Standard name: Conical fittings with a 6 % (Luer) taper for syringes, needles and certain other medical equipment - Part 2: Lock fittings (ISO 594-2:).

Applicable medical devices:

This standard applies to conical (Luer) fittings of small- bore connectors for use with hypodermic syringes and needles and covers components constructed from rigid and semi-rigid materials.

Testing capabilities to ISO 594-2 include:

  • Gauging test
  • Liquid leakage from the fitting assembly under pressure
  • Air leakage into the conical fitting assembly during aspiration
  • Separation force of fitting assembly
  • Unscrewing torque of fitting assembly
  • Ease of assembly
  • Resistance to overriding
  • Stress cracking.

Custom Testing

In many instances, testing requirements are beyond the test method parameters set out in a standard. Alongside our standard testing services, our expert team is able to develop a custom testing program to meet your specific testing requirements and resolve and design or functionality issues you might have.

Please note:  This standard has been withdrawn by the International Organization for Standardization and is revised by ISO 80369-7:2016. See also EN 1707:1996 “Conical fittings with a 6 % (Luer) taper for syringes, needles, and certain other medical equipment”, and BS 3930-2:1991 for guidance.
