Measurements
Conform the CE-legislation electrical equipment can be marked with a CE-label when complying with all relevant standards. When complying to all relevant standards the assumption of being in keeping with the EMC & LVD guidelines is met.
Of course there are many more kinds of measurements that can be performed by BICON laboratories (CE or Military). Please contact us here for more information.
Most measurements described in the relevant standards are explained in the following topics:
IMMUNITY
Voltage Fluctuations
| Voltage variations By connecting electrical and electronic equipment to low-voltage power supply networks, they are subject to voltage variations. Voltage variations are caused by the continuoulsy varying loads connected to the network. Voltage variations are not always abrupt, because of the reaction time of rotating machines and protection elements connected to the power supply network. If large mains networks are disconnected (local, within a plant or wide aea within a region) the voltage will only decrease gradually due to the many rotating machines, which are connected to the mains networks. For a short period, the rotating machines will operate as generators sending power into the network. Some equipment is more sensitive to gradual variations in voltage than to abrupt change. However, all electric and electronic equipment should work properly when these variations are within certain limitations (c.q. -15% / + 10%). By applying these voltages to the equipment, the immunity is determined. No malfunction or dangerous situation shall occur. When performing the tests it is required that the EUT and possible auxiliary equipment are exercising all normal modes of operation. The test results may be classified on the basis of the operating conditions and functional specifications of the EUT, according to the following performance criteria:
