EM Test LD 200N Load Dump Generator for ISO 7637

The purpose of this standard defines the requirements to observe in order to ensure the electrical behavior and the Electromagnetic Compatibility (EMC) of the vehicles (specific vehicles and utility vehicles) and of associated electric, electronic and pyrotechnic equipment. The requirements defined in the standard constitute the reference for Supplier consultation. The PSA development head (in agreement with the PSA head of ECM and electric validations) should define for the Supplier the retained requirements. Without Supplier proposal and PSA written agreement, this document is applied integrally. Equipment is validated when it meets the test requirements on equipment or on vehicle. These tests on equipment should be carried out in an environment representing the operating mode on vehicle (system validation). Any project has an independent electric and ECM independent validation: A validation obtained on a vehicle project is not systematically renewable on another vehicle project. The general requirements relating to the electric and electronic equipment environment tests of the vehicles are listed in standard B21 7100.

ISO 16750 applies to electric and electronic systems and components for vehicles. ISO 16750-2 more specifically refers to road vehicles and their environmental conditions and electrical equipment testing.  ISO 16750 ISO 16750 focuses on the potential environmental consequences and highligh ts tests and requirements that are recommended for the specific mounting location on the vehicle. Several environmental factors were considered in the creation of the ISO 16750 series including world geography and climate, type of vehicle, vehicle use conditions and operating modes, equipment life cycle, vehicle supply voltage, and mounting location. Types of Testing for ISO 16750 Complience  Testing generator regulator failure Simulating jump start  Superimposing voltage Superimposing sinusoidal voltage Evaluating the effect of momentary drop in supply voltage Completeing frequency sweeping Verifing the DUT reset behaviour at different voltage drops Checking the resistance of the DUT Running other supply voltage tests ISO 16750-2 ISO 16750-2 is a subsection of the ISO 16750 standard in the general category of road vehicles for environmental conditions, electrical equipment testing, and electronic equipment testing. ISO 16750-2 describes the potential environmental stresses and specifies tests and requirements recommended for the specific mounting location on/in the road vehicle. Independent of the mounting location, electrical loads vary based on a vehicle wiring harness and connection system's electrical resistance. Direct current supply voltage Direct current supply voltage is something to consider when authenticating equipment functionality at the minimum and maximum supply voltage: Table 1 - Supply voltage for system devices with 12 V nominal voltage   Code Minimum supply voltage
