Edward, the requirement is that you comply with the essentials of the Directive, NOT with a standard.
If you comply with a harmonized standard, you are deemed to meet the essential requirements of the standard. The UK version of IEC 950 is just a British Standard that may or may not be harmonized. As long as one complies with the requirements of ANY version of IEC 950, published by CENELEC, one is deemed to comply with the Directive and justified in affixing the CE marking and drawing up a Declaration of Conformity. Ofcourse, the marking can be challenged on the grounds that the product constitutes a risk to life and limb. However, that can be done regardless of whether you meet any or all requirements of any or all standards. Meeting the requirements of a standard is no excuse for knowingly putting a dangerous product on the market. DOWN with all national versions of anything. Ciao, Vic
