Sampling and Inspection as per IS 8295 Part 2 (Clause 7.1 series)

• Sampling Plan: Single sampling plan with an Acceptable Quality Level (AQL) of 4.0% as per Table 2, IS 2500 (Part 1)-1973.
• Inspection Level: Use Inspection Level III as per Table 1, IS 2500 (Part 1)-1973.
• Standards Reference: Sampling and inspection procedures follow IS 2500 (Part 1)-1973, which covers inspection by attributes and defect counts.

Key Points:

Typical Sampling Procedure:

1. Determine lot size.
2. Select sample size from Table 1 (Inspection Level III).
3. Accept or reject lot based on number of defects allowed (from Table 2 for AQL 4.0%).

Example:

For a lot size of 500 units, Inspection Level III might specify a sample size of 80 units. If the number of defective units is ≤ acceptance number, accept the lot; else reject.

ISI Marking (Clause 8.1.1):

• Products conforming to this standard may bear the ISI Certification Mark, ensuring compliance and continuous quality control.
