CE/FCC-certification | BICON Laboratories

CE/FCC-certification

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:

EMISSION

Conducted Emission
Radiated Emission
Harmonics emission
Flicker and voltage fluctuations

IMMUNITY

ElectroStatic Discharge
Radiated Immunity
Electrical Fast Transients
Surges
Conducted Immunity (CDN BCI/CCL)
Power Magnetic Field
Pulsed Magnetic Field
Short and Long DIPS-SAG testing
Voltage Fluctuations

ELECTRICAL SAFETY

Ground bonding
Insulation resistance
Hipot
Earth Leackage
Residual Voltage
Product safety assesment

 

Surges

Surges are high energetic disturbance signals which can reach voltages of several kilovolts. Every day, there are about eight million bolts of lightning out of 44.000 thunderstorms all over the world. That means about 100 discharges every second. Over-voltages of several Volts can damage components, but an interruption of a production process can even cause more (financial) damage. In addition to lightning transients, we know surges as a result of switching procedures in the public low voltage facilities.

With a special generator with a predefined source impedance, these surges are injected to the equipment under test (EUT). This is done with special coupling units to the power and interconnection lines. The pulse is displayed at the bottom of this page and can reach voltages up to 4 kilovolts. The selection of test voltage is done by means of defining 6 classes and an open class.

A test on system level is advised which simulates the real installation. The simulated installation comprises protective devices (arrestors, varistors, shielded lines, etc.) and the real length and type of the interconnection lines. This test is aimed at simulating as closely as possible the installation conditions in which the EUT is intended to function later on. In the case of the immunity under real installation conditions, higher voltage levels can be applied, but the energy involved will be limited by the protective devices according to their current-limiting characteristics.

The test is also intended to show that secondary effects produced by the protective devices (change of waveform, mode, amplitude of voltage or current) do not cause unacceptable effects on the EUT.

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:
  • (A) Normal performance within the specification limits;
  • (B) Temporary degradation or loss of function or performance which is self-recoverable;
  • (C) Temporary degradation or loss of function or performance which requires operator intervention or system reset;
  • (D) Temporary degradation or loss of function or performance which is not recoverable, due to damage of equipment (components) or software, or loss of data.
