The packaged product shall be secured to the vibration table to prevent the package from moving off the vibration surface during test. 6.4.3. Test Axes. The packaged product shall undergo random profile vibration on all six (6) surfaces for a duration of 30 minutes per surface. 6.4.4. Random Vibration Spectrum. The total random vibration spectrum energy shall be 1.15 Grms and follow spectrum specified below. Random Vibration Spectrum Break Points Frequency (Hz) 1 4 100 200 PSD , G2/Hz 0.0001 0.01 0.01 0.001 6.4.5. Acceptance Criteria. The package and its contents should be inspected and evaluated for failure against the Acceptance Criteria. Ref. Section 4.0 Packaged Product Testing. 7. RGB settings The red, green and blue areas shall be measured at a digital input signal full white square pattern at 1680x1050, fH=65.3kHz/fV=60Hz mode with default color temperature setting (Normal Preset = 6500K). The u´ and v´ co-ordinates for R, G and B shall be setting as follows: Red u´ ≧ 0.411, v´ ≧ 0.503 Green u´ ≦ 0.140, v´ ≧ 0.548 Blue u´ ≦ 0.200, v´ ≦ 0.224 8. Color grayscale linearity The co-ordinates of color grayscale shall be measured at a digital input signal full grayscale square pattern at 640x480, fH=31.5 kHz/fV=60Hz mode with default color temperature setting (Normal Preset = 6500K). The measured u´ and v´ co-ordinates at grayscale 255,225,195,165,135,105 should meet the spec. as follows : Δu´v´= ((u´max-u´min)² + (v´max-v´min)²)½ ≦ 0.02
