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 .

Leakage; Separation from unscrewing; Stress cracking; and Non-interconnectable characteristics in the ISO ; Clause 6 specified tests.
ISO & 2 Separation Force and Unscrewing Torque Testing for Luer Tapers
ISO provides test methods for testing the separation force of Luer fitting assemblies and unscrewing torque of Luer fitting assemblies. Live Chat Powered by jivochat. How do we make our life easier when specification numbers change? I have seen this many times; and have even been guilty of the practice on occasion.
ISO /1 and ISO /2 REPLACED BY ISO
This expectation is clearly stated in the ISO Forward. This data is provided for general information only. Here is some sample text for this Global Engineering Directive:. The new Is Connector has a longer minimum length than the previous reference connector.
It is expected that all existing ISO connectors will be understood to meet the requirements of ISOand that when testing or validation occurs; it is made using the requirements of ISO 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 compressive force not greater than Live Chat Powered by jivochat. Keeping with the requirements of ISO ; the Reference Connectors we sell are from hardened stainless steel. ISO ; Page 3; Paragraph 4. He assumes that if it was correct on the previous product; then it must be still accurate for this new product.
In iwo, specification ISO was published.
They have 954-2 details which are not specified in ISO and which allow connection to test equipment. There are two obsolete specifications related to Luer connectors: The person making this type of mistake just does not take the time to learn the correct information.
Separation from axial load and Resistance to overriding in the ISO ; Clause 6 specified tests. ISO Fig C. You can use gages specially designed for ISO Non-Interconnectivity Begins The big news of was that California legislated non-interconnectable couplings for patient side connections.
Gage Crib Worldwide, Inc. Sometimes the problem gets worse as isl replacement specification becomes older. This document gives the directive as to how these obsolete numbers will be translated for compliance to the most current specification. This was essentially a clerical change so that the Needle and Syringe Luer Connectors could be included under the Small-Bore Connector collection of specifications: Gage Crib Worldwide, Inc. ISO ; Page 4; Paragraph 6.
ISO 594-1 & 2 Separation Force and Unscrewing Torque Testing for Luer Tapers
We are confident that we have what you are looking for. For testing of separation force lso unscrewing torque, take a look at ISO For testing of separation force without unscrewing torque, take a look at ISO Old Specifications Never Go Away. The Luer Connection has had specification number changes over the years.
Testing Procedures Immediately begin using test procedures according to those specified in ISO Luer connections sio under either ISO or ISO are fully interchangeable and technically equivalent.
Have a question about conducting the test for this standard? In essence; this is mostly just a clerical change of the specification number. Resistance To Separation From Unscrewing. This data is provided for general information only.
ISO is the standard specification and test method for the design of such Luer taper fittings. Top Gage Crib Worldwide, Inc. Separation force is tested by applying a tensile axial force from a fatigue test machine.
The intention is to provide accurate information; regardless; errors may exist in the supplied information. ISO Page 5; Paragraph 6. Since the connectors in ISO have already been developed you should seldom have to do this test to validate a connector to ISO The old specification number is copied to new products by ignorant people developing the new designs. As a suggestion to avoid making many drawing changes; a general Global Engineering Directive could be issued.
Ignorance is fixable with a little education.
ISO 594-2 F7 Luer Gage
ISO ; Page 5; Paragraph 6. The best move is to get militant about making the change; anytime the old specification jso is referenced, change it.
This does not remove the fact that implementation of ISO should be done immediately. ISO gages and reference connectors are identical to ISO gages and reference connectors with a couple of exceptions. If accuracy is critical, base your final decisions on the data provided in the root documents:
