Black light integrity check Interval(ASTM E1444)

I would like to ask about the black light integrity check Interval According to E1444M (REV−16), different phrases for integrity can be identified.

Weekly checks are specified in TABLE 1 Required Verification Intervals.
However, Section 7.3.2 says to check every day.

Why is this difference?

Is there a checklist and procedure for black light integrity?
Looking forward to your response, thank you first.

ASTM E1444
7.3.2 Black Lights—Black lights used for evaluation purposesshall meet the requirements of 7.4.5. The minimumacceptable intensity is 1000 μW / cm2 at the surface beingexamined. Black lights shall be checked daily for cleanlinessand integrity and shall be cleaned, repaired or replaced asappropriate.

Hello Joonghwan,
I am not aware of a specific checklist, but I believe that the words following "integrity" indicate what is of interest here: condition (e.g. cracked/chipped/missing) of the UV-A radiation path (e.g. filter, splash guard) and radiation source (black light) itself.
