In this standard timber includes so

19、lid timber, glued laminated timber and wood-based products. The test method applies to all types of nails, screws and staples excluding screws with fully threaded shank. 2 Normative references The following documents, in whole or in parts, are normatively referenced in this document and are indispen

30、imber and wood-based products The solid timber shall be selected in accordance with the method given in EN ISO 8970:2010. The specification of the LVL, glued laminated timber and wood-based products shall be established. The products used for the individual test pieces shall be representative of the

31、 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 methods 6.1 General The moisture content and density of the timber or wood-based products at test shall be determine

32、d as specified in ISO 13061-1, ISO 13061-2, EN 322 and EN 323 as appropriate. 6.2 Conditioning The test pieces shall be manufactured with the timber or wood based products at an equilibrium moisture content corresponding to (20 2) C and (65 5) % relative humidity. The material is conditioned when it

33、 attains constant mass. Constant mass 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 % off the mass of the material. For certain investigations other moisture conditioning can be appropriate, and shall be

34、 reported. 6.3 Fabrication of test pieces The axis of the fastener shall be perpendicular to the surface, see Figure 3. The insertion of fasteners shall follow normal preparation (e.g. pre-boring) and practice. The test piece size shall be as given in Table 1. Where the test pieces are of solid timb

35、er, half of the fasteners shall be inserted radially to the growth rings and half tangentially to the growth rings. Test shall be made with test pieces with crn= 30. If wood-based products are included in the test piece the test shall be carried out at either crn= 30 or crn= 60, whichever gives the

36、smallest load carrying capacity.
