One of the first questions when dealing with a regulation is to know what products are covered by it. The reply is slightly complicated but interesting: CPR covers construction products in two different ways; for some products the CPR requirements are compulsory and for others they are voluntary. We will explain both these cases in detail.
Applying CPR is compulsory for products included in the scope of a harmonised Product Specification (hEN). Manufacturers, according to the testing and calculations given in the text of the hEN, have to declare the performance of the products in the documents described in the CPR (including the CE marking and the Declaration of Performance). In particular, the declaration has to be made for the essential characteristics described in the Annex ZA of the hEN. Moreover, it is this Annex that is the tool to be used when developing the documents required by the CPR.
The standards developed by the Technical Committees of CEN become hEN when their titles are published in the Official Journal of the European Union (OJEU). The format in the OJEU is a table including the number of the hEN, the title and the dates for the co-existence period. Applying the regulation is compulsory from the end of the co-existence period and voluntary between the beginning and the end of it. The last update of the list published can be found through this link.
For the products not included in the scope of the hEN, the regulation offers an alternative through European Technical Assessments (ETA), known as Technical Approvals. In this case manufacturers can voluntarily request an assessment of the product from a Technical Assessment Body (TAB) to provide their clients with the information described in the CPR. Technical Assessment Bodies in this respect are (amongst others) the Approval Bodies known in the European Member States.
The documents containing the assessment methodology are called European Assessment Documents (EAD). TAB, using the EAD, assess the performance of the product and give the manufacturer a ETA which contains the results for the essential characteristics. Manufacturers use the information in the ETA to prepare the documents described in the CPR (including the CE marking and the Declaration of Performance).
The European Commission also publish the list of EADs in the OJEU when they are adopted by the association of TAB called EOTA. There is no co-existence period for EAD or ETA because they are issued under request from manufacturers for a specific product.
Products not included in the scope of a hEN and not assessed using a ETA cannot be CE marked according to the CPR. The most common products in this situation are innovative products for which the standards and assessment have not been developed but every year the list of products covered either in the compulsory or voluntary way grows.
