14、egral surface skin formed during manufacture, which has either: a) one or more surface zones with an apparent density substantially greater than that of the core material; or b) a relatively uniform density. 4 Test specimens Where the form and thickness of the finished product are known, the thickne
15、ss of the specimen shall be “as produced“. In those instances where the final form and shape of the product are unknown, or where the thickness of the part is variable, the test thickness shall be as agreed upon by the purchaser and supplier. When a test specimen is moulded ex- pressly for test purp
16、oses, the identical conditions, as specified by the material supplier for use in the production of the finished product, shall be used in- sofar as is practical. When test specimens are cut from a finished part or a part moulded expressly for test purposes, no specimen is to be cut from within an ar
17、ea closer to any edge than 20 mm. Test specimens may be cut from finished parts whose thickness is at least 10 mm. All test speci- mens shall be machined in such a manner that no irregularities are produced at the cut edges. Test specimens shall not be cut from any pad until at least 72 h have elaps
18、ed from the time of pro- duction of the test part. 5 Condltionlng and testing 5.1 Conditioning All test specimens shall be conditioned for a mini- mum of 16 h after cutting (preparation) in an atmos- phere as set forth in IS0 291. The preferred conditions are 23 “C f 2 “C and 50 % f 5 % R.H. For tro
19、pical climates, the conditions are 27 “C f 2 “C and 65 % f 5 %O R.H. Other condi- tioning atmospheres may be used as agreed be- tween the purchaser and supplier. 5.2 Testing The testing of the specimens shall be performed under the same conditions as used for conditioning the test specimens. 6 Test
20、methods All tests for material properties shall be as agreed upon between purchaser and supplier. These tests will vary from material to material depending upon the ultimate use of the finished material. It should be recognized that properties are influenced by the variation of the density in the di
21、rection of the thick- ness. Where IS0 test methods are unavailable or cannot be used for determining the property values as set forth in these clauses, national practice shall be the guiding factor. 6.1 Apparent density See IS0 845. The linear dimensions shall be measured with an accuracy of 0,Ol mm
22、 (in accordance with IS0 1923) and the mass to an accuracy of 0,l g. 6.2 Bending strength See IS0 178, which determines the bending stress and deflection at break or at 10 mm and 20 mm de- flection. If the specimen does not break (rupture) before reaching 20 mm deflection, stop the test and calcu- l
23、ate the bending stress at 10 mm and 20 mm de- flection. If the specimen breaks between 10 mm and 20 mm, report the bending stress at 10 mm as well as the deflection at break. 6.3 Impact strength The impact strength shall be determined by a falling dart test method (see IS0 6603-1). Preferably, an in
24、strumented falling dart apparatus should be used (see IS0 6603-2). 6.4 Tensile test See IS0 1926. The specimens shall be tested in the thickness as produced and with skins intact. 2 STD-BSI BS EN IS0 9054-ENGL 1999 Lh24hh 0793873 h2T 6.5 Shear test The procedure used shall be that described in IS0 1

30、 5bb E EN IS0 90641999 Annex A (normative) Direct screw withdrawal test A.l General Screw-holding tests shall be made on screws threaded into a board to measure the resistance to withdrawal in a plane normal to the face. For nu- merous applications, the withdrawal resistance of screws from the edge
31、of the board is desired. When that value is required, the screw withdrawal resist- ance in the plane parallel to the face shall be de- termined. When general information for comparing the screw withdrawal resistance of a board with that of another board or material is required, a 25 mm No. 10 wood s
32、crew shall be used. For special appli- cations, however, this procedure is adaptable to other sizes and types of screw, such as the 25 mm No. 10 type A sheet-metal screw. A.2 Test specimens A.2.1 Withdrawal perpendicular to the plane of the board Each test specimen shall be 76 mm in width and 152 mm
33、 in length. The thickness of the specimen shall be at least 25 mm, unless other considerations make it desirable to test with the thickness as man- ufactured, because local bending of the board at withdrawal may affect test results. If necessary, glue up two or more thicknesses of the board to arriv
34、e at the minimum thickness. A 25 mm No. 10 wood screw shall be threaded 17 rnm into the specimen at midwidth, at least 50 mrn from the end of the specimen. A lead hole shall be predrilled using a drill 2.8 mm in diameter. A.2.2 Wlthdrawal from the edge of the board Each test specimen shall be 63 mm
35、in width and 114 mm in length and the thickness of the specimen shall be the thickness of the board as manufactured. In some applications where several thicknesses of thinner board are laminated together, It may be de- sirable to obtain the edge withdrawal resistance of a laminated board. When this
36、is done, the specimen shall be laminated from an odd number of thick- nesses and the screw shall be located at the midthickness of the centre laminate. One half of the test specimens shall be prepared with the long dimension parallel and the other half with the long dimension perpendicular to the lo
37、ng dimension of the board in order to evaluate direc- tional properties. A 25 mm No. 10 wood screw shall be threaded 17 mm into the edge of the board at midthickness, using a lead hole predrilled using a drill 2.8 mm in diameter. It is recognized that some other lead hole diameter may give higher wi
38、th- drawal resistance values for some densities and kinds of board. Departures from this size of lead hole are nevertheless permitted, but the diameter used shall be reported. A.3 Specimens tested in the dry condition When tests are made in the dry state, the with- drawals shall be made immediately
39、after the screws have been embedded. A.4 If specimens are to be tested in the soaked condi- tion, the screws shall be embedded before the specimens are soaked. Specimens tested soaked before test A.5 Method of loading Attach the specimen-holding fixture (see figure A.1) to the lower platen of the te
40、st machine. Insert a specimen in the fixture with the head of the screw UP. Engage the head of the screw In the load-applying fixture (see figureA.l), which is equipped with a slot for easy attachment. Attach this load-applying fixture to the upper platen of the testing machine. Apply a load by sepa
41、ration of the platens of the test ma- chine. A.6 Speed of testing Apply the load to the specimen by moving the mov- able head of the test machine at a uniform rate of 1,s mm/rnin throughout the test. A.7 Test report The test report shall include the following informa- tion: a) the maximum load requi
42、red to withdraw the screw; 4 EN IS0 9064:1999 Swivel tor attachment to upper b) the diameter of lead hole actually used, and the type and size of screw: c) the direction of withdrawal, .e. surface (with- drawal perpendicular to the plane of the board) or edge (withdrawal parallel to the plane of the
43、 board); d) the thickness of the board tested; e) if a screw breaks rather than being withdrawn, this shall be noted and the test value shall not be reported as a withdrawal load. - 70 Dlmensions In mlliimetres Lwd-apply inn tixturc Hole o 20 Flat hend screv M IA 152 :I 60 I- 157 I - -I Spcclmen-hol
