IQC
Incoming materials
Review the identity and relevant dimensions or material characteristics of incoming components.
MANUFACTURING & QUALITY
Look beyond the product photograph.
For distribution programs and OEM builds, quality review starts with the approved specification, the inspection scope and the evidence that applies to the actual product ordered.
PRODUCTION CONTEXT
See where products are assembled.
A workshop image is a starting point, not a substitute for product-specific evidence. Review the assembly configuration, identification and inspection requirements relevant to your order.

Follow the inspection stages
Use the stage sequence to align incoming checks, in-process control, finished-product verification and outgoing review with your order requirements.
IPQC
In-process checks
Check the assembly against the approved configuration during production.
FQC
Finished-product checks
Review applicable functional and electrical checks for the completed product.
OQC
Outgoing review
Confirm the agreed outgoing inspection, identification and packaging requirements.
TESTING CONTEXT
Match the evidence
to the application.
Electrical endurance, temperature rise and environmental performance concern different risks. Request the test method, conditions and tested configuration, rather than relying on a test name alone.
Do not assume every model carries the same rating, ingress protection or approval. Product-level claims need product-level evidence.
| Buying Decision | Evidence to Request | What to Verify |
|---|---|---|
| Electrical suitability | Product rating and relevant test information | AC / DC, load type, current duration and test conditions |
| Mechanical integration | Dimensional drawing and approved sample | Cutout, mounting, terminals and clearance |
| Environmental suitability | Applicable environmental or ingress-protection report | Model, assembly state, seals and installation conditions |
| Repeat-order consistency | Approved specification and agreed inspection record | Configuration revision, labeling and acceptance criteria |
