[Column] "Sampling Inspection of Heat-Treated Products" is fundamentally a matter of "Probability Theory."

"Is it really sufficient to rely solely on inspection and sampling of heat-treated products?" *Explanatory materials are being provided.*

The quality of heat-treated products needs to be examined by investigating the internal structure of the metal, which necessitates the destruction of the product for testing. As a result, the reality is that destructive testing through sampling or visual inspection of the appearance is conducted, but there are issues with these inspections. Sampling inspection, which is widely adopted for the inspection of heat-treated products, involves taking samples at a certain ratio and comparing the inspection results with the criteria to determine the pass or fail of the entire lot. Ideally, thorough quality assurance would require 100% inspection, but due to the nature of fracture and destruction, it is limited to a certain number...
