EMC testing of wiring harness
Electromagnetic compatibility testing is an essential step to ensure the quality of wire harness products.
This type of testing helps to identify potential sources of interference that may disrupt the performance of electronic equipment.
It also ensures the safety of personnel who are using or working with the product by detecting any harmful levels of radiation that could be emitted from it.
The test works by exposing a wire harness product to a variety of different types of electromagnetic fields and measuring the amount of induced current in the metal wires and components.
The test can also measure how well a product is shielded from electromagnetic interference, as well as its susceptibility to external interference.
There are several different methods used for performing electromagnetic compatibility tests on wire harness products, such as conducted emission testing, radiated emission testing, immunity testing, and precompliance testing.
Conducted emission tests involve exposing a sample to an externally generated signal, while radiated emission tests involve exposing it to an internally generated signal. Immunity tests involve subjecting a sample to various types of disturbances such as static voltages or magnetic fields. Precompliance testing is used to ensure that a product conforms with applicable standards prior to actual certification testing.
In addition to these standard types of tests, there are other specialized tests available for certain applications such as automotive or aerospace applications which require extreme levels of immunity and shielding protection due to their unique environments or conditions.
For example, automotive wiring harnesses must be tested for resistance against extreme temperatures, vibration, dust and water ingress in order to meet OEM requirements for vehicle safety and reliability.
It is important for manufacturers and suppliers alike to understand that proper electromagnetic compatibility tests are essential in order to ensure the safety and reliability of wire harness products before they reach the market.
In many cases it can save time and money by eliminating costly recalls due to poor quality control processes during production.
By utilizing advanced test techniques and having access to appropriate resources manufacturers can gain greater insight into their product's performance characteristics prior to release, thus saving them time and money in the long run while helping them achieve higher levels of customer satisfaction.
