Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy whic ...
vehicle standard published by the
International Organization for Standardization (ISO), that relates to 12 and 24 volt electrical systems. As of November 2018, four parts of ISO 7637 have been published,
and one is in development (part 4):
* ISO 7637-1 (last revised
) Definitions and general considerations
* ISO 7637-2 (last revised
) Electrical transient conduction along supply lines only
* ISO 7637-3 (last revised
) Electrical transient transmission by capacitive and inductive coupling via lines other than supply lines
* ISO 7637-4 Electrical transient conduction along shielded high voltage supply lines only
* ISO 7637-5 (last revised
) Enhanced definitions and verification methods for harmonization of pulse generators according to ISO 7637
There are several distinct
electrical transient waveforms that are required from this testing to ISO 7637-2. These pulses or waveforms include very high rise or fall times often in the nanosecond and microseconds range. These transients are designed to simulate electrical occurrences in operational environments, including a
load dump In electronics, load dump means the disconnection of a powered load. It can cause 2 problems:
* failure of supply to equipment or customers
* large voltage spikes from the inductive generator(s)
In automotive electronics, it refers to the disconne ...
simulation. ISO 7637 is referenced by many vehicle manufacturer standards and individual waveforms are modified to meet specific requirements. ISO 7637 includes both immunity and emissions components of electromagnetic compatibility testing. This standard, including ISO 7637-2 places specific requirements on test equipment that can be used to replicate electrical occurrences.
