Some construction products are not covered by harmonised standards under the Construction Products Regulation. Construction products not covered by an hEN or an ETA may not be CE marked. For such products the manufacturer may either apply for a voluntary ETA that will allow the use of a CE mark on the product, or may choose to market and sell the product without a CE mark.
National rules on marketing and sale may apply to construction products that are not covered by harmonised rules, for example building components that come into contact with drinking water.
For further information about building components in contact with drinking water, go to the following website.
