This part is part 3:

This section is drafted in accordance with the rules given in GB/T 1.1-2009:

This part is modified to adopt ISO 3630-3:1994 "Dental endodontic instruments - Part 3: Pressurizers, vertical pressers and lateral pressurizers Device": The main differences between this part and ISO 3630-3:1994 are as follows:

--- Regarding the normative reference documents, this standard has made adjustments with technical differences to adapt to my country's technical conditions and adjustments Centrally reflected in Chapter 2 "Normative References", the specific adjustments are as follows:

- Use YY 0803.1-2010 "Dental endodontic instruments Part 1: General requirements and test methods" (ISO 3630-1:

2008, IDT) to replace ISO 3630-1:1992 "Dental rotary instruments Part 1: Root canal files, expanders, barbed pulp extraction Needles, rasps, paste feeders, probes and cotton twists";

- Replace ISO 6360-1:1985 "Dental Digital coding system for rotating instruments - Part 1: General characteristics";

--- Split ISO 3630-3:1994 Figure 3 into Figure 3 and Figure 4;

--- The taper mark is represented by a percentage:

Introduction

YY 0803 covers the important features of hand-held endodontic instruments for root canal preparation:

In addition to special instruments, YY 0803.1 contains the general characteristics, requirements and test methods of all types of endodontic instruments:

It is worth noting that YY/T 0873 "Digital Coding System for Dental Rotary Instruments" provides a set of digital coding system, which stipulates 15 digits used to distinguish various types of dental rotary instruments:

Dentistry endodontic instruments part 3 : pressurizers

1 Scope

This part of YY 0803 specifies the requirements and test methods for vertical pressers and lateral pressers used for compacting root canal filling materials:

In addition to standard specifications, tapered specifications are also included: This type of tapered gauge is determined by the degree of taper that varies with the size of the instrument:
