EMC and Enviromental Simulation

Any defect in a product not recognized in time could end up being the cause of costs or in the worst case harm the reputation of the company. In order to counteract this danger, our products are tested in our test centers; from the development up to the qualification according to strict standards for their electromagnetic compatibility and environmental resistance.

By using the services of our laboratories, you too can benefit from our high-quality standards. We do not distinguish between our products and your products. Our demands are high – often beyond those of industry standards.

Accreditation - certified competence

The test center of HENSOLDT Optronics in Oberkochen is accredited to DIN EN ISO/IEC 17025.

The ILAC (International Laboratory Accreditation Cooperation) agreement gives our test results international recognition.

 

 

EMC - Electro Magnetic Compatibility

EMC is the characteristic of electrical and electronic equipment or systems to function satisfactorily in their electromagnetic environment, without inadmissible affecting their environment. The electromagnetic compatibility of devices is becoming increasingly important in a more complex environment.

In Europe and other parts of the world, compliance with emission and immunity limits is regulated by law. Without these regulations, interference-free operation of radio services and of electronic devices would no longer be conceivable today.

Testing Electromagnetic Compatibility

EMC Laboratory

The EMC laboratory in Oberkochen is a modern measurement and testing laboratory with a focus on components and systems of defense and automotive electronics. Due to our many years of experience, we are a competent and reliable partner for your needs.

At the Oberkochen site, HENSOLDT has a newly designed EMC laboratory. The heart of our facility are three similar semi anechoic absorber chambers, each designed for measurements and tests in accordance with MIL, VG, RTCA and Automotive standards.
