TS 2756-1/T1

TS 2756-1/T1 is the Turkish edition of a standard on sampling procedures for inspection by attributes, specifically the use of sampling plans indexed by Acceptable Quality Level (AQL) for lot-by-lot inspection. In practical quality control, this means evaluating a production lot by inspecting a limited sample of units and then making an accept/reject decision based on the observed number of nonconforming items. AQL is generally understood as a benchmark describing a quality level that is considered acceptable for a given sampling scheme; the plan links that benchmark to sample size and acceptance and rejection numbers.

How AQL-based acceptance sampling works

These plans are widely used in incoming inspection, supplier control, and routine production verification. The underlying idea is to replace 100% inspection with a statistically designed sample so that the condition of the lot can be judged efficiently and consistently. AQL-based systems are intended to balance inspection effort, decision reliability, and the practical realities of manufacturing. They do not guarantee defect-free goods; instead, they provide a structured method for deciding whether a lot is acceptable under a defined sampling regime.

What this withdrawn edition means

• This record is marked as withdrawn, so it is no longer active as a current standard.
• The title shows that the subject is attribute inspection rather than variable-based measurement.
• Lot-by-lot inspection is the central decision context for the sampling plans described by the standard family.
• AQL is a statistical reference point used in acceptance sampling, not a universal product quality guarantee.
