Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 4032-1983 "has a balance spring oscillating system precision watch", compared with the GB/T 4032-1983,
The main technical changes in addition to editorial changes outside as follows.
--- Increase in Chapter 1, "scope";
--- Increase in Chapter 2, "Normative references";
--- Improve the "precision watch" is defined (see 3.1);
--- Delete provisions authorizing the publication "precision watch" title at CICC (International chronometer Management Committee) management.
This standard uses the translation method identical with ISO 3159.2009 "chronographs with spring balance oscillating system precision watch."
Correspondence between the consistency of the standards of international documents and normative references of the following documents.
--- GB/T 4028-1994 timing equipment inspection position marker (ISO 3158. 1976, IDT)
This standard made the following editorial changes.
--- In order to improve the relevance of standard content and title before Chapter 1, paragraph 1, the first sentence of "precision watch" supplementary pre-term
Attributive "has the balance spring oscillating system precision watch" (see Chapter 1); and added in front 3.1 "precision watch" definition
"Refers to a balance spring oscillating system" to define "precision watch" type (see 3.1);
--- Without changing the intent of the title, the name of the standard editorial simplified modification;
--- Increase form the table title (see Table 1, Table 2, Table 3);
--- In Chapter 6, "Test Procedure" 2 before the table to add a note in order to improve the operability of the test.
