Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 1216-2004 "outer diameter micrometer". This standard is compared with GB/T 1216-2004, except for editorial modifications.
In addition, the main technical changes are as follows.
--- Scope of application removed the outer diameter micrometer with a graduation value of 0.005mm (see Chapter 1, Chapter 1 of the.2004 edition);
--- Modified the definition of the outer diameter micrometer (see 3.1, 3.1 of the.2004 edition);
--- Increased the type of outer diameter micrometer (see 4.1.1);
--- Increased the type and description of the outer diameter micrometer reading device (see 4.1.2);
--- Modified the basic parameters of the outer diameter micrometer (see 4.2,.2004 version 4.2);
