  • Check color against Pantone reference β€” under natural light and indoor light
  • Check dimensions β€” length, width, height, thickness (allowable tolerance: Β±2%)
  • Check weight β€” consistent across samples
  • Check surface finish β€” no scratches, dents, uneven coating
  • Check labeling β€” correct barcodes, country of origin, safety warnings
  • Check logo placement β€” correct size, position, colors

B. Function Testing

  • Power on/off β€” 10 cycles minimum
  • All buttons/switches β€” 10 actuations each
  • Moving parts β€” smooth operation, no sticking
  • Electronic functions β€” test all modes/features
  • Battery compartment β€” fits correctly, contacts clean
  • Water resistance (if applicable) β€” test per spec

  • Inner packaging β€” product secure, no movement inside box
  • Accessories β€” all included, correct quantities
  • Manual/instructions β€” correct language, accurate content
