This is Part 5 of GB/T 9766. This Part was drafted in accordance with the rules provided in GB/T 1.1-2009. This Part serves as a replacement of GB/T 9766.5-2009 Test Method for Tyre Valve - Part 5: Test Methods for Tyre Valves for Large Core Chamber. In comparison with GB/T 9766.5-2009, the main technical changes are as follows: ---The accuracy grade of the pressure gauge is modified (see 4.3; 4.3 of Version 2009); ---The valve base and test plate hole size corresponding to the tubeless valves are added (see Table 1); ---The valve hole size and plate thickness are modified (see Figure 2; Figure 2 of Version 2009); ---The valve sealing performance test is modified (see 5.1.1, 5.1.2 and 5.1.3; 5.1.1, 5.1.2 and 5.1.3 of Version 2009); ---The tubeless valve and valve hole sealing performance test is modified (see 5.2.1, 5.2.2, 5.2.3 and 5.2.4; 5.2.1, 5.2.2 and 5.2.3 of Version 2009); ---“The entrained gas during the installation is not considered as a leak” is added (see 5.1.2, 5.1.3, 5.2.3 and 5.2.4); ---The corrosion resistance test is modified (see Chapter 6; Chapter 6 of Version 2009); ---The assembly torque test is modified (see Chapter 7; Chapter 7 of Version 2009). This Part was proposed by China Petroleum and Chemical Industry Federation. Test Methods for Tyre Valves - Part 5: Test Methods for Large Core Chamber Tyre Valves1 ScopeThis Part of GB/T 9766 specifies the terms and definitions, test equipment, instruments and apparatuses of large core chamber tyre valves (hereinafter referred to as “valves”) test, as well as sealing performance test, corrosion resistance test and assembly torque test. This Part is applicable to the test of valves for pneumatic tyres of large-scale construction machinery, such as: heavy-duty dump trucks, loaders, excavators, scrapers, road rollers and graders, etc.2 Normative ReferencesThe following documents are indispensable to the application of this document.

Put the test device into the water; maintain the axis of the valve base and the axis of the valve core at the same horizontal positon, and the distance from the water surface shall not exceed 30 mm. Introduce (35 5) kPa of compressed air; within 60 s, observe and record whether there are bubbles escaping from the joints between the valve body or the core sleeve and the valve core, the valve body and the valve base, the core sleeve or coupling sleeve and the valve base. The entrained gas during the installation is not considered as a leak. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
