Small-bore connector standards, products and test methods in one selection path
Chinatic now treats ISO 80369, IEC 80369-5 and ISO 18250 as a structured domain model for buyers who need reference connectors, gauges, fixtures, ISO 80369-20 equipment, complete systems or calibration support.

Use the same chain engineers, buyers and QA teams need for quotation
Every public page should help the visitor move one step closer to a reviewed item, method, fixture, equipment channel or document route.

Choose by the item or service the buyer is trying to source
Match a sample connector to the figure-defined reference interface needed for functional testing.
standard part / figure or annex / male or female / slip or lock / rigid or semi-rigid / certificate expectation
Gauges and Gauge SetsInspect Luer dimensional or fit conditions without confusing gauges with reference connectors.
checked sample side / ring or plug / lock or slip / individual gauge or set / certificate wording
ISO 80369-20 Test EquipmentSelect the instrument path by measured action: leakage, force, torque, overriding or stress cracking.
method annex / pressure or force or torque channel / fixture / sample side / report requirement
Fixtures and Assembly DevicesHold, align or assemble the connector pair so the chosen method can be repeated.
sample geometry / mating counterpart / axial or side load / torque interface / method annex
Complete Test SystemsQuote multiple items as one reviewed setup when the buyer needs method coverage rather than a single part.
standard part / method group / reference connectors / fixtures / equipment / calibration route
Calibration and RecertificationChoose the right verification or certificate route for gauges, reference connectors and instrument channels.
item type / measured feature / traceability wording / third-party accredited lab option / recertification interval
Use the standard part to narrow application, connector and method context
Respiratory applications
Confirm R1/R2 context, connector side and ISO 80369-20 method before product selection.
ISO 80369-3Enteral applications
Start with enteral connector side, then select reference connector and ISO 80369-20 method.
IEC 80369-5Limb cuff inflation applications
Confirm cuff inflation connector role, applicable corrigenda, method and fixture needs.
ISO 80369-6Neural applications
Confirm neural application, sample connector side and selected ISO 80369-20 method.
ISO 80369-7Intravascular or hypodermic applications
Choose reference connector, gauge, fixture or ISO 80369-20 equipment by sample side and method.
ISO 80369-20Common test methods
Choose the measured action, then select equipment, fixture, reference connector and calibration route.
