31、loads of swaged collar grooved rivets A.1 Shear test A.1.1 Apparatus A.1.1.1 Test fixture comprising 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
32、A.1. The plates are of alloy steel, hardened and tempered to within the range46HRC to50HRC with surface finish not exceeding3.2m. 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
33、 that the total thickness of the joint is not less than1.0times the nominal rivet diameter when testing protruding head rivets, or1.5times 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 gr
34、ip length less than the minimum total joint thickness specified above, use the maximum grip length as the total joint thickness. Table A.1 Diameter of holes for rivet tests A.1.1.2 Tensile testing machine, capable of applying a tensile load through self aligning grips and fitted with a cross head, t
35、he free running speed of which shall not be less than7mm/min nor greater than13mm/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 f
36、ree running speed within the specified range, apply a tensile load to the test fixture 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
37、locate the fixture at the centre of the piston. A.2 Tensile test A.2.1 Apparatus A.2.1.1 Test fixture, comprising two alloy steel plates, of equal nominal thickness and hardened and tempered within the range46HRC to50HRC, and assembled by means of the test rivet, as shown in Figure A.2. The diameter
38、 of the test holes are as given in Table A.1. 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 than1.0times the nominal rivet di
39、ameter when testing protruding head rivets, or1.5times 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
40、um grip length as the total joint thickness. A.2.1.2 Tensile testing machine, capable of applying a compressive load and fitted with a cross head, the free running speed of which shall not be less than7mm/min nor greater than13mm/min. A.2.2 Procedure Assemble the test fixture between the compression
41、 heads of the tensile testing machine. Maintaining a free running speed 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 l
42、oad applied (measured in N) as being the tensile 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.3 Accuracy and repeatability of testing machines The relative accuracy of testing machines shall not exceed 3.0%, a
43、nd shall not exceed3.0% for repeatabiliy.

Such holes should be located on the longitudinal centreline of the plate, and centre distances between adjacent holes should be at least four times the diameter of the larger hole.
