2 Conformity evaluation test
In September 1995, the generic immunity standard (EN50082-2 *) was
harmonized by EU. Consequently, a manufacturer can declare, by themselves,
product conformity to the EMC Directive by indicating that the product meets
relevant harmonized standards.
* The generic immunity standard was replaced by EN61000-6-2 (April,
2002).
2.1 Items of conformity test for FANUC products
FANUC has been working with a German CB (Competent Body) before the
harmonized standards issued and we have prepared for declaration of
conformity by getting the CB’s certificate. FANUC products actually clear the
following tests.
No. Test Item / Standards / Level etc. Contents
1 Radiated emission
[EN55011]
Group 1, Class A
measure electromagnetic wave
emitted by products
2 Radiative susceptibility
[IEC61000-4-3 / EN61000-4-3] Level 3
[ENV50204] Level 3
apply electromagnetic wave to
products and check immunity
3 Conducted emission
[EN55011]
Group 1, Class A
measure electric noise emitted by
products to power line
4 Conductive susceptibility
[IEC61000-4-6 / EN61000-4-6]
Level 3
apply high frequency noise to power
and signal lines and check immunity
5 Electrostatic discharge
[IEC61000-4-2 / EN61000-4-2]
Contact: Level 2, Air discharge: Level 3
apply direct and indirect
electrostatic discharge on the control
panel or enclosure and check
immunity
6 Fast transient (burst)
[IEC61000-4-4 / EN61000-4-4]
Power line: Level 3, Signal line: Level 4
apply burst noise to power and signal
lines and check immunity
7 Surge
[IEC61000-4-5 / EN61000-4-5]
Power line: Level 4, Signal line: Level 3
apply lightning surge to power and
signal lines and check immunity
8 Voltage variation
[IEC61000-4-11 / EN61000-4-11]
±10% 5minutes
change input power voltage statically
9 Voltage dip

-30% 10ms,-60% 100ms,-60% 1000ms
change input power voltage
dynamically
10 Voltage interruption
[IEC61000-4-11 / EN61000-4-11]
-95% 5000ms
disconnect input power line
11 Power frequency Magnetic Field
[IEC61000-4-8 / EN61000-4-8]
Level 4 Continuous field
apply power frequency magnetic field
to products
MTBs still have an option to go through CB certification when they have a
problem of not being able to test their product because of size of products or
other reasons. Please consult with a CB.
