14、ng machine shall be of any type of sufficientcapacity and shall be capable of providing the rate of loadingprescribed in 4.5.3.4.3.2 The testing machine shall be substantial and rigidthroughout, so that the distribution of the load will not beaffected appreciably by the deformation or yielding of an
15、y part.4.3.3 The three-edge-bearing method of loading shall beused. The test specimen shall be supported on a lower bearingof two parallel longitudinal strips and the load applied throughan upper beam (Fig. 1, Fig. 2, Fig. 3, and Fig. 4). At the optionof the manufacturer, either or both the lower be
16、aring and theupper bearing shall extend the full length or any portion of thelength of the specimen.4.3.4 The lower bearings shall consist of wood or hardrubber strips. Wooden strips shall be straight, have a crosssection of not less than 50 mm in width and not less than 25mm nor more than 38 mm in
17、height and shall have the topinside corners rounded to a radius of 13 mm. Hard rubber stripsshall have a durometer hardness of not less than 45 nor morethan 60. They shall be rectangular in cross section, having awidth of not less than 50 mm, a thickness of not less than 25mm nor more than 38 mm, an
18、d shall have the top inside cornerrounded to a radius of 13 mm.4.3.5 The lower bearing strips shall be fastened to a woodenor steel beam or directly to a concrete base, any of which shallprovide sufficient rigidity so that the deflection is not greaterthan1720 of the specimen length when the maximum
19、 load isapplied. The rigid base shall be at least 150 mm wide. Theinterior vertical sides of the strips shall be parallel and spaceda distance apart of not more than 25 mm per 300 mm ofspecimen diameter, but in no case less than 25 mm. Thebearing faces of the lower strips shall not vary from a strai
20、ghtline vertically or horizontally by more than 2.5 mm/m of lengthunder no load.4.3.6 The upper bearing shall be a rigid wood beam with orwithout an attached hard rubber strip. The wood shall be sound,free of knots, and straight and true from end to end. It shall befastened to a steel or wood-faced
21、steel beam of such dimen-sions that deflections under maximum load will not be greaterthan1720 of the specimen length. The bearing face of the upperbearing shall not deviate from a straight line by more than 2.5mm/m of length. When a hard rubber strip is used on thebearing face it shall have a durom
22、eter hardness of not less than45 nor more than 60, and shall have a width of not less than 50mm and a thickness of not less than 25 mm nor more than 38mm and shall be secured to a wood beam meeting the aboverequirements.4.3.7 If mutually agreed upon by the manufacturer and theowner prior to the test
23、, before the specimen is placed, a fillet ofplaster of paris not exceeding 25 mm in thickness shall be caston the surface of the upper and lower bearings. The width ofthe fillet cap, upper or lower, shall be not more than 80 mm/mof the specimen diameter, but in no case less than 25 mm.4.3.8 The equi
24、pment shall be so designed that the load willbe distributed about the center of the overall length (L1)ofthespecimen (Fig. 1, Fig. 2, Fig. 3, and Fig. 4).At the option of themanufacturer, the center of the load shall be applied at anypoint of the overall length (L1) of the specimen. The load shallbe
