EMC and environmental simulationAny 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.
The EMC laboratory in Oberkochen is a modern measurement and testing laboratory with a focus on cmponents and systems of defence 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 designes EMC laboratory. The heart of our facility are three similar semo anechoic absorber chambers, each designed for measurements and tests in accordance with MIL, VG, RTCA and automotive standards.

Resistance to environmental influences
Environmental influences are ubiquitous and can negatively impact the performance, reliability and durability of a technical product. The main objective of testing is to prove product reliability under the influence of extreme environmental conditions.
In addition, environmental changes in the behaviour of the test specimens can be determined within a short period of time, enabling targeted optimisation of the products.
In the environmental laboratory of HNSOLDT Optronics, we carry out environmental testing in accordance with all common test standards in the fields of mechanical egineering, automotive engineering, rail transport, aerospce, telecommunications, medical technology and many other areas for you.
To ensure that your profuct has the required performance both after storage and transport as well as during operation, we test the reliability of your products under extreme environmental conditions. In this way, we can determine changes in the behaviour of the test specimen in response to mechanical and climatic stress within a short time, thus enabling targeted optimization of the product.
