UN Test Center
For transportation purposes a test certificate is mandatory according to UN 38.3. All necessary tests and experimental series can be carried out by our own UN test center. The following tests and simulations are required:
Low pressure existing during air transportation is simulated in a vacuum oven. Pressure is reduced to 115mbar over 6 hours which corresponds to about one-ninth of normal pressure.
Battery packs are exposed to temperatures of -40°C until +75°C in a climate cabinet for several days.
Vibration and shock test
A vibration generator also referred to as shaker generates different vibrations and shocks which are normal for transports.
Short circuit and overcharge test
By means of special testing devices, short circuits and overcharge of battery packs are simulated. Subsequently, all battery packs being in examination are controlled over one week.
RoHS - Restriction of Hazardous Substances
According to EU guideline, electric and electronic devices and components aren´t allowed to contain poisonous and non-biodegradable substances (e.g. heavy metal). ANSMANN implements this guideline consequently.
The composition of included materials is analyzed by X-ray spectrometers. Thus, hazardous substances can be easily identified and if necessary eliminated.
EMC test (electromagnetic compatibility)
Electromagnetic Compatibility is defined as the ability of electric and electronic devices to run under electromagnetic external radiation without causing disturbances for other gadgets.
By means of special testing and measuring methods our staff ensures that all devices meet all required guidelines and laws.
During this In-Circuit-Test, battery packs and the corresponding protection circuit are checked for errors in conductor path (such as short circuits and interruptions), for soldering defects and component failures.
