Overview

EN 4056-005:2023 is a European standard under the Aerospace series focusing on plastic cable ties with metallic locking devices used in aircraft cable harnesses. It covers products designed to operate reliably under controlled tension within temperature ranges from -65 °C to 105 °C and -65 °C to 150 °C. Developed by the European Committee for Standardization (CEN) and prepared by ASD-STAN, this standard ensures the high performance, safety, and compliance of cable ties essential for aerospace electrical systems.

The standard complements EN 4056-001:2015, which provides the overall technical specifications for cable ties in aerospace applications. Together, these form a robust framework to standardize cable tie products for enhanced reliability in harsh operational environments typical of aerospace systems.

Key Topics

Product Characteristics

• Materials: Manufactured from specialized plastics combined with metallic locking devices to ensure durability and secure fastening.
• Temperature Rating: Two types based on operating temperature: Type 1 (-65 °C to 105 °C) and Type 2 (-65 °C to 150 °C).
• Flammability Classes: Class 1 and Class 2, defining fire behavior and self-extinguishing properties.

Physical Dimensions and Strength

• Defined dimensions including length, width, thickness, and head size for various size codes (P to V).
• Minimum loop tensile strengths specified per size to guarantee mechanical reliability.

Smoke and Toxicity Requirements

• Complies with EN 2825 and EN 2826 for low smoke density and toxicity under fire conditions.
• Limits on harmful gas emissions such as Hydrogen Fluoride, Hydrogen Chloride, Hydrogen Cyanide, Sulphur Dioxide, and Carbon Monoxide.

Durability and Environmental Resistance

• UV resistance tested in accordance with EN 4057-307 to withstand prolonged exposure.
• Resistance to fluids, heat aging, salt mist, and vibration endurance tests ensure long-term durability in aerospace environments.

Application and Usage

• Mandatory use of calibrated tensioning tools conforming to MS 90387 and EN 4057-407 to apply cable ties under controlled tension.
• Maximum application force guidance ensures proper installation without damaging cable harnesses.

Quality Control

• Quality assurance processes align with EN 4056-001:2015, providing consistent product performance and traceability.

---

Applications

EN 4056-005:2023 cable ties are specifically designed for aircraft cable harnesses where secure and reliable fastening is critical for safety and functionality. Their use includes:

• Securing electrical cables in cockpits, avionics, and power distribution systems.
• Harness bundling in commercial, military, and space aerospace vehicles requiring compliance with stringent environmental conditions.
• Situations demanding resistance to extreme temperatures, UV exposure, corrosive atmospheres, and fire safety requirements.
• Applications where controlled application force is necessary to avoid damaging sensitive aerospace wiring.

---

Related Standards

To ensure full compatibility and compliance within aerospace electrical systems, EN 4056-005:2023 is used in conjunction with several related standards:

• EN 4056-001:2015 – General technical specifications for cable ties in aerospace harnesses.
• EN 4057 (Parts 1-9) – Test methods covering mechanical performance, environmental resistance, and material properties.
• EN 2825 & EN 2826 – Standards for burning behavior, smoke density, and toxicity of non-metallic materials in aerospace applications.
• MS 90387 – Specifications for the tensioning tool used in cable tie application.

These interconnected standards enable manufacturers and aerospace engineers to comprehensively assess cable ties against operational and safety criteria.
