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.

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, 549-1 about designing patient side connectors which are non-interconnectable. Unfortunately this is impractical.
The old specification number is copied to new products by ignorant 5994-1 developing the new designs. This page focuses on ISO The person making this type of mistake just does not take the time to learn the correct information. In essence; this is mostly just a clerical change of the specification number. Old Specifications Never Go Away.
ISO /1 and ISO /2 REPLACED BY ISO
Because of that some product drawings, specifications and procedures reference specification numbers which are obsolete and which have been replaced by new numbers. This data is provided for general information only. This document gives the directive as to how these obsolete numbers will be translated for compliance to the most current specification. If accuracy is critical, base your final decisions on the data provided in the root documents: Their effort resulted in a body of specifications under the umbrella of ISO This does not mean that gages are forbidden, or not useful, this just means that ISO does not define a gage.
Inspecification ISO was published.
Gage Crib Worldwide, Inc. He assumes that if it was correct on the previous product; then it must be still accurate for this new product. Sometimes the problem gets worse as the replacement specification becomes older.
Here is some sample text for this Global Engineering Directive: You can use gages specially designed for ISO 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: You have two choices: Top Gage Crib Worldwide, Inc.
The Luer Connection has had specification number changes over the years.
That ratification included a sunset provision that required review and re-ratification in to maintain validity. Differences between the two specifications are expected but are technically insignificant to the function of the specified connections. How do we make our life easier when specification numbers change?
Here is some sample text for this Global Engineering Directive:. This expectation is clearly stated in the ISO Forward. People get persistent because: There are two obsolete specifications related to Luer connectors: Live Chat Powered by jivochat.
This does not remove the fact that implementation of ISO should be done immediately. This was done a few years ago with implementation slated for Testing Procedures Immediately begin using test procedures according to those specified in ISO Luer connections manufactured under either ISO or ISO are fully interchangeable and technically equivalent.
ISO gages and reference connectors are identical to Sio gages and reference connectors with a couple of exceptions. I have seen this many times; and have even been guilty of the practice on occasion. The intention is to provide accurate information; regardless; errors may exist in the supplied information.
The new Reference Connector has a ido minimum length than the previous reference connector. The best move is to get militant about making the change; anytime the old specification number is referenced, change it.
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. As a suggestion to avoid making many drawing changes; a general Global Engineering Directive could be issued.
Ignorance is fixable with a little education. Non-Interconnectivity Begins The big news of was that California legislated non-interconnectable couplings for io side connections.
