Light transmission standard?

Did anyone know wether there is an international standard for the light transmission?
The data testing in China is the same as data testing in Dutch? Which one is more legal or more accepttable?
As we now face a problem.Customer send us a light transmission report for not meet the requirementm, while what we test was meet the requirement. I donot know weather there is the difference between the instrument or testing method.
