Standard Update: EN 55014-1:2021 and EN 55014-2: 2021

EN 55014-1:2021 and EN 55014-2:2021 provide the electromagnetic compatibility (EMC) requirements 为 household appliances and similar, including those employing 连接技术.

什么是55014- 1:21 21?

This is the product standard 为 electromagnetic disturbance (EMC emissions) requirements 为 household appliances, 电动工具, 以及类似的设备.

It specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from household appliances, 电动工具, 以及类似的设备, whether powered by AC or DC (including a battery).

什么是55014- 2:21 21? 

It indicates the electromagnetic immunity requirements in the frequency range of 0 Hz to 400 GHz that apply to the same household appliances, 电动工具, 以及类似的设备.

Common domestic appliances like washing machines, 滚筒式烘干机, and refrigerators all fall under the scope of EN 55014, as do electric/electronic toys, automatic dispensing machines, 个人护理, 以及美容用品.

Extension of the frequency range 为 radiated emissions and immunity

A key update and significant technical change to the previous editions include the extension of the frequency range 为 radiated emissions up to 6 GHz in EN55014-1 and EN 55014-2, the extension of the frequency range 为 radiated immunity up to 6 GHz.

“As household appliances become increasingly ‘smart’ in terms of their wireless capability and interconnection to the IOT, the need 为 comprehensive EMC 测试 has become increasingly critical.”

Additional 测试 may be required

This extension of the frequency ranges 为 both radiated emissions and immunity now brings EN 55014 into alignment with other 特定于产品的标准. 为制造商, it means if they have a product that includes a clock frequency greater than 108 MHz, they will need to consider the additional radiated emissions 测试.

同样的, from an immunity perspective, if they have a mains-powered product that includes a clock frequency greater than 200 MHz, they will need to consider the new equipment category 5 requirements resulting in additional radiated immunity 测试.

The addition of requirements 为 wired network ports also means affected products will require additional tests.

其他技术变更

其他技术变化, the details of which are outlined in part one 为 emissions or part two 为 immunity of this product family standard, 包括:

• an advanced categorization of equipment
• revision of general test conditions and the addition of new specific test conditions. For example, 为 robotic equipment and IPT other than induction cooking appliances
• clarification of requirements applicable to equipment incorporating radio functions
• revision of definitions and addition of new ones
• deletion of requirements referring to statistical evaluation. This in为mation is now contained within in为mative Annex D 为 EN 55014-1: 2021.

你准备好了吗??

Manufacturers of any of the products covered by EN 55014-1 and EN 55014-2 need to check if any of the changes might have an impact on the compliance of their product against the standard.

Additional 测试 may now be required to ensure that a product is compliant with the standards be为e its transition period comes to an end in October 2023.

If the test results are required to demonstrate con为mity to legislation, such as the 电磁兼容指令 为 CE标志, then any corresponding technical documentation and declarations will need to be updated accordingly.
