Overview

EN 50290-2-36:2016 defines specific requirements for crosslinked silicone rubber (SiR) compounds intended for the insulation of fire-resistant communication cables. This Part 2-36 must be read together with EN 50290-2-20 and other applicable product standards. The standard sets compound and cable test expectations and clarifies the data a raw material supplier should provide to demonstrate suitability and compliance.

Key details from the standard include:

• Compound type: Crosslinked SiR with a maximum operating temperature of 180 °C (Table 1).
• Supplier responsibility: Compound suppliers provide granule or moulded plaque test data so cable manufacturers can include the material in supply specifications.

Key Topics

The standard focuses on measurable properties and required test methods. Important topics covered are:

• Compound test requirements (Table 2)

  • Corrosivity of gases (EN 60754-2): pH ≥ 4.3 and conductivity ≤ 10 μS/mm.
  • Halogen acid content (EN 60754-1, EN 60684-2): HCl/HBr ≤ 0.5%, HF ≤ 0.1%.
  • Density (EN 60811-606): to be reported by the supplier.

• Cable-level tests (Table 3)

  • Mechanical properties before ageing (EN 60811-501): tensile strength median ≥ 5 MPa, elongation at break median ≥ 150%.
  • After thermal ageing (EN 60811-401; ageing 200 ±3 °C for 10 × 24 h): tensile strength median ≥ 4 MPa, elongation ≥ 120%.
  • Hot set (EN 60811-507; 250 ±3 °C, 15 min, 20 ±0.5 N/cm²): elongation under load max 100%, residual elongation max 25%.

• Normative references: EN 50290-2-20, EN 60684-2, EN 60754-1/2, EN 60811-series and other IEC-derived test methods.

Applications

This standard is intended for:

• Manufacturers and formulators of SiR insulation compounds for fire-resistant communication and coaxial cables.
• Cable designers and OEMs who need to specify insulation materials with verified thermal stability, low corrosivity, and defined mechanical performance after ageing.
• Raw material suppliers that must supply test reports and guaranteed values so cable makers can include the compound in product specifications.

Practical benefits include consistent material selection, reduced risk of corrosive combustion products in service, and documented evidence to support regulatory and contract compliance.

Related Standards

EN 50290-2-36:2016 is part of the EN 50290 family and references several test method standards that are essential for application:

• EN 50290-2-20 - Common design rules and construction - General
• EN 60684-2, EN 60754-1, EN 60754-2 - Gas evolution and halogen/acid tests
• EN 60811-401 / -501 / -507 / -606 - Non-metallic materials test methods (thermal ageing, mechanical, hot set, density)

For procurement and compliance, always specify the referenced test methods and report the compound values listed in Tables 2 and 3. Any deviations or HSE issues should be identified by the raw material supplier and resolved with the cable manufacturer in accordance with EN 50290-2-20.
