non-returnable wooden boxes for horticulture produce

IS 9590 - Scope & Sampling Key Points

• Scope: Covers specifications for boxes including dimensional and performance testing.
• Sampling for Dimensional Inspection (Clause 8.1):
  Sample sizes and acceptance criteria depend on lot size as per Table 1:

• Acceptance Criteria (Clause 8.4):

  • Lot accepted if failures ≤ acceptance number in Table 1.
  • For performance tests (e.g., vertical impact drop, stack load), no failures allowed.

• Purchaser Information (Clause 6.1):
  Purchaser must specify details when ordering as per the specification.

IS 9590 - Quality Control Key Points

Sampling for Dimensional Inspection (Clause 8.1 & Table 1)

• Acceptance Criteria (Clause 8.4):
  • Lot accepted if failures ≤ acceptance number (col 3).
  • For performance tests (vertical impact drop, stack load), no failures allowed.

Performance Tests (Summary)

• Vertical Impact Drop Test: For filled transport packages (Part IV).
• Stack Load Test: For filled transport packages (Part I).

Quick Reference Formula for Acceptance Sampling:

If

• ( n ) = sample size
• ( c ) = acceptance number (max allowable failures)

Then, lot acceptance if failures ( \leq c ).

flowchart TD
    A[Start: Lot Size] --> B{Lot Size ≤ 300?}
    B -- Yes --> C[Sample Size = 8, Accept ≤ 1 failure]
    B -- No --> D{Lot Size ≤ 500?}
    D -- Yes --> E[Sample Size = 13, Accept ≤ 1 failure]
    D -- No --> F{Lot Size ≤ 1000?}
    F -- Yes --> G[Sample Size = 20, Accept ≤ 2 failures]
    F -- No --> H{Lot Size ≤ 3000?}
    H -- Yes --> I[Sample Size = 32, Accept ≤ 3 failures]
    H -- No --> J[Sample Size = 50, Accept ≤ 5 failures]

This ensures statistically valid quality control during dimensional inspection and performance testing.
