Introduction

YY/T 1021 aims to establish basic requirements, marking methods and design criteria that are generally applicable to dental extraction forceps products, and consists of three parts.

---Part 1: General requirements, the purpose is to clarify the general requirements and test methods such as material properties and mechanical properties of dental extraction forceps.

---Part 2: Labeling, the purpose is to clarify the labeling rules and labeling methods of dental extraction forceps.

---Part 3: Design, the purpose is to clarify the classification and design specifications of dental extraction forceps.

Dental extraction forceps are used to remove teeth. Most tooth extraction forceps can be used on both jaws and on more than one type of tooth, for example, on the front of the maxilla or mandible.
