Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheets 343 to 345: Expandable braided ethylene chlorotrifluoroethylene (E-CTFE) textile sleeving, uncoated

Gives the requirements for sleeving having the property of expanding its internal diameter when compressed longitudinally and thereafter returning to its initial diameter after release of the compressing force. This expandable braided textile sleeving, uncoated, is constructed of ethylene chlorotrifluoroethylene (E-CTFE) monofilament yarns suitably processed to provide the mechanical ability to conform in the manner described above. These sleevings have been found suitable for use at temperatures up to 155 °C. This sleeving is normally supplied in internal diameters between 6 mm and 63 mm and in three levels of wall thickness (thin (sheet 343), medium (sheet 344), and thick (sheet 345)). Because of its open construction, this sleeving is normally used to provide air-space insulation. Therefore, no requirement for breakdown voltage is specified in this standard. (Any value for this property should be given in the purchase contract, but a typical value is 1,5 kV/mm wall thickness, although a linear relationship cannot be assumed.) However, it serves to provide mechanical protection to circuit components such as wires, sleeves, and flat cable over which it is applied as a containing wrap or harness. 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.

Gaines isolantes souples - Partie 3: Spécifications pour types particuliers de gaines - Feuilles 343 à 345: Gaines expansibles tressées, en éthylène chlorotrifluoroéthylène (E-CTFE), tissées, non revêtues

Donne les prescriptions relatives aux gaines ayant comme propriété d'agrandir leur diamètre intérieur quand elles sont compressées longitudinalement, pour revenir ensuite à leur diamètre initial après suppression de la force de compression. Ces gaines expansibles tressées, tissées, non revêtues, sont faites de fibres monofilamentaires d'éthylène chlorotrifluoroéthylène (E-CTFE) traitées de manière à assurer les aptitudes mécaniques au comportement exposées ci-dessus. Les gaines peuvent être utilisées à des températures allant jusqu'à 155 °C. Ces gaines sont normalement fournies en diamètres intérieurs compris entre 6 mm et 63 mm, avec trois niveaux d'épaisseur de paroi (mince (feuille 343), moyenne (feuille 344) et épaisse (feuille 345)). Du fait de leur constitution aérée, ces gaines sont normalement utilisées pour assurer une isolation par épaisseur d'air; c'est pourquoi cette norme ne spécifie pas d'exigence pour la tension de claquage. (Il convient que toute valeur intéressant cette propriété soit indiquée dans le contrat d'achat, la valeur type étant de 1,5 kV/mm d'épaisseur de paroi, bien qu'un rapport linéaire ne puisse être assuré.) Toutefois, ces gaines servent à procurer une protection méca-nique à des composants de circuits comme les conducteurs, les gaines et les câbles en nappe autour desquels ces gaines sont montées comme un enveloppement ou filet de maintien. Les matériaux qui sont conformes à cette spécification satisfont à des niveaux de performances établis. Cependant, il convient que le choix d'un matériau par un utilisateur et pour une application particulière soit fondé sur les prescriptions réelles nécessaires pour obtenir les performances satisfaisantes pour cette application, et non fondé sur cette seule spécification.
