Smithers Pira tests conical (Luer) fittings to ISO , assessing their characteristics and functional performance against the requirements set out in the . 15 Mar IS0 , published by Technical Committee 84 ‘Syringes for medical use and International Organization for Standardization (ISO). 17 Apr ISO /1 specifies the general requirements of conical fittings with a 6% (Luer) taper for syringes, needles and certain other medical equipment. ISO /2.

Ignorance is fixable with a little education. This expectation is clearly stated in the ISO Forward. Luer connections manufactured under either ISO or ISO are fully interchangeable and technically equivalent.
As a suggestion to avoid 549-1 many drawing changes; a general Global Engineering Directive could be issued. Inspecification ISO was published.
ISO /1 and ISO /2 REPLACED BY ISO
Live Chat Powered by jivochat. The medical industry, agreeing with California that it was a good idea, set about designing patient side connectors which are non-interconnectable.
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 Old Specifications Never Go Away. 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: Sometimes the problem gets worse as the replacement specification becomes older.
ISO gages and reference connectors izo identical to ISO gages and reference connectors with a couple of exceptions. Because of that some product drawings, specifications and procedures reference specification numbers which are obsolete and which have been replaced by new numbers. He assumes that if it was correct on the previous product; then it must be still accurate for this new product. This was done a few years ago with implementation slated for You can use ieo specially designed for ISO 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 uso possible ramifications.
This does not mean that gages are forbidden, or not useful, this just means that Ixo does not define a gage. There are two obsolete specifications related to Luer connectors: If accuracy is critical, base your final decisions on the data provided in the root documents: The Luer Connection has had specification number changes over the years. The old specification number is copied to new products by ignorant people developing the new designs.
How do we make our life easier when specification numbers change? You have two choices: This page focuses on ISO This data is provided for general information only. Here is some sample text for this Global Engineering Directive: The best move is to get militant about making the change; anytime the old ido number is referenced, change it.
Differences between the two specifications are expected but are technically insignificant to the function of the specified connections. Unfortunately this is impractical.
Non-Interconnectivity Begins The big news of was that California legislated non-interconnectable couplings for patient side connections. I have seen this many times; and have lso been guilty of the practice on occasion. The person making this type of mistake just does not take the time to learn the correct information. This does not remove the fact that implementation of ISO should be done immediately.
In essence; this is mostly just iiso clerical change of the specification number.
The intention is to provide accurate information; regardless; errors may exist in the supplied information. Top Gage Crib Worldwide, Inc. That ratification included a sunset provision that required review and re-ratification in to maintain validity. Their effort resulted in a body of specifications under the umbrella of ISO The new Reference Connector has a longer minimum length than the previous reference connector.
Testing Procedures Immediately begin using test procedures according to those specified in ISO
