Use two test pieces or test bushings of the same thickness as the test piece to form a test piece, and then rivet the test piece according to the previous installation sequence. The total thickness of the test piece should not exceed the maximum length specified for the riveted test piece. 3.3 Test Procedure
The test piece shall be mounted on a testing machine conforming to F/13-22 or GM/1591 or JV937. The test piece shall be automatically centered on the tensile testing machine and shall be able to center the shear test piece. The load shall be applied continuously at a rate not less than 7 m/min and not less than 13 mm/min until the test piece is damaged.

However, the maximum load cannot be determined under the condition of the maximum load. c) If the load is less than the specified minimum shear load or tensile load, the test plate or bushing is replaced, then the acceptance test must be agreed upon. d) If the rivet is damaged before reaching the specified minimum shear load or tensile load, the nail does not pass this test. 4.1 Test strength 4.2 Test fixture 4.3 Test fixture 4.4 Test fixture 4.5 Test fixture 4.6 Test fixture 4.1 Test strength 4.2 Test fixture 4.3 Test fixture 4.4 Test fixture 4.5 Test fixture 4.2 ...

Example of a suitable test fixture for rivet tensile test
That is, the test piece meets the requirements of 3.2.2 and the two-type test plate is shown in Figure A. After the test, the test fixture shown in Figure 1 is placed between the pressure heads of the testing machine. A.1 Rivet tensile test fixture3 Test Procedure
The test piece shall be mounted on a testing machine conforming to F/13-22 or GM/1591 or JV937. The test piece shall be automatically centered on the tensile testing machine and shall ensure that the shear test piece can be centered. The load shall be applied continuously at a rate not less than 7m/min and not less than 13mm/min until the test piece is damaged. The maximum load shall be recorded as the maximum shear or tensile load. If the shear test piece is damaged before the final shear or tensile test state, the test piece shall not pass this test. 3.4 Test of short rivets
For the test piece that is shorter than the specified 2t or 2t, the test piece shall be tested according to the maximum number of test pieces specified in the design and the test sequence shall comply with the relevant provisions of 3.2. The test society shall replace the test plate or test piece to obtain the reduced tensile force before cutting. Therefore, the following two situations apply to the test data of short rivets: 1) If the test plate and the test bushing remain intact until the damage occurs, the maximum load data is sufficient for the nail to pass the test; if the load is equal to or exceeds the specified minimum shear load or tensile load, the nail remains intact and the test plate or test bushing is damaged, then the rivet test is carried out. However, the maximum load cannot be determined under the condition of the maximum load. c) If the load is less than the specified minimum shear load or tensile load, the test plate or bushing is replaced, then the acceptance test must be agreed upon. d) If the rivet is damaged before reaching the specified minimum shear load or tensile load, the nail does not pass this test. 4.1 Test strength 4.2 Test fixture 4.3 Test fixture 4.4 Test fixture 4.5 Test fixture 4.6 Test fixture 4.1 Test strength 4.2 Test fixture 4.3 Test fixture 4.4 Test fixture 4.5 Test fixture 4.2 ... The test should be carried out with a certain degree of tolerance. The test piece must be guaranteed to have a small area of 1) 25mm.m. The through hole (4 diameter) for rivet installation should be installed with tools or removal mechanisms, and installed according to the installation procedures recommended by the manufacturer. The punch should be 5 smaller than the pin diameter. The hole on the test pad (the connector is placed on it) should have a rivet head, but its diameter should not be greater than 2 mesh points. d2 d)
4.3 During the test, the test tool will be installed on the testing machine of R/T72. G/T16191 or JB/T375. The testing machine is equipped with a lower force head as shown in Figure 6. The cutting force will be continuously applied to the rivet along the mandrel without impact. The design continues until the rivet head starts to move against the rivet body. The test depth shall not be less than ? mm/in and not more than 13 mm/in. The maximum load before the nail head starts to move shall be recorded and used as the load for the nail head to be fixed.
5 Nail core removal force test: Steel rivet (previous)
5.1 Test principle
The nail head of the steel rivet is loaded along the mandrel axis until the pin core is removed.
5.2 Test limit
The core removal force test fixture is shown in Figure
GH/T3098.18—2004/TSQ14589;2000!, in case,
Figure 7, the wick removal force test fixture can be made of steel or multiple steel, but the total depth is 10mm. The single plate rate shall not be less than 1.mr, and the test requirements shall have a certain width to ensure that the test piece is the same as the national small rigid diameter D = 25mm: the test pole is installed with the price of the nail. Direct inspection (4) should be reported in Table 2. The diameter of the hole on the test plate (test and the rivet test piece on it shall not be larger than the maximum diameter of the
