Four Tests That Decide Whether A Harness Ships

A harness that looks right can still be wired wrong, and a crimp that looks right can still pull out. These are the checks that separate the two.

01

Continuity And Circuit Verification

Verifies the physical arrangement sequence of the harness terminals and the circuit topology between them

02

Circuit Configuration Verification

Confirms that a complete, uninterrupted current flow path exists within each circuit

03

Terminal Retention Strength Test

Measures the mechanical reliability of the connection between the terminal and the wire

04

Ingress Protection Rating Test

Evaluates the dust and water resistance sealing performance of harness connectors

Before Production Starts

  • The circuit table is read back from your drawing or sample and confirmed in writing
  • Connector part numbers are fixed, with equivalents proposed only where a part is obsolete
  • Sample orders ship within 3 days of confirmation so you can fit the part yourself
  • Samples are confirmed prior to trial or mass production

During And After Production

  • Terminal arrangement and circuit topology verified against the approved map
  • Crimp retention checked by pull off force, not by appearance
  • Sealing performance tested where the assembly is rated for dust and water
  • Products individually packed in PE bags and boxed to the specified quantity

Quality Questions

Which tests do you run on a harness?

Continuity and circuit verification, circuit configuration verification, terminal retention strength testing and ingress protection rating testing, applied according to the harness type.

What does terminal retention testing prove?

It measures the mechanical reliability of the connection between the terminal and the wire. Crimp quality is invisible once a terminal is inside a housing, so pull off force is the only honest measure of it.

Is the company certified?

Yes. Certified to IATF 16949 and UL standards.

How do you keep repeat orders identical?

Samples are confirmed prior to trial or mass production, and the approved sample becomes the reference for every repeat build.
