EMC Compliance process and requirements to meet them.
UK legislation 2016 No.1091 is used to implement the European Directive for EMC,this means anything electronic/electrical that is liable to interfere or be interfered with requires to meet the requirements of the EU EMC Directive 2014/30/EU and the CE mark attaching to the product.
To ensure compliance with both 2016 No.1091 and 2014/30/EU, the manufacture will need to do some form of testing using harmonised standards listed in the OJ. Now when testing please bare in mind that compliance is presumed i.e you will never fully meet the requirements of the above.
2016 No.1091 Part 3 Section 39. (1) of 2016 No.1091 Presumption of conformity :
Equipment which is in conformity with a harmonised standard (or part of such a standard) the reference to which has been published in the Official Journal is to be presumed to be in conformity with the essential requirements covered by that standard (or that part of that standard).
2014/30/EU Presumption of conformity of equipment
Equipment which is in conformity with harmonised standards or parts thereof the references of which have been published in the Official Journal of the European Union shall be presumed to be in conformity with the essential requirements set out in Annex I covered by those standards or parts thereof.
Even though the word presumption is used you still have to prove some form of compliance to the above directive and this will involve some form of testing.
Once you have tested your equipment for EMC what’s next? Simple, from the offset of the project you should of made a technical construction file.This file will contain information such as :
- Technical description
- Drawings, circuit diagrams and photos
- Bill of materials
- Specification and, where applicable, EU declaration of conformity for the critical components and materials used
- Details of any design calculations
- Test reports and/or assessments
- EU declaration of conformity
- Technical documentation can be made available in any format (i.e. paper or electronic) and must be held for a period of up to 10 years after the manufacture of the last unit, and in most cases reside in the European Economic Area (EEA).
This technical file will then be stored and the CE mark applied to your equipment.
Does CE + CE = CE?
What do we mean with this? If you are a manufacture and you buy parts in to assemble your fully working product and you think you do not need to do EMC as all parts are CE marked, think again.Placing CE marked boards/parts together does not mean you will pass the harmonised standards and listed in the OJ. Its always better to perform some testing and build a technical construction file to prove you have gone some way to meeting the requirements of the directive.
Do I need to use a UKAS test house?
In most cases no you do not, you as a company can self certify by doing some form of testing and making a technical file for the product. Some cases that do need a UKAS test report is when you are applying for an E mark from the VCA (automotive testing Reg 10.05). If you need any advice or help on this then please feel free to contact us, we can advice and quote for work needed.

If you have never done one of these before we have placed a template below for you :
Once you have done the above page simply print onto company letter headed paper and store in the TCF.
