This document specifies the CXPI data link and physical layers conformance test plan, which tests the data link layer using the service interface parameters reported by the physical layer and submitted to higher OSI layers. The physical layer uses additional test and measurement equipment, which is described in the individual conformance test cases (CTC).

The data link layer and physical layer conformance test plan contains the following descriptions:

⎯ concept of operation conformance test plan;

⎯ data link layer protocol conformance test plan;

⎯ physical layer conformance test plan; and

⎯ error detection conformance test plan.

This document shall provide all necessary technical information to ensure that test results will be identical even on different test systems, provided that the particular test suite and the test system are compliant to the content of this document.

This part of ISO 8820 specifies fuse-links with tabs (blade-type) Type L (high current miniature) for use in road vehicles. It establishes, for this fuse-link types, the rated current, test procedures, performance requirements and dimensions.

This part of ISO 8820 is applicable for fuse-links with a rated voltage of 32 V, a current rating of ≤ 60 A and a breaking capacity of 1 000 A intended for use in road vehicles.

This part of ISO 8820 is intended to be used in conjunction with ISO 8820-1 and with ISO 8820-2. The numbering of its clauses corresponds to that of ISO 8820-1 whose requirements are applicable, except where modified by requirements particular to this part of ISO 8820.

This document specifies the mechanical, electrical/electronic and pneumatic characteristics of a fully automated fifth wheel coupling system to ensure interchangeability between a towing vehicle and a coupled semi-trailer(s) with 24 V nominal supply voltage. The two vehicles together constitute an articulated vehicle or are part of a vehicle combination.

This document also supports the smooth introduction of fully automated fifth wheel coupling systems in the market. It specifies features necessary for mixed mode operation; i.e. the combination of a fully automated coupling system (FACS) equipped towing vehicle with a conventional semi-trailer, and vice versa, the combination of a conventional towing vehicle with a FACS-equipped semi-trailer.

This International Standard gives the specifications — requirements and test methods — for non-petroleum-base fluids used in road-vehicle hydraulic brake and clutch systems that are designed for use with such fluids and equipped with seals, cups or double-lipped type gland seals made of styrene-butadiene rubber (SBR) and ethylene-propylene elastomer (EPDM).

This document specifies a method for comparing simulation results from a vehicle model to measured test data for an existing vehicle according to closing-curve tests as specified in ISO 11026:2011. The purpose of the validation is to demonstrate that the vehicle dynamics simulation, combined with an integrated electronic stability control (ESC) system, can predict the roll and yaw stability behaviour of a physical vehicle, including the ESC system interventions, during a closing-curve test. The simulation method can be either hardware-in-the-loop (with the original electronic control unit (ECU) on a HiL test stand) or software-in-the-loop, based on a software code generated from the same source as for the ECU in the real vehicle. The standard applies to heavy vehicles, including commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with a maximum weight above 3.5 tonnes and buses and articulated buses with a maximum weight above 5 tonnes, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4).
