characteristic density of the timber, expressed in kilograms per cubic metre 4 tensile strength of the fastener, expressed in newtons per square millimetre
4 Requirements
The fasteners shall be, as far as possible, of the quality allowed by the relevant manufacturing specification.
5 Test method
5.1 General
One of the two test methods shall be used: the four-point loading method (method A) or the three-point
loading method (method B). The user may choose one of these two methods, whichever is most relevant.
5.2 Method A
5.2.1 Principle
The principle of the test method involves the loading of the fastener under test as shown in Figure 1 in such a manner that the loading points do not move along the fastener and the loads remain normal to the axis of the fastener during the test. The dimensions I and 13 shall be not less than 2d. The free length of the fastener, ‘2 shall be between d and 3d.
5.2.2 Materials
Dowel-type fasteners shall be the same nails, staples, bolts, screws, dowels or the like as those used in the actual constwction.
Fo the fasteners with coatings, the coatings shall be removed before measuring the diameter and carrying out the tests.
5.2.3 Apparatus
5.2.3.1 Testing apparatus. such that the loads F2 and F4 (see Figures 1 and 2) do not deviate by more than
5 % from each other.
The bending moment diagram for the resulting yield moment M,, is shown In Figure 3.
NOTE A test apparatus that has been found suitable for this test is shown in Annex A.ISO 10984-1-2009 pdf free download.
