Overview

ISO 5066-2:1986, developed by the International Organization for Standardization (ISO), sets forth the type approval testing methods for hermetically sealed monostable electrical relays rated at 2A and 3A for use in aircraft applications. This standard is the second part of a two-part series, complementing ISO 5066-1, which covers the operating characteristics and test conditions for these relays. ISO 5066-2 is essential for manufacturers, suppliers, and regulators in the aerospace industry, providing clear approval procedures to ensure relays meet stringent reliability, safety, and performance criteria under demanding environmental and electrical conditions.

Key Topics

Scope and Applicability: Focused on hermetically sealed monostable electrical relays used in aircraft, specifically for 2A and 3A ratings.

Reference to ISO 5066-1: All operating characteristics, conditions, and details about order of tests are stipulated in the companion standard, ISO 5066-1.

Sample Preparation and Preliminary Checks:

Examination of appearance, marking, mass, and dimensions.
Conformance to referenced standards for physical characteristics.

Comprehensive Test Methods:

Resistance voltage, insulation resistance, contact and coil resistance.
Performance characteristics such as pick-up/drop-out voltages, make/break times, and contact bounce.
Endurance, overload, moisture, hermetic seal integrity, temperature cycling, humidity, salt spray, mechanical shock, vibration, acceleration, solderability, outlet strength, and magnetic interference.

Order of Test Execution: Tests No. 1 to 20 are to be conducted in a prescribed sequence, ensuring systematic evaluation.

Applications

Relays covered by ISO 5066-2:1986 play a critical role in:

Aircraft Electrical Systems: Used extensively in flight control, avionics, lighting, safety systems, and power distribution.

Regulatory Compliance: Assists aerospace manufacturers in meeting international quality and safety benchmarks for electrical components.

Product Qualification: Essential during design approval, quality audits, and supplier assessments when introducing new or modified relay types into aircraft systems.

Reliability Assessment: By adhering to these standardized tests, aircraft operators and maintenance organizations secure high reliability in electrical switching devices, directly impacting the overall safety and performance of aircraft operations.

Related Standards

ISO 5066-1: Aircraft - Hermetically sealed monostable electrical relays, 2A and 3A - Part 1: Operating characteristics and test conditions. This part defines the performance requirements and test environment for the relays evaluated under ISO 5066-2.

ISO 2315: Specifies clearance and mounting dimensions for two- and four-pole sealed electromagnetic relays, referenced for dimension checks in ISO 5066-2.

Other Aircraft and Electrical Relay Standards: Compliance with ISO 5066-2 supports broader conformity with aviation safety standards and quality control across international markets.

Benefits of ISO 5066-2 Type Approval Testing:

Ensures electrical relays achieve consistent performance under operational and environmental stresses found in aviation.

Minimizes risk of relay failure in critical aircraft systems.

Facilitates international trade and regulatory acceptance of relay components.

For any organization working with aircraft electrical relays, adherence to ISO 5066-2:1986 is a key step in achieving product reliability and international compliance.
