Legacy standard / transition hub

ISO 594 Luer Gauge and Connector Transition

Use this page when an older drawing, inspection plan or purchase request still says ISO 594, ISO 594-1 or ISO 594-2. The goal is to translate that legacy wording into the current Luer connector, gauge, reference connector, test method and RFQ path without treating different product roles as the same object.

What this page is for

ISO 594 is a translation problem, not a generic SEO page

Buyers still search legacy names because old drawings, device history files, inspection forms and procurement records do not all change at the same time. Chinatic should help an engineer decide whether the request is about a Luer gauge, an ISO 80369-7 reference connector, a test method setup or a complete test system.

Keep ISO 594-1 and ISO 594-2 visible for legacy drawing interpretation.
Route current Luer connector work to ISO 80369-7.
Separate gauge inspection from reference connector test setup selection.

Important distinction

Gauge does not automatically mean reference connector

A gauge is used for inspection. A reference connector is used as a mating connector in a test setup. Some buyers need both, but they should be selected and quoted as different product roles unless the approved KingPo product record explicitly combines them.

Legacy wording to current selection route

TermRoleHow Chinatic should handle it

ISO 594-1Legacy Luer cone topicUse when older drawings, inspection plans or purchase records refer to conical fittings and 6% Luer taper language.

ISO 594-2Legacy lock fitting topicUse when older records refer to lock fitting inspection, gauge wording or purchasing names that predate the current ISO 80369-7 route.

ISO 80369-7Current Luer connector selection pathUse for current Luer reference connector and gauge selection after the legacy wording has been translated into the current connector family and test context.

Gauge vs reference connector

Choose by product role before choosing the page

Legacy gauge wording

Often appears in older ISO 594 purchase records or inspection plans.

Translate the wording into the actual inspection need before selecting a modern product page.

Reference connector

A mating connector used in ISO 80369 test setup context.

Do not treat it as the same object as a dimensional gauge; choose by Figure, side and method.

6% Luer taper

A legacy and current search phrase buyers use when they are trying to identify Luer cone inspection scope.

Route the buyer to ISO 80369-7 gauge or reference connector selection, then confirm exact product evidence.

Related routes

Move from legacy standard names into usable engineering paths

A legacy ISO 594 inquiry normally resolves into one of three routes: dimensional gauge inspection, current ISO 80369-7 reference connector testing, or ISO 80369-20 method/equipment selection.

Lock or slip interface
Gauge inspection, reference connector testing or both
Required test method: leakage, axial load, unscrewing, overriding or stress cracking
