14、y of Test MethodThe test specimen is tested in a machine designed to apply a crushing force upon the specimenin a plane through the vertical axis extending along the length of the specimen.4.2 Significance and UseThe crushing test method shall be either a quality control test performed to establish
15、that the finished,shippable pipe has sufficient strength to withstand the crushing loads stated in the specifications or a proof of design test performedto prove the adequacy of design.4.3 Apparatus:4.3.1 The testing machine shall be of any type of sufficient capacity and shall be capable of providi
16、ng the rate of loadingprescribed in 4.5.3.4.3.2 The testing machine shall be substantial and rigid throughout, so that the distribution of the load will not be affectedappreciably by the deformation or yielding of any part.4.3.3 The three-edge-bearing method of loading shall be used. The test specim
17、en shall be supported on a lower bearing of twoparallel longitudinal strips and the load applied through an upper beam (Fig. 1, Fig. 2, Fig. 3, and Fig. 4). At the option of themanufacturer, either or both the lower bearing and the upper bearing shall extend the full length or any portion of the len
18、gth ofthe specimen.4.3.4 The lower bearings shall consist of wood or hard rubber strips. Wooden strips shall be straight, have a cross section ofnot less than 50 mm in width and not less than 25 mm nor more than 38 mm in height and shall have the top inside corners roundedto a radius of 13 mm. Hard
19、rubber strips shall have a durometer hardness of not less than 45 nor more than 60. They shall berectangular in cross section, having a width of not less than 50 mm, a thickness of not less than 25 mm nor more than 38 mm,and shall have the top inside corner rounded to a radius of 13 mm.4.3.5 The low
20、er bearing strips shall be fastened to a wooden or steel beam or directly to a concrete base, any of which shallprovide sufficient rigidity so that the deflection is not greater than 1720 of the specimen length when the maximum load is applied.The rigid base shall be at least 150 mm wide. The interi
21、or vertical sides of the strips shall be parallel and spaced a distance apartof not more than 25 mm per 300 mm of specimen diameter, but in no case less than 25 mm. The bearing faces of the lower stripsshall not vary from a straight line vertically or horizontally by more than 2.5 mm/m of length und
22、er no load.4.3.6 The upper bearing shall be a rigid wood beam with or without an attached hard rubber strip. The wood shall be sound,free of knots, and straight and true from end to end. It shall be fastened to a steel or wood-faced steel beam of such dimensionsthat deflections under maximum load wi
23、ll not be greater than 1720 of the specimen length. The bearing face of the upper bearingshall not deviate from a straight line by more than 2.5 mm/m of length. When a hard rubber strip is used on the bearing face itshall have a durometer hardness of not less than 45 nor more than 60, and shall have
24、 a width of not less than 50 mm and a thicknessof not less than 25 mm nor more than 38 mm and shall be secured to a wood beam meeting the above requirements.4.3.7 If mutually agreed upon by the manufacturer and the owner prior to the test, before the specimen is placed, a fillet ofplaster of paris n
