Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 14211-2010 "Mechanical Seal Test Method". This standard is compared with GB/T 14211-2010, except for editing
The main technical changes outside the sexual modification are as follows.
--- Added normative references (see Chapter 2);
--- The factory test has increased the air tightness test (see 4.1.2, 4.2);
--- Increased the type of test media (see Table 1, Table 2, 4.1 of.2010 edition);
--- The test method is subdivided according to the sealing arrangement and the transport medium (see Chapter 4, Chapter 5, Chapter 3 of the.2010 edition);
--- Removed the contents of the appendix mechanical seal test report (see Appendix A of the.2010 edition).
This standard was proposed by the China Machinery Industry Federation.
This standard is under the jurisdiction of the National Mechanical Sealing Standardization Technical Committee (SAC/TC491).
