ISO 17025 and SAE J361 Question - MacBeth booth - Daylight filter was a D75

[ozziegood]

I am not sure if this questions should be in this section but here goes...

I have a MacBeth booth that was calibrated but I was told that my daylight filter was a D75 which is not to standard per SAEJ361 per the Detroit Color Council. They said the light should be a D65. Where can I find the standard without buying it to make sure that I what I need?

Any info would help!

4.1.1 Daylight capable of providing a color temperature of 6500 K ± 200 K at an illuminance of 1080 to 1730 lux (100 to 160 ft-candles). This source is typically provided by filtered Tungsten Halogen Lamps. The resulting
spectral power distribution of the incident light must be maintained to conform to ASTM E 308 and CIE Publication 51, Category A.


Revised Section 4.1.1 to increase illumination required to 1080 lux minimum (100 ft-candles) as recommended by multiple users within the industry and as supported by Detroit Colour Council Lighting Committee.




I would strongly recommend you purchase the standard since there are quite a few requirements for light booths contained within it.
