GB/T 13202-2015Series of motorcycle rims (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 13202-2007 "motorcycle rims Series", compared with the GB/T 13202-2007, the major technological change as follows.

--- Remove the Introduction (see 2007 edition of the Introduction);

--- Increasing the rim contour of the production model and contour testing method references (see chapter 2 and 12.2.3);

--- The "rim type, size, terminology and specifications" to "Terms and Definitions", "symbol" and the "classification and nomenclature" 3 Section (see Chapter 3 ~ Chapter 5, Section 3 of the 2007 edition);

--- An increase of 5 ° ramps at the end of the bead seat of the rim (MT type) may be used in a tubeless tire labeling requirements (see 5.1);

--- Increased and filled the legend symbols and terminology standards appear (see Chapter 4);

--- Modified rim specification illustrate the characteristics described in the table, and corrected the mistake in two widths code (see Table 1, 2007 edition

Table 1);

--- Increased cylindrical bead seat rim (WM type) calibration perimeter (see Table 3);

--- Adds two new specification codenamed nominal diameter of 4 to 12 MT type rim, and the code for the nominal diameter of 4 to 10 G value 2.15MT rim modified by 14.0mm to 10.5mm (in Table 4, 2007 edition Table 4);

--- Increasing the nominal diameter of code for MT type wheel rim 13 to 24 5 new specifications (see Table 5);

--- Remove the 5 ° ramps at the end of the bead seat of the rim (MT type) contour "bottom rim contour - Select 1" (see the 2007 edition of the FIG. 3 and

Table 6);

--- An increase of 5 ° ramps at the end of the bead seat of the rim (MT type) of "no hump rims have only can be used on tubeless tires" requirement (See 7.4);

--- Modified 5 ° ramps at the end of the bead seat of the rim (MT type) in 15M/C and 23M/C calibration diameter/circumference hump, an increase of 11, 22M/C and 24M/C diameters, and removed the spiked M/C suffix Year rim produced by transitional provisions (see Table 7, 2007 edition Table 8);

--- Increasing the split rim (DT type) in order to calibrate the diameter of a nominal diameter of code 12 (see Table 11);

--- Increased the various structures of the rim valve hole values \u200b\u200brequired text (see Chapter 9);

--- To the rim diameter and the calibration standard circle diameter (measured bead phi8) increased nominal diameter codenamed 11,22M/C, 24M/C's Value, modify the value of 23M/C and remove the transitional provisions spiked M/C suffix by the rim of the year of production; the use of measurement Pearl phi10 increases the value of the nominal diameter of code 11 (see Table 14 and Table 15, the 2007 edition of Tables 15 and 16).

This standard uses redrafted modification method using ISO 4249-3. section "motorcycle tires and rims (code represents series) Section 32010 Score. rim ", ISO 5995-2. 1988" moped tires and rims - Part 2. rim ", ISO 6054-2:1990" motorcycle tires and rims (code represents series) codenamed diameter of 4 to 12 - Part 2. the rim. " the ISO standard as compared with the respective standards in the structure have more adjustments are listed in Appendix A of this standard and above standard ISO each chapter Article ID Control List.

Exist as compared with the present standard ISO technical differences between the various standards, terms of these differences has been involved in space bit by its outside margin Opposed to a single vertical line (|) was marked Appendix B gives a list of corresponding technical differences and their causes.

This standard also made the following editorial changes.

--- Changes the above ISO standard name for each standard.

The standard proposed by China Petroleum and Chemical Industry Association.

The standard tire rim by the National Standardization Technical Committee (SAC/TC19) centralized.
