Overview
EN ISO 22570:2020 (ISO 22570:2020) specifies requirements and test methods for spoons and bone curettes used in dentistry for oral surgical procedures. The standard defines shapes, dimensions, materials guidance, surface finish, hardness, marking/labeling and reprocessing performance to ensure safety, interchangeability and effective cleaning/sterilization of these hand‑guided dental instruments.
Key topics and technical requirements
- Scope: Applies to spoons (Hemingway design) and bone curettes (Lucas design) for removal of hard and soft tissue in jawbone regions.
- Classification: Four sizes - Type 1 (S), Type 2 (M), Type 3 (L), Type 4 (XL) based on working‑end width.
- Dimensions:
- Maximum overall length: 173 mm.
- Hemingway spoons: detailed breadth/length/height per type (e.g., widths 2.0, 2.5, 3.0, 3.5 mm) with tolerances (±0.15 mm for breadth; ±0.2 mm for length/height where applicable).
- Lucas curettes: specified widths with tolerances (±0.15 mm).
- Dimensional tolerances referenced to ISO 2768‑1 and GPS per ISO 1101.
- Materials: Manufacturer’s choice provided requirements are met; if stainless steel is used it shall conform to ISO 7153‑1 or ISO 21850‑1.
- Working end and hardness: Working ends are oval (Hemingway) or pear‑shaped (Lucas). Hardness requirement 42–58 HRC, tested per ISO 6508‑1 (Scale C) or Vickers (ISO 6507‑1) with conversion guidance.
- Surface finish: Working ends and shafts must be polished and free from defects/residues; handle surface should facilitate reprocessing.
- Reprocessing resistance: Instruments shall withstand 100 reprocessing cycles (cleaning, disinfection, sterilization) per manufacturer instructions and ISO 17664 without performance loss or corrosion (unless a lower number is declared by the manufacturer).
- Marking and information: Specifies on‑instrument marking, package labeling and instructions for use, consistent with medical device labeling standards.
Applications and users
This standard is intended for:
- Dental instrument manufacturers (design, production, materials selection, QC)
- Sterilization and reprocessing professionals (validation of cleaning/sterilization cycles)
- Regulatory and quality assurance teams ensuring compliance with medical device requirements
- Procurement specialists selecting standardized instruments for clinics and hospitals
EN ISO 22570 supports product consistency, safe reprocessing, and clear labeling-helpful for clinicians, dental surgery teams and device manufacturers.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
