Overview

ISO 5066-1:1986 specifies the operating characteristics and test conditions for 2A and 3A hermetically sealed monostable electrical relays intended for use in aircraft. Developed by the International Organization for Standardization (ISO), this standard focuses on essential performance, construction, and service environment criteria without mandating a specific relay model or exact dimensions. Instead, it establishes permissible variant limits within an individual product range and provides a foundational specification framework for both manufacturers and end users dealing with aircraft electrical relays.

Key Topics

Operating Characteristics: Outlines the requirements for relay performance, including definitions, operating voltages and currents, insulation and contact resistance, make/break times, and bounce behavior.

Test Conditions: Specifies the environmental and test parameters under which relays must function, such as temperature ranges (-65°C to +125°C), altitude capability (up to 24,000m), humidity, atmospheric pressure, and vibration/shock resistance.

Mechanical and Electrical Construction: Describes general construction principles, including hermetic sealing, use of inert gas, coil design, insulation, and contact systems.

Quality and Production Testing: Sets out procedures for sample selection, type approval, and production quality assurance to ensure reliability and performance consistency.

Marking Requirements: Details mandatory product information to be marked for traceability and user reference, such as manufacturer ID, voltage, and coil resistance.

Applications

ISO 5066-1:1986 serves as a crucial reference for:

Aircraft Design and Maintenance: Establishes a baseline for selecting and assessing relays used in critical electrical and avionics applications, supporting both OEMs and maintenance providers in ensuring equipment safety and reliability.

Relay Manufacturers: Provides clear guidance for designing relays that meet internationally recognized performance standards, facilitating market access and product acceptance in the aviation sector.

Testing Laboratories and Certifying Agencies: Lays out standardized procedures for environmental, electrical, and mechanical testing to assess conformity, ensuring consistent product qualification and certification processes.

Procurement and Quality Assurance: Assists purchasing agents and quality engineers in specifying relay requirements that ensure compatibility and reliability within aerospace systems.

Implementing ISO 5066-1 helps achieve higher safety, durability, and interoperability for aircraft electrical systems by standardizing crucial aspects of relay design and performance.

Related Standards

Several other international standards complement ISO 5066-1:1986 and help ensure a cohesive approach to aircraft electrical component specification:

ISO 5066-2: Aircraft - Hermetically sealed monostable electrical relays, 2A and 3A - Part 2: Type approval tests Details laboratory and qualification tests needed for relays to be deemed compliant with ISO 5066.

ISO 1540: Aerospace - Characteristics of aircraft electrical systems Defines key parameters of aircraft electrical systems relevant to component selection and integration.

ISO 2315: Aircraft - Two- and four-pole sealed electromagnetic relays, 2A and 3A - Clearance and fixing dimensions Provides standardized fixing and clearance dimensions for these relays.

ISO 7137: Aircraft - Environmental conditions and test procedures for airborne equipment Specifies the environmental test conditions applicable to airborne electronic equipment, often referenced in relay testing.

Practical Value

Adopting ISO 5066-1 ensures that hermetically sealed monostable relays meet the rigorous demands of the aviation industry, improving operational safety and reliability. The standard is vital for manufacturers aspiring to global recognition and for operators aiming to maintain high service standards within aircraft electrical systems. By harmonizing relay specifications and test methods, ISO 5066-1:1986 supports international trade and interoperability in the aerospace sector.
