EN 55022: 2010 was superseded by EN 55032:2012 on 05/03/2017 and ceased to give presumption of conformity with the essential or other requirements of the relevant Union legislation. So why does EN 55022 no longer give presumption of conformity to the EMC Directive 2014/30/EU?
CE marking affects the supply of products to and allows free movement and sale of goods throughout the European Economic Area. CE-marking is mandatory within this region and as part of the mandated requirements it requires documentation in the form of a ‘Declaration of Conformity’ or commonly abbreviated to ‘DoC’ that states that the product meets all the applicable CE directives.
In this article we will discuss typical electrostatic discharge (ESD) problems and common solutions. Electrostatic discharge (ESD) is a common phenomenon that is encountered on an everyday basis by many of us. It is the sudden flow of electrical energy between two objects of differing electrical potential (or charge). ESD is essentially a lightening bolt on a very small scale and, like a lightening bolt, the electrical energy will try to find a low impedance path to ground in order to equalise the electrical potential. Anybody who has walked across a carpeted floor and touched a metal doorknob may have felt or even seen a small spark jump from their hand to the metal doorknob.
EMC compliance for HDMI Radiated Emissions testing (EMI) in Australia is a subject that many designers face with HDMI been incorporated into many consumer products. At EMC Bayswater we quite often see high speed data ports with cables that connect to various other products such as Ethernet Local Area Networks (LAN), HDMI etc. Many times these ports have been developed over years and have defined drivers with suitable filtering and so forth. HDMI poses a similar problem to the computer monitor video signal of the past apart from using faster data speeds and been much more complex.
Considering adding Bluetooth to your product? Not sure what Bluetooth EMC compliance is required. EMC compliance when adding Bluetooth to your host product may seem to some straight forward and to others a compliance nightmare. Hopefully this blog will help you get on track!
The Radio Equipment Directive (RED) Declaration of Conformity (DoC) key characteristics are listed in this article along with the required Technical Contents that should accompany the DOC and links to the relevant information sources. As an example we have used a imaginary product that has a Bluetooth module incorporated into a simple consumer product.
What is the Radio Equipment Directive (RED)? The European Union adopted a new set of rules regarding radio equipment that is put into service or placed on the European market. This change was confirmed back in 2014 to allow sufficient transition time at all levels. Each EU member state were required to adapt their National laws to accommodate the new Radio Equipment Directive (RED) (2014/53/EU, which was published on 22 May 2014). Radio Equipment Directive (RED) 2014/53/EU comes into full affect on 13 June 2016.
