Overview
EN ISO 13397-5:2015 (also published as ISO 13397-5:2015) is the international and European standard that defines the designs and dimensions for Jacquette scalers, a specific type of straight-bladed dental scaler used to remove supragingival and interproximal deposits. Published by CEN/ISO in 2015, this part of the ISO 13397 series complements the general requirements for periodontal curettes, dental scalers and excavators.
Key topics and technical requirements
- Scope: Specifies mandatory design features and dimensional limits for Jacquette scalers used in dentistry.
- Definitions: Includes precise terms such as Jacquette scaler, shank, functional shank and terminal shank (referencing ISO 1942 vocabulary).
- Design and dimensions:
- Type-specific dimensions are provided (Table 1) for instrument types J14–J38, covering blade width, blade thickness, blade length, and length to first bend.
- Angular parameters are specified: α (blade angle), β (offset angle), δ (terminal shank angle), φ (secondary shank angle) and θ (secondary shank offset angle), with measurement points defined in Table 2.
- Overall length requirement: all Jacquette scalers shall be ≤ 178 mm; single-side instruments specified at 150 mm.
- Measurement tolerances and points are defined to ensure consistent production and inspection (normative measurement method referenced to ISO 13397-1:1995, Annex A).
- Normative references: ISO 1942 and ISO 13397-1:1995 are required documents for terminology and general requirements.
- Conformity considerations: The standard includes symbols, measurement points and tolerances to support manufacturing, inspection and compliance.
Applications and users
EN ISO 13397-5:2015 is practical for:
- Dental instrument manufacturers designing and producing Jacquette scalers to meet internationally accepted dimensions and angles.
- Quality assurance and metrology teams performing dimensional inspection, calibration and acceptance testing.
- Procurement and regulatory bodies specifying compliant instruments for clinics, hospitals and public health programmes.
- Dental clinics and dental practitioners who require clarity on instrument types and expected geometry for clinical use and ergonomic handling.
- Testing laboratories and conformity assessors validating instruments against ISO/CEN requirements.
By standardizing blade geometry and shank configuration, EN ISO 13397-5:2015 helps ensure interchangeability, predictable clinical performance and reliable quality control of Jacquette scalers.
