Overview - ISO 11499:2014 (Dentistry - Single-use cartridges for local anaesthetics)
ISO 11499:2014 specifies performance, testing and labelling requirements for single‑use dental cartridges (1.0 ml, 1.7 ml, 1.8 ml and 2.2 ml nominal capacity) used with dental cartridge syringes. The standard ensures cartridges reliably deliver local anaesthetics by defining tests for leakage, plunger movement, extractable volume, air‑bubble control, dimensional limits and labelling. It supports compatibility with cartridge syringes complying with ISO 9997 and ISO 21533 and recommends biocompatibility assessment with ISO 10993-1/ISO 7405.
Key topics and technical requirements
- Nominal capacities covered: 1.0 ml, 1.7 ml, 1.8 ml, 2.2 ml.
- Leakage: Cartridges must be free from leakage. Test applies a 30 N axial force to the plunger for 1 minute and inspects for failure.
- Plunger movement (force requirements):
- Force to initiate movement ≤ 30 N.
- Force to sustain movement throughout effective length: 2 N ≤ F ≤ 20 N.
- Extractable volume: Measured by emptying cartridge into a graduated container (or gravimetrically); extractable volume must be at least the stated nominal volume.
- Air bubble control: Air bubble must not be visible below the rim of the metal cap when cartridge is held vertically and tapped.
- Dimensions:
- Max overall lengths: 1.0 ml = 44.0 mm; 1.7/1.8 ml = 65.0 mm; 2.2 ml = 77.5 mm.
- Max overall diameter (including label): 9.0 mm.
- Colour coding (optional): If used, two indelible bands indicate anaesthetic agent/concentration and vasoconstrictor/concentration with specified positions, widths and Pantone color guidance.
- Sampling and test conditions: Sample size 10 cartridges per batch; tests at (20 ± 5) °C.
- Marking and labelling: Primary and secondary container labelling requirements include manufacturer, extractable volume, active ingredients/concentrations, lot number, expiry date, storage recommendations and latex warnings.
Practical applications - who uses ISO 11499:2014
- Manufacturers of dental cartridges and components - for product design, quality control and regulatory compliance.
- Testing laboratories and quality assurance teams - to perform standardized leakage, force and extractable volume tests.
- Regulatory bodies and notified bodies - to evaluate conformity for market approval.
- Dental clinics and procurement specialists - to select compatible, safe single‑use cartridges for cartridge syringes.
- R&D and product engineers - for designing cartridges that meet dimensional and functional performance criteria.
