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 .

Unscrewing torque is tested by applying a 0. Here is some sample text for this Global Engineering Directive:.
isk 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 The medical industry, agreeing with California that it was a good idea, set about designing patient side connectors which are non-interconnectable.
This expectation is clearly stated in the ISO Forward. This does not remove the fact that implementation of ISO should be done immediately.
The intention is to provide accurate information; regardless; errors may exist in the supplied information. We are confident that we have what you are looking for. ISO Page 5; Paragraph 6.
ISO gages and reference connectors are identical to ISO gages and reference connectors with a couple of exceptions. The person making this type of mistake just does not take the time to learn the correct information. This data is provided for general information only. Resistance To Separation From Unscrewing.
This was done a kso years ago with implementation slated for 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: This page focuses on ISO Old Specifications Never Go Away. Separation force is tested by applying a tensile axial force from a fatigue test machine.
ISO is the standard specification and test method for the design of such Luer taper fittings. 594-22 are two obsolete specifications related to Luer connectors: If accuracy is critical, base your final decisions on the data provided in the root documents: Sometimes the problem gets worse as the replacement specification becomes older. ISO provides test methods for testing the separation force of Isp fitting assemblies.
Testing Procedures Immediately begin using test procedures according to those specified in ISO Top Gage Crib Worldwide, Inc. In essence; this is mostly just a clerical change of the specification number. Discussion on the change. That ratification included a sunset provision that required review and re-ratification in to maintain validity. These design details vary by manufacturer so be sure you understand the configuration before you order the Reference Connector. For testing of separation force and unscrewing torque, take a look at ISO Separation from axial load and Resistance to overriding in the ISO ; Clause 6 specified tests.
Inspecification ISO was published. Gage Crib Worldwide, Inc. Non-Interconnectivity Begins The big news of was that California legislated non-interconnectable couplings for patient side connections. The old specification number is copied to new products by ignorant people developing the new designs. Have a question about 5942- the test for this standard?
We offer machines, apparatus, lso, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
They have design details which are not specified in ISO and which allow connection to test equipment. As a suggestion to avoid making many drawing changes; a general Global Engineering Directive could be issued. Gage Crib Worldwide, Inc.
54-2 document gives the directive as to how these obsolete numbers will be translated for compliance to the most current specification.
For testing of separation force without unscrewing torque, take a look at ISO Live Chat Powered by jivochat. The old specification number is 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.
You can use gages specially designed for ISO Force ratings up to 2. 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.
Io accuracy is critical, base your final decisions on the data provided in the root documents: Keeping with the requirements of ISO ; the Reference Connectors we sell are from hardened stainless steel. ISO ; Page 5; Paragraph 6. This isi not mean that gages are forbidden, or not useful, this just means that ISO does not define a gage. Luer connections manufactured under either ISO or ISO are fully interchangeable and technically equivalent.
Unfortunately this is impractical.
