - Test methods for non-metallic materials - Part 512: Mechanical tests - Tensile strength and elongation at break after conditioning at elevated temperature - Methods specific to polyethylene and polypropylene compounds

IEC 60811-512:2012 describes the procedure for testing tensile strength and elongation at break after conditioning at elevated temperature. It is specific to polyethylene and polypropylene compounds. This test is intended for samples from filled cables, of polyolefin insulations with a wall thickness of more than 0,8 mm and for polyolefin sheaths in direct contact with filling compound. IEC 60811-512:2012 cancels and replaces Clause 8 of IEC 60811-4-2:2004, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100:2012.[

Overview

SIST EN 60811-512:2012 is a European standard aligned with IEC 60811-512:2012 that specifies test methods for non-metallic materials used in electric and optical fibre cables. Focusing on polyethylene and polypropylene compounds, this standard details mechanical testing procedures for measuring tensile strength and elongation at break after conditioning specimens at elevated temperatures. It replaces Clause 8 of the earlier EN 60811-4-2:2004 standard and is intended for samples taken from filled cables with polyolefin insulation thicker than 0.8 mm or polyolefin sheaths in direct contact with filling compounds. This standard supports ensuring the reliability and performance of cable materials under thermal stress conditions.

Key Points

• Scope: Applies to polyolefin insulating and sheathing compounds, specifically polyethylene and polypropylene, used in electric and optical fibre cables.
• Conditioning Requirements: Samples are conditioned in air at elevated temperatures for 7 consecutive days-either at 60 ± 2 °C or 70 ± 2 °C, depending on the nominal drop point of the filling compound. Following conditioning, samples rest at ambient temperature for at least 16 hours before testing.
• Test Methods: Tensile strength and elongation at break are measured according to IEC 60811-501 protocols, without additional ageing after conditioning.
• Sample Preparation: Testing is conducted on cable samples extruded or cross-linked no less than 16 hours prior to testing. For multicore cables, up to three cores may be tested unless otherwise specified.
• Result Reporting: Median values for tensile strength and elongation at break are reported, following the format established in IEC 60811-100.
• Normative References: This standard is to be used in conjunction with EN 60811-100:2012 (General test methods) and EN 60811-501 (Mechanical tests for insulating and sheathing compounds).

Applications

SIST EN 60811-512:2012 is critical for manufacturers, quality assurance teams, and testing laboratories involved in the production and evaluation of non-metallic materials in power, communication, and fibre optic cables. It helps to:

• Ensure material durability under elevated thermal conditions, simulating real operating environments.
• Verify that polyolefin insulations and sheaths meet specified mechanical performance criteria after exposure to heat.
• Support compliance with international regulations and enhance product reliability in various sectors, including energy distribution, telecommunications, and offshore installations.
• Provide standardized test protocols for evaluating cable insulation and sheath integrity, critical for maintaining electrical safety and performance.

Related Standards

• EN 60811-100:2012 - General test methods for non-metallic materials used in electric and optical fibre cables; provides foundational procedures referenced within EN 60811-512.
• EN 60811-501 - Mechanical tests for determining properties of insulating and sheathing compounds; describes tensile strength and elongation test methodologies.
• EN 60811-4-2:2004 - Previous edition partially superseded by EN 60811-512, originally covering polyethylene and polypropylene materials.
• IEC 60811 series - Comprehensive suite of test methods covering various properties of non-metallic cable materials for global standardization.

By adhering to SIST EN 60811-512:2012, stakeholders ensure rigorous and consistent evaluation of polyolefin cable materials, enhancing the safety and longevity of electrical and optical fibre cable installations globally.
