Beam-and-block floor systems, consists of five parts:  Part 1: Beams  Part 2: Concrete 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 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. In all countries it may be accompanied by 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 EN 12794, Precast concrete products — Foundation piles EN 12843, Precast concrete products — Masts and poles EN 13224, Precast concrete products — Ribbed floor elements

Sampling for initial type testing and for independent testing of consignments A.1 General This sampling procedure shall apply for initial type testing and in the event that there is a requirement for an assessment of product compliance. For independent testing representative of all parties shall have the opportunity to be present at the time of sampling. Only those properties declared by the manufacturer shall be assessed by this procedure. The required number of EPS blocks to determine compliance with specification shall be sampled from a consignment of up to 15 m3 or part thereof (see A.2.5). NOTE EPS blocks manufactured to this European Standard which have been the subject of third party inspection of their conformity control procedures are not normally subjected to independent testing of consignments after delivery. A.2 Sampling procedure A.2.1 General NOTE The choice of the method of sampling will normally be dictated by the physical form of the consignment in question. A.2.2 Random sampling Whenever possible, the random sampling method shall be used, in which every block in the consignment has an equal chance of being selected for the sample. The appropriate number of blocks shall be selected at random from positions throughout the consignment without any consideration being given to the condition or quality of those selected except that blocks damaged in transit shall not be selected. NOTE In practice, random sampling is normally only convenient either when the blocks forming the consignment are being moved in a loose (unpacked) form from one place to another or when they have been split into a large number of small stacks, e.g. on scaffolding awaiting laying. A.2.3 Representative sampling A.2.3.1 General When random sampling is impracticable or not convenient, e.g. when the blocks form a large stack or stacks with ready access to only a limited number, a representative sampling procedure shall be used. A.2.3.2 Sampling from a stack The consignment shall be divided into at least six real or imaginary sections, each of a similar size. An equal number of units shall be selected at random from within each section in order to give the required number of units without any consideration being given to the quality of those selected except that units damaged in transit shall not be selected.
