EN 6113:2015 - Aerospace series - Circuit breaker, connecting and attachment hardware

Overview

SIST EN 6113:2015 is a European Standard developed by CEN that specifies the connecting and attachment hardware for circuit breakers within the aerospace industry. This standard ensures high-quality, reliable components such as connecting screws, lockwashers, and attachment nuts that comply with rigorous aerospace requirements. Approved in 2015, SIST EN 6113:2015 harmonizes hardware specifications across CEN member countries, contributing to safer and more efficient aerospace electrical systems.

Key Topics

  • Scope and Purpose
    The standard defines the design, dimensions, materials, and mechanical properties of hardware used to connect and attach aerospace circuit breakers, ensuring conformity and interchangeability in aerospace equipment.

  • Connecting Screw

    • Thread: 0.1640-32UNC-3A as per MIL-S-8879
    • Cross recess: ISO 4757 type H, No.2
    • Material: Steel with rupture resistance between 860 MPa and 1000 MPa
    • Protection: Nickel plating with a minimum thickness of 5 µm

  • Lockwashers

    • Connecting lockwasher: Two wave corrugated washer made from CuBe alloy with 350 HV to 410 HV hardness
    • Attachment lockwasher: M12DIC type internal overlapping teeth, steel with 400 HV to 480 HV hardness

  • Attachment Nut

    • Material: Aluminium alloy with black sulphur anodizing for corrosion protection
    • Sizes: M12 × 0.75 mm and M12 × 1 mm threads with specified dimensional tolerances

  • Hardware Kits
    Kits comprising connecting screws, lockwashers, and attachment nuts are defined with specific part numbers for ease of ordering and replacement.

  • Marking and Identification
    All hardware kits and spare parts must be marked in accordance with EN 2424, ensuring traceability and compliance with aerospace product marking standards.

Applications

SIST EN 6113:2015 hardware components are critical for:

  • Aerospace Electrical Systems
    Providing standardized and durable connecting hardware for circuit breakers in aircraft and space vehicles electrical circuits.

  • Circuit Breaker Assembly & Maintenance
    Used by aerospace manufacturers and maintenance providers to ensure secure fastening of circuit breakers with components adhering to precise dimensional and material specifications.

  • Quality Assurance and Safety Compliance
    Facilitating adherence to aerospace industry quality regulatory frameworks, minimizing risks associated with electrical faults from hardware failure.

  • Spare Parts Management
    Defined hardware kits improve logistics and inventory management of replacement parts across aerospace operators and suppliers.

Related Standards

  • EN 2424 – Aerospace series marking of aerospace products, providing requirements for marking hardware parts for identification and traceability
  • MIL-S-8879 – Specification for screw threads with increased minor diameter used in aerospace hardware
  • ISO 4757 – Defines cross recess types for screws used in precision assembly
  • TR 3775 – Aerospace series materials specification for bolts and pins, defining mechanical and material properties of steel components
  • MIL-B-87114 – General specifications for bolts, applicable to technical properties of fasteners in aerospace environments

SIST EN 6113:2015 plays a key role in standardizing connecting and attachment hardware for aerospace circuit breakers, improving component compatibility, safety, and overall system reliability. Aerospace engineers, manufacturers, and maintenance providers rely on this standard to meet the stringent technical demands of aerospace electrical systems.
