This Document replaced GB/T 5334-2005 Performance Requirements and Test Methods of Passenger Car Wheels. Compared with GB/T 5334-2005, the major technical changes of this Standard are as follows besides the structural adjustments and editorial modifications. a) Change the scope of application, "This Document applies to passenger car wheels specified in GB/T 3730.1" (see Clause 1 of this Edition; Clause 1 of 2005 Edition); b) Add normative reference GB/T 3730.1 (see Clause 2 of this Edition); c) Add terms and definitions (see Clause 3 of this Edition); d) Add the requirements for test wheels (see Clause 4 of this Edition); e) Change the performance requirement index; and add the number of test samples and the performance requirement index of the spare wheel (see Clause 5 of this Edition; Clause 3 of 2005 Edition); f) Change the test method; delete the test items, test samples, preparation work, etc.; and they are re-divided into four parts. test equipment, load determination, test procedures and failure criteria; (see Clause 6 of this Edition; Clause 4 of 2005 Edition); g) Change the requirements for the test equipment; and add the requirements for the mounting surface of the test wheel connectors (see 6.1.1 and 6.2.1 of this Edition; 4.3.1 and 4.4.1 of 2005 Edition); h) Change part of the test procedure; and add the tightening torque requirements for wheel installation (see 6.1.3 and 6.2.3 of this Edition; 4.3.2 and 4.4.2 of 2005 Edition); i) Change the schematic diagram of the bending fatigue test (see Figure 1 of this Edition; Figures 1 and 2 of 2005 Edition); j) Add a schematic diagram of the radial fatigue test (see Figure 2 of this Edition). This Document revised and adopted ISO 3006.2015 Road Vehicles - Passenger Car Wheel for Road Use - Test Methods. Compared with ISO 3006.2015, this Document has many adjustments in structure. See Appendix A for a list of comparisons of structural number changes between the two documents. Compared with ISO 3006.2015, there are technical differences in this document. The terms of these differences have been marked by a vertical single line (丨) on the outer margin of the document. The technical differences and their reasons are as follows. a) Regarding normative references, this document has made adjustments with technical differences. The adjustments are collectively reflected in Clause 2 "Normative References". The specific adjustments are as follows. --- Replace ISO 3911 with GB/T 2933 equivalent to the international standard (see Clause 2 of this Edition), --- Replace ISO 3833 with GB/T 3730.1 modified to adopt international standards (see Clause 2 of this Edition); b) Change terms and definitions; change the definition of "crack"; add the definition of "wheel-tire assembly"; and delete other terms and definitions (see Clause 3 of this Edition); c) Change the informative Appendix A of ISO 3006.2015 into Clause 5 performance indicators (see Clause 5 of this Edition); d) Change the schematic diagram of the test equipment (see Figures 1 and 2 of this Edition); e) Add the technical requirements for the mounting surface of the test connector (see 6.1.1 and 6.2.1 of this Edition); f) Add the technical requirements for wheel load offset (see 6.1.4 of this Edition); g) Change the tire pressure requirements for the radial fatigue test (see 6.2.2.2 of this Edition). This Document also made the following editorial modifications. --- Change the standard name into Passenger Car – Wheels – Performance Requirements and Test Methods for Cornering and Radial Fatigue.
