Why do electronic products need to do EMC testing?

 There are the following considerations:

1. The electromagnetic spectrum is limited

The frequency band of each line has different functions. If each electronic product radiates disorderly electromagnetic waves, then thousands of electronic devices are launched, and the electronic devices of each frequency band will become extremely fragile (normal work will be disturbed at any time by other products).

This is also designed to protect the normal operation of various electronic devices.

2. Safety factors

For many products and industries, EMC's performance can mean life and death.

Many medical, military, industrial (such as power products, financial equipment), aerospace and automotive products (and other products) must be kept safe.

3. Economic factors

The electromagnetic interference of electronic equipment is undetectable and accidental. It is difficult to determine the cause and source of problems.

There are a lot of lawsuits caused by wireless transmitters, so controlling them from the source is also a strategy.

C-tick authentication concept A/c-tick is A certification mark for Communications equipment issued by the Australian Communications Authority (ACA).Manufacturers and importers must follow the next step in using A-Tick: : 1. Product implementation ACAQ technical standard test 2. Register the use of A/C-Tick to ACA 3. Fill in the Declaration of Conformity Form and keep the product with the record C - tick certification In communication products or equipment with A/C - the identity of the Tick marks (label) 5, sales to consumers A - Tick only applies to communication products, electronic products, mostly apply C - Tick, but electronic products if the application is A - Tick, do not need to apply for the C - other Tick.Since November 2001, EMI in Australia/New Zealand has applied for a merger;If the product is to be sold in the two countries, the following documents must be in place before marketing, in case the authorities of the Australian Communications Authority or the Ministry of Ec...

IC certification

图片
IC is short for Industry Canada, a government agency that is responsible for the certification of electronic products entering the Canadian market.Its products are generally divided into: broadcast television equipment, information technology equipment, radio equipment, telecommunications equipment, engineering medical equipment, etc. Like the FCC in the u.s., IC currently only restricts electromagnetic interference. IC authentication method: There are two ways of Certification and Certification. IC ID: CN (Company Number, up to 6 digits) +UPN (Unique Product Number, up to 8 bits). ID application: 1. The address information of the representative of Canada must be provided. 2. The label shall include the following information (manufacturer name or trademark, model name, IC ID number). Related standards of IC certification: IC certification standards are basically in line with the FCC, and IC currently only restricts electromagnetic interference. Y-001 analog equipment: Industrial, Sc...

NOM certification

图片
The Normas Oficiales Mexicanas logo is a mandatory safety sign in Mexico to indicate that the product is in accordance with the associated NOM standard.The NOM logo applies to most products, including telecommunications and information technology equipment, household electrical appliances, lamps and other products that are potentially dangerous to health and safety.All products manufactured or imported in Mexico must comply with the relevant NOM standards  and product labeling requirements. The product of NOM compulsory certification is generally a voltage over 24 volts alternating current or direct current electrical products.It is mainly applicable to product safety, energy and thermal effect, installation, health and agriculture.The following products must obtain a NOM DE certification to allow access to the Mexican market: -- electronic or electrical products for use by families, offices and factories; -- computer LAN (LAN) equipment; -- lighting fixtures; -- tires, toys an...
