The numbering of clauses is strictly related to EN 13369, Common rules for precast concrete products, at least for the first three digits. When a clause of EN 13369 is not relevant or included in a more general reference of this standard, its number is omitted and this may result in a gap on numbering

Directive(89/106/EEC) of European Union (EU). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. This standard is one of a series of product standards for precast concrete products. For common aspects reference is made to EN 13369 : Common rules for precast products, from which also the relevant requirements of the EN 206-1 : Concrete - Part 1 : Specification, performances, production and conformity are taken. The references to EN 13369 by CEN/TC 229 product standards are intended to make them homogeneous and to avoid repetitions of similar requirements. Eurocodes are taken as a common reference for design aspects. The installation of some structural precast concrete products is dealt with by ENV 13670-1 : Execution of concrete structures – Part 1 : Common rules, which has at the moment the status of an European Prestandard. In all countries it can be accompanied by alternatives for national application and it shall not be treated as a European Standard. The programme of standards for structural precast concrete products comprises the following standards, in some cases consisting of several parts :  EN 1168, Precast concrete products - Hollow core slabs  prEN 12794, Precast concrete products - Foundation piles  EN 12843, Precast concrete products – Masts and poles  EN 13224, Precast concrete products - Ribbed floor elements  EN 13225, Precast concrete products – Linear structural elements  EN 13693, Precast concrete products – Special roof elements  prEN 13747, Precast concrete products – Floor plates for floor systems
 prEN 13978, Precast concrete products – Precast concrete garages  prEN 14843, Precast concrete products - Stairs
 prEN 14844, Precast concrete products – Box culverts SIST EN 12843:2004

 prEN 14992, Precast concrete products – Wall elements: Products properties and performances
 prEN 15037, Precast concrete products – Beams for beam-and-block floor systems This standard defines in Annex ZA the application methods of CE marking to products designed using the relevant EN Eurocodes (EN 1992-1-1 and EN 1992-1-2). Where, in default of applicability conditions of EN Eurocodes to the works of destination, design provisions other than EN Eurocodes are used for mechanical strength and/or fire resistance, the conditions to affix CE marking to the product are described in ZA.3.4. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
