GOST 28751-90 Electrical Equipment for Vehicles. Electromagnetic Compatibility. Electrical Disturbance by Conduction along Supply Lines. Requirements and Test Methods

This standard applies to newly designed electronic and electrical products (hereinafter referred to as products) intended for use in motor vehicles and establishes requirements for their electromagnetic compatibility for conductive interference in on-board networks with a nominal voltage of 12 and 24 V, as well as test methods.

General Provisions

Electromagnetic compatibility of products is characterized by noise immunity to conductive interference of the vehicle's on-board network, as well as the level of its own conductive interference measured at the power terminals.

The requirements for electromagnetic compatibility should be established in a differentiated manner in accordance with the requirements of this standard. The main factors in this should be the conditions of use, as well as the functions that the products must perform in the car. When these requirements are fulfilled, the products are considered compatible.

The conformity of the product to the requirements of this standard should be checked when the products are put into production, as well as when the design of the products or the manufacturing technology changes, if these changes can affect the requirements for their electromagnetic compatibility.
