Flexible insulating sleeving -- Part 3: Specifications for individual types of sleeving -- Sheet 246: Heat-shrinkable polyolefin sleeving, dual wall, not flame retarded

Defines requirements for dual wall, not flame retarded, heat shrinkable, polyolefin sleeving. This sleeving has been found suitable for use up to 80 °C. The sleeving consists of an outer layer made of a semi-rigid cross-linked material. The inner layer is a substantially non-cross-linked polyolefin that flows and fuses during the shrinkage process to provide a seal. It is normally offered for sale with an internal diameter up to 25 mm in the following colours: black, white, red, yellow, blue and translucent. Sizes or colours other than those listed in this standard may be available as custom items. These items shall be considered to comply with this standard if they comply with the property requirements listed in tables 2, 3, 4 and 5, excluding dimensions. Materials which conform to this specification 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 specification alone.

Donne les prescriptions relatives aux gaines thermorétractables en polyoléfine, double paroi, non retardées à la flamme. Il a été constaté que ces gaines étaient adaptées à une utilisation allant jusqu'à 80 °C. Ces gaines sont composées d'une couche externe faite d'un matériau semi-rigide réticulé. La couche interne est principalement en polyoléfine non réticulée qui coule et fond au cours du processus de rétreint pour réaliser une étanchéité. Ces gaines sont normalement fournies avec des diamètres intérieurs allant jusqu'à 25 mm et avec les couleurs suivantes: noir, blanc, rouge, jaune, bleu et translucide. D'autres dimensions et d'autres couleurs que celles indiquées dans cette norme peuvent être disponibles comme articles spéciaux. Ces articles doivent être considérés comme satisfaisant à cette norme s'ils satisfont aux exigences indiquées dans les tableaux 2, 3, 4 et 5, dimensions excluses. Les matériaux conformes à cette spécification satisfont à des niveaux établis de performance. Cependant, il convient que le choix d'un matériau par un utilisateur, pour une application spécifique, soit fondé sur les exigences réelles nécessaires pour une performance adéquate de cette application, et non fondé sur cette seule spécification.

Overview

EN 60684-3-246:2007 (Sheet 246 of IEC 60684 Part 3) specifies requirements for heat-shrinkable polyolefin sleeving, dual wall, non‑flame retarded. The standard covers construction, dimensions, property requirements and test methods for dual‑wall sleeving consisting of a semi‑rigid, cross‑linked outer layer and a substantially non‑cross‑linked inner layer that flows during shrinkage to form a seal. It is normally offered up to 25 mm internal diameter in black, white, red, yellow, blue and translucent. (The IEC text cites suitability up to 110 °C; some summaries may reference other service temperatures.)

Key topics and technical requirements

• Construction: Outer semi‑rigid cross‑linked polyolefin; inner heat‑flowing polyolefin to provide sealing.
• Sizes & colours: Typical offered internal diameters up to 25 mm and six standard colours; custom sizes/colours may comply if they meet the property tables.
• Performance tables: Conformance is assessed against the property requirements in Tables 1–5 (dimensions, mechanical/electrical properties, breakdown voltage, resistance to fluids).
• Test methods & conditioning: Tests reference IEC 60684‑1 and IEC 60684‑2 methods. Typical conditioning includes oven recovery at 200 °C and sealing performance tests using a heated clamping tool and water/air leak checks.
• Sealing performance: Defined procedure for heat, clamp and pressure/leak testing to verify the inner layer fuses to form a watertight seal.
• Designation & marking: Standard provides the designation format (IEC 60684‑3‑246 plus size and colour codes) for product identification.

Applications and who uses it

• Electrical insulation and protection for splices, terminals and terminations where a non‑flame‑retarded, sealed sleeve is acceptable.
• Moisture and environmental sealing for cables and wiring harnesses in consumer electronics, industrial equipment and certain automotive or appliance assemblies (selection should match actual service requirements).
• Manufacturers, OEMs, procurement and QA teams use this standard to specify material performance, validate test methods and assess supplier conformance.
• R&D and test labs apply the normative tests (IEC 60684‑2) and sealing procedures described to verify product performance.

Related standards

• IEC/EN 60684‑1: Definitions and general requirements
• IEC/EN 60684‑2: Methods of test
• IEC 60757: Colour designation
• ISO 1817: Effect of liquids on rubber (referenced for fluid resistance)

This standard helps ensure consistent performance and testability of dual‑wall heat‑shrink polyolefin sleeving used for electrical insulation and environmental sealing. When selecting material, users should match the sleeving’s tested properties to the actual application requirements rather than relying on the specification alone.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the c
