Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheet 247: Heat-shrinkable, polyolefin sleeving, dual wall, not flame retarded, thick and medium wall
IEC 60684-3-247:2019 is available as IEC 60684-3-247:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 60684-3-247:2019 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, dual wall, not flame retarded with a nominal shrink ratio of 3:1. This sleeving has been found suitable for use at temperatures of up to 100 °C. - Type A: Medium wall, internal diameter up to 200,0 mm typically. - Type B: Thick wall, internal diameter up to 200,0 mm typically. These sleevings are normally supplied in colour black. Since these types of sleving cover a significantly large range of sizes and wall thicknesses, Annex A (Tables A.1 and A.2) provides a guide to the range of sizes available. The actual size will be agreed between the user and supplier. Materials which conform to this specification 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 not based on this specification alone. This second edition cancels and replaces the first edition published in 2011 and Amendment 1:2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions: - removal of the colour fastness to light test, as this is covered by the test for carbon black content; - change of low temperature flexibility test to -20 °C to align with sheet 214; - change of final conditioning temperature of peel strength samples to 200 ºC to align with the temperature in Clause 5; - removal of the fungus resistance test as there is no evidence that fungus growth is an issue either by testing or in use.

IEC 60684-3-247:2019 est disponible sous forme de IEC 60684-3-247:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 60684-3-247:2019 donne les exigences relatives à deux types de gaines thermorétractables en polyoléfine, à double paroi, non ignifugées, dont le rapport de rétreint nominal est 3:1. Ces gaines se sont avérées appropriées pour une utilisation à des températures allant jusqu’à 100 °C. - Type A: Paroi moyenne, diamètre intérieur généralement jusqu’à 200 mm - Type B: Paroi épaisse, diamètre intérieur généralement jusqu’à 200 mm La couleur de ces gaines est normalement le noir. Comme ces types de gaines couvrent une plage très étendue de tailles et d’épaisseurs de paroi, l'Annexe A (Tableaux A.1 et A.2) fournit un guide des tailles disponibles dans cette plage. La taille réelle fait l’objet d’un accord entre l’utilisateur et le fournisseur.Anchor Les matériaux conformes à la présente spécification satisfont à des niveaux de performances établis. Cependant, le choix d’un matériau par un utilisateur, pour une application spécifique, est fondé sur les exigences réelles nécessaires pour obtenir des performances adéquates pour l'application concernée, et n'est pas fondé sur cette seule spécification. Cette deuxième édition annule et remplace la première édition parue en 2011 et l'Amendement 1:2016. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - suppression de l'essai de solidité de la couleur à la lumière, cet essai étant couvert par l'essai de détermination de la teneur en noir de carbone; - modification de la température de l'essai de flexion à basse température qui devient -20 °C pour aligner la valeur avec celle donnée dans la feuille 214; - modification de la température de conditionnement finale des échantillons pour la résistance à l'arrachement qui devient 200 ºC pour aligner la valeur avec celle donnée à l'Article 5; - suppression de l'essai de résistance aux moisissures étant donné qu'il n'a pas été démontré, ni par des essais, ni en fonctionnement, que le développement de moisissures constituait un problème.

Overview
EN IEC 60684-3-247:2019 (Sheet 247) specifies requirements for heat-shrinkable, polyolefin sleeving, dual wall, not flame retarded, in medium and thick wall constructions. The sheet covers two product types (Type A - medium wall; Type B - thick wall) with a nominal shrink ratio of 3:1 and typical internal diameters up to 200.0 mm. This edition is a technical revision of the 2011 standard (with Amendment 2016) and is published as an RLV (Redline Version) showing technical changes versus the previous edition.
Key topics and technical requirements
- Product scope and designation: Identification format (IEC 60684‑3‑247‑[Type]‑[expanded/recovered ID]‑colour) and package labelling requirements.
- Material and construction: Dual‑wall polyolefin sleeving with an inner adhesive layer (dual wall) and outer insulating wall; normally supplied in black.
- Thermal performance: Rated suitable for use up to 100 °C; pre-test conditioning typically involves shrinking in a forced‑air oven at ~200 °C. Final conditioning temperature for peel strength is aligned to 200 °C.
- Mechanical and electrical tests: Property requirements include shrink performance, peel strength, hardness, dimensional tolerances, and breakdown voltage (see tables in the standard).
- Environmental and durability tests: Low‑temperature flexibility test set to −20 °C (aligned with related sheets); removal of fungus resistance test and colour‑fastness to light (carbon black content test covers light stability).
- Size guidance: Annex A (Tables A.1, A.2) provides a guide to available sizes and wall thicknesses; actual sizes are to be agreed between user and supplier.
- Test methods and references: Conformance relies on Part 1 (definitions) and Part 2 (methods of test) of IEC 60684 and referenced standards for materials and test procedures.
Applications and users
- Typical applications: cable and wire insulation, environmental sealing, mechanical protection, electrical insulation for connectors, joints and terminations where heat‑shrinkable polyolefin sleeving is required but flame retardancy is not.
- Who uses it: product designers, material engineers, OEMs, electrical installers, specification writers, procurement teams and test laboratories who need to select, manufacture, test or specify dual‑wall heat‑shrink sleeving for industrial, automotive, telecommunications and general electrical applications.

