IEC 60684-3-247:2019

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.

Gaines isolantes souples - Partie 3: Spécifications pour types particuliers de gaines - Feuille 247: Gaines thermorétractables en polyoléfine, à double paroi, non ignifugées à paroi épaisse et moyenne

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.

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

1 Scope
This part of IEC 60684 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 sleevings 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 shall 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 should will be based on the actual
requirements necessary for adequate performance in that application and not based on this
specification alone.
