Quality Control
Product testing schedules in textile manufacturing utilize variable inspection levels that adjust based on the supplier’s quality performance. The tightened inspection rules are a set of strict guidelines under ISO 2859 that increase the sample size and reduce the acceptance number when a factory fails to meet quality standards. This mechanism provides a stronger safeguard against defective shipments from suppliers with poor quality histories.
Sample Size
When a factory fails two out of five consecutive lots, the sampling plan automatically switches to a more rigorous level. The application of tightened inspection rules requires the inspector to draw and examine a larger number of garments from each batch, reducing the risk of accepting a lot with defects. This increased scrutiny makes it much harder for a sub-standard shipment to pass the inspection.
Risk Assessment
Sellers must demonstrate consistent quality over a series of consecutive batches to return to normal testing levels. Under tightened inspection rules, the factory must pass five consecutive lots without a single failure before the buyer will allow them to return to standard sampling. This strict requirement ensures that the supplier has fixed the root cause of the manufacturing defects.
Factory Consequence
Running these intensive checks increases the inspection time and the cost of quality control, which is often charged back to the factory. If the factory cannot pass under the tightened inspection rules for ten consecutive lots, the buyer has the right to stop all production and cancel future orders. This financial pressure motivates suppliers to maintain high manufacturing standards and resolve quality issues quickly.
