Reading part 1 of this standard will provide an overview about the entire standard and how it applies to the automotive industry.
This part of the standard 18541 includes a transposition of the contents in parts 1-4 to heavy duty motor vehicles as defined in regulation (EC) 595/2009 Article 2.
The parts of the standard 18541-1, -2, -3, -4 focus on the access to automotive repair and maintenance information for passenger cars and light commercial vehicles.
Remote Diagnostic Support is a specific requirement for Access to RMI for HD vehicles. It will be addressed separately in a new part of the standard 18541 (currently under definition, see NWIP N421).
The standard 18542 is a complementary standard that defines the ‘Standardized RMI terminology’ and consists of two parts:
   Part 1: General information and use case definition
   Part 2: Standardized process implementation requirements and Registration Authority
The standardized RMI terminology is contained in a so-called ‘Digital Annex’.

This document focus on the access to automotive repair and maintenance information for
— heavy duty motor vehicles as defined in regulation (EC) 595/2009 Article 2;
— engines and after-treatment systems (family) if they are type-approved as a separate technical unit, e.g. according to Directive 2007/46/EC.
This document includes a transposition of the standards ISO 18541-1:2014, ISO 18541-2:2014, ISO 18541-3:2014, and ISO 18541-4:2015 to these vehicle types and systems. The standards ISO 18541-1:2014, ISO 18541-2:2014, ISO 18541-3:2014, and ISO 18541-4:2015 focus on the access to automotive repair and maintenance information for passenger cars and light commercial vehicles.
Remote Diagnostic Support is a specific requirement for Access to RMI for heavy duty vehicles. It will be addressed separately in a future standard.
The standardized RMI terminology is contained in a ?Digital Annex' developed and maintained according to the complementary standard ISO 18542.

Standards 18541-1 to 4 are covering the field of light vehicles and 18541-5 will cover the field of heavy-duty motor vehicles.
The purpose is to treat specificities of mopeds and motorbikes, as well as all-terrain vehicles (quads) and other small vehicles with 3 or 4 wheels.

ISO 18541-6:2018 contains all elements (definitions, use cases, technical requirements, functional user interfaces requirements and conformance test cases) applicable for the standardized access to repair and maintenance information for two-wheeled and three-wheeled vehicles and quadricycles (L-category vehicles)
The development of this document has been based on ISO 18541‑1, ISO 18541‑2, ISO 18541‑3 and ISO 18541‑4. This document constitutes an adaptation of standardized access to RMI prescriptions for passenger cars to L-category vehicles keeping the objectives and principles of the mandate M/421 from the European commission.
ISO 18541-6:2018 references the usage of a Digital Annex of standardized search terms for RMI. The provision of such a Digital Annex will follow the process described in ISO 18542.
CEN will nominate a Registration Authority according to ISO 18542 for the creation and maintenance of an appropriate Digital Annex.

EN ISO 18542-2 is structured into two parts: - Part 1: General information and use case definition: defines a framework and a process for agreeing terms - Part 2: Standardized process implementation requirements, Registration Authority: defines the process implementation requirements for a Terminology Management System and for a Registration Authority with a Digital Annex. The purpose of the ISO 18542 series is to facilitate searching by Independent Operators (IOs) of Vehicle Manufacturer (VM) Repair and Maintenance Information (RMI) websites. This part of ISO 18542 specifies: - the technical requirements that must be met by the Terminology Management System (TMS) that will be used to manage and store the ‘Agreed RMI Terminology’; - the requirements for the Registration Authority (RA) (i.e. the agency responsible for maintaining and publishing the ‘Agreed RMI Terminology’). The framework and process for creating ‘Agreed Terminology’ is the subject of ISO 18542-1. The target audience for this part of ISO 18542-2 is a technical one, and focused on those responsible for the implementation of mandate M/421.

ISO 18542-2:2014 specifies:
- the technical requirements that must be met by the Terminology Management system (TMS) that will be used to manage and store the 'Agreed RMI Terminology';
- the requirements for the Registration Authority (RA) (i.e. the agency responsible for maintaining and publishing the 'Agreed RMI Terminology').

ISO 18542 is structured in two parts: - This part of ISO 18542 defines a framework and a process for agreeing terms. - Part 2 defines the process implementation requirements for a terminology management system and for a Registration Authority with a digital annex. The basic purpose of ISO 18542 is to facilitate searching of vehicle manufacturer (VM) repair and maintenance information (RMI) websites by independent operators (IOs). This part of ISO 18542 provides a general overview and structure of each part of ISO 18542. It also specifies use cases related to repair and maintenance information (RMI) terminology in order to standardize the access to RMI for IOs. The provision of the agreed automotive RMI terminology itself is outside the remit of ISO 18542 and therefore outside the scope of this part of ISO 18542. Rather, it is foreseen that the agreed automotive RMI terminology will follow a lifecycle beyond the timeframe of ISO 18542. It will be dependent upon the work of a Registration Authority, a Terminology Review Group for its creation and management, and of a digital annex for its publication. For the development of the digital annex, existing standards will be reviewed and elements included where appropriate and practical.
