Figur
18、e 1 Family of gypsum products EN 13915:2007 (E) 5 Figure 2 Family of ancillary products EN 13915:2007 (E) 6 1 Scope This European Standard specifies the characteristics and performance of prefabricated panels made of gypsum plasterboard facings complying with EN 520 and a cellular paperboard core in
19、tended to be used as a lightweight partition, lining and encasement for general use in buildings. This standard covers the following characteristics: reaction to fire, water vapour permeability, flexural strength (breaking load) and thermal resistance to be measured according to the corresponding Eu
20、ropean test methods. This Standard covers only prefabricated panels installed so that the core is not exposed. The following performance characteristics are linked to systems assembled with prefabricated panels made of gypsum plasterboard facings and a cellular paperboard core: shear strength, fire
21、resistance, direct airborne sound insulation, acoustic absorption and air permeability to be measured according to the corresponding European test methods. If required, tests should be done on assembled systems simulating the end use conditions. This document covers also additional technical charact
22、eristics that are of importance for the use and acceptance of the product by the Building Industry. It provides for the evaluation of conformity of the products to this document. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、terms and definitions apply. 3.1 prefabricated gypsum plasterboard panel panel that is made up of two gypsum plasterboards according to EN 520, possibly up to 15 mm thick, bonded to both sides of a cellular paperboard core NOTE It is commonly named “panel“ in this standard. 3.2 panel facing exposed
31、surface of plasterboard to receive either coating or finishing 3.3 length dimension of the panel parallel to the paper covered edges, measured on the panel facing 3.4 width dimension of the panel perpendicular to the paper covered edges, measured on the panel facing 3.5 thickness distance between th
32、e panel facings 4 Requirements 4.1 Fire behaviour 4.1.1 Reaction to fire When subject to regulatory requirements, prefabricated gypsum plasterboard panels shall be tested and classified in accordance with EN 13501-1. Prefabricated gypsum plasterboard panels tested according to EN 13823 (SBI test) sh
33、all be mounted and fixed in accordance with Annex B or when the producer wishes to claim performance for a specific intended use, the mounting and fixing shall be representative of that intended use. Prefabricated gypsum plasterboard panels tested according to EN ISO 11925-2 (Ignitability) shall be
34、tested with surface attack only due to the fact that edge attack cannot occur in end use conditions. 4.1.2 Fire resistance NOTE Resistance to fire is a characteristic dependent on an assembled system and not of the product in isolation. When required, the fire resistance of a system including prefab
35、ricated gypsum plasterboard panels shall be classified according to EN 13501-2. EN 13915:2007 (E) 8 4.2 Impact resistance NOTE Impact resistance is a characteristic dependent on an assembled system and not of the product in isolation. When the manufacturer wishes to declare the impact resistance per
36、formance of a system that includes prefabricated gypsum plasterboard panels, the performance of the system shall be determined in accordance with ISO 7892. 4.3 Water vapour permeability (expressed as water vapour resistance factor) Water vapour permeability is not a characteristic of heterogeneous p
37、roducts like panels therefore water vapour resistance is used instead. When the manufacturer wishes to declare a performance for moisture diffusion control, tabulated design values of water vapour resistance for gypsum plasterboards given in EN 12524 may be used for calculation. Alternatively, the w
38、ater vapour resistance factor shall be determined in accordance with EN ISO 12572. 4.4 Flexural strength (expressed as deflection under a defined load) When determined in accordance with the test method described in 5.4, the deflection shall not exceed the values given in Table 1. Table 1 Deflection
39、 values Panel thickness Deflection (max) mm mm 50 50 mm: applied load 2 500 N; thickness 50 mm: applied load 1 875 N; b) 900 mm panels: applied load 1 875 N; c) 600 mm panels: applied load 1 250 N; d) for other widths, applied load 2 083 N/m width. Read the deflection in the centre of the loaded pan
40、el when the required load is reached. 5.4.4 Expression of results Calculate the average deflection of the three specimens and compare it with the value stated in Table1. 5.5 Determination of the core adhesion 5.5.1 Principle The bonding strength between the core and the gypsum plasterboards shall be
41、 measured. 5.5.2 Apparatus Testing device allowing a loading rates of 3 kN/min (see Figure 5). 5.5.3 Procedure Cut out the 230 mm 230 mm specimens from one panel (see Figure 5). In the case of discontinuous core panels, the specimen shall include a complete section of core. Introduce the boards of t
42、he specimen in clamps. Reduce the testing surface to 200 mm 200 mm by removing the core from the perimeter. Apply the tensile load continuously at the rate of 3 kN/min until rupture. Record the maximum load. Repeat for the other two specimens. EN 13915:2007 (E) 14 5.5.4 Expression of results Calcula
43、te the average adhesion of the three specimens and compare it to the values stated in 4.9. Divide the maximum load in Newtons for each specimen by the testing surface (4 104mm2) to give the core adhesion in MPa.

Condition the specimen to constant mass1). 5.6.3.2 Testing Place the specimen, face up, on the rigid table and cover it with the carbon paper (see Figure 6
47、). Then place the sphere between the clamps of the support at 500 mm 5 mm high from the gypsum plasterboard (see Figure 6). Let the sphere fall down the specimen (see Figure 6). Then take off the carbon paper and measure to the nearest mm, the diameter of the coloured impact onto the gypsum plasterb
