What is ISO 594 1?

ISO 594/1 specifies the general requirements of conical fittings with a 6% (Luer) taper for syringes, needles and certain other medical equipment.

What is ISO 594?

ISO 594 is a testing standard that defines and measures the general requirements for 6% taper conical fittings. The requirements tested in this method include gauging, liquid and air leakage, separation force, unscrewing torque, ease of assembly, resistance to overriding, and stress cracking.

Is ISO 594 obsolete?

ISO 594 is replaced with ISO 80369-7. ISO 594 was replaced with ISO 80369-7 in 2016. The old numbers: ISO 594/1 and ISO 594/2; have been replaced with: ISO80369-7.

What is the difference between ISO 594 and ISO 80369?

Unlike ISO 594-2, the new standard adds a flexural modulus of 700 MPa or higher – any softer material cannot be used for compliance to this standard. ISO 80369-7 also states that by using modern test equipment and methods, it is now practical to define the dimensions with greater precision.

How do you remove a Luer lock syringe?

Grasp the base of the needle, not the safety sheath, and push on the syringe while turning clockwise to make sure the needle is securely attached to the syringe. Move the needle safety sleeve away from the syringe body before removing the needle cap. Remove the needle cap.

What is 6% luer taper?

What exactly is a luer? A luer is a standardized connection type based on a conical taper design. This taper is 6% or 1.72 degrees from the centerline. This taper is often referred to as the luer taper.

Are luer locks universal?

Luer Lock is an industry standard tapered termination utilized by most syringe manufacturers including medical Hypodermic syringes. Luer Lock needles are common because their design is controlled by a series of universal standards which guarantees compatibility between manufacturers.
