21、7-05 6 5 Torque testing 5.1 General For combined wrenches (for example, reference nos. 1 1 01 05 0 and 1 1 01 06 0), the box wrench side shall be tested in accordance with Table 3, Series A, and the open end wrench side shall to be tested in accordance with Table 3, Series C. 5.2 Method The wrench o
22、r the socket shall be fully engaged in a hexagon test mandrel as shown in Figure 1. The height, h, and the width across corners, emin., of the mandrel are specified in Table 3. Smoothly apply the load until the minimum testing torque as given in Table 3 is reached. The nominal across-flats dimension
23、 of the test mandrel shall be equal to the nominal dimension, s, with a tolerance of h8. The mandrel shall be hardened to not less than hardness 55 HRC. A device in which the mandrel can be rotated at a certain torque determined with an accuracy of 2,5 % may also be used for this test. Following the
24、 application of the minimum test torsion torque, any possible damage or deformation shall not affect usability of tool. Figure 1 Test mandrel height, width across flats and width across corners DIN ISO 1711-1:2007-05 75.3 Test of box wrenches or open jaw wrenches Apply the load as far along the shaf
25、t of the wrench as possible, perpendicular to its longitudinal axis. Use an extension tube when testing large wrenches. Load the wrench once in each direction during the test. For open jaw wrenches, the head shall remain perpendicular to the mandrel axis during the test. For box wrenches, the axis o
26、f the head shall remain perpendicular to the mandrel axis during the test. 5.4 Test of socket wrenches Apply the load as far along the shaft of the wrench as possible, perpendicular to its longitudinal axis. Use an appropriate test device that will safely test large wrenches. The axis of the socket
27、wrenches and the axis of the mandrel shall remain coaxial during the test. 5.5 Test of hand-operated square drive sockets A square mandrel of hardness not less than 55 HRC shall be used for driving the socket. The nominal across-flats dimension of this mandrel shall be equal to the maximum dimension
28、, with a tolerance of h8, of the corresponding driving square. The axes of the two mandrels and the axis of the socket shall remain coaxial during the test.
