Overview
ISO 8056-4:1987 establishes the dimensional requirements for crimp-type butt connectors used with nickel-chromium and nickel-aluminium thermocouple extension cables in aircraft applications. This part of the ISO 8056 series focuses on connectors intended for temperature indicator and control systems in aviation environments, supporting flexible thermocouple extension cables at a nominal voltage of 600 V and a maximum frequency of 2,000 Hz. The standard specifies the acceptable conductor size range and cable insulation range to ensure compatibility and optimal performance in demanding operational conditions.
Key Topics
- Connector Dimensions: Provides precise measurements for crimp-type butt connectors, ensuring interoperability and compatibility across manufacturers and installations.
- Material Compatibility: Covers connectors used with nickel-chromium and nickel-aluminium thermocouple extension cables, which are commonly used for their stability and resistance to high temperatures.
- Electrical Ratings: Specifies usage with systems up to 600 volts and 2,000 Hz, aligning with typical aircraft temperature sensor and control system requirements.
- Conductor and Insulation Range: Defines the permissible conductor sizes (in mm² and AWG) and corresponding cable insulation diameters, facilitating secure and reliable electrical connections.
- Color Coding: Addresses sleeve color coding by material type (e.g., green for Ni-Al, grey for Ni-Cr) to assist with correct assembly and identification.
Applications
The requirements outlined in ISO 8056-4:1987 are vital across several aviation sectors, including:
- Temperature Monitoring Systems: Ensures reliable electrical connections in temperature indicator and control systems critical to aircraft operation and safety.
- Flexible Cable Installations: Improves the durability and lifespan of flexible nickel-based thermocouple extension cables by specifying connector compatibility.
- Maintenance and Retrofitting: Provides standardized dimensions to enable easy replacement and maintenance of thermocouple extension cables and connectors throughout an aircraft's lifecycle.
- Compliance and Quality Assurance: Assists aircraft manufacturers, suppliers, and maintenance organizations in meeting international quality and performance standards, supporting regulatory compliance and operational reliability.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 8056-4 was prepared by Technical Committee ISO/TC 20,
Aircraft and spare vehicles.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
