Описание (английский):

ISO 4091:2003 gives definitions and specifies tests and requirements for connectors used for the electrical connection of towing and towed road vehicles. It is applicable to connectors of all types used for this purpose, as specified in ISO 1185, ISO 1724, ISO 3731, ISO 3732, ISO 7638-1, ISO 7638-2, ISO 11446 and ISO 12098.

Overview

ISO 4091:2003 - Road vehicles - Connectors for the electrical connection of towing and towed vehicles - Definitions, tests and requirements - defines terminology and specifies tests and performance requirements for electrical connectors used between towing and towed road vehicles. It is the third edition (2003) and applies to connector types referenced in related ISO standards (see Related Standards). ISO 4091 does not set detailed pin layouts or dimensions - those are specified in the connector-specific standards - but it establishes the functional, mechanical and environmental test requirements that ensure safe, reliable electrical connections in towing applications.

Key topics and technical requirements

ISO 4091 covers a comprehensive test program and requirements, including:

Terms and definitions for connector, contact, plug, socket, ejector, etc., to ensure consistent interpretation.

General test sequencing and conditioning (e.g., preconditioning at 23 °C ± 5 °C and 45–75 % RH for 24 h; tests commence with unused, clean samples; no added lubrication).

Mechanical tests: visual examination, dimensional checks, connection & disconnection forces (25–100 mm/min test speed), locking device operation (locking lever ≤ 120 N; twist-lock torque ≤ 3.5 N·m), ejector force (35–75 N), cable retention and locking strength (1 000 N applied), lateral strength at low temperature (torque tests at −40 °C).

Electrical performance: current-carrying capacity, connection resistance/voltage drop, current cycling, and withstand voltage tests.

Environmental durability: influence of water, temperature/humidity cycling, salt spray (corrosion), vibration, drop, endurance and protection against dust (IP-related considerations).

Sample preparation and post-test requirements: how samples are mounted, cable simulation (test rod diameters specified), and pass/fail criteria (no cracking, excessive deformation or water ingress).

Applications and who uses it

ISO 4091 is essential for:

Vehicle manufacturers (OEMs) specifying reliable towing electrical interfaces for trailers and caravans.

Connector and harness suppliers designing and validating plugs, sockets and locking mechanisms.

Test laboratories and quality engineers conducting compliance testing against mechanical, electrical and environmental criteria.

Fleet operators, trailer manufacturers and regulators seeking standardized, safe towing electrical connections to reduce failures and improve interoperability.

Using ISO 4091 helps ensure connector durability, electrical integrity and interchangeability between towing and towed vehicles across international markets.

Related Standards

ISO 4091 is intended to be used with connector-specific standards such as:

Keywords: ISO 4091, towing connectors, electrical connectors, towing and towed vehicles, connector tests, connector requirements, trailer electrical connector, vehicle harness testing.
