What is the meaning of presumption of conformity? 

A presumption of conformity means that you are deemed to meet the Essential Requirements of the CE marking Directives. You can benefit from a presumption of conformity by testing to European Harmonised Standards which are published in the Official Journal of the European Union. You can view a list of the 21 Directives and their associated Official Entry listings from the website of the European Commission: http://ec.europa.eu/enterprise/policies/european-standards/documents/harmonised-standards-legislation/list-references/index_en.htm

You do not have to test to European Harmonised standards but then you lose the benefit of the presumption of conformity and have to explain your compliance rationale in the technical file.

Why are fixed installations not ‘policed’ form of EMC point of view?

Fixed installations as defined in directive 2004/108/EC do have EMC guidelines for establishing compliance with the relevant essential requirements. The requirements are vague but never the less are included. Compliance is normally demonstrated by the use of a technical construction file incorporating evidence of good engineering practices during installation and ongoing maintenance, COTS equipment compliance, in-situ testing of both system components and whole installation boundary tests along with technical rationale for untested components or assemblies.

I have read that any product can have a CE marking if we/I feel that the product complies with all the relevant UK/EU Regulations/Laws, Is this correct that we can label anything for sale within EU?

You can only apply CE marking where there is a relevant CE marking Directive and where you can demonstrate compliance. If there is no relevant CE marking Directive then you must not apply CE marking.

Can you use other country requirements (e.g. FCC emissions) to cover part of EMC directive?

You can use other rationales to demonstrate compliance but you need to explain the rationale. Be aware that by not testing in accordance with EN standards you will not benefit from a presumption of conformity with the Essential Requirements of the Directive. In this specific case also be aware that the mains supply voltage / frequency may be different for FCC.

Please could you highlight the differences between the residential and industrial EMC testing requirements? I also understand that there is a third category which is for use in EMC controlled environment. We are most interested in the requirements for apparatus for use in industrial applications.

Emissions requirements for an industrial application are less severe than those stated for commercial areas. Immunity requirements however are more stringent as equipment will need to be tested to higher levels i.e. Radiated immunity levels are 10V/m for industrial applications and 3V/m for the commercial environment. Generic Standards for 'Residential, Commercial and Light-industrial' are as follows: EN 61000-6-1 = Immunity; EN 61000-6-3 = Emissions. Generic Standards for 'Industrial' environments are as follows: EN 61000-6-2 = Immunity; EN 61000-6-4 = Emissions. For more information regarding the classification of electromagnetic environments please refer to IEC 1000-2-5.

The equipment I supply is placed in a factory and is not relocated once installed.

Is my equipment therefore classed as a Fixed Installation?

Fixed installations cannot be supplied. Only apparatus can be supplied as this takes into account systems too. The apparatus will be installed into a fixed installation. Your equipment will therefore need to meet the requirements for apparatus but information such as installation and maintenance guidance will also need to be supplied. Your EMC Technical Documentation will then be held by the Fixed Installations Responsible Person and contained within the site specific EMC Technical File.