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 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.

IEC 60684-3-247:2019은 열수축성 폴리올레핀 슬리빙의 요구 사항을 규정하는 표준이다. 이 슬리빙은 듀얼 월이며 방화성이 아니며 3:1의 명목 수축 비율을 가진다. 이 슬리빙은 최대 100°C의 온도에서 사용하기에 적합하다. A형은 일반적으로 내경이 최대 200.0mm인 중간 월 슬리빙이다. B형은 일반적으로 내경이 최대 200.0mm인 두꺼운 월 슬리빙이다. 두 형태 모두 일반적으로 검은색으로 제공된다. 첨부 A에는 이러한 슬리빙 유형에 사용 가능한 크기 범위에 대한 안내가 제공되지만, 실제 크기는 사용자와 공급 업체 간에 합의된다. 이 표준의 이 둘째 판은 2011년에 발표된 첫 번째 판을 대체하며, 일부 기술적인 변경 사항이 포함되어 있다. 이 변경 사항에는 탄색 테스트를 위한 광속 안정성 테스트의 제거, 시트 214와 일치하기 위해 낮은 온도의 유연성 테스트를 -20°C로 변경하고, 껍질 강도 샘플의 최종 조건 온도를 200°C로 변경하는 등이 있다. 곰팡이 저항 테스트는 공란으로 처리되었는데, 테스트나 사용에서 곰팡이 성장이 문제가 되지 않는 것으로 판단되기 때문이다. 전반적으로, 이 표준은 성능 수준을 충족하는 열수축성 폴리올레핀 슬리빙의 사양을 제공하지만, 특정 응용 프로그램에 대한 재료 선택은 해당 응용 프로그램에서 충분한 성능을 위해 실제 요구 사항에 기반해야 한다.
IEC 60684-3-247:2019 is a standard that specifies the requirements for two types of heat-shrinkable, polyolefin sleeving. These sleeving types are dual wall and not flame retarded, with a nominal shrink ratio of 3:1. They are suitable for use at temperatures up to 100°C. Type A is a medium wall sleeving with an internal diameter typically up to 200.0mm. Type B is a thick wall sleeving with an internal diameter typically up to 200.0mm. Both types are usually supplied in black color. Annex A provides a guide to the range of sizes available for these sleeving types, but the actual size will be determined by agreement between the user and supplier. This second edition of the standard replaces the first edition published in 2011 and includes some technical changes. These changes include the removal of the color fastness to light test, as it is covered by the test for carbon black content. The low temperature flexibility test has been changed to -20°C to align with sheet 214, and the final conditioning temperature of peel strength samples has been changed to 200°C to align with Clause 5. The fungus resistance test has been removed as there is no evidence that fungus growth is an issue in testing or use. Overall, this standard provides specifications for heat-shrinkable, polyolefin sleeving that meet established levels of performance, but the selection of a specific material for a particular application should be based on the actual requirements for adequate performance in that application.

