Read the first 7 Quality Control & Testing flashcards as text

  1. Which ASTM standard covers the drop test for shipping containers?

    Answer: ASTM D5276

    ASTM D5276 is the standard method for drop testing of loaded containers by free fall.

  2. In statistical process control (SPC), a control chart showing individual measurements is called a:

    Answer: I-MR chart

    An I-MR (Individuals and Moving Range) chart is used when single measurements are taken rather than subgroups.

  3. What does the term 'headspace' refer to in flexible packaging quality evaluation?

    Answer: Air gap between product and seal

    Headspace is the volume of air or gas between the product surface and the package seal.

  4. Which test measures a package's resistance to crushing forces applied to its sides?

    Answer: Side compression test (SCT)

    The Side Compression Test (SCT) measures paperboard's resistance to compressive forces applied to its edges.

  5. A packaging line produces 10,000 units; 85 are defective. What is the defect rate in parts per million (PPM)?

    Answer: 8,500 PPM

    PPM = (defects / total) × 1,000,000 = (85/10,000) × 1,000,000 = 8,500 PPM.

  6. What is the purpose of a seal integrity test using dye penetration?

    Answer: Detect channels or voids in heat seals

    Dye penetration testing reveals channels, pinholes, or incomplete seals by wicking colored dye through any seal gaps.

  7. In acceptance sampling, the Acceptable Quality Level (AQL) defines:

    Answer: The worst tolerable process average for routine acceptance

    AQL is the maximum defect percentage that can still be considered satisfactory as a process average for routine acceptance.
