3 Terms and Definitions

GB/T 22181.1, terms and definitions GB/T 2421-1999 and GB/T 17309.1-1998 established applicable to this section.

4 measuring equipment constituted

Test equipment and/or operating conditions shall meet the test requirements of the regulations.

5 standard measurement conditions

5.1 Environmental conditions After the measurements must be sufficient warm-up time can be carried out under standard conditions. The so-called standard environmental conditions when the temperature is 25 ℃ ± 3 ℃, Relative humidity 25% to 85% and the atmospheric pressure is 86kPa ~ 106kPa environment. If the measurement in non-standard environment, it should be noted in the measurement report. Warm-up time should be more than 30min and γ correction is not performed in accordance with 15% of full-screen gray level of the input signal lights. If you do not use the same warm-up method recommended it should be noted in the report. 5.2 lighting conditions 5.2.1 darkroom conditions The amount of significant impact, should be used by subtracting the background light method, and indicated in the measurement report.
