SIST EN 3660-037:2010

Overview

SIST EN 3660-037:2010 is a European product standard developed by the Aerospace and Defence Industries Association of Europe (ASD-STAN) and published under the CEN framework. This standard specifies requirements for the bushing strip, elastomer, style Z, designed for cable outlets used with circular and rectangular electrical and optical connectors in aerospace applications. The document ensures consistent quality and interoperability across aerospace components by defining the physical and material characteristics, test methods, and designation protocols.

The bushing strip covered under this standard operates reliably within a wide temperature range, from -65 °C to 200 °C, making it suitable for harsh aerospace environments. It complements specific cable outlet types outlined in EN 3660-002, supporting consistent integration into aerospace electrical and optical connector systems.

Key Topics

• Product Definition
  The standard precisely defines the design and application of the bushing strip, style Z, as an elastomer component for cable outlets associated with aerospace connectors.

• Material Specifications
  The bushing strip is made from elastomer, chosen for its durability and resistance to extreme temperature fluctuations typical in aerospace conditions.

• Temperature Range
  Performance is guaranteed within temperatures from -65 °C to 200 °C, catering to the wide thermal demands of aerospace hardware.

• Dimensional Requirements
  Detailed dimensions and mass values are provided (in millimetres and grams), ensuring compatibility with associated cable outlets (EN 3660-020 and EN 3660-021) and allowing for precise engineering and installation.

• Testing and Qualification
  The standard mandates specific techniques for testing and qualification to verify performance, focusing on integration with the cable outlet accessories.

• Designation System
  A structured part numbering and designation system simplifies identification and helps maintain traceability throughout manufacturing and supply chains.

Applications

SIST EN 3660-037:2010 is primarily targeted at aerospace manufacturers and suppliers involved in designing and assembling electrical and optical connector systems. Key applications include:

• Aerospace Electrical Systems
  Enhances durability and environmental protection for cable outlets on electrical connectors used in aircraft and spacecraft.

• Optical Connector Assemblies
  Provides reliable cable outlet sealing to maintain optical signal integrity in extreme conditions.

• Harsh Environment Cabling
  Ensures mechanical protection and strain relief in aerospace wiring systems exposed to high vibration, temperature extremes, and environmental stress.

• Connector Accessories Manufacturing
  Standardizes accessory components, enabling interchangeability and streamlined production for aerospace connector systems.

Related Standards

SIST EN 3660-037:2010 works in conjunction with other standards in the Aerospace series for cable outlet accessories, including:

• EN 3660-001 – Technical specifications for cable outlet accessories for circular and rectangular electrical and optical connectors.

• EN 3660-002 – Index of product standards covering cable outlet accessories, providing classifications and references.

• EN 3660-020 – Cable outlet, style A, straight, unsealed, self-locking with clamp strain relief.

• EN 3660-021 – Cable outlet, style A, 90°, unsealed, self-locking with clamp strain relief for EN 3645 connectors.

These standards collectively ensure that connector accessories meet rigorous aerospace industry requirements for quality, safety, and functionality.
