        • Mechanical Stress: Simulate drops (1-meter height), button press cycles (10,000+), and vibration (IEC 60068-2-6).
        • Environmental Resistance: Test for dust (IP5X), water resistance (IPX4 for splash-proof models), and temperature cycling.
        • Visual Inspection: Check for cosmetic defects (scratches, misaligned parts, label errors) using automated optical inspection (AOI) systems.
        • Final Inspection Before Packaging
        • 100% Electrical Safety Test: Verify insulation resistance, leakage current, and ground continuity for battery-powered models.
        • Compliance Label Verification: Ensure CE, FCC, or other required markings are correctly affixed and legible.
        • Packaging Integrity: Confirm calculators are securely packed with anti-static materials, tamper-evident seals, and compliance documentation (e.g., MSDS for batteries).
        • Pre-Shipment Inspection for Bulk Calculator Orders

          A pre-shipment inspection (PSI) is the final quality gate before calculators are dispatched, ensuring compliance and defect-free delivery. The process involves a structured examination of a statistically significant sample (typically 5–10% of the batch) and documentation of findings.

          Key Inspection Steps
          1. Documentation Review:

        • Verify compliance certificates (CE, FCC, RoHS), test reports, and supplier declarations of conformity (DoC).
        • Cross-check batch numbers with production records to confirm traceability.
        • 2. Physical Inspection:

        • External Examination: Look for scratches, misprints, or missing components (e.g., batteries, manuals).
        • Functional Testing: Perform a subset of the in-process tests (e.g., basic arithmetic, display functionality) on 100% of the sample if defects exceed an acceptable threshold (e.g., >2% failure rate).
        • Randomized Testing: Use a stratified sampling method to test calculators from different production shifts or batches.
        • 3. Defect Documentation:

        • Defect Logging: Record defects using a standardized form, including:
        • Defect type (e.g., display flickering, button failure).
        • Quantity affected.
        • Root cause hypothesis (e.g., soldering issue, assembly error).
        • Photographic evidence for visual defects.
        • Non-Conformance Report (NCR): Issue an NCR to the supplier detailing findings, required corrective actions (e.g., rework, replacement), and deadlines.
        • 4. Compliance Validation:

        • Re-test a subset of units for critical compliance parameters (e.g., EMC, safety) if prior tests were inconclusive.
        • Confirm that all calculators meet labeled specifications (e.g., battery life, operating temperature range).
