AQL Inspection for Activewear: Levels, Defects and Acceptance Criteria
QUALITY CONTROL / LOT ACCEPTANCE
Agree the inspection rules before selecting the sample
For activewear AQL inspection, define the lot, choose a sampling standard and edition, agree the inspection level and defect classes, then apply the selected plan’s acceptance and rejection numbers. Check randomly selected garments against approved specifications. A passing sample supports a lot decision; it does not guarantee that every garment is defect-free.
1. What AQL does—and what it does not do
AQL means acceptance quality limit. It is a sampling-system parameter for evaluating a continuing series of lots, not permission to deliberately ship defective garments. An AQL of 2.5 does not mean that exactly 2.5% of each shipment may be defective, nor should an inspector calculate the acceptance count by multiplying the sample size by 2.5%. See the ASQ quality glossary for the formal terminology.
Keep three decisions separate: what makes a garment nonconforming, how many garments to inspect, and when the observed result accepts or rejects the lot. AQL alone answers none of these completely. A measurement tolerance, approved shade reference or seam requirement still has to come from the purchase specification.
The ISO catalogue lists ISO 2859-1:2026 as the current edition for AQL-indexed lot-by-lot attribute sampling. Another contractual choice is ANSI/ASQ Z1.4. Identify the agreed edition and use its complete procedures; do not combine a code-letter table from one source with acceptance numbers from another.
2. Separate inspection level, severity and AQL
| Parameter | Meaning for the inspection brief | Buyer decision |
|---|---|---|
| Inspection level | General levels I, II and III provide different sampling discrimination; special levels S-1 to S-4 use smaller samples with greater sampling risk. | Select the level for the stated inspection, using the selected standard. |
| Inspection severity | Normal, tightened and reduced are different inspection states. | Apply the scheme’s switching rules and retain lot history. |
| AQL by class | A selected parameter for each applicable defect category. | Agree values for the product and intended use. |
| Plan type | Single, double or multiple sampling has its own decision sequence. | Record the plan and follow every required stage. |
| Ac / Re | Acceptance and rejection numbers for the selected plan. | Copy and independently check the applicable table entry. |
General Level II is a common starting point for routine garment inspection discussions, but it is not a universal requirement. Level III is not the same as tightened inspection, and Level I is not the same as reduced inspection. A smaller sample for a costly or destructive test needs explicit agreement and cannot silently replace the main workmanship sample.
Treat major AQL 2.5 and minor AQL 4.0, if proposed in a quotation, as negotiable order parameters rather than mandatory activewear standards. Record the customer’s actual choice. For an isolated purchase, ask the inspection provider whether a scheme intended for a continuing series of lots is appropriate and what protection the chosen plan provides.
3. Define the lot and the unit before opening cartons
Write the purchase order, style, production batch, quantity, colorways and sizes included in the lot. Decide whether different styles or production runs require separate lots. Grouping unrelated production can obscure a problem in one subgroup; splitting a failed lot after seeing results can distort the original decision.
Define the inspection unit: one garment, a matched top-and-bottom set, or another specified unit. For sets, identify whether shade matching, component completeness and combined labeling are evaluated together. Also record whether the shipment is sufficiently complete and accessible for the planned inspection.
Use a documented random selection method across the accessible lot. Record carton IDs and unit IDs so each observation can be traced. Agree how colors and sizes are represented without letting staff hand-pick the best pieces. Extra checks on a suspect size or color are useful, but report targeted findings separately from the formal acceptance sample.
4. Build an activewear defect catalogue
The classifications below are proposed examples for buyer review, not automatic classifications imposed by a sampling standard. Severity depends on the actual effect, location, intended wearer and agreed specification. Attach annotated photographs of real approved and rejected examples when available.
| Proposed class | Activewear example | Evidence and decision boundary |
|---|---|---|
| Critical | A sharp needle fragment remaining in a garment. | Immediate containment and escalation under the agreed safety procedure; investigate affected production. |
| Major | An open crotch seam, broken functional zipper or failed waistband attachment. | Record the location and failure against the approved construction or function requirement. |
| Major | A key fit measurement outside the signed tolerance. | Record size, measurement point, method, nominal value and actual result. |
| Major, if specified | Opacity or support does not meet an agreed use test. | Use the defined conditions and acceptance criteria; avoid an improvised subjective test. |
| Minor, if agreed | A removable loose thread that does not impair seam integrity or appearance beyond the minor limit. | Distinguish an untrimmed tail from a broken or unraveling stitch. |
| Context-dependent | Uneven logo position, shade mismatch, labeling or packaging error. | Classify against the artwork, color reference, labeling requirement and commercial effect. |
For critical findings, agree an immediate hold and escalation rule rather than describing safety as “AQL 0.” Finding no critical defects in a sample does not prove none exist in the lot. Prevention, traceability and appropriate screening remain separate controls.
