Among them, for dated references, only the edition corresponding to that date applies to this document. For undated references, the latest edition (including all amendments) applies to this document. GB/T 528 Rubber, vulcanized or thermoplastic - Determination of tensile stress- strain properties GB/T 531.1 Rubber, vulcanized or thermoplastic - Determination of indentation hardness - Part 1.Durometer method (Shore hardness) GB/T 1689 Rubber vulcanized - Determination of abrasion resistance (Akron machine) GB/T 2941 Rubber - General procedures for preparing and conditioning test pieces for physical test methods GB/T 3512 Rubber, vulcanized or thermoplastic - Accelerated ageing and heat resistance tests - Air-oven method GB/T 6326 Tyre terms and definitions3 Terms and definitionsThe terms and definitions defined in GB/T 6326 apply to this document.4 Technical requirements4.1 The size designation, dimensions, and load capacity of tyres should comply with the provisions of GB/T 10823. 4.2 The physical mechanical properties of tyres shall meet the requirements in Table 1. 4.4 The tyres shall be subjected to the endurance test according to the requirements of 5.5.After the end of any one of the 1st to 8th test stages, there shall be no defects such as delamination between the rubber layers, swelling, cracks, chipping, abnormal deformation of the carcass, and liquid flow out of the temperature measuring hole.5 Test methods5.1 The outer diameter, section width, and static load performance of the tyres shall be tested according to the provisions in Appendix A and Appendix B. 5.2 For the tensile strength and elongation at break of each layer of rubber sample, it shall be sampled according to the provisions in Appendix C; tested according to the provisions of GB/T 528.6 Marking6.1 Each tyre sidewall shall have the following markings.Appendix A(Normative) Measurement methods for overall dimensions of tyres A.1 Measurement items The outer circumference and section width of the tyre. A.2 Measurement conditions A.2.1 After the tyre is vulcanized, it shall be parked at room temperature for more than 48 h. Before testing, the tyre and rim assembly shall be parked at a temperature of 18 °C~36 °C for at least 24 h. A.2.2 Measurement tools and their accuracy requirements are as follows. A.3 Measurement methods A.3.1 Outer circumference of tyre Use a metal tape measure to wrap around the tyre along the centerline of the crown or near the highest point of the centerline; measure the outer circumference. The unit of measurement is mm and round up to an integer. According to formula (A.1), obtain the outer diameter.Appendix B(Normative) Test method for static load performance of tyres B.1 Test conditions B.2 Measurement and calculation B.2.1 Install the tyre conforming to the provisions of B.1 on the testing machine. According to the provisions of Appendix A, measure the outer diameter and section width of the tyre. B.2.2 Apply printing oil to the pressure-bearing part of the tyre; lay a piece of white paper between the tyre and the pressure-bearing plane; start the testing machine; apply the load to the tyre to the specified value; after 15 min, measure the static load radius and section width under load of the tyre. B.2.3 After completing the measurement in B.2.2, take out the imprint paper; use the planimeter to obtain the area S (cm2) of the imprint; round up the calculation. B.2.4 The amount of deflection is calculated according to formula (B.1). ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
