Use these calculators as working aids. Always follow the buyer-approved tech pack, inspection procedure and contractual AQL standard. AQL acceptance is not a target defect rate.
1. Measurement Sample Size (10%)
Calculate 10% measurement sample from total order/lot quantity.
Formula: lot quantity × sampling percentage. Buyer-specific measurement plans override this general calculation.
2. Measurement Pass / Fail
Compare actual measurement with spec and tolerance.
3. AQL Inspection Planner
Choose inspection level and lot size to get a common ANSI/ASQ Z1.4 / ISO 2859-1 General Inspection Level II sample-size reference, then review Ac/Re values.
The displayed Ac/Re values are a planning aid, not a certified reproduction of every single/double-sampling table or switching rule. Confirm exact code letter, normal/tightened/reduced status and buyer standard before pass/reject decisions.
4. DHU / Defects per 100 Units
Calculate defect rate for inline or final inspection.
5. First Pass Yield (FPY)
Percentage of pieces passing first inspection without repair.
6. Defect Pareto Summary
Enter defect counts to identify the biggest quality losses.
7. Fabric Shrinkage
Calculate length/width shrinkage after wash.
8. SPI / Stitch Density
Convert stitch count over measured length into SPI.
9. Inspection Result / Defect Log
Quick disposition helper for a checked lot.
Example limits only. Replace with Ac values from the approved inspection plan before use.
📏 Final Inspection Measurement Studio
The previous demo sheet has been replaced with the new FINAL MEASUREMENT SHEET workbook: three size ranges, the original POM specifications and tolerances, editable actual measurements, PASS/FAIL checks, audit, fit comments and print/export.
Open Final Inspection Measurement Studio10. Quality checklist — common checkpoints
Tick off checks during inline/final inspection. This checklist is not a substitute for buyer protocol.
11. Six S — Workplace Organization Audit
Score Sort, Set in Order, Shine, Standardize, Sustain and Safety. Rate each area 0–5.
12. 7 Wastes (TIMWOOD) Finder
Record waste observations by category and identify the biggest loss.
13. 8D Problem Solving
Build an 8D report: team, problem, containment, root cause, corrective action, validation, prevention and closure.
14. PDCA Improvement Cycle
Plan → Do → Check → Act. Record one controlled improvement cycle.
15. RCA — 5 Why Analysis
Trace a problem to a verified system cause. Avoid stopping at operator blame.
16. CAPA Action Tracker
Separate correction, corrective action and preventive action with ownership.
17. Six Sigma — DPMO & Sigma Practice
Estimate defects per million opportunities. Sigma level is an approximate conversion using the conventional 1.5σ shift.
18. Lean — Takt Time & Pitch
Calculate required production pace and container pitch.
19. Quality 7 Basic Tools Guide
Choose a tool based on the problem you need to understand.
20. Lean Quality Toolkit
Practical reference cards for daily factory improvement.
Small, continuous improvements led by the people doing the work.
Visual pull signal to control replenishment and WIP.
Error-proof fixtures, guides, sensors or checks to prevent mistakes.
Stop and respond when an abnormality is detected.
Go to the actual workplace, observe facts and ask why.
Document the safest known method, sequence and standard time.
Reduce changeover time by separating internal and external tasks.
Prioritize failure modes by severity, occurrence and detection.
