EN 14566:2008+A1:2009 (E) 6 1 Scope This European Standard specifies the characteristics and performance of mechanical fasteners, including nails, screws and staples, intended to be used for the fixing of gypsum plasterboard, gypsum boards with fibrous reinforcement, products from secondary processing and suitable ancillary products as shown in Figure 2, to timber and metal, as appropriate, in building construction works. The fasteners secure the board to the framing enabling its surface to be finished by jointing or plastering to receive decoration. They can also be used for the construction of the framing and for the connection between substructure and load bearing components and for fixing boards together. Mechanical fasteners contribute to the stability of the assembly. This European Standard covers the following product performance characteristics: reaction to fire and flexural strength to be measured according to the corresponding European test methods. It provides for the evaluation of conformity of the product to this European Standard. This European Standard also covers the additional technical characteristics that are of importance for the use and acceptance of the products by the construction industry and the reference tests for these characteristics. This European Standard does not cover nails, screws and staples intended for use with materials other than plasterboard and the plasterboard based products referred to above and their associated system components. 2 Normative references The following referenced documents are indispensable for the application of this document.

See !Table 2" and Table A.1. !3.1.2" plasterboard screw screw used without pilot holes for the assembly of plasterboard systems NOTE Screws which go directly into plasterboard usually have a trumpet head. They are straight and free from burrs and capable of being driven by a power operated screwdriver. See Table A.2. !3.1.3" head wide part of nail or screw used to drive the nail or screw into the materials to be joined NOTE The head of nails can be one of two types according to function (see Table A.1). The surface can be smooth or chequered. The head of screws can be domed, flat or concave depending upon its use (see Table A.2). !3.1.4" point sharp end opposite to the head which first penetrates the materials to be joined NOTE The style and shape of the nail point is formed to permit entry and penetration of the timber. !3.1.5" shank connection between the head and the point NOTE Nails have a straight shank. The diameter of the round shank can vary according to length, function and thickness of the corrosion resistant treatment. It may be plain, have indentations, be annular ring rolled or may be separately treated to improve resistance to withdrawal. !3.1.6" thread spiral extension to the shank of specific pitch and diameter appropriate to its function and use NOTE The thread may be of single or multiple lead design. !3.1.7" plasterboard staple double right angle, fastener, made from round, oval, square or rectangular wire, with two legs (shanks) usually of the same length connected by its crown (head) with the tips inclined, see Table A.4 NOTE Staples are U shaped, neatly formed and free from defects. Staples can be resin coated to increase withdrawal strength. The legs are straight and parallel and can be designed, in conjunction with the tip, to provide additional holding power when driven into substrate. The style and shape of the tips permit entry and guide and control the line and shape of the penetration of the timber or substrate. The tips have an inclined plane on one or both sides. 3.2 !Symbols and abbreviations For the purpose of simplification in product marking and performance information characteristics may be identified through the symbols and abbreviations given in Table 1.

to 350 w, no load speed (2 350 ± 350) revolutions per min; c) fixed support mounting for the power screwdriver; d) application force: Power screwdriver plus dead weight = 15 kg; e) stop watch with pre-setting to start at the commencement of drilling and stop when screw penetrates to a depth of 10 mm. This fixed depth allows all lengths of screws to be tested; f) cold rolled galvanised steel sheet (0,6 ± 0,04) mm manufactured to EN 10327 of a size large enough for
50 type N screws to be inserted without interference with one another. (See Table A.2). g) cold rolled galvanised steel sheet (2 ± 0,09) mm manufactured to EN 10327 of a size large enough for
50 type D screws to be inserted without interference with one another. (See Table A.2). 5.6.3 Procedure Select 50 screws from the batch of screws to be tested. Secure the sample metal below the mounted screwdriver. Locate the bit in the power screwdriver and engage a sample screw with the tip of the screw in contact with the metal prior to power being applied. Set the stop watch to zero. Start the drill. The watch will stop automatically after the screw has penetrated 10 mm. Note the penetration time for type N screws and repeat for the remainder or note the number of type D screws which fail to penetrate. 5.6.4 Expression of results Record for type N screws, the average drilling time and the number of screws exceeding the 1 s penetration time (see 4.4.3.3.).

Dilute the solution with distilled water to 1 000ml. 5.7.3 Procedure 5.7.3.1 Probe The electro or magnetic equipment gives direct readings. 5.7.3.2 Stripping Measure the thickness T or weight W of the product, including the coating; immerse the sample completely in stripping reagent at room temperature and leave until the coating has completely dissolved. The end of the dissolution process can be recognised by the cessation of the original brisk evolution of hydrogen. Rinse the sample in running water and, if necessary, brush to remove any loose substance which may be adhering to the surface. Dip in alcohol and quickly dry. Measure the thickness t or weight w of the base metal. The coating thickness is given by: 1/2 (T - t). The coating mass is given by: w21.

Compare the results with the producer’s declared thickness or weight and tolerances for the coating. 5.8 Determination of pull-through force 5.8.1 Principle The test is to determine the resistance against pull through provided by the head or crown of the fastener through the plasterboard. 5.8.2 Apparatus a) testing device as shown in Figure 4; b) calibrated loading machine, capable of applying a force of (1 000 ± 10) N applied at rate of (450 ± 200) N per min; c) 12,5 mm gypsum plasterboard to EN 520, of the type for which the fastener is intended to be used.
