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.

Overview
SIST EN 60684-3-343 to 345:2004 is a European standard issued by CLC that specifies the requirements for expandable braided ethylene chlorotrifluoroethylene (E-CTFE) textile sleeving in uncoated form. This flexible insulating sleeving is designed to expand its internal diameter when compressed longitudinally and then return to its original size once the compressing force is released. It is made from E-CTFE monofilament yarns, offering mechanical resilience and flexibility suitable for electrical insulation and mechanical protection purposes.
These sleeving products are rated for use at temperatures up to 155 °C and come in internal diameters ranging from 6 mm to 63 mm. They are available in three wall thicknesses: thin (sheet 343), medium (sheet 344), and thick (sheet 345). The sleeving is commonly used to provide air-space insulation rather than dielectric insulation, emphasizing its role in mechanical protection for wires, sleeves, and flat cables.
Key Topics
- Expandable Design: The sleeving can expand when compressed longitudinally and return to its original diameter, allowing for flexible installation and secure fitting over cables and components.
- Material Composition: Constructed from ethylene chlorotrifluoroethylene (E-CTFE) monofilament yarns, providing chemical and thermal resistance.
- Temperature Rating: Suitable for continuous use up to 155 °C, supporting high-temperature electrical applications.
- Size and Thickness Variants:
- Thin wall (Sheet 343) – minimum 0.30 mm thickness
- Medium wall (Sheet 344) – minimum 0.50 mm thickness
- Thick wall (Sheet 345) – minimum 0.75 mm thickness
- Colour Options: Available in multiple colours including black, white, brown, red, orange, yellow, green, blue, grey, and natural (unpigmented).
- Mechanical Protection: Provides robust mechanical protection without focusing on electrical breakdown voltage, suited for protecting cables from abrasion and handling stresses.
- Open Construction: Designed to offer air-space insulation, enhancing heat dissipation in electrical installations.
Applications
- Electrical Wiring Harnesses: Used extensively for wrapping and protecting wiring harnesses in industrial machinery, transport vehicles, and electronic devices.
- Mechanical Insulation: Ideal for protecting sensitive wire bundles against mechanical damage, cuts, and abrasions in harsh environments.
- High-Temperature Environments: Suitable for use in applications where exposed components require insulation at elevated temperatures up to 155 °C.
- Chemical Resistance: Applicable in environments exposed to common fluids such as fuels, hydraulic fluids, oils, and cleaning solvents without degradation.
- Aerospace and Automotive: Preferred in aerospace and automotive sectors where lightweight, flexible, and durable sleeving is essential with resistance to fluids and temperature fluctuations.
- Industrial Electrical Equipment: Protects cables and flat cables in control panels, switchgear, and other electrical equipment requiring non-conductive mechanical safeguards.

Practical Considerations
- When selecting E-CTFE expandable sleeving according to SIST EN 60684-3-343 to 345:2004, users should assess the exact mechanical, thermal, and chemical requirements of the application.
- The standard does not specify breakdown voltage due to the sleeving’s open construction, so electrical insulation properties must be confirmed via contractual agreements.
- Wall thickness selection (thin, medium, thick) should correspond to the level of mechanical protection and insulation performance required.
- Careful measurement of internal diameter is recommended due to the expansion properties and open textile structure.
- Compatibility with fluids such as gasoline, kerosene, hydraulic fluids, oils, alcohols, de-icers, and cleaning solvents can enhance the sleeving's longevity in challenging environments.
By adhering to SIST EN 60684-3-343 to 345:2004, manufacturers and users of flexible insulating sleeving can ensure reliable mechanical protection combined with thermal resilience and chemical resistance, meeting the demands of modern electrical and electronic applications. This standard provides a trusted framework for ensuring product quality and performance in various industrial sectors.
