Dimensions and tolerances are in millimetres. 4.2 Material Hardness Surface condition Surface coating Dimensions and tolerances 4.2.1 Material The material qual
20、ity is left at the manufacturers option as specified in the product standard. However, materials used shall be either rolled, drawn or forged steel with chemical composition, and ascertain adequate strength composition and good impact characteristics. 1) Published as ASD Prestandard at the date of p
21、ublication of this standard. EN 4359:20065 4.2.2 Hardness The drivers shall be hardened throughout to Rockwell C56 to C64 for all sizes. Hardness tests shall be performed in accordance with 8.2.3.4. 4.2.3 Surface condition All drivers shall be free from pitting, deposits, forging flashes, cracks, sp
22、lits, burrs and other defects liable to impair their characteristics and their endurance and to cause injury to operators. Surfaces shall be smooth to adequately determine all dimensions specified. 4.2.4 Surface coating A rust preventative coating adequate for interim storage shall be applied. 4.2.5
23、 Dimensions and tolerances Drivers shall conform to dimensions and tolerances of the product standard and shall be inspected in accordance with 8.1. 5 Performance 5.1 Torque load The drivers, when tested as specified in 8.2.3, shall conform to 60 % of the torque load requirements of Table 1, for the
24、 specified driver size (recess code). In the case of double ended drivers, EN 4358, both ends shall be tested. 5.2 Toughness The drivers shall be subjected to a toughness test to determine whether or not the material is able to absorb energy up to its rupture point. The test shall be conducted as sp

26、spection, unless otherwise specified in the contract or purchase order, is the responsibility of the supplier as specified herein. 7 Qualification and acceptance procedures See Tables 2 and 3. The strength and endurance of the drivers are tested in accordance with the procedures described in Clause
27、8. 8 Test methods 8.1 Visual and dimensional examination Each driver shall be selected in accordance with Table 4 sampling data and shall be visually examined for conformance. Driver tip dimensions as specified in the product standard shall be inspected with GO and NO GO gauges specified in Figure 1
28、 and Table 6. EN 4359:20067 8.2 Acceptance 8.2.1 General The aim of the acceptance tests is to check as simply as possible that drivers from different batches satisfy the requirements of this standard. 8.2.2 Acceptance test The acceptance test shall be conducted on drivers chosen at random from diff
29、erent production batches in accordance with Table 4 or 5. 8.2.3 Proof load torque test 8.2.3.1 Test fixtures The drivers shall be tested in a fixture having in its centre the correct size and form of the six lobe drive-internal recess in accordance with EN 3911. The fixture shall be heat treated to
30、a hardness of Rockwell C65 minimum. 8.2.3.2 Application of test loads The loads specified in 5.1 shall be applied with calibrated torque wrenches, or suitable equivalent torque machines. Drivers must withstand fifty (50) alternating applications in a clockwise and the counter clockwise directions, w
31、ith applied loads of 60 % of minimum torque values specified in Table 1. Failure of the drivers to do such tests, shall be cause for rejection. If the fixture fails, repeat the test with a new driver and a new fixture. 8.2.3.3 Toughness test Drivers that have successfully completed the requirements
32、of 8.2.3.2, shall be torqued to failure utilising test fixtures of 8.2.3.1. Test loads shall be applied in accordance with 8.2.3.2. Torque shall be applied until a fracture or definite bend of the driver occurs. At least one driver shall have torque applied in the counter clockwise direction. If fra
33、cture occurs, the pieces shall be refitted and the driver shall show that a definite, noticeable permanent set occurred prior to failure. If fracture or a permanent set occurs prior to the application of torques listed in Table 1, the driver shall be considered as not having passed the test. If a fr
34、acture occurs after the torque values listed in Table 1 have been exceeded but with no permanent set of the fractured driver (brittle failure), the driver shall be considered as not having passed the test. 8.2.3.4 Hardness test Drivers shall be tested in accordance with ISO 6508-1. Surfaces shall be
35、 suitably ground for these tests, with any coating, decarburisation or hardness cases removed before testing. The hardness of the driver shall be taken as near to the driver tip as practically possible. The hardness shall conform to 4.2.2. 9 Marking/packing 9.1 Identity marking The identity marking
36、is specified in the product standard and/or detail drawing. 9.2 Packaging The packaging of the drivers is left to the option of the manufacturers.
