ISO 594/1 describes dimensions, testing profile, and parameters for testing conical fittings with a 6% (luer) taper for hypodermic syringes, needles, and certain other medical equipment, such as transfusion and infusion sets. This standard covers rigid and semi-rigid materials for gauging and performance.

Several mechanical tests in section 5, figures 4+5 require torque testing.

Section 5.2

First, according to figures 4 + 5, connect fitting to steel male or female reference fitting.

Assemble components by applying an axial force of 27.5 Newtons (6.18 lbf) for 5 seconds while applying a torsional force < or = 0.1Nm (.88 lb-in) and < or = to 90 degrees.

Introduce water

Expel Air

Check to determine if outside of fitting is dry

Seal the outlet - bring internal pressure to 300kPa.

Maintain pressure 30 seconds.

**Highlights on the Torsion Requirements for Section 5.3.1.1 and 5.5.1.

* Apply axial force of 25N for 5 seconds simultaneously applying 0.1Nm to an end limit of 90 degrees. Full description of ISO 594/1-1986 is necessary to complete this test.
