Full title and description

ISO 16505:2019/Amd 1:2021 — Road vehicles — Ergonomic and performance aspects of Camera Monitor Systems — Requirements and test procedures — Amendment 1 (adds definitions/requirements and test clarifications referenced as ORP, FeV and MTF10MIN(1:1)/hor, MTF10MIN(1:1)/ver).

Abstract

This document is Amendment 1 to ISO 16505:2019 and provides targeted additions and clarifications to the Camera Monitor Systems (CMS) requirements and test procedures. The amendment introduces or clarifies measurement parameters and limits for optical and image‑quality metrics (referenced as ORP, FeV and minimum MTF10 values in 1:1 aspect ratio horizontal and vertical measurements) intended to ensure adequate spatial resolution and ergonomics when CMS replace required rear‑view mirrors in road vehicles.

General information

• Status: Published (amendment to ISO 16505:2019).
• Publication date: July 2021 (Amendment 1 published July 2021).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 13.180 (Ergonomics); 43.040.10 (Electrical and electronic equipment).
• Edition / version: Amendment 1 to ISO 16505:2019 (applies to the second edition of ISO 16505).
• Number of pages: 2 (amendment document length).

Scope

The amendment applies to ISO 16505:2019, which sets minimum safety, ergonomic and performance requirements and associated test procedures for Camera Monitor Systems intended to replace mandatory inside and outside rear‑view mirrors on road vehicles (UN Regulation No. 46 classes I–IV). The base standard addresses system architecture, image quality, field of view, magnification, time behaviour and failure behaviour; the amendment refines specific optical and resolution measurement requirements.

Key topics and requirements

• Introduction/clarification of ORP and FeV parameters used in CMS measurement and verification (optical/ocular reference points and field‑equivalent values as applied to test setups).
• Minimum spatial‑frequency (MTF10) requirements specified as MTF10MIN(1:1)/hor and MTF10MIN(1:1)/ver to define acceptable horizontal and vertical resolution performance for the assumed 1:1 monitor aspect ratio.
• Test procedure notes and conversions for measuring MTF10 on rectangular displays; guidance to convert measurements to the 1:1 hypothetical monitor defined size used in CMS requirements.
• Clarifications intended to ensure driver ability to perceive required scene detail across representative distances (depth‑of‑field checks at typical test distances) and at corner measurement points of the displayed field.
• Alignment with ergonomic, safety and system‑availability aspects already in ISO 16505 (frame rate, flicker, distortion and magnification/aspect‑ratio constraints remain relevant).

Typical use and users

Automotive engineers (optics, imaging and HMI), vehicle manufacturers, Tier‑1 camera/display suppliers, verification and test houses, homologation authorities and standards committees use this amendment when specifying, testing or certifying Camera Monitor Systems that replace conventional mirrors. It is used alongside the main ISO 16505:2019 text to implement and verify image quality and ergonomic requirements in production CMS designs.

Related standards

ISO 16505:2019 (base standard) — the amendment applies directly to this document. ISO 16505 references regulatory documents for mirror classes (UN Regulation No. 46) and notes that safety‑relevant aspects of CMS should be considered together with functional safety standards such as ISO 26262. Other imaging and measurement standards commonly used alongside ISO 16505 include ISO 12233 (resolution/SFR/MTF measurement) and other ISO/IEC imaging test guidance for dynamic range, noise and distortion.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2021) to ISO 16505:2019, providing targeted additions and clarifications to requirements and test procedures for Camera Monitor Systems used to replace mandatory vehicle mirrors.

Q: What does it cover?

A: The amendment clarifies and adds specific measurement parameters (notably ORP, FeV and MTF10MIN metrics in a 1:1 aspect ratio context) and test‑procedure guidance for verifying spatial resolution and related image‑quality requirements alongside the broader ergonomic and functional requirements in ISO 16505:2019.

Q: Who typically uses it?

A: Vehicle OEMs, CMS camera and display suppliers, test laboratories, homologation authorities and engineers responsible for human‑machine interface, optics and system verification use this amendment in product specification and compliance testing.

Q: Is it current or superseded?

A: The amendment was published in July 2021 and is a published update to ISO 16505:2019. Users should check for any later revisions or new work items (ISO/AWI 16505 and other follow‑on activity have been noted in ISO’s lifecycle information) to ensure they are working with the latest consolidated requirements.

Q: Is it part of a series?

A: Yes — it is a formal amendment to ISO 16505:2019 (the second edition of the standard). ISO 16505 itself is part of ISO/TC 22/SC 35 work on lighting, visibility and visibility‑related ergonomics for road vehicles; related imaging and test standards are often used together with it.

Q: What are the key keywords?

A: Camera Monitor System (CMS), mirror replacement, MTF10, MTF10MIN(1:1), ORP, FeV, image quality, ergonomics, test procedures, UN Regulation No. 46, ISO 26262.
