Statistical definitions in ICMSF / FSSAI three-class sampling plans:
In a three-class sampling plan defined by $(n, c, m, M)$:

• $n$: Total number of sample units drawn from a lot.
• $c$: Maximum allowable number of sample units with counts between $m$ and $M$.
• $m$: Microbiological limit that separates good quality from marginally acceptable quality. Counts $\le m$ represent an acceptable / good quality level, while counts between $m$ and $M$ are marginally acceptable.
• $M$: The hazardous threshold limit; any single count exceeding $M$ results in total lot rejection.
