The specification of the LVL, CLT and glued la
30、minated timber shall be established. The products used for the individual test pieces shall be representative of the class or range of product to which they belong and the relevant properties shall be declared. 5.2 Fasteners The specification of nails, screws or staples shall be established. 6 Test
31、methods 6.1 General The moisture content and density of the timber at test shall be determined as specified in ISO 13061-1 and ISO 13061-2 as appropriate. 6.2 Conditioning For smooth fasteners the test pieces shall be manufactured with the timber or wood-based products at an equilibrium moisture con
32、tent corresponding to (20 2) C and (85 5) % relative humidity. After manufacture the test pieces shall be stored for at least one week at (20 2) C and (65 5) % relative humidity. For all other fasteners the test pieces shall be manufactured with the timber or wood-based products at an equilibrium mo
33、isture content corresponding to (20 2) C and (65 5) % relative humidity. After manufacture the test pieces shall be stored at (20 2) C and (65 5) % relative humidity until it is conditioned. DIN EN 1382:2016-07 EN 1382:2016 (E) 7 The material is conditioned when it attains constant mass. Constant ma
34、ss is considered to be attained when, the results of two successive weightings, carried out at an interval of 6 h, do not differ by more than 0,1 % of the mass of the material. For certain investigations other moisture conditioning may be appropriate, and shall be reported. NOTE For some deciduous w
35、ood species a much longer storing period may be necessary. 6.3 Fabrication of the specimens 6.3.1 Fastener axis perpendicular to the grain The axis of the fastener shall be perpendicular to the timber surface. The insertion of fasteners shall follow normal preparation (e.g. pre-boring) and practice.
36、 The width and depth of the test piece in the direction of insertion of the fastener shall be at least (l + 5d), see Figure 3. Where the test pieces are of solid timber the insertion shall be ad random with respect to the growth rings. For LVL the direction can be taken as perpendicular to the lamin
37、ated veneer sheets. For staples, the tests shall be carried out with an angle of crn= 30. The other dimensions of the test piece shall comply with Figure 3. The fasteners shall be driven to a penetration of between 8 d and 20 d and shall be positioned as shown. NOTE The range of depth penetration is
38、 given so that the depth of penetration used in the test can be decided depending on the withdrawal resistance and the tensile capacity of the fastener. A depth of penetration of at least 12 d is appropriate to fasteners of d less than 2 mm. Figure 3 Withdrawal timber test pieces - load perpendicula
39、r to grain 6.3.2 Fastener axis parallel to the grain The axis of the fastener shall be perpendicular to the timber surface. The insertion of fasteners shall follow normal preparation (e.g. pre-boring) and practice. The length of the test piece in the direction of insertion of the fastener shall be a
40、t least (2l + 5d), see Figure 4. NOTE 1 This test method can also be used with the fasteners inserted into the timber at angles of between 0 and 90 to the grain direction. The other dimensions of the test piece shall comply with Figure 4. The fasteners shall be driven into the end grain to a penetra
41、tion of between 8 d and 20 d and shall be positioned as shown. NOTE 2 A depth of penetration of at least 12 d is appropriate to fasteners of d less than 2 mm.

Place the test piece in a device ensuring the application of the withdrawal force along the axis of the fastener or the axes of the staple legs. Any part of the supports shall be not closer to the axis of
43、 the fastener than 3 d for nails and screws and a for staples. The withdrawal test shall be performed with a constant rate of loading. When determining the withdrawal parameter fax, the rate of loading shall be such that the time taken to reach Fmaxis (60 15) s. Determine Fmaxto an accuracy of 1 %.
