PSAT (Preliminary Sample Acceptance Test)

It appears there might be a mix-up in terminology. The PSAT typically stands for Preliminary Scholastic Assessment Test, mainly used for college preparation in the United States. However, if you're referring to "Preliminary Sample Acceptance Test" in a different context, it could be a preliminary evaluation process where a sample product or system is tested to ensure it meets quality standards before full-scale production or deployment. This test helps identify issues early, ensuring that only acceptable samples proceed further, ultimately saving time and resources in quality control.
