Overview
EN ISO 6360-2:2004/A1:2011 (ISO 6360-2:2004/Amd 1:2011) is a CEN-endorsed amendment to the international standard that defines the number coding system for rotary dental instruments - Part 2: Shapes. This Amendment 1 (approved December 2011) updates the shape and design tables used to assign numeric codes and multilingual designations to rotary instrument geometries (e.g., wheels, discs, cylindrical and conical shapes, trephines). The document is published in English, French and German and was required to be adopted by CEN members as a national standard by mid-2012.
Key topics and technical content
- Number coding system for shapes: Amendment 1 extends Table 1 (general shapes and design), Table 2 (discs) and Table 3 (special instruments) with new numeric codes and multilingual designations (EN/FR/DE).
- New entries: Examples added include codes for round long-neck shapes (004), inverted conical forms (017), wheel/disc variants (065, 067–071, 326, 353, 383, 387, 388, 394–396), and numerous special-instrument codes (e.g., twist drill 428, trephines 554–558, depth marker 560).
- Dimensional and feature references: Some entries reference length ranges and features (for example, several wheel and cylindrical entries include l ranges such as 3.5 mm ≤ l
