A new consolidated list of references of harmonised standards under the low voltage directive 2006/95/EC was published in the Official Journal C 61 of 29 February 2012.
More than 680 European standards provide solutions for compliance and presumption of conformity with relevant essential requirements of the low voltage directive. Although the references of these standards are published in the Official Journal of the European Union their publication is not required to provide for a presumption of conformity for low voltage products.
The use of harmonised standards is optional. Manufacturers can choose whether or not to follow a harmonised standard to manufacture their products. Manufacturers may thus go for any other technical solution but they must demonstrate that their products are in conformity with the mandatory safety requirements.
