19、ppointed by the Liaison Group CEN/TC 229-TC 250, particularly for its compatibility with structural Eurocodes. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2013, and conflicting nation
20、al standards shall be withdrawn at the latest by November 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document includes

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Tr
22、ade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. EN 15037, Precast concrete products Beam-and-block floor systems, consists of five parts: Part 1: Beams Part 2: Concre
23、te blocks Part 3: Clay blocks Part 4: Expanded polystyrene blocks Part 5: Lightweight blocks for simple formwork 1) For common aspects of concrete products, reference is made to EN 13369, from which also the relevant requirements of the EN 206-1 are taken. The references to EN 13369 by CEN/TC 229 pr
24、oduct 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. In all countries it may be accompanied by
25、alternatives for national application and it should not be treated as a European Standard. The program of standards for structural precast concrete products comprises the following European Standards, in some cases consisting of several parts: EN 1168, Precast concrete products Hollow core slabs 1)

31、lements which are supplied to the market and covers all the production operations carried out in the factory. For design rules reference is made to EN 1992-1-1. Additional complementary rules are provided where necessary. NOTE This European Standard is applied in Europe under different climatic and
32、geographical conditions, different levels of protection and under different, well-established, regional traditions and experience. Classes for EPS blocks have been introduced to cover these situations. Where such general solutions were not possible, the relevant clauses contain permission for the ap
33、plication of national standards or provisions valid in the place of use of the EPS Blocks (see 4.3.3). BS EN 15037-4:2010+A1:2013 EN 15037-4:2010+A1:2013 (E)1 Scope This European Standard deals with the requirements and the basic performance criteria for blocks made in expanded polystyrene (EPS), us
34、ed in conjunction with precast concrete beams in compliance with EN 15037-1, with or without cast-in-situ concrete for the construction of beam-and-block floor systems. EPS block may be totally made in EPS or combined with different materials such as plaster or wood wool. If EPS is combined with oth
35、er materials, these materials should not contribute to more than 50 % of the mechanical resistance of the block. If not, the block is covered by EN 15037-5, Precast concrete products Beam-and-block floor systems Part 5: Lightweight blocks for simple formwork. Examples of typology of floor systems ar

45、s 4.1 Material requirements The material EPS used shall comply the relevant requirements defined in EN 13163. If other materials are used in combination with EPS, there suitability shall be established. The establishment of suitability may result from a European Standard which refers specifically to
46、 the use of this material in building products; in absence of a European Standard it may also result, under the same conditions, from an ISO standard. Where this material is not covered by a European or International Standard, or if it deviates from the requirements of these standards, the establish
47、ment of suitability may result from: the relevant national standards or provisions valid in the place of use of the product which refer specifically to the use of this material in building products; or a European Technical Approval specifically for the use of this material in building products. 4.2
48、Production requirements Only the materials in accordance with 4.1 shall be used in the production of EPS blocks. 4.3 Finished product requirements 4.3.1 Geometrical properties NOTE For technical documentation, see Clause 8. 4.3.1.1 Production tolerances 4.3.1.1.1 Dimensional tolerances The dimension
