EMC Confirmation Inspection Report
Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any equipment in its environment.
More Introduction
1. Electromagnetic Compatibility (EMC)
Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit; degree of immunity, ie electromagnetic susceptibility.
EMC includes two parts: EMI (electromagnetic interference) and EMS (electromagnetic tolerance). The so-called EMI electromagnetic interference is the electromagnetic noise generated by the machine itself in the process of performing its due functions that is not conducive to other systems; and EMS refers to the machine. The ability to perform its intended function independently of the surrounding electromagnetic environment.
2. Electromagnetic Compatibility EMC Inspection Items
1. Electromagnetic emission (EMI) inspection items:
Conduction (CE) (150kHz～30MHz)
Magnetic field radiation (9KHz-30MHz)
Intermittent interference voltage (150kHz, 500kHz, 1.4MHz and 30MHz)
Power radiation (30MHz～300MHz)
Space radiation (30MHz-1GHz)
Harmonic current and voltage fluctuation and flicker (2-40th harmonic)
2. The inspection items of electromagnetic immunity (EMS) are:
Electrostatic discharge immunity
Radiated electromagnetic field (80MHz～1000MHz) immunity
Electrical fast transient/burst immunity
Surge (lightning strike) immunity
Immunity of injected current (150kHz～230MHz)
Voltage dips and short interruptions immunity
Power frequency magnetic field

5. the implementation of electromagnetic compatibility EMC confirmation test
Confirmation inspection items are generally carried out in accordance with the inspection items specified in the national standards, industry standards or the supplier's enterprise standards for the key components and raw materials; when the factory or the supplier itself does not have the capability for relevant inspection items, regular confirmation inspections can be carried out. Entrust a laboratory organization with relevant qualifications to carry out.
6. Organizations that handle EMC confirmation inspection reports
ANCI is a global certification and testing service provider focusing on IT, AV, power supply, wireless and communication products. It has obtained the accreditation of China National Accreditation Service for Conformity Assessment (CNAS L6214) and the qualification of inspection and testing agency CMA (201819013768) Qualification, 2 The EMC laboratory operates continuously and efficiently throughout the day. The one-to-one service of senior EMC engineers can help your products quickly obtain EMC confirmation inspection reports and sell them in the Chinese market.
