foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces YY 1012-2004 "Dental Handpiece Coupling Dimensions", the main technical changes between this standard and YY 1012-2004
as follows.
--- Modified the scope (see Chapter 1, Chapter 1 of the.2004 edition);
--- Added normative references (see Chapter 2);
--- Added terms and definitions (see Chapter 3);
--- Added four types of "classification" (see Chapter 4);
--- Added general requirements (see 5.1);
---Added coupling system types. with and without light transmission, with internal and external air-water (spray) transmission, and improved and added technology
Drawings (see 5.2, Chapter 2 of the.2004 edition);
--- Increased the requirements for coupling force (see 5.3).
This standard uses the redrafting method to modify the use of ISO 3964.2016 "Dental handpiece coupling dimensions" (Dentistry-
as follows.
a) Regarding normative reference documents, this standard has made adjustments with technical differences to adapt to the technical conditions of our country and the circumstances of the adjustment.
