Overview

EN 60684-3-248:2007 (IEC 60684-3-248) specifies requirements for general purpose, heat‑shrinkable, dual‑wall polyolefin sleeving with a flame‑retarded outer wall and an adhesive inner wall. The sheet covers six product types with nominal shrink ratios 2:1, 3:1 and 4:1, and inner‑wall adhesives rated for low (suitable to 105 °C) or high (suitable to 125 °C) temperature applications. Typical supply colour is black; other colours/sizes can be used if they meet the listed property requirements.

Key topics and technical requirements

• Product types and shrink ratios:
  • Type AL/AH - 2:1 (AL: low‑temp adhesive; AH: high‑temp adhesive)
  • Type BL/BH - 3:1
  • Type CL/CH - 4:1
  • Maximum nominal internal diameters are specified (e.g., up to 51 mm for 2:1, 40 mm for 3:1, 52 mm for 4:1).
• Construction: outer flexible cross‑linked polyolefin; inner hot‑melt adhesive that flows during shrinking to form a bond.
• Temperature ratings: inner adhesive choices rated for service up to 105 °C (low) and 125 °C (high).
• Testing and conformity:
  • Uses test methods referenced in IEC 60684‑2 and general requirements in IEC 60684‑1.
  • Includes dimensional tolerances, electrical breakdown voltage, elevated temperature performance, resistance to selected fluids and other property tables (see Tables 5–8 in the standard).
  • Preparatory shrink step: specimens are normally shrunk in a forced‑air oven (200 °C ±5 K for ~5 min) prior to testing.
  • Conformance is typically assessed on specific black sample sizes listed in the standard.
• Designation and colour coding: follows IEC 60757 colour codes and a standard designation format (e.g., Sleeving IEC 60684‑3‑248‑AL‑12.7/6.4‑BK).

Applications and who uses this standard

• Applications: electrical insulation, mechanical protection, environmental sealing and strain relief for wiring and cable harnesses where flame retardancy and a moisture‑resistant bonded seal are required.
• Users:
  • Manufacturers of heat‑shrinkable polyolefin sleeving and cable accessories
  • Component specifiers and product engineers in electronics, automotive, aerospace, marine and electrical installation sectors
  • Test laboratories and quality managers who perform conformity and type‑approval testing
  • Procurement and compliance teams ensuring CENELEC/IEC referenced products meet European normative requirements

Related standards

• IEC 60684‑1: Definitions and general requirements
• IEC 60684‑2: Methods of test (with Amendments)
• IEC 60757: Codes for designation of colours
• ISO 1817: Determination of the effect of liquids (referenced for fluid resistance testing)

This standard is essential when specifying or testing heat‑shrinkable polyolefin sleeving to ensure consistent mechanical, thermal and electrical performance and to meet flame‑retardant and adhesive bonding expectations.

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 correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60684-3-248 has been prepared by IEC technical committee 15:
