Quality Control

Incoming Inspection (IQC)

AQL-based incoming quality control for raw materials and components. Catch defects before they enter production, track supplier quality, and maintain ISO 9001 compliance.

IQC (Incoming Quality Control) / receiving inspection is the process of checking raw materials and components before they enter production. NS-eIQC digitises sampling, defects, and supplier trends so problems don't become escapes.

Quality Starts at Goods-In

The cheapest defect is the one you never let into production. NS-eIQC provides structured incoming inspection using AQL sampling plans, ensuring consistent quality control and supplier accountability.

  • AQL-based sampling plans for statistical confidence
  • Customisable inspection checklists per part
  • Photo attachments for defect documentation
  • Supplier performance tracking and scorecards
  • eIQC Yield dashboards and trending

Built-in AQL tables determine sample sizes automatically. Normal, tightened, and reduced inspection levels.

Inspection Checklists

Create custom checklists per part number. Dimensional, visual, and functional checks.

Photo Documentation

Attach photos of defects directly to inspection records. Visual evidence for supplier discussions.

eIQC Yield Dashboard

Visual charts showing incoming quality trends by supplier, part, and time period.

Supplier Scorecards

Track supplier quality performance over time. Generate reports for supplier reviews.

Export & Reporting

Export to Excel, CSV, and PDF. Generate inspection reports for management review.

Statistical Quality Control

What is AQL?

Acceptance Quality Limit (AQL) is the maximum percentage of defective units that can be considered acceptable when sampling a batch. NS-eIQC uses international AQL tables (ISO 2859 / AS 1199) to determine the right sample size for your lot.

By using statistical sampling, you get confidence in your quality decisions without inspecting every single item - saving time while maintaining standards.

Normal Inspection

Standard sampling level for ongoing production. Switch from normal when supplier quality changes.

Tightened Inspection

Increased sampling when quality deteriorates. More stringent accept/reject criteria.

Reduced Inspection

Smaller samples for proven suppliers with excellent track records. Saves inspection time.

Industry Standards Support

ISO 9001

Clause 8.6 - Release of products and services. Document inspection results for compliance.

ISO 13485

Medical device incoming inspection requirements with documented evidence.

AS9100

Aerospace quality management with receiving inspection documentation.

Catch Defects Before Production

The cost of catching a defect at goods-in is a fraction of finding it during production or at customer delivery.

FAQ: Incoming Quality Control (AQL Sampling)

What is incoming quality control (IQC)?

Incoming Quality Control (IQC) is the inspection and verification of raw materials/components at goods-in, before they’re accepted into stock or production. The goal is to stop defects early and create traceable evidence for suppliers and compliance.

What does AQL mean in incoming inspection?

AQL (Acceptance Quality Limit) is a statistical sampling method that defines how many units to inspect from a lot and the accept/reject criteria. It gives confidence without checking every item.

How does AQL sampling reduce inspection time?

Instead of 100% inspection, AQL uses sample sizes based on lot size and inspection level (normal/tightened/reduced). You inspect fewer parts while still controlling risk and documenting the decision.

Can we customise checklists per part number or supplier?

Yes—good IQC systems let you create inspection checklists per part number (dimensions, visual, functional), and vary requirements by supplier, category, or risk level.

How do you track supplier quality performance over time?

By recording defects per lot, attaching photo evidence, and reporting yield/defect trends by supplier and part number. This supports supplier reviews, corrective actions, and objective scorecards.

Does IQC support ISO 9001 / ISO 13485 / AS9100 compliance?

Yes. Incoming inspection records and evidence support requirements around product release and traceability (e.g., ISO 9001 clause 8.6), and similar expectations in ISO 13485 and AS9100 environments.
