Description (English):

This document applies to electric and electronic systems and components for vehicles including electric propulsion systems and components with maximum working voltages according to voltage class B. It describes the potential environmental stresses and specifies tests and requirements for the specific mounting location on/in the vehicle. This document contains the terminology for the ISO 16750 series and general requirements. This document is not intended to apply to environmental requirements or testing for systems and components of motorcycles and mopeds. Electromagnetic compatibility (EMC) is not covered by this document. Systems and their components released for production, or systems and their components already under development prior to the publication date of this document, can be exempted from fulfilling the changes in this edition compared to the previous one.

Abstract

Overview

ISO 16750-1:2023 - "Road vehicles - Environmental conditions and testing for electrical and electronic equipment - Part 1: General" defines the general framework for environmental requirements, terminology and test planning for automotive electrical and electronic (E/E) systems and components. It applies to systems including electric propulsion components with voltage class B and outlines how environmental stresses are classified by mounting location, operating mode and functional status. Note: electromagnetic compatibility (EMC) is not covered and the standard excludes motorcycles and mopeds. Systems already released or under development prior to publication may be partially exempted from some changes.

Key topics and technical requirements

Terminology and coding system: Standardizes terms across the ISO 16750 series and provides a coding scheme to define complete environmental requirement sets.
Classification by mounting location: Distinguishes compartments (engine/electric motor, passenger, luggage/load, exterior/cavities and others) so tests match expected real-world exposure.
Operating modes: Defines operating modes (including additions for 48 V and voltage class B DUTs) to reflect realistic vehicle power states during tests.
Functional status classification: Specifies functional classes (A–E) for condition assessment during/after tests.
Tests and requirements: Establishes general test conditions, sequences, setups, procedures, parameter checks and visual/physical analysis requirements for environmental testing.
Mass and volume considerations: Recognizes component mass/volume impacts on vibration and thermal response and includes a sample mass classification (Annex C) to adjust test profiles.
Test planning tools: Includes informative annexes with example test plans, life-test/reliability statements and component mass classification.

Practical applications

ISO 16750-1:2023 is used to:

Develop robust test plans for automotive E/E components and systems.
Define environmental requirement sets based on mounting location and expected usage.
Guide design validation, reliability and life-cycle testing for sensors, ECUs, inverters, motors and other E/E equipment.
Support suppliers and OEMs in specifying and verifying environmental resistance to temperature, vibration, shock, humidity, dust, pollution and altitude.

Who should use this standard

Automotive OEM design and validation engineers
Tier‑1 and Tier‑2 suppliers of E/E components (including electric propulsion components)
Automotive test laboratories and quality engineers
Product managers and compliance teams planning environmental testing and documentation

Related standards

ISO 16750 series (other parts covering specific test types and levels)
For electrical testing of voltage class B and 48 V circuits, see ISO 21498 and ISO 21780 (as referenced in the introduction)

ISO 16750-1:2023 is essential for anyone specifying or testing road-vehicle electrical/electronic equipment against internationally harmonized environmental conditions.
