Given that you said..."What is the design load, any agency approvals, ETL or UL?". It's hard to believe that your context of "agency" meant all or any local, state, regional or federal code enforcement departments.
In context, "any agency approvals," are defined by comas, as separate.
The point is, if the intent to establish a level of legitimacy to compete in the bldg. industry as a recognized supplier, UL, ETL and CSA approvals and listing are a prerequisite to agency approvals.
Were the intent be to simply develop a product that would be acquired by another, your reward will be commensurate with the front end progress you have accomplished.
Irrespective of that, I have never implied that I was referring to them. I have clearly been talking strictly about testing labs.
I know and thats why I was more interested in the broader application process, and Its pitfalls.
While you seem to still believe that even UL has some type of use approval authority, it's my belief that they don't.
You can't even backquote that, because their approvals are a function of their business model and are a prerequisite of a product being listed by them.
If it doesn't, they can't prevent it from being used.
Except that it cannot be used in a building, because an approved testing labs listing must be included in the application for building use approval.
They just don't give it a UL label. Any Government enforcement body could deny use, if the item was even subject to inspection.
Every government agency has a listing of all products approved for use, in buildings.