5. Count defective units and individual defects correctly
A garment can have several nonconformities. A plan based on percent nonconforming units and one based on nonconformities per hundred units do not use the same numerator. State the counting basis before inspection and retain both garment IDs and individual observations.
For example, garment G017 has an open seam and a misplaced logo, both classified as major by the approved catalogue. That is two major observations but one major-nonconforming garment when counting units within that class. Record any minor observation separately and apply the agreed cross-class counting rule; do not add all observations and call the total “defective garments.”
Do not reclassify a defect from major to minor merely because the major count is near rejection. If a classification is unclear, preserve the evidence, refer to the signed catalogue and obtain a documented technical decision. Keep the original observation in the report even when the interpretation changes.
6. Translate the plan into a release decision
Before inspection, enter the lot size, code letter, inspection state, sample size and class-specific Ac/Re values from the selected standard. Follow table arrows or instructions where applicable. The following example explains decision logic only; its numbers are hypothetical and are not an ISO or ANSI/ASQ table lookup.
| Hypothetical single-sample result | Pre-agreed rule | Outcome |
|---|---|---|
| 4 major-nonconforming units | Major Ac = 5; Re = 6 | Major category satisfies this example rule. |
| 6 major-nonconforming units | Major Ac = 5; Re = 6 | Major category rejects the lot. |
| 0 critical findings; 4 major units | Separate critical hold rule and major threshold | Still check minor results, required tests, quantities and documentation. |
Inspect the full required sample when making an acceptance decision. For a double or multiple sampling plan, an intermediate result may require another sample and cumulative counting; do not apply this single-sample example. Replacing defective sample pieces with good garments does not reset the count.
Record the category result and the overall shipment disposition separately. “Workmanship sample accepted” is more precise than “all quality approved” when laboratory results, assortment checks or required documents are outstanding. A lot rejected under the plan stays on hold until an authorized disposition is recorded.
7. Keep performance tests outside the workmanship shortcut
An appearance check cannot establish wash durability, stretch recovery, seam performance or colorfastness. Specify test methods, specimen selection, conditioning, cycles and acceptance limits in a separate test matrix. Link every report to the actual material, colorway or production lot it represents.
For leggings, discuss opacity under defined stretch and lighting; for sports bras, agree the relevant support and attachment checks; for running tops, specify the claimed moisture-management evidence. These are planning prompts, not universal tests or assumed Ohsure capabilities. A passing AQL workmanship result cannot substitute for a failed product requirement.
If only a subset receives measurements or functional tests, name that subset and its decision rule. Avoid saying that all sampled garments passed a test that was actually performed on just a few pieces. Preserve instrument identification, reference revisions and raw results where the method requires them.
8. Handle rejection without losing the evidence
Identify and segregate the affected lot. Record the defect types, photos, sample counts and original decision before repair begins. Agree whether the response is sorting, rework, replacement or another authorized disposition, and identify who owns the corrective action.
After sorting or rework, retain the quantity reconciliations and identification of the resubmitted goods. Arrange reinspection under the applicable procedure and agreed severity. Do not repeatedly draw fresh samples from an unchanged failed lot until one happens to pass. A concession, where permitted, should state its exact scope, quantity and approver instead of changing the original result.
Review recurring defects with production before the next shipment. For example, repeated waistband attachment failures should trigger investigation of the sewing operation and materials, not just extra final checks. Keep the inspection history needed to apply switching rules; reduced inspection is not a reward granted informally after one good report.
9. Prepare an Ohsure inspection brief
For an Ohsure order discussion, send the approved tech pack, sealed sample reference, size chart, color standards, artwork, packing instructions and proposed defect catalogue. Ask the team and inspection provider to confirm lot access, selection method, tests, reporting format and release authority for that specific order.
Request the completed plan and sample traceability alongside the final report. The downloadable checklist and defect log below are original blank working tools for this discussion. They are not certificates, actual Ohsure inspection results or proof of a verified factory inspection capability.
Frequently asked questions
Does AQL 2.5 allow 2.5% defective garments in my shipment?
No. It is a sampling parameter, not a fixed defective allowance for each shipment. Use the selected plan’s sample size and Ac/Re numbers.
Is General Level II compulsory for activewear?
No. Agree the level with the buyer and inspection provider for the selected procedure and risk. Record the rationale rather than copying a previous order automatically.
Can a lot pass if one major defect is found?
Possibly, depending on the selected acceptance number, counting basis and other requirements. One critical finding may trigger a separate immediate hold rule.
Does AQL inspection include fabric laboratory tests?
Only tests explicitly included in the agreed scope are covered. Workmanship sampling does not establish colorfastness, chemical compliance or long-term performance.
Should I count three defects on one garment as three defective units?
No. Keep each observation, but follow the defined counting basis. Under unit-based counting, one garment is counted once within a defect class even if it has several defects in that class.
What happens after a failed inspection?
Hold the identified lot, record the original result, agree corrective action and resubmit under the applicable procedure. Keep reinspection and any authorized concession traceable.
