Update on EN 55014-1:2017 Amendment A11:2020

EN 55014-1:2017(CE type approval)is the principal standard for electromagnetic disturbance requirements. It specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools, and more apparatuses whether powered by AC or DC.

The standard of CE type approval applies to conducted and radiated radio-frequency disturbances from appliances whose main functions are performed by motors and switching or regulating devices unless the RF energy is intentionally generated or intended for illumination.

This includes equipment such as household electrical appliances, Electric tools Regulating controls using semiconductor devices, Motor-driven electro-medical apparatuses. Amendment A11:2020-As technology advances, household products have also grown more complex. This has increased the probability of electromagnetic interference for these products. Amendment A11:2020 was created largely to address this EM disturbance.

Amendment A11:2020 makes significant changes to EN 55014-1, including:

1. Definitions – All specific operating conditions have been moved to Annex A.

2. Operating Conditions – The Amendment also includes specific operating conditions for many new products, including robotic operated machines, cooking equipment, and more.

3. Technical Requirements – The standard introduces fundamental technical changes relating to communications ports, including both wired network ports and radio interfaces.

4. These requirements were taken from CISPR 32 which has included emission requirements for wired network ports for many years.

5. The Amendment also clarifies that the standard covers ‘radio-enabled’ products within its scope, but limits the requirements to disturbance measurements of the non-radio emissions.

More changes:

1. Radiated emissions – the addition of general and specific test setups.

2. Test methods – provision for the current probe test method for conducted disturbance measurements on ports other than the AC mains port.

3. Explanations about click analysis -measurements under the presence of continuous disturbances.

4. More information about the use of the artificial hand.

5. Clarification about the measurement of equipment with built-in luminaries.

What does the Amendment mean for manufacturers?

if your products covered by EN 55014-1, these changes may have an impact on your product’s compliance. Please note that the changes included in the Amendment are significant. Your product may require additional testing to ensure compliance with the new tests. Any corresponding technical documentation and declarations will also need to be updated if test results show conformity to legislation, such as the EMC Directive for CE marking.
