Differences between the two specifications are expected but are technically insignificant to the function of the specified connections. Unfortunately this is impractical. He assumes that if it was correct on the previous product; then it must be still accurate for this new product. You can use gages specially designed for ISO As a suggestion to 59-1 making many drawing changes; a general Global Engineering Directive could be issued.

That ratification included a sunset provision that required review and re-ratification in to maintain validity.

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 I have seen this many times; and have even been guilty of the practice on occasion.

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.


Ignorance is fixable with a little education. This expectation is clearly stated in the ISO Forward.

There are two obsolete specifications related to Luer connectors: The intention is to iiso accurate information; regardless; errors may exist in the supplied information. The old specification number is copied to new products by ignorant people developing the new designs.

Gage Crib Worldwide, Inc. Sometimes the problem gets worse as the replacement specification becomes older. Inspecification ISO was published. This does not mean that gages are forbidden, or not useful, this just means that ISO does not define a gage.

People get persistent because: 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: ISO gages and reference connectors are identical to ISO gages and reference connectors with a couple of exceptions. Old Specifications Never Go Away. This page focuses on ISO This does not remove the fact that implementation of ISO should be done immediately.

Non-Interconnectivity Begins The big news of was that California legislated non-interconnectable couplings for patient side connections. How do we make our life easier when specification numbers change?

Here is isl sample text for this Global Engineering Directive: You have two choices: This was done a few years ago with implementation slated for The new Reference Connector has a longer 594–1 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. 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 This data is provided for general information only. Testing Procedures Immediately begin using test procedures according to those specified in ISO Here is some sample text for this Global Engineering Directive:.

In essence; this is mostly just a clerical change of the specification number. Because of that some product drawings, specifications and procedures reference specification numbers which are obsolete and which have been replaced by new numbers.

This document gives the directive as to how these obsolete numbers will be translated for compliance to the most current specification. The Luer Connection has had specification number changes over the years. Luer connections manufactured under either ISO or ISO are fully interchangeable and technically equivalent.

The medical industry, agreeing with California that it was a good idea, set about designing patient side connectors which are non-interconnectable. The person making this type of mistake just does not take the time to learn the correct information.
