Technical overview

Medical Connector Test Tool Inspection and Calibration Support

Connector test equipment calibration is not limited to checking a single dimension. For medical connector test tools, the practical review may involve connector geometry, taper, thread profile, surface roughness, mating interface, force alignment, torque fixture condition and pressure-related measuring instruments.

KingPo can perform in-house dimensional inspection and condition review before delivery, repair, maintenance or third-party laboratory submission. When customers require an accredited certificate, KingPo can help coordinate submission to a qualified third-party metrology laboratory according to the required item and approved scope.

Standards covered

Calibration Support for ISO 80369, ISO 5356 and ISO 18250-3 Test Equipment

Different medical connector standards require different reference interfaces, gauges and functional fixtures. The final inspection method and certificate scope should be confirmed according to the purchased standard, the customer’s quality procedure and the selected laboratory’s approved calibration scope.

Service workflow

Calibration and Submission Workflow

Each project starts with a technical review. This avoids sending the wrong tool to the wrong laboratory and helps customers choose between in-house inspection, repair, replacement or third-party accredited calibration submission.

Submit DetailsSend standard, equipment list, drawing and certificate requirement.

Technical ReviewKingPo checks tool type, condition and applicable method.

In-House CheckDimensional and condition review is performed where needed.

Repair AdviceRepair or replacement is confirmed before certificate submission.

Lab SubmissionTools are submitted to a qualified third-party laboratory if required.

Certificate ReturnCertificate, report or inspection record is returned for review.

Next IntervalKingPo helps explain results and future review recommendations.

Third-party laboratory support

Accredited Certificate Submission Support

For customers requiring third-party accredited certificates, KingPo can assist with submission to qualified metrology laboratories. The final certificate issuer, accreditation mark, measurement item and uncertainty statement are determined by the selected laboratory and its approved scope.

Connector Test Equipment Calibration — Third-Party Accreditation Marks

Example cover page of a third-party test report issued by the Guangdong Institute of Metrology. Depending on the requested project and the laboratory’s approved scope, the final document may be issued as a test report or calibration certificate.

KingPo does not claim that all calibration activities are performed under KingPo-owned CNAS or ILAC accreditation unless specifically stated on the issued certificate.

Quotation preparation

Information Required for Calibration Quotation

Providing complete information helps avoid incorrect certificate scope, wrong measurement items or delays caused by missing drawings and serial-number details.

Use this table to prepare connector test equipment calibration quotation information before submitting gauges, reference connectors or fixtures for inspection or third-party laboratory review.
Information	Example	Why It Matters
Equipment type	ISO 80369-7 Luer gauge set, ISO 5356 conical connector gauge, ISO 18250-3 enteral connector fixture	Determines whether the item can be inspected in-house or submitted for accredited calibration.
Standard and edition	ISO 80369-7:2021, ISO 5356-1:2015, ISO 18250-3:2018	Different editions may require different figures, methods or acceptance criteria.
Figure / Annex / clause	Figure C.1–C.6, connector type, leakage method, torque method	Prevents mismatching the tool with the wrong reference interface or test method.
Certificate requirement	In-house inspection record or third-party accredited calibration certificate	Defines laboratory selection, cost, lead time and report format.
Condition and history	New, used, damaged, after repair, out of calibration	Helps identify whether cleaning, repair or replacement should be considered first.

Frequently asked questions

Connector Test Equipment Calibration FAQ

Can KingPo provide CNAS or ILAC-recognized calibration certificates?

KingPo can coordinate submission to qualified third-party metrology laboratories when an accredited certificate is required. The final certificate issuer, accreditation mark and calibration scope depend on the selected laboratory’s approved scope.

Is in-house inspection the same as accredited calibration?

No. In-house inspection helps verify dimensional condition, tool condition and manufacturing quality. Accredited calibration is performed and certified by an accredited laboratory within its approved scope.

Which ISO 80369 equipment can be reviewed?

Typical items include ISO 80369-7 Luer gauges and reference connectors, ISO 80369-3 enteral connector references, ISO 80369-6 neural application references, leakage fixtures, force fixtures and torque fixtures. Feasibility should be confirmed according to the exact figure, drawing and certificate requirement.

Can used gauges be repaired before calibration?

KingPo can inspect wear, surface condition and dimensional deviation. If repair or replacement is more appropriate than calibration, KingPo will advise before third-party laboratory submission.

How often should medical connector gauges be calibrated?

The interval depends on the user’s quality system, usage frequency, wear risk, regulatory requirements and customer audit expectations. Many laboratories define an annual or project-based review cycle, but the final interval should follow the user’s internal procedure.

Need calibration support for ISO 80369 gauges or reference connectors?

For ISO 80369, ISO 5356 and ISO 18250-3 connector test equipment, KingPo can support gauge inspection, reference connector review, calibration submission coordination and replacement tool selection when needed. If the tool is worn, damaged or unsuitable for the required method, review the ISO 80369 Testing Equipment page before requesting a certificate.
