Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheets 121 to 124: Extruded silicone sleeving

Gives the requirements for four types of non-heatshrinkable sleeving, extruded from silicone elastomer. These sleevings are normally available with internal diameter up to 25 mm and in a range of wall thicknesses between 0,1 mm and 2,0 mm. National standards may select a restricted list of preferred combinations of internal diameter and wall thickness.

Donne les prescriptions pour quatre types de gaine en élastomère de silicone extrudé, non thermorétractables. Ces gaines sont normalement fournies avec des diamètres intérieurs allant jusqu'à 25 mm et dans des gammes d'épaisseur de paroi comprises entre 0,1 mm et 2,0 mm. Les normes nationales peuvent choisir une liste réduite de combinaisons préférentielles pour les diamètres intérieurs et les épaisseurs de paroi.

Overview

EN 60684-3-121 to 124:2001 (CLC) covers specifications for extruded silicone flexible insulating sleeving. It is Part 3 of the EN 60684 series and defines requirements for four types of non‑heatshrinkable sleeving made from silicone elastomer. The standard is aligned with IEC 60684‑3‑121 to 124:2001 and is intended for use where flexible, thin‑walled insulating protection is needed.

Key Topics

• Scope and classification - Defines the four specific non‑heatshrinkable sleeving types within Sheets 121–124.
• Material - Sleeving extruded from silicone elastomer (silicone sleeving), with properties appropriate for flexible insulating applications.
• Dimensions - Typical availability up to 25 mm internal diameter and wall thicknesses in the range 0.1 mm to 2.0 mm.
• Preferred combinations - Notes that national bodies may select a restricted list of preferred internal diameter / wall thickness combinations for procurement and regulation.
• Specification structure - Part 3 provides the individual type specifications that complement the general requirements in the EN 60684 series (e.g., type definitions, dimensional limits and type‑specific requirements).

(Note: the standard text itself specifies the precise requirements for each sleeving type. This summary does not reproduce all test methods or numeric performance limits.)

Applications

• Wire and cable protection - Insulating and protecting wire assemblies, harnesses and small-diameter cables where flexible, thin silicone sleeving is required.
• High‑temperature or flexible environments - Typical uses include electronics, appliance wiring, automotive secondary circuits and industrial connectors where silicone elastomer’s flexibility and temperature tolerance are beneficial.
• Manufacturing and procurement - Useful for sleeving manufacturers, OEMs, buyers specifying compliant products, and test laboratories verifying conformity.

Who Should Use This Standard

• Product designers and electrical engineers specifying insulating sleeving
• Manufacturers of silicone extruded sleeving and insulated components
• Procurement professionals selecting standardized sleeving sizes and types
• Compliance officers and test labs aligning products with EN/IEC requirements
