35、rising two plates of equal nominal thickness, axially aligned and assembled into a single lap joint by means of the test rivet, as shown in Figure A.1. The diameters of the test holes are as given in Table A.1. The plates are of alloy steel, hardened and tempered to within the range 46 HRC to 50 HRC
36、 with surface finish not exceeding 3.2 m. The test fixture shall be assembled as follows. Install the rivet in accordance with the manufacturers recommendations using the tool supplied by the manufacturer. Ensure that the total thickness of the joint is not less than 1.0 times the nominal rivet diam
37、eter when testing protruding head rivets, or 1.5 times the rivet diameter when testing countersunk head rivets, nor greater than the maximum grip length of the test rivet concerned. For rivets which have a maximum grip length less than the minimum total joint thickness specified above, use the maxim
38、um grip length as the total joint thickness.

39、m/min. A.1.2 Procedure Assemble the test fixture between the jaws of the tensile testing machine, taking care to ensure that the tensile load will be transmitted in a straight line through the test rivet. Maintaining a free running speed within the specified range, apply a tensile load to the test f
40、ixture and increase the loading until failure of the rivet occurs. Record the maximum load applied (measured in N) as being the shear load of the rivet. NOTEIf hydraulic testing machines are used care should be taken to locate the fixture at the centre of the piston. A.2 Tensile test A.2.1 Apparatus

42、mbled as follows. Install the rivet in accordance with the manufacturers recommendations using the tool supplied by the manufacturer. Ensure that the total thickness of the joint is not less than 1.0 times the nominal rivet diameter when testing protruding head rivets, or 1.5 times the rivet diamete
43、r when testing countersunk head rivets, nor greater than the maximum grip length of the test rivet concerned. For rivets which have a maximum grip length less than the minimum total joint thickness specified above, use the maximum grip length as the total joint thickness. A.2.1.2 Tensile testing mac

A.2.2 Procedure Assemble the test fixture between the compression heads of the tensile testing machine. Maintaining a free running sp
45、eed within the specified range, apply a load to the test fixture and increase the loading until failure of the rivet occurs, either when the rivet body fractures or the rivet is pulled through one of the plates. Record the maximum load applied (measured in N) as being the tensile load of the rivet.
46、NOTEIf hydraulic testing machines are used care should be taken to locate the fixture at the centre of the piston.
