ISO 6360-1:2004

Overview

ISO 6360-1:2004 - Dentistry - Number coding system for rotary instruments - Part 1: General characteristics defines a standardized number coding system for dental rotary instruments and accessories. The standard establishes a 15‑digit identification number that encodes general characteristics such as the material of the working part, coating or binding, shank/handle type, and overall length. Optional additional digits (16–18) are available for diamond instruments. ISO 6360-1:2004 is intended for manufacturers, suppliers and the dental profession to enable consistent cataloguing, procurement and international communication about rotary instruments.

Key Topics

• 15‑digit overall number: The core of the system. If information is not required, the digit “0” is used as a placeholder.
• First group (digits 1–3):
  • Digits 1–2: material of the working part or diamond grit size (ranges shown 01–88).
  • Digit 3: coating for burs/cutters or binding for diamond/abrasive instruments (0–9, with defined ranges).
  • Examples from the standard: tungsten carbide (50), high‑speed steel (35), titanium (48), nickel‑titanium (49), electrocorundum/corundum (61–63) and diamond codes (80, 82–88) for various grit sizes.
• Second group (digits 4–6):
  • Digits 4–5: shank or handle type (also covers bore diameters for unmounted instruments).
  • Digit 6: overall length code.
• Optional digits (16–18): provisional three digits for extra diamond characteristics (reviewed after five years).
• Generic coding: The codes are generic identifiers; precise product specifications require reference to the applicable product standard.
• Normative references: ISO 1797‑1 and ISO 1797‑2 (shanks).

Applications

ISO 6360-1:2004 is practical for:

• Manufacturers and product designers: assigning standardized identification numbers for rotary instruments and accessories.
• Cataloguing and e‑commerce: consistent product listings across markets and languages.
• Procurement and inventory management: unambiguous ordering, stocking and traceability.
• Regulators and testing bodies: classification and cross-reference of instruments during conformity assessment.
• Dental professionals and trade: clear communication about instrument materials, coatings and geometric grouping.

The standard recommends consulting ISO 6360-2 (shapes) and the subsequent parts (ISO 6360-3 to ISO 6360-7) for shape and specific characteristic codes when creating a complete identification number.

Related Standards

• ISO 6360 series: Part 2 (Shapes); Part 3 (Burs and cutters); Part 4 (Diamond instruments); Part 6 (Abrasive instruments); Part 7 (Mandrels). Part 5 (root‑canal instruments) was under preparation in the 2004 edition.
• ISO 1797-1, ISO 1797-2: dental rotary instrument shanks.

For allocation of new numbers, applicants are advised to contact the ISO/TC 106/SC 4 secretariat (DIN NADENT) which maintains the master records for assigned numbers.
