Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheet 284: Heat-shrinkable sleevings, for oil barrier applications

IEC 60684-3-284:2014 gives the requirements for heat-shrinkable sleevings for oil barrier, medium voltage cable jointing and termination applications, with nominal shrink ratios of up to 3:1. These sleevings have been found suitable for use up to temperatures of 80 °C. Included are Type A: polyolefin based and Type B: fluoropolymer based, enhanced oil resistance. These sleevings are normally supplied as translucent. Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Annex A, Tables A.1 and A.2, in this document, provide a guide to the range of sizes available. The actual size will be agreed between the purchaser and supplier. Materials which conform to this standard meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this standard alone. This sleeving is designed to be used in MV cable accessories and as such, electrical performance as defined as part of the assembly. Examples of this are described in HD 629 and IEC 60502 series.

Overview

EN 60684-3-284:2014 (IEC 60684-3-284:2014) specifies requirements for heat-shrinkable sleevings for oil barrier use in medium voltage (MV) cable jointing and termination applications. The sheet covers heat‑shrinkable sleeving with nominal shrink ratios up to 3:1, suitable for service temperatures up to 80 °C, and normally supplied translucent. Two material types are defined:

• Type A - polyolefin-based
• Type B - fluoropolymer-based (enhanced oil resistance)

The standard is part of the IEC 60684 series and should be applied together with the general definitions and test methods given in IEC 60684‑1 and IEC 60684‑2.

Key topics and requirements

The document sets out technical requirements and test conditions that ensure predictable performance of oil‑barrier heat‑shrinkable sleeving. Key topics include:

• Material types and intended use: differentiation of Type A and Type B based on polymer chemistry and oil resistance.
• Shrink ratio and sizing: nominal shrink ratios up to 3:1; Annex A (Tables A.1, A.2) provides a guide to typical expanded/recovered sizes and wall thicknesses; exact sizes agreed between purchaser and supplier.
• Pre-test shrink conditions: forced‑air oven shrink prior to testing - 175 °C ±3 K for Type A and 200 °C ±3 K for Type B for 10 ±1 minutes.
• Mechanical and thermal tests: longitudinal change, heat shock, tensile strength, elongation at break, secant modulus, dimensional stability, and bending at low temperature.
• Electrical and ageing tests: breakdown voltage, volume resistivity, heat ageing and long‑term heat ageing (conditions described in the standard), and resistance to selected fluids (oil compatibility).
• Conformance and labelling: designation format for packaging and guidance on testing a typical size to represent a batch.

Applications and users

This standard is intended for:

• Manufacturers of heat‑shrinkable sleevings and MV cable accessory components.
• Cable accessory designers and specifiers working on medium voltage cable jointing and termination where an oil‑barrier sleeve is required.
• Procurement and quality teams needing material and test acceptance criteria.
• Test laboratories performing conformance testing per IEC 60684‑2 methods.

Practical applications include oil‑barrier layers in MV cable terminations and joints where enhanced oil resistance and reliable shrink performance are required. Note: electrical performance of the complete MV accessory is determined at the assembly level (see HD 629, IEC 60502 series).

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses ari
