Mintavizsgálat

Mintavizsgálat, often translated as "sample investigation" or "sampling inspection," is a quality control method where a portion of a batch of products is examined to determine whether the entire batch meets specified quality standards. Instead of inspecting every single item, which can be time-consuming and costly, a representative sample is selected and tested. The results from the sample are then used to infer the quality of the whole lot.

The core principle behind mintavizsgálat is that if a randomly selected sample exhibits acceptable quality, then the entire batch is likely to be acceptable. Conversely, if the sample fails to meet the criteria, the batch is usually rejected or subjected to further scrutiny. The size of the sample and the acceptable number of defects are determined by statistical sampling plans, which are designed to balance the risk of accepting a defective batch with the cost of inspection.

Mintavizsgálat is widely used in manufacturing, production, and quality assurance across various industries. It is particularly effective for large production runs where 100% inspection is impractical. Common applications include checking for defects in manufactured goods, verifying the purity of raw materials, and ensuring compliance with specifications before shipment. The effectiveness of mintavizsgálat relies heavily on the proper selection of a random and representative sample.
