EN 60684-3-136:1998

Overview

EN 60684-3-136:1998 specifies requirements for non-heat-shrinkable, extruded sleeving manufactured from compounds based on fluorosilicone rubber. This sheet (Part 3, Sheet 136) of the EN 60684 series covers general-purpose insulating sleeving intended for electrical and component protection. The standard aligns with IEC 60684-3-136:1997 and is classified under ICS 29.035.20 (Plastics and rubber insulating materials).

Key scope details provided in the standard include:

• Sleeving produced by extrusion from fluorosilicone compounds
• Availability of internal diameters up to 25 mm
• Wall thickness range from 0.1 mm to 2.0 mm

The document is presented in multiple national-language adoptions (for example SIST EN 60684-3-136:2001) and is intended to guide manufacturers, specifiers and purchasers on dimensional and material definitions for this specific sleeving type.

Key Topics

• Material definition: Identification of fluorosilicone-based compound as the base material for the extruded sleeving type covered by this sheet.
• Dimensional ranges: Standardized guidance on internal diameters (up to 25 mm) and wall thicknesses (0.1–2.0 mm) to support selection and procurement.
• Product type: Clarifies that the sleeving is non-heat-shrinkable and produced by extrusion.
• Classification: Links to the EN 60684 series and the IEC counterpart, aiding harmonized use across markets.

Applications

This standard is primarily useful for engineers, specifiers and procurement teams working with insulating sleeving where a fluorosilicone extruded product is required. Typical application considerations include:

• Electrical insulation for wiring harnesses and assemblies where a stable extruded sleeving form factor is desired
• Protection of components and cable runs against abrasion and environmental exposure in general-purpose contexts
• Specification and purchasing: Using the standard to define required ID and wall thickness ranges in procurement documents

Practical benefits of following EN 60684-3-136 include consistent dimensional specifications across suppliers and clearer material identification for sourcing and quality control. The standard supports interoperability between manufacturers and helps ensure products meet defined expectations for form and composition.
