Key Points on Sampling and Inspection from IS 8295 Part 1

1. Inspection Level & Sample Size:

   • Inspection should be conducted at Inspection Level III as specified in Table I of IS 2500 (Part 1)-1973.
   • Level III corresponds to a moderate sample size, suitable for general inspections.

2. Sampling Plan:

   • Employ a single sampling plan.
   • Use an Acceptable Quality Level (AQL) of 4.0% as outlined in Table 2 of IS 2500 (Part 1)-1973.
   • Acceptance of a lot depends on the defect count being within the acceptance number for the specified AQL.

3. Reference:

   • Sampling and inspection procedures must adhere strictly to IS 2500 (Part 1)-1973, which provides detailed tables for attribute sampling and defect evaluation.

Summary of Sampling Procedure:

    E -- Yes --> F[Accept Lot]
    E -- No --> G[Reject Lot]

Notes:

• IS 2500 tables dictate sample sizes and acceptance/rejection criteria based on lot quantity.
• AQL 4.0% balances the risks for both producers and consumers.
• Unless otherwise specified, these procedures ensure uniform quality control.

For detailed sampling tables, consult IS 2500 (Part 1) - 1973 directly.
