YY/T 1604-2018Dentistry—Rotary polishers (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafted law to amend ISO 21671:2006 A1.2011 "Dental Rotary Polishing Instruments".

The main differences between this standard and ISO 21671:2006 A1.2011 are as follows.

--- With regard to the standard reference documents, this section made adjustments with technical differences to adapt to China's technical conditions and adjust the situation.

The focus is reflected in Chapter 2, "Normative References," and the specific adjustments are as follows.

- Use GB/T 9937 (all parts) instead of ISO 1942 (all parts), the degree of consistency between the two parts of the standard as follows.

- GB/T 9937.1-2008 Oral Vocabulary Part 1. Basic and Clinical Terms (ISO 1942-1:1989, IDT);

- GB/T 9937.2-2008 Oral Vocabulary Part 2. Oral Materials (ISO 1942-2:1989, IDT);

- GB/T 9937.3-2008 Oral Vocabulary Part 3. Oral Instruments (ISO 1942-3:1989, IDT);

- GB/T 9937.4-2005 Oral Vocabulary Part 4. Dental Equipment (ISO 1942-4:1989, IDT);

- GB/T 9937.5-2008 Oral Vocabulary Part 5. Terms related to testing (ISO 1942-5:1989, IDT).

--- As 4.3 has been detailed in the unit of size and angle, so delete the right in Figure 4, Figure 7, and Figure 8 in ISO 21671:2006 The expression "in millimeters" above.

--- Corrected some printing errors in ISO 21671:2006. The "c0.5" under the first line d3 of table 10 was changed to "±0.5". Table 20 The diameter d1 of the working part corresponding to the nominal diameter code and the nominal size 050 of the five rows is changed from "5.4" to "5.0". Table 23 The nominal diameter and nominal size of the second row were changed from "060" to "050".

--- As indicated in 4.3.2.1, "The rods of assembled polishing instruments should be Type 1, Type 2, Type 3 in YY/T 0967.1-2015.

Or type 4. ", so under section 10(c) "If applicable, the type of shaft conforming to ISO 1797" is amended to "If applicable, in line with "Shaft type of YY/T 0967.1-2015".

For ease of use, this standard has made the following editorial changes.

--- Some editorial changes were made in accordance with the requirements of GB/T 1.1;

--- Delete the preface and introduction of international standards;

--- For other international standards cited in this standard, if they have been converted into Chinese standards, this standard will replace the referenced international standard number with Corresponding national or industry standard number, and indicate the adoption relationship in Chapter 2 of this standard.

Introduction

This standard is one of the standards for dental rotary instruments.

The dimensions and other requirements of the polishing instruments specified in this standard shall ensure the interchangeability of these instruments in dental laboratories and dental clinics. Sexual and safe use is important.

The nominal diameters of the working parts listed in Chapters 5 and 6 are the same as those specified in YY/T 1011-2014.

It should be noted that a 15-digit digital coding system is given in YY/T 0873 "Digital Coding System for Dental Rotary Instruments". To divide all types of dental rotary instruments. Dental Rotary Polishing Instruments

1 Scope
