Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 8659-2008 "butadiene rubber (BR) 9000", compared with GB/T 8659-2008 main technical changes
as follows.
--- Revised the normative reference document (see Chapter 2, Chapter 2 of the.2008 edition);
--- Revised the appearance requirements (see Table 1, 3.1 of the.2008 edition);
--- Increased vulcanization properties (see Table 1);
--- Revised the note in Table 1 as a clause (see Table 1, Table 1 of the.2008 edition);
---Modified inspection rules (see Chapter 4, Chapter 4 of the.2008 edition);
---Added logos and accompanying documents (see Chapter 5);
---Modified packaging, marking, storage and transportation (see Chapter 6, Chapter 5 of the.2008 edition);
--- Removed Appendix A.
This standard was proposed by the China Petroleum and Chemical Industry Federation.
This standard is under the jurisdiction of the National Rubber and Rubber Products Standardization Technical Committee (SAC/TC35).
This standard was drafted. China Petroleum and Chemical Corporation Beijing Yanshan Branch, China National Petroleum Corporation Petroleum