IEC 60684-3-247:2019는 불연화처리되지 않은 폴리올레핀 소매지의 두 가지 유형인 이중벽 열축소용시침에 대한 요구사항을 제시합니다. 이 소매지는 3:1의 명목 축소 비율을 가지며 최대 100°C의 온도에서 사용하기에 적합하다고 입증되었습니다. - 유형 A: 중간 벽 두께, 내부 지름은 일반적으로 200 mm까지입니다. - 유형 B: 두꺼운 벽 두께, 내부 지름은 일반적으로 200 mm까지입니다. 이러한 소매지들은 일반적으로 검은 색으로 공급됩니다. 이러한 유형의 소매지는 큰 범위의 크기와 벽 두께를 커버하기 때문에 부록 A (표 A.1 및 A.2)에서 사용 가능한 크기 범위를 안내합니다. 실제 크기는 사용자와 공급자 간에 합의됩니다. 이 사양을 준수하는 재료는 성능 수준을 충족합니다. 그러나 특정 응용에 적합한 성능을 위해 사용자가 재료를 선택할 때는 이 사양만을 기준으로 하지 않고 그 응용에 필요한 실제 요구 사항을 기반으로 할 것입니다. 이 두 번째 판은 2011년에 출판된 첫 번째 판 및 2016년 개정 1판을 취소하고 대체합니다. 이 번째 판은 기술적 개정을 구성합니다. 이번 판에는 이전 판에 비해 다음과 같은 중요한 기술적 변경 사항이 포함되어 있습니다. - 탄소 블랙 함량 측정을 위한 검색재내성 시험의 제거, - 저온 유연성 시험을 -20℃로 변경하여 시트 214와 일치시킵니다. - 접착력 샘플의 최종 조건부 온도를 200°C로 변경하여 조항 5의 온도와 일치시킵니다. - 곰팡이 저항성 시험의 제거, 시험 또는 사용 중에 곰팡이 발생이 문제가 되지 않음을 입증한 증거가 없기 때문입니다. 이 기사의 키워드는 열축소용시침, 폴리올레핀 소매지, 이중벽, 불연화처리되지 않은, 두꺼운 및 중간 벽입니다.
IEC 60684-3-247:2019は、2種類の熱収縮性ポリオレフィンスリーブの要件を規定する国際規格です。これらのスリーブはデュアルウォールであり、防炎処理はされておらず、名目収縮比が3：1です。これらのスリーブは最大100°Cの温度で使用することが適しています。 A型は一般的に内径が最大200.0 mmのミディアムウォールスリーブです。B型は一般的に内径が最大200.0 mmの厚いウォールスリーブです。両タイプは通常黒色で供給されます。 付録Aには、これらのスリーブタイプの利用可能なサイズ範囲のガイドが提供されていますが、実際のサイズはユーザーとサプライヤーの間で合意されます。 この規格の第2版は、2011年に発行された第1版と置き換えられ、一部の技術的変更が含まれています。変更内容には、炭素黒含有量のテストにより色の褪色耐性テストを削除すること、シート214との整合性を図るために低温柔軟性テストを-20°Cに変更すること、クローズ5の温度と一致するように剥離強度サンプルの最終調整温度を200°Cに変更すること、使用やテストにおいてはカビの発生が問題になっていないためカビ耐性テストを削除することなどがあります。 全体として、この規格は、確立された性能水準を満たす熱収縮性ポリオレフィンスリーブの仕様を提供しますが、特定の用途に適した材料の選択は、その用途で適切な性能を達成するために実際の要件に基づいて行う必要があります。
IEC 60684-3-247:2019は、以前の版との技術的内容の変更点をすべて示す国際規格およびレッドライン版であるIEC 60684-3-247:2019 RLVが利用可能です。IEC 60684-3-247:2019は、燃焼防止処理されていないポリオレフィンスリーブの中で、2種類のヒートシュリンク可能な二重壁スリーブの要件を示しています。このスリーブは、3：1の名目収縮比を持ち、最大100℃の温度で使用することが適しているとされています。 - Aタイプ：中厚壁、内径は通常200.0mmまで - Bタイプ：厚壁、内径は通常200.0mmまで これらのスリーブは通常、黒色で供給されます。この種のスリーブは、非常に広範なサイズと壁厚をカバーしているため、付録A（A.1およびA.2表）では、利用可能なサイズの範囲をガイドとして提供しています。実際のサイズは、ユーザーとサプライヤーの間で合意されます。この仕様に準拠する材料は、確立された性能レベルを満たします。ただし、特定のアプリケーションに適した材料を選択する際には、この仕様のみを基にせず、そのアプリケーションでの適切な性能に必要な実際の要件に基づく必要があります。この第2版は、2011年に発行された第1版および改訂版1:2016を取り消し、置き換えるものです。この版は技術的な改訂を構成しており、以下の重要な技術的変更が前版と比較して含まれています： - 光安定性試験の削除（カーボンブラック含有試験でカバーされるため）。 - 低温柔軟性試験を-20℃に変更して、シート214と一致させる。 - 剥離強度サンプルの最終調整温度を200℃に変更して、条項5の温度に一致させる。 - 真菌耐性試験を削除し、テストまたは使用中に真菌の成長が問題とならない証拠がないため。 この記事のキーワードは、ヒートシュリンク可能な、ポリオレフィンスリーブ、二重壁、燃焼防止処理されていない、厚壁および中厚壁です。
The article discusses the specifications for heat-shrinkable, polyolefin sleeving, specifically focusing on a dual wall type that is not flame retarded. The sleeving has a nominal shrink ratio of 3:1 and is suitable for use at temperatures up to 100°C. There are two types available: Type A, which has a medium wall and an internal diameter up to 200.0mm, and Type B, which has a thick wall and an internal diameter up to 200.0mm. These sleeving types are typically supplied in black color. Annex A provides a guide to the range of sizes available, but the actual size will be agreed upon between the user and supplier. This second edition of the specification replaces the first edition published in 2011 and includes changes such as the removal of certain tests that were deemed unnecessary and alignment with other standards. Users will need to consider their specific application requirements when selecting a material based on this specification. The keywords for this article are: heat-shrinkable, polyolefin sleeving, dual wall, not flame retarded, and thick and medium wall.
