IEC 60811-602:2012 gives the test methods for separation of oil in filling compounds. IEC 60811-602:2012 cancels and replaces Clause 5 of IEC 60811-5-1:1990, which is withdrawn.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. This publication is to be read in conjunction with IEC 60811-100:2012.

Overview

IEC 60811-602:2012 is an international standard published by the International Electrotechnical Commission (IEC) that specifies test methods for assessing the separation of oil in filling compounds used in non-metallic materials of electric and optical fibre cables. It forms part of the wider IEC 60811 series, which encompasses standardized testing procedures for non-metallic cable materials. This part of the standard specifically addresses physical testing to evaluate how oil separates from filling compounds under defined conditions, ensuring material performance and reliability in cable manufacturing and application.

Key Topics

Scope and Purpose IEC 60811-602:2012 defines the test method for measuring the extent of oil separation from filling compounds used inside cables. Maintaining minimal oil separation is critical for cable integrity and operational safety.

Test Methodology The standard outlines a precise procedure to heat the filling compound to its clarity point and then cool it in a specially designed angle box. After cool-down, the box is heated to 50 ± 2 °C to stimulate oil separation. The separated oil’s spread is measured after 24 hours to verify compliance.

Apparatus and Equipment The test involves an angle box with two rectangular cases fitting standardized dimensions. The surface finish of the box supports the unhindered spread of oil for accurate measurement.

Measurement and Results The oil separation distance into the unfilled area must not exceed 5 mm as per the normative Annex A, ensuring the filling compound maintains its required stability.

Normative References This test method is to be read and applied in conjunction with IEC 60811-100:2012, which provides general guidelines for testing non-metallic cable materials.

Applications

IEC 60811-602:2012 is essential for:

Cable Manufacturers Validating the quality and stability of filling compounds used in insulation, bedding, or sheathing within electrical and optical fibre cables.

Quality Assurance Ensuring filling materials comply with international standards to prevent premature cable failure caused by oil migration.

Materials Research Testing and development of new non-metallic cable compounds, particularly for energy cables, communication cables, and cables used in harsh environments like offshore and marine applications.

Regulatory Compliance Assisting manufacturers and testing laboratories in demonstrating adherence to internationally recognized testing protocols, facilitating global market acceptance.

Related Standards

IEC 60811-100:2012 – General test methods for non-metallic materials of electric and optical fibre cables, providing foundational guidance for the test procedures in Part 602.

IEC 60811 Series – Comprehensive suite of standards covering various physical and chemical tests on non-metallic cable components such as insulation, sheathing, filling, and taping materials.

Withdrawn Reference: IEC 60811-5-1:1990 – The earlier clause on oil separation replaced by IEC 60811-602:2012, with no significant technical changes, ensuring continuity and improved standardization.

Summary

IEC 60811-602:2012 is vital for ensuring the physical stability of filling compounds in electrical and optical fibre cables through standardized oil separation testing. It supports manufacturers and testing bodies in maintaining cable quality and performance, thereby enhancing safety and reliability in energy, communication, and industrial cable applications worldwide. Integrating this standard alongside other IEC 60811 series parts offers a robust framework for non-metallic cable material testing aligned with global best practices.
