Does your DoC (Declaration of Conformity) need updating?
If you are a manufacturer or importer of IT type products you need to check your DoC is up to date.
From 1st October this year the 2006 + amendment 1 2007 version of EN 55022 (Emission standard for IT Products) will become the oldest available version of the standard still published in the EU Official Journal (OJ), which can be used for presumption of conformity to the EMC Directive.
To show presumption of conformity to the EMC Directive manufacturers will need to ensure their products meet the requirements of at least, this version of the standard.
The following standards cease to give a presumption of conformity from 1st October 2011:
EN 55022:1998,
EN 55022:1998 + A1:2000,
EN 55022:1998 + A2:2003,
EN 55022:1998 + A1:2000 + A2:2003.
This means that if you have had your equipment tested to any of the four standards mentioned above, you will need to update your existing Declaration of Conformity (if you are still placing your product on the EU market) and you may need to re-test your equipment.
The main difference between the superseded version and the 2007 version is that emission testing may now be up to 6GHz. The decision making process is as per the table below.
Highest frequency intentionally generated or used (MHz) by the product | Radiated Emissions Measurement will need to be performed up to.... |
<108 | 1000 MHz |
>108 - 500 | 2000 MHz |
>500 - 1000 | 5 GHz |
>1000 | 5 times the highest internally generated frequency or 6 GHz (whichever is less) |
Please note that EN 55022: 2010 is the latest listed version in the Official Journal, and should be used when updating your DoC to provide maximum product longevity.
