Introduction to EN 300 220 Standard

EN 300 220is a European standard that mainly addresses electromagnetic compatibility (EMC). This standard specifies the requirements for equipment to operate correctly in an electromagnetic environment, including immunity to interference and emission limits. It applies to specific types of electronic equipment to ensure that they do not cause interference to other devices during use while being able to resist external electromagnetic disturbances.

Structure of EN 300 220

EN 300 220consists of two parts:

EN 300 220-1

Specifies the technical characteristics and test methods regarding electromagnetic compatibility and radio spectrum matters (ERM) for short-range devices (SRD) operating in the 25 MHz to 1000 MHz frequency band with a maximum power of 500 mW.

EN 300 220-2

A harmonized standard covering the essential requirements of Article 3.2 of the R\&TTE Directive.

Latest Versions

The current versions of the standard are:

1. EN 300 220-1 V2.3.1 (2010-02)

2. EN 300 220-2 V2.3.1 (2010-02)

DOP (Date of Publication of harmonized standard):November 30, 2010

DOW (Date of Withdrawal of previous version):May 31, 2013

After May 31, 2013, the following older versions became obsolete:

1. EN 300 220-1 V2.1.1 (2006-04)

2. EN 300 220-2 V2.1.2 (2007-06)

Scope of EN 300 220

EN 300 220 covers a wide range of products. It applies to all SRD equipment operating in the 25 MHz to 1000 MHz frequency band, with any type of modulation, antenna, and with or without speech. This includes:

1. Alarm systems

2. Radio frequency identification (RFID) devices

3. Radio remote controls

4. Measurement devices

5. Radio detection equipment

6. Movement detection devices

Key Differences Between New and Old Versions

1. Added requirements for Category 3 receiver blocking tests.

2. Redefined the method for classifying narrowbandand widebandsignals. The new standard defines equipment with channel bandwidth or spacing ≤ 25 kHz as narrowband, whereas the old standard defined narrowband as ≤ 200 kHz. This change affects tests for frequency error, adjacent channel power, and modulation bandwidth.

3. Updated the transient powertest procedures and limits.

4. Updated the modulation bandwidthtest procedures and limits.

These updates directly affect all radio devices within the scope of EN 300 220-1/-2, such as 27 MHz and 40 MHz wireless remote control toys, 433 MHz wireless doorbells, and 866 MHz wireless switches.
