CERTIFIED QUALITY
In addition to our strong commitment to total quality management, the development and production of our equipment meet the high requirements of various standards such as ISO9001, ISO14001, and ISO17025. These certifications guarantee compliance with rigorous quality procedures and documentation of every aspect of our business. Moreover, our systems meet a wide range of specifications and norms (EMI, CE, etc).
CB Scheme Testing: We test for worldwide compliance
All our products are tested by accredited labs according to harmonized standards and receive a CB scheme test report. The IECEE CB Scheme is an internationally recognized multi-lateral certification system for electrical and electronic products based on the IEC international standards. On request, we can also test against a broader range of specificationson the requirements of your unique application.
Our electromagnetic tests
Electromagnetic compatibility
At DEWETRON, ensuring electromagnetic compatibility (EMC) is essential for preventing electronic devices from interfering with each other, ensuring their reliable and safe operation. We rigorously test our products to withstand and minimize electromagnetic disturbances using specialized equipment and facilities. This ensures our products meet industry standards and perform reliably in various environments.
Radiated immunity
To make sure that our products are immune against radiated disturbances of electromagnetic fields, we test them in a special anechoic test chamber in a certified lab by using a generator and an antenna.
Reference: IEC/EN 61000-4-3
Power frequency magnetic field immunity
We also assure the functionality of our devices in strong magnetic fields. During the test, the device gets placed in a large coil with a generator producing a strong magnetic field.
Reference: IEC/EN 61000-4-8
Transient immunity, voltage dips, interruptions
Fast transients (bursts) and surges are electrical disturbances caused by switching events and lightning, respectively. We simulate these in our lab with a burst/surge generator. Short voltage drops and power interruptions, common in industrial settings, are also tested using a special setup with a waveform generator and power amplifier.
Reference: IEC/EN 61000-4-11, IEC/EN 61000-4-4, IEC/EN 61000-4-5
Conducted immunity
If a device is small compared to the wavelength, it won’t be greatly affected by interfering signals. However, connected cables can act as antennas and transmit these signals into the device. We use a coupling network to introduce such disturbances into the device’s connection lines to test its immunity.
Reference: IEC/EN 61000-4-6
ESD immunity
In dry environments, people and objects can build up an electric charge. When a charged object touches a device’s conductive part, it can cause a sudden electrical flow that damages circuits. We simulate this with our ESD (electrostatic discharge) gun.
Reference: IEC/EN 61000-4-2
Radiated emission
All electronic devices emit electromagnetic radiation that can affect other equipment. We measure and analyze this radiation using a spectrum analyzer and an antenna. These measurements are performed in a certified lab with a shielded, anechoic chamber to block external interference.
Reference: CISPR 16-2-3, MIL-461F, FCC 47 15B
Conducted emission, flicker, harmonic disturbances
Switching power supplies and non-linear components can cause disturbances in power or vehicle supply networks via cables. We detect and measure these disturbances using a line impedance stabilization network (LISN) and a spectrum analyzer to prevent them. Power-line flickers, caused by load current changes, are measured and limited to avoid distorting the supply voltage for sensitive lab equipment.

Our tests
Environmental & safety testing
At DEWETRON, ensuring environmental and safety compliance is essential for the reliability and durability of our products in various conditions. We conduct rigorous tests, including mechanical shocks, vibrations, and extreme temperatures, using specialized equipment. Additionally, we perform ingress protection (IP) and electrical safety testing according to international standards to meet industry regulations and ensure our products perform reliably in any environment.
Operating/storing temperature and humidity
Precision components perform best in controlled temperatures and low humidity. We’ve developed cooling mechanisms and use temperature-compensated components for a wide operating range. We validate these ranges using a climate chamber, ensuring our products function from Swedish ice lakes to Nevada deserts. We also simulate temperature and humidity effects during storage and transport.
Reference: 60068-2-1, 60068-2-2, 60068-2-14, 60068-2-30, 60068-2-78
Mechanical shock, vibration, seismic testing
DEWETRON products thrive in dynamic environments – on motorcycles, test rigs, wind turbines, or rocket launch sites. To ensure their robustness, we test all devices on electrodynamic shakers, simulating vibrations and impacts during operation and transport.
Reference: EN 60068-2-6, EN 60721-3-2, EN 60068-2-27
Ingress protection (IP)
It’s crucial to shield sensitive electronics from water, dust, and solid objects while also protecting users from internal hazardous voltages. IP codes define this protection level. We test for IP codes using test fingers, rods, dust, and water spray or shower chambers.
Reference: EN 60529
Electrical safety
All electrical devices must meet safety regulations in their target regions. We base our tests on the European Low Voltage Directive (LVD) and IEC/EN 61010 series standards. Besides internal testing, we collaborate with an independent accredited lab for additional safety testing.
Reference: EN 61010-1, EN 61010-2-30, EN-60950, EN 61558-1
Packaging tests
Each DEWETRON product receives custom packaging based on legal requirements, sample shipment data, and customer feedback. We prioritize reusable and eco-friendly materials like recycled paper and cardboard over bubble wrap and plastic.
