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.

Prepare the timber section which should be free from knots, local grain distortion, cracks and warping. Drive
the appropriate fastener perpendicular into the timber to a depth of 20 mm. In the case of metal a depth of
10 mm is required. Fasteners have to be inserted without interference with one another.
Anchor the support plate. Apply the clamping device to the head or crown of the fastener. Attach the coupling
ring to the loading machine. Apply a progressive force at the rate of (450 ± 200) N per min to determine the
total withdrawal force.
5.4.4 Expression of results
Record the test results in Newtons and compare with the requirements of 4.4.2.4, 4.4.3.4 and 4.4.4.4.
5.5 Determination of bending behaviour
5.5.1 Principle
The fastener is clamped in such a way as to resist bending at two points A and B (see Figure 3 of
EN ISO 12777-1:2008). A force is then applied to the unclamped portion of the fastener at a set point C.
5.5.2 Apparatus
A three point loading static bend apparatus as described in EN ISO 12777-1:2008 or equivalent.
5.5.3 Procedure
Clamp the fastener under test in the position required by the particular apparatus in use.
Slowly apply a force to produce a bend in accordance with Table 5.

b) power screwdriver 300 w 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 10346 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 10346 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 4.4.3.6).
Record for type D screws, the average drilling time and the number of screws exceeding the 4 s penetration
time (see 4.4.3.6).

5.7 Determination of the thickness and/or mass of coating
5.7.1 Principle
The thickness and/or mass of the coating may be measured in two ways:
a) using electro, X-ray fluorescence system or magnetic probe (for thickness);
b) stripping method (for mass and thickness).
5.7.2 Apparatus
a) Electro, X-ray fluorescence system or magnetic probe measuring equipment or a micrometer permitting a
reading to 0,01 mm;
b) stripping reagent made by dissolving about 3,5 g of hexamethylentetramin according to EN ISO 1460 in
500 ml of concentrated hydrochloric acid. Dilute the solution with distilled water to 1 000ml.
5.7.3 Procedure
5.7.3.1 Probe
The electro, X-ray fluorescence system or magnetic equipment give 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: . (W – w) · 100 in %.
