This International Standard defines different multiple-vehicle combinations (vehicle combinations with more than one coupling point) and the formulae to calculate the requirement of performance for the coupling equipment used in those vehicle combinations. Vehicle categories concerned are N2, N3, O3, and O4.

NOTE For these vehicle combinations, the formulae in this International Standard override the formulae in References [6], [7], [8], and [9] that apply to vehicle combinations with one coupling point only. However, the capability of the coupling equipment is  still determined through tests as defined in References [6], [7], [8], and [9].

This International Standard specifies the characteristics necessary for the mounting and interchangeability of clevis couplings on the frame (cross member, drawbeam or mounting bracket) of towing vehicles for trailers.

This International Standard is applicable to clevis couplings intended for connection to trailers equipped with a drawbar eye on the drawbar of the trailer.

Characteristics not specified are left to the discretion of the component manufacturer.

This document specifies:

— requirements on the physical layer at system level,

— requirements on the interoperability test set-ups,

— interoperability test plan that checks the requirements for the physical layer at system level,

— requirements on the device-level physical layer conformance test set-ups, and

— device-level physical layer conformance test plan that checks a set of requirements for the OSI

physical layer that are relevant for device vendors.

The interoperability test plan checks the physical layer system requirements specified in this document

and in ISO/IEC/IEEE 8802-3:2017/Amd 9:2018.

This test plan is structured in four different test groups, attending to the kind of system requirements

that covers:

— link status, that includes the tests that check the status of the link by using the content of the available

registers and its accuracy with the real status of the link,

— link-up, that includes the tests that check the time that the IUT reaches a reliable link status from

certain state,

— channel quality, that includes the tests that check the quality of the optical channel by using the

content of the available registers and its accuracy with the real quality of the optical channel, and

— wake-up and sleep, that includes the tests that check that the transmission and reception of the wake up

and sleep events.

The requirements covered by the device-level physical layer conformance test plan are specified in the

ISO 21111 series and in ISO/IEC/IEEE 8802-3:2017/Amd 9:2018.

This test plan is structured in four different test groups, attending to the test set-up required:

— high-attenuation channel,

— low-attenuation channel,

— optical IUT transmitter measurements, and

— wake-up and synchronised link sleep.
