ISO 7637 is an automotive EMC test standard that outlines testing requirements for simulating electrical transients in road vehicles with 12V or 24 V electrical systems. ATEC carries EMC test equipment designed to meet the test specifications of ISO 7637-2, the latest version of the standard. Read on for more information about ISO 7637, applicable test pulses, and recommended ISO 7637 test equipment. What is ISO 7637? ISO 7637 defines test parameters for the EMC testing of road vehicles, specifically the simulation of electrical disturbances, or transients, in vehicle power supply lines. The standard, which covers both susceptibility and emissions testing, defines proper waveforms for test pulses and lists necessary electrical components. ISO 7637 also offers performance classifications for test pulses based on their frequency, strength, and burst cycle; ratings vary between pulses, and for the 12V or 24V electrical systems of commercial vehicles. Automotive manufacturers across the world rely on ISO 7637 to ensure the electromagnetic compatibility of their electrical systems; it is a common requirement for vehicle component development. Discovering a vulnerability to transients early on in automotive design is essential, as failures during formal EMC testing waste companies’ time and money. ISO 7637 is designed to protect car electronics that are vulnerable to surges from automotive power supplies. Since the advent of EMC testing, manufacturers have developed their own EMC standards in response to the myriad of electrical disturbances to which road vehicles fall victim. ISO, the International Organization for Standardization, developed ISO 7637 as a universal standard that covers as many varieties of automotive transients as possible.   ISO 7637 Subsections ISO 7637 is composed of five parts: ISO 7637-1 Definitions and general considerations ISO 7637-2 Electrical transient conduction along supply lines
