VALIDATION / 03
Every result
comes with conditions.
A test is useful when it answers a defined design question. Part number, assembly state, load, environment and acceptance criteria make a result usable for selection and for the next design revision.
Start the test plan with the failure mechanism.
Initial continuity does not establish stability after exposure. A validation plan should identify the stress and the subsequent measurement: resistance after vibration, insulation after damp heat, and retention and electrical behaviour after mating endurance. Mating state and cable-end preparation also affect the scope of a result.

| Question | Method referenced in the presentation | Key records |
|---|---|---|
| Contact and insulation | IEC 60512-2-1 / IEC 60512-3-1 | Measurement points, test voltage, initial and post-exposure readings |
| Dielectric strength and temperature rise | IEC 60512-4-1 / IEC 60512-5-1 | Voltage and duration; current, wire size, ambient temperature and rise |
| Vibration and damp heat | IEC 60068-2-6 / -2-64 / -2-78 | Stress profile, duration, mounting and recovery conditions |
| Salt mist and water ingress | IEC 60068-2-11 / IEC 60529 | Media, exposure time, mating state, ingress inspection and electrical retest |
| Mating force and endurance | IEC 60512-13-1 / IEC 60512-9-1 | Force–displacement, cycles, load state and post-test checks |
| Materials and plating | ISO 3497 / ISO 527 / ISO 178 | Coating thickness, specimen condition, material lot and mechanical-test conditions |
These are methods listed in company material, not a claim that every model has completed every test. The applicable edition, severity and acceptance criteria belong in the project plan. Material screening and any required quantitative testing for RoHS or REACH also need distinct records.

Match a credential to its holder, product and date.
The presentation records high-tech-enterprise recognition in 2023 and an innovative-SME review in 2025. Management-system, connector and wire certificates are separate categories. Procurement review should match each document to its holder, models, standard and status rather than extend one certificate across all products.

| IATF 16949:2016 | 深圳利路通电子科技有限公司; connector design and production, and wire-harness production; NQA T14524 / IATF 0405699 | Historical certificate: 2021-06-18 to 2024-06-17. The displayed validity period has ended. |
| UL 2238 | Shenzhen Lilutong Connector Corp., Ltd.; cable assemblies for industrial control and signal distribution; 20190506-E481414 | Document dated 2019-05-06, page 1 of 3, without the complete model schedule; current status requires verification. |
| UL 62 | Shenzhen Lilutong Technology Industry Co Ltd; PVC-jacketed flexible cord; E521926 | Document dated 2021-07-13; a cord record, not a substitute for finished-connector certification. |

Request a review package for the actual part.
Provide the full part number, application, target market, current and voltage, cable specification and mounting arrangement. Engineering can then identify the drawing revision, pin definition, material requirements, applicable certificates and test records. Replacing an existing connector also requires the mating part and installation dimensions; similar appearance does not establish compatibility.
