Heat-shrinkable low and medium voltage moulded shapes - Part 3: Specification for individual materials - Sheet 101: Heat-shrinkable, polyolefin moulded shapes for low voltage applications

IEC 62677-3-101:2018 is applicable to heat shrinkable low voltage moulded shapes in a range of configurations suitable for insulation, environmental sealing, mechanical protection, strain relief for power cable terminations, joints and stop ends. These moulded shapes have been found suitable for use for temperatures between -40 °C and 100 °C. The moulded shapes can be supplied with a pre-coated adhesive. A guide to adhesive compatibility and temperature performance is given in Annex A. The manufacturers/suppliers can be consulted for options. The material is available in two types: - Type A - Flame retardant - Type B - Not flame retardant Materials which conform to this document meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and will not be based on this document alone. The tests specified are designed to control the quality of the moulded shapes but it is recognized that they are designed to be used in low and medium voltage cable accessories and, as such, electrical performance will be proven as part of the assembly. Examples of this are described in EN 50393, HD 629 and IEC 60502-1. Keywords: Heat-shrinkable, polyolefin moulded shapes for low voltage applications

Ces profilés sont jugés adaptés pour des utilisations dans la plage de températures de –40 °C à 100 °C. Les profilés peuvent être fournis avec un adhésif prérevêtu. L'Annexe A fournit un guide sur la compatibilité des adhésifs et la performance en température. Les fabricants/fournisseurs peuvent être consultés pour les options. Deux types de matériaux sont disponibles: - Type A - Retardateur de flamme - Type B - Non retardateur de flamme Les matériaux conformes au présent document satisfont à des niveaux établis de performance. Cependant, le choix d’un matériau par un utilisateur, pour une application spécifique, sera fondé sur les exigences réelles nécessaires pour obtenir une performance adéquate pour l'application concernée, et ne sera pas fondé sur ce seul document. Les essais spécifiés sont conçus pour contrôler la qualité des profilés, mais il est reconnu qu'ils sont conçus pour être utilisés dans des accessoires de câbles basse et moyenne tensions et, à ce titre, la performance électrique sera prouvée dans le cadre de l'assemblage.

Ta del IEC 62677 velja za toplotno skrčljive ulite forme za uporabo pri nizkih napetostih v različnih konfiguracijah, primernih za izolacijo, zaščito pred okoljskimi vplivi, mehansko zaščito za razbremenitev za ozemljitve napajalnih kablov, spojk in slepih končnikov. Te ulite forme so primerne za uporabo pri temperaturah od –40 °C do 100 °C.
Brizgane forme so lahko predhodno premazane z lepilom. Vodnik po združljivosti lepil in temperaturnega delovanja je podan v dodatku A. O možnostih se lahko posvetujete s proizvajalci/dobavitelji.
Na voljo sta dve vrsti tega materiala:
Tip A – negorljiv
Tip B – gorljiv
Materiali, ki so skladni s tem dokumentom, ustrezajo določenim ravnem delovanja. Vendar bo uporabnik material za določeno uporabo izbral glede na dejanske zahteve, ki omogočajo ustrezno delovanje pri tej uporabi, in ne samo na podlagi te specifikacije.
Opisani preskusi so namenjeni nadzoru nad kakovostjo ulitih form, pri čemer se upošteva, da so zasnovane za uporabo z nizko- in srednjenapetostnimi kabli, zato se kot del sestava preverja tudi električna zmogljivost. Primeri tega so opisani v standardih EN 50393, HD 629 in IEC 60502-1.

Overview

EN IEC 62677-3-101:2018 specifies requirements for heat‑shrinkable, polyolefin moulded shapes for low voltage applications. It applies to molded parts used for insulation, environmental sealing, mechanical protection and strain relief in cable terminations, joints and stop‑ends. Materials covered are suitable for service temperatures between –40 °C and 100 °C, and can be supplied with pre‑coated adhesive. Two material types are defined: Type A (flame retardant) and Type B (not flame retardant). The standard is part of the IEC 62677 series and is intended to control material quality for use in low/medium voltage cable accessories.

Key Topics and Requirements

• Material scope: Heat‑shrinkable polyolefin compositions for low voltage moulded shapes (insulation, sealing, mechanical protection).
• Temperature range: Suitable for –40 °C to 100 °C service conditions.
• Types: Type A = flame retardant; Type B = not flame retardant.
• Adhesives: Option for pre‑coated adhesives; Annex A provides an adhesive compatibility and temperature‑performance guide. Suppliers should be consulted for adhesive options.
• Designation and labelling: Defined supplier/product designation format (e.g., IEC 62677‑3‑101‑A‑U‑BK‑X).
• Conformance testing:
  • Conformance based on test sheets prepared from the same cross‑linked material (typically 2 ± 0.15 mm thick).
  • Dimensional shrink test: samples shrunk in a forced‑air oven at 200 °C ± 5 K for (10 ± 1) min.
  • Heat‑shock tests (example condition shown at 175 °C ± 5 K).
  • Mechanical properties: tensile strength (min. 8 MPa) and elongation at break (min. 200%).
  • Low‑temperature bending: no visible cracking at –40 °C (mandrel 20–22 × sample thickness).
• Quality control objective: Tests in this sheet are designed to control material quality; electrical performance is verified at the assembly level (see EN 50393, HD 629, IEC 60502‑1).

Applications

• Insulation and environmental sealing for low‑voltage cable terminations and joints.
• Strain relief and mechanical protection for power cable accessories.
• Stop‑ends and bespoke moulded components used in distribution networks and industrial installations. Practical use involves selecting the correct type (A or B), adhesive system, and verifying that tested mechanical and thermal properties match the application environment.

Who should use this standard

• Cable accessory manufacturers and material suppliers.
• Design engineers specifying heat‑shrink components for low‑voltage systems.
• Test labs and quality assurance teams validating material conformance.
• Procurement specialists assessing supplier data sheets against IEC requirements.

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 conf
