ISO 21533:2018 specifies requirements and test methods for reprocessable cartridge syringes intended for intraligamentary injections. ISO 21533:2018 specifies requirements for cartridge syringes with ISO metric thread sizes, and only intended for intraligamentary injections. However, attention is drawn to the existence of a variety of syringes with imperial thread sizes (see Annex A).

Overview

EN ISO 21533:2018 (ISO 21533:2018) specifies requirements and test methods for reprocessable cartridge syringes intended for intraligamentary injections in dentistry. The standard applies to cartridge syringes with ISO metric thread sizes and covers design, dimensional requirements, performance tests and reprocessing resistance. It updates and supersedes the 2003 edition and adds a dosage-wheel design and clarification on reprocessing.

Key Topics and Requirements

Scope and design types

Applicable designs: pistol-grip, pen-grip, and dosage-wheel syringe configurations.
Only for intraligamentary injections (via the periodontal ligament).

Dimensional and interface requirements

Barrel dimensions, threaded needle‑mounting hub, and plunger rod dimensions and travel conform with ISO 9997.
Barrel must accept cartridges conforming to ISO 11499; if a viewing port is provided, the barrel must also accommodate a protective sleeve.

Performance and dosing

Volume delivered per lever depression or dosage‑wheel rotation must be within ±10% of the manufacturer’s claim (test methods outlined).

Protective sleeve

If supplied, the protective sleeve must be specified as single‑use or reprocessable and must retain integrity during use.

Resistance to reprocessing

Syringes must show no signs of corrosion after 100 reprocessing cycles when tested per the standard’s methods.

Testing and documentation

Test methods include visual inspection, volume measurement, protective sleeve dislodgement, and reprocessing resistance.
Requirements for instructions for use and product marking (syringe and unit pack) are included.

Additional note

Annex A highlights the existence of devices with imperial thread sizes (informative).

Applications and Users

Medical device manufacturers designing or producing reprocessable dental cartridge syringes for intraligamentary injections.

Regulatory and conformity assessors verifying compliance with European/CEN requirements.

Sterilization and reprocessing service providers evaluating device durability through repeated cycles.

Dental procurement and clinics specifying compliant syringes for practice and patient safety.

Design engineers implementing dosage‑wheel mechanisms or conversion between metric and imperial interfaces.
