Hi Ronan,
You are changing the product from await was listed so it would need a field
evaluation. I would ask one of the labs that does field evaluation but seems
pretty straight forward that since you are modifying the product from what was
originally tested would need a field evaluation. Typically can be done fast
and in a week or so depending on the test lab you get the field evaluation
from.
All the best,
Leonard (Leo) Eisner, P.E.
