30、titions suitable for the use for which they are intended. 4.2 Materials gypsum blocks according to EN 12859; gypsum-based adhesives for gypsum blocks according to EN 12860; other materials and accessories can be used. 4.3 Structure and Functions 4.3.1 General The following factors can influence the

31、choice of the type of gypsum blocks and shall be taken into account with the structural requirements: a) type of building (single-family houses, buildings, etc.), purpose (accommodation, schools, offices, hospitals, etc.) and use (for example: damp rooms); EN 15318:2007 (E) 7 b) dimensional accuracy

32、 of the structure; c) service arrangements (distribution of fluids, electricity); d) type of connections to the structure and to the incorporated elements (frames, etc.), fixing loads. The following functions shall also be taken into account in the choice of the type of gypsum blocks: e) exposure to

33、 impacts and abrasion; f) temperature and humidity conditions; g) thermal insulation; h) sound insulation; i) safety in the event of fire. 4.3.2 Dividing or separating partitions The partitions ensure one or more of the following functions: Separation, fire protection, sound insulation or thermal in

34、sulation, supporting of loads, impact strength. 4.3.3 Backing partitions Backings are structures intended to reinforce the thermal insulation, sound insulation or fire resistance properties of the structures against which they are backed. 4.3.4 Ducts The ducts ensure one or more of the following fun

35、ctions: protecting the ambient medium against noise generated or transmitted by the shafts; protecting the shafts against fire; preventing propagation of the fire from one room to another. Vertical ducts can be made of gypsum blocks on one or more faces according to their positioning relative to the

36、 shell construction. The duct walls can be single or composite according to the performance required. 4.3.5 Lining of posts For aesthetic or technical reasons (fire resistance), all types of post (wood, metal, concrete ) can be protected by gypsum block structures. 4.4 Specific structural requiremen

37、ts 4.4.1 General Depending on the type of building or purposes of the rooms, special precautions shall be taken into account. 4.4.2 Damp rooms In rooms exposed intermittently to water, either by use or by the need to wash the surface of the partition or the adjacent floor, water-repellent gypsum blo

38、cks shall be used. EN 15318:2007 (E) 8 The type of blocks is determined depending on the planned use of the room and on the level of exposure of the wall to water. 4.4.3 Walls exposed to impacts In rooms where a higher surface resistance is required with respect to impacts (e.g. schools, corridors )

39、, it is recommended to use high-density blocks in the areas involved. 4.4.4 Safety in the event of fire Where the structure is considered to meet fire resistance requirements, it shall have been the subject of a test and a classification according to EN 13501-2. The blocks can also be selected as a

40、function of the fire resistance values in use specified in 4.5.2.2, Table 1. 4.4.5 Protection against noise Where the structure is considered to meet sound insulation requirements, the blocks are selected as a function of the information in 4.5.5. 4.4.6 Overhanging partitions Special provisions shal

41、l be made to improve the safety conditions in use. 4.5 Requirements 4.5.1 Mechanical strength and stability Gypsum block partitions are self-supporting non-loadbearing structures that do not affect the general stability of the structure. The mechanical requirements linked to safety in use are covere

42、d in 4.5.3. 4.5.2 Fire behaviour 4.5.2.1 Reaction to fire Gypsum blocks conforming to EN 12859 are classed as Euroclass A1 (non-combustible) without testing when they contain less than 1% by volume or by mass (according to the most unfavourable value regarding reaction to fire) of homogeneously dist

43、ributed organic material. If they contain more than 1 % of organic material by mass or by volume, they shall be tested and classified according to EN 13501-1. 4.5.2.2 Fire resistance a) Fire resistance of single partitions The values in use established in previous tests to be confirmed or determined

44、 subsequently on the basis of EN 1364-1 are given in Table 1. EN 15318:2007 (E) 9 Table 1 Fire resistance: values in use Thickness Density class E min. Solid blocks E min.

46、 based on extrapolation of a close solution. b) Fire resistance of composite partitions and other gypsum block structures For cases not covered above, the structure shall be the subject of a test and classification according to EN 13501-2. This test may be replaced by the opinion of a laboratory bas

47、ed on extrapolation of a related solution. 4.5.3 Safety in use 4.5.3.1 General Gypsum block partitions are self-supporting and present no risk to the safety of the user as long as the requirements of this subclause are met. The maximum dimensions indicated in the tables below result from EN 15318:20

48、07 (E) 10 just mechanical considerations. This allows the structure to withstand the normal and high mechanical stresses. The tables below define the maximum permitted dimensions for gypsum blocks of all densities. Dimensioning of the partition is obtained by dividing into panels, the maximum dimens

49、ions of which are indicated according to the stress levels in Table 2 and Table 3. The panels are limited by the structure of the building or stiffeners as shown in Figures 1, 2 and 3.
