1 Scope
This European Standard specifies the characteristics and performance of mechanical fasteners made of steel,
including nails, screws and staples, intended to be used for the fixing of gypsum board in accordance with
EN 520, gypsum boards with fibrous reinforcement in accordance with EN 15283-1 and EN 15283-2,
composite panels according to EN 13950, products from secondary processing in accordance with EN 14190
and suitable ancillary products, 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.
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
gypsum board and the gypsum based products referred to above and their associated system components.

3 Terms, definitions, symbols and abbreviated terms
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
gypsum board nail
corrosion resistant steel wire nail with purpose made head, shank and point
Note 1 to entry: Nails can vary in head profile, material and level of corrosion resistance. See Table 3 and Table A.1.
3.1.2
gypsum board screw
screw used without pilot holes for the assembly of gypsum board systems
Note 1 to entry: Screws which go directly into gypsum board 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 1 to entry: 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 1 to entry: 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 1 to entry: 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 1 to entry: The thread may be of single or multiple lead design.
3.1.7
gypsum board 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 1 to entry: 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 abbreviated terms
For the purpose of simplification in product marking and performance information characteristics may be
identified through the symbols and abbreviations given in Table 1.

4 Requirements
4.1 Reaction to fire
Gypsum board nails, screws and staples made from steel are classified A1 (EN 13501-1) (no contribution to
fire) without testing when they are not coated with organic material.
According to Commission Decision 96/603/EC, as amended, nails, screws and staples are classified as A1
without testing if they contain less than 1 % organic material by weight or volume (whichever is the more
onerous).
When nails, screws and staples have an organic coating of more than 1 %, their contribution to reaction to fire
in end use condition is so small in the total assembly that they have no influence on the classification of the
system tested and therefore are classified as A1 without testing.
4.2 Flexural strength (expressed as bending behaviour and breaking torque)
4.2.1 Bending behaviour (for nails and staples)
When tested in accordance with 5.5 no fastener shall show signs of breakage or cracking. This applies only to
nails and staples with a minimum nominal length of 20 mm.
4.2.2 Breaking torque (for screws)
The breaking torque of the gypsum board screws shall comply with table 2.
Table 2 — Breaking torque of gypsum board screws
Nominal diameter of thread Minimum breaking torque

3,5 2,1
3,8 / 3,9 / 4,0 2,8

4,8 / 4,9 / 5,0 5,6
5,5 6,0

Breaking torque of the screw shall be tested in accordance with 5.9. No more than 10 % of the screws shall
fail.
