Each 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, governm
20、ental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenanc
21、e are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention
22、is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

26、cles (e.g. classes I to IV as defined in UN REGULATION NO. 46). This International Standard can follow updates of referred national regulations that influence the included contents.Where possible, the requirements established for a CMS providing a specific legally prescribed field of view are based
27、on the properties of conventional state of the art mirror systems providing that field of view.The CMS is treated as a functional system in regards to requirement definitions and performance tests.This International Standard outlines general requirements and test methods regarding the basic aspects
28、of CMS; e.g. intended use, operating readiness, field of view, magnification, etc.Furthermore, this International Standard outlines requirements and test methods regarding the necessary object size and resolution provided by the CMS. Besides the properties of the mirror system to be replaced, those
29、requirements are also based on physical aspects of the human operator (e.g. visual acuity).The given requirements follow the assumption, that the CMS provides an ideal mapping of the real world scene. To correspond to reality, this International Standard also provides requirements and test methods f
30、or all relevant parameters that worsen the ideal mapping (e.g. isotropy or artefacts).Finally, this International Standard gives requirements and test methods regarding the aspects of time behaviour and failure behaviour.All requirements are established to be as generic as possible, i.e. that these
31、are possible to apply to any of the covered rearview mirrors. If additional or specific information is required for certain mirrors, these are provided in separate annexes.This International Standard declares that CMS replacing legally prescribed mirrors have to be considered as safety-relevant syst
32、ems and therefore, relevant safety standards (e.g. ISO 26262) have to be considered.vi ISO 2015 All rights reservedBS ISO 16505:2015Road vehicles Ergonomic and performance aspects of Camera Monitor Systems Requirements and test procedures1 ScopeThis International Standard gives minimum safety, ergon
33、omic, and performance requirements for Camera Monitor Systems to replace mandatory inside and outside rearview mirrors for road vehicles (e.g. classes I to IV as defined in UN REGULATION NO. 46). It addresses Camera Monitor Systems (CMS) that will be used in road vehicles to present the required out
34、side information of a specific field of view inside the vehicle. These specifications are intended to be independent of different camera and display technologies unless otherwise stated explicitly. ADAS Systems (such as parking aid) are not part of this International Standard.NOTE 1 Mirror classes V
35、 and VI (as defined in UN REGULATION NO. 46) are not in scope of this International Standard since the requirements are already defined in UN REGULATION NO. 46.NOTE 2 The definitions and requirements in this International Standard are formulated with regard to a system structure, where one camera ca
36、ptures one legally prescribed field of view and one monitor displays one legally prescribed field of view. Of course, also other system structures (e. g. with one monitor displaying two legally prescribed fields of view) are within the scope of this International Standard. For those systems, either
37、the system supplier or the vehicle manufacturer has to prove that the resulting system fulfils the requirements given in Clause 6.NOTE 3 Whenever the phrases “field of view” or “field of vision” are used, then both have the same meaning and are to be used in parallel.2 Normative referencesThe follow
