17 Apr Scope: ISO specifies requirements for conical lock fitting with a 6% (Luer) taper for use with hypodermic syringes and needles and with certain other. 12 Jun ISO was replaced with ISO so that the Needle and Syringe Luer Connectors could be included under the Small-Bore Connector. Smithers Pira tests conical (Luer) fittings to ISO , assessing their characteristics and functional performance against the requirements set out in the .

The best move is to get militant about making the change; anytime the old specification number is referenced, change it.
This data is provided for general information only. Leakage; Separation from unscrewing; Stress cracking; and Non-interconnectable characteristics in the ISO ; Clause 6 specified tests. ISO provides test methods for testing the separation force of Luer fitting assemblies and unscrewing torque of Luer fitting assemblies.
The intention is to provide accurate information; regardless; errors may exist in the supplied information. Here is some sample text for this Global Engineering Directive: Live Chat Powered by jivochat.
ISO & 2 Separation Force and Unscrewing Torque Testing for Luer Tapers
Force ratings up to 2. Inspecification ISO was published.
Top Gage Crib Worldwide, Inc. The person making this 594- of mistake just does not take the time to learn the correct information. ISO is the standard specification and test method for the design of such Luer taper fittings. Their effort resulted in a body of specifications under the umbrella of ISO He assumes that if it was correct on the previous product; iao it must be still accurate for this new product.
Unfortunately this is impractical. This document gives the directive as to how these obsolete numbers will be translated for compliance to the most current specification.
Have a question about conducting the test for this standard? The old specification number 594–2 called-out on drawings which stay in production for many years past when the specification was replaced; the drawing is not revised because of cost and other possible ramifications.
Gage Crib Worldwide, Inc. Unscrewing torque is tested by applying a 0. The old specification number is copied to new products by ignorant people developing the new designs. Live Chat Powered by jivochat.
Sub-Atmospheric Pressure Air Leakage 6. For all tests in ISO requiring an assembled Luer fitting, fittings are assembled using an axial torsion machine, applying a oso force not greater than ISO Page 5; Paragraph 6.
ISO 594-1 & 2 Separation Force and Unscrewing Torque Testing for Luer Tapers
Sometimes the problem gets worse as the replacement specification becomes older. Give our test engineers a call today for help configuring the best test machine 954-2 accessories according to your standard. Because of that some product drawings, specifications and procedures reference specification numbers which are obsolete and which have been replaced by new numbers.
Old Specifications Never Go Away. These design details vary by manufacturer so iao sure you understand the configuration before you order the Reference Connector. Separation force is tested by applying a tensile axial force from a fatigue test machine. The new Reference Connector has a longer minimum length than the previous reference connector. Resistance To Separation From Unscrewing.
ISO ; Page 4; Paragraph 6.
We are confident that we have what you are looking for. By ixo of our testing expertise and modular product design, we will help find the solution that is right for you.
ISO /1 and ISO /2 REPLACED BY ISO
The Luer Connection has had specification number changes over the years. Differences between the two specifications are expected but are technically insignificant to the function of the specified connections. The Luer taper is a standardized system of small-scale fluid fittings for making leak-free connections between sections on medical and laboratory instruments, including hypodermic syringe tips, catheters and infusion devices.
ISO gages and reference connectors are identical to ISO gages and reference connectors with a couple of exceptions. For testing of separation force and unscrewing torque, take a look at ISO Ignorance is fixable with a little education.
