Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 7811-2007 "Rolling parameter symbol", compared with the present standard GB/T 7811-2007, in addition to editing
Modifications, mainly technical changes are as follows.
--- Modify some normative references (see Chapter 2, Section 2 of the 2007 edition);
--- Increased terms and definitions (see Chapter 3);
--- Modification and deletion of some parameter symbols (see Table 1 to Table 10, the 2007 edition of the Tables 1 to 10).
This standard uses the translation method identical with ISO 15241.2012 (E) "Rolling Parameter Symbol."
Correspondence between the consistency of the standards of international documents and normative references of the following documents.
--- GB/T 4199-2003 Rolling defined tolerances (ISO 1132-1.2000, MOD)
--- GB/T 6391-2010 Rolling bearings - Dynamic load ratings and rating life (ISO 281.2007, IDT)
--- GB/T 6930-2002 Rolling Vocabulary (ISO 5593.1997, IDT)
The standard proposed by China Machinery Industry Federation.
This standard by the National Standardization Technical Committee of Rolling (SAC/TC98) centralized.
