Classification of environmental conditions -- Part 3: Classification of groups of environmental parameters and their severities -- Section 5: Ground vehicle installations

Classifies the environmental conditions to which a product not forming part of the vehicle is subjected when installed in a ground vehicle. Such products are for example radios, communication systems, fare meters, and flow meters for liquids transported by the vehicle. Vehicles where products may be permanently or temporarily installed include road vehicles, rail vehicles, overland vehicles, handling and storage vehicles, and self-propelled machinery.

Classification des conditions d'environnement -- Partie 3: Classification des groupements des agents d'environnement et de leurs sévérités -- Section 5: Installations des véhicules terrestres

Classifie les conditions d'environnement auxquelles un produit qui ne fait pas partie du véhicule est soumis lorsqu'il est installé dans un véhicule terrestre. De tels produits sont les récepteurs radio, les systèmes de communication, les compteurs de kilométrage/tarification et les débitmètres pour les liquides transportés par le véhicule. Les véhicules sur lesquels des produits peuvent être installés de manière permanente ou provisoire comprennent les véhicules routiers, les véhicules ferroviaires. les véhicules tout-terrain, les véhicules de manutention et de stockage et les engins motorisés.

Overview

EN 60721-3-5:1997 (CLC) is the European classification standard that defines the environmental conditions and severity levels applicable to products installed in ground vehicles. Titled Classification of environmental conditions - Part 3: Classification of groups of environmental parameters and their severities - Section 5: Ground vehicle installations, the standard describes how to classify the external and in-service environments encountered by vehicle‑mounted equipment such as radios, communication systems, fare meters and flow meters.

Key topics

• Scope and purpose: Provides a structured system for assigning environmental condition groups and severity categories for products that are not part of the vehicle structure but are installed in or on ground vehicles.
• Environmental parameters: Addresses groups of environmental influences typically encountered in vehicle operation - for example temperature, humidity, vibration and shock, contamination (dust/liquids), and other transport/operational stresses - and defines severity levels for each group.
• Classification methodology: Describes how to select the appropriate environmental group and severity level based on vehicle type and installation conditions (road vehicles, rail vehicles, overland vehicles, handling/storage vehicles, self‑propelled machinery).
• Intended use: Helps manufacturers and test engineers determine the relevant environmental requirements and to plan environmental testing or design measures accordingly.

Applications

EN 60721-3-5 is practical for anyone who designs, specifies, tests or certifies equipment intended for vehicle installation:

• OEMs and integrators specifying in‑vehicle electronics (infotainment, telematics, fare collection).
• Product designers selecting components and protective measures to meet defined severity classes.
• Test laboratories mapping classification levels to environmental test programs.
• Fleet operators and purchasers defining procurement requirements for vehicle‑mounted systems. Using this classification ensures that vehicle‑installed equipment is specified and tested against realistic in‑service environmental profiles, reducing field failures and improving reliability.

Related standards

• Other parts of the EN 60721 series (other sections of Part 3 and Part 1/2) provide complementary classification and definitions.
• EN 60721-3-5 is typically used alongside environmental test standards and industry‑specific vehicle standards when developing test plans or compliance documentation.
