Statistical Sampling Plans for Fabric Inspection
topic
Statistical sampling plans for fabric inspection use acceptance sampling procedures from ISO 2859 or equivalent national standards that specify inspection sample sizes and acceptance numbers based on lot size and acceptable quality level, providing statistically defined confidence that the accepted lot meets the specified defect rate, with the sampling plan balance between the producer's risk of rejecting good lots and the consumer's risk of accepting defective lots being calibrated to the commercial importance of each quality characteristic.
Role
Provides the statistically rigorous framework for fabric inspection that replaces 100 percent inspection of every metre with the economically feasible statistical sampling that provides defined confidence in lot quality, with sampling plan selection requiring the explicit definition of acceptable quality levels that forces both buyer and seller to quantify their quality requirements rather than relying on vague qualitative quality descriptions that lead to disputes when interpretation differs.
