? CE test consists of:?? EMC EMC testing and LVD Safety Test (accurate description of the product cost can call dwell) EMC = EMI + EMS EMI (electromagnetic interference) can be divided into:? 1 radiation (Radiation): Space radiation (Chamber) / power irradiation (Clamp) / open field test (Open site)? 2. conduction (Conduction)? 3. Power Harmonics (Harmonic)? 4. voltage flicker (Flicker)? EMS (electromagnetic tolerance) can divided into:????? 1.ESD (electrostatic withstand radiation testing) 2.EFT (pulse noise resistance test) 3.SURGE (anti-lightning surge test) 4.RS (resistant to RF radiation testing) 5.CS ( RF conduction resistance test)? 6.Magnetic Field (resistance to power frequency magnetic field test)? 7.DIP (resistant to voltage fluctuation test)? 8. The low-resistance conductive interference on ac power input? to 150KHz continuous conductive 9. dc resistance ? interference LVD Safety Test:? electric field / magnetic field radiation emission / immunity RF magnetic field radiation emission / conducted emission power harmonic RF / electrical fast pulse / surge conducted immunity Direct / induction ESD???? ??? input (power or current) normal temperature and humidity testing machine (tidal state) electric shock abnormal test:???? motor stall, blocking vents, abnormal temperature rise above the routine testing of EMC and LVD project engineer will be based on the actual situation and the needs of your product and make the appropriate test items. ? Do you want to provide certification: 1, two sets of samples to work properly, most powerful, most complex; 2, product brochures; 3, circuit diagram; 4, fill out the application form CE???.
