Road vehicles. Electrical disturbance by conduction and coupling. Part 3 : vehicles with nominal 12 V or 24 V supply voltage. Electrical transient transmission by capacitive and inductive coupling via lines other than supply lines.

Establishes a basis for the evaluation of the EMC of electronic instruments, devices and equipment in vehicles against transient transmission by capacitive and inductive coupling via lines other than the supply lines. Test is intended for the demonstration of the immunity of the above mentioned items against disturbances such as those caused by switching.

Le développement de l'électronique dans les véhicules routiers nécessite de s'assurer de la compatibilité électromagnétique des divers équipements électriques et électroniques entre eux. La présente norme fait partie d'un ensemble d'études destiné à évaluer d'une part les caractéristiques des transitoires émis par les sources de perturbations, et d'autre part leurs effets induits par conduction, par couplage ou par rayonnement. La méthode d'essai présentée utilise une pince de couplage et permet d'obtenir des résultats comparatifs entre laboratoires. Les niveaux d'essais proposés en annexe A sont déterminés par accord entre constructeurs de véhicules et fournisseurs d'équipements. Elle s'applique aux voitures particulières et véhicules utilitaires légers à tension nominale de 12 V ainsi qu'aux véhicules utilitaires à tension nominale de 24 V.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
