What are AQL 1.5 and AQL 2.5 in sportswear quality control?

Update Time:2026/10/27

AQL 1.5 and AQL 2.5 are Acceptance Quality Limit values used within an agreed acceptance-sampling scheme. Under otherwise equivalent sampling conditions, a lower AQL generally sets stricter acceptance criteria. Neither value is a simple allowance for that percentage of defects in an inspected sample or shipment.

What belongs in the inspection plan?

  • Sampling standard and edition, lot definition, and lot size
  • Inspection level, sampling plan, and inspection severity where applicable
  • Sample-selection method and coverage across styles, colors, and sizes
  • Agreed defect classes and the AQL values applied to each relevant class
  • Sample size and the applicable acceptance and rejection numbers
  • Approved product references, measurement methods and tolerances, report records, and corrective-action requirements

AQL is not the inspection level. The sample size and acceptance limits must come from the applicable plan, not from multiplying the order or sample quantity by 1.5% or 2.5%.

Critical safety or regulatory risks need an explicit acceptance policy and appropriate preventive, detection, or compliance controls. A zero-acceptance rule for a checked sample is not proof that no hazard exists anywhere in the lot.

Does passing an AQL inspection mean every garment is defect-free?

No. Passing means the lot met the agreed sampling acceptance criteria for the checks performed. Garments outside the selected sample are not individually inspected under that sampling plan, and undetected defects may remain.

Defects found during inspection should still be documented and handled under the agreed corrective-action requirements. A passing lot result does not make a known nonconforming garment acceptable.

How sampling and full visual screening work together

At Call The STYLE, an agreed AQL inspection, such as AQL 1.5 or AQL 2.5 where appropriate, can be combined with 100% visual and workmanship screening of finished garments. Confirm the actual checks and records for the specific order.

Here, 100% refers to the garments checked for the defined screening scope. It does not mean that every POM or every functional property is tested on every garment. Laboratory, destructive, and specialized performance tests normally use selected samples under a separate test plan.

Neither sampling nor full visual screening guarantees zero defects. Agree the inspection and quality-control requirements before production, and review the report’s scope, findings, and corrective actions rather than relying only on the word “PASS.”
