++++
I would like to the widely accepted color fastness to light standard that are used by large US retailers. I understand the norm to be 20 hours. However, I need proof of this. Can you help.
Thanks,

Hi,
I have gone through your query on color fastness to light.
AATCC methods are used by all the US retailers and the requirement is expressed in terms of AFU. AFU stands for AATCC fading unit. Generally 10 AFU, 20 AFU, 40 AFU and 60 AFU are the requirements for different retailers depending on product type.
Would you please elaborate your query on color fastness to light so that I can provide you the correct information.
